Re: [gentoo-user] Re: Reinstall

[Bill Kenworthy]

I suggest either taking a full dd|bzip2 style backup of the hardisk to 
removable media  for the simplest reinstall. Compliment with borgbackup or 
dervish for space efficient backups to capture more recent changes.  Reinstall 
is the reverse .. lay down the dd image  update from the backups with rsync. No 
need to get caught in messy  install routines that will take a lot longer with 
an uncertain outcome.  I have a few arm systems and seem to be doing it at 
least once a month as the sdcards reach their end of life.

Re: [gentoo-user] LVM and moving things around

[Bill Kenworthy]

Rsync has a bwlimit argument which helps here. Note that rsync copies the whole 
file on what it considers local storage (which can be mounted network shares) 
... this can cause a real slowdown.

Sorry, so many typos, here it is again :(

Hi, I am trying to install the sslpsk python module using pip for python (for 
tuya-convert) but its not working - python3 works, python2 doesn't. It was 
working a  few months back on a different system.

I have installed python 2.7 from portage and followed the wiki (set 
python_targets, emerge -NuDv etc.), however pip seems to only know how to 
install for python3.

For python 2.7 do I need to go completely manual for installation using old 
packages?

Re: [gentoo-user] gentoo-sources kernel not seeing 4G ram

Hi Rafael, fixed thanks to the link you gave - needed  apatch to a dts

So I now have a heavily patched mainline based (gentoo-sources) kernel 
with gentoo aarch64/openrc userland running on the n2 as a headless

Nice,

Hi, not sure anyone can help with this as its a bit off the reservation :)

I have a Odroid N2 with 4G ram that is only seeing 1G. (even from right at
boot looking at dmesg).  Its part of the board so its not a connector issue.

Kernel is gentoo-sources-5.4.8 with the AMLOGIC armv8 relevant bits copied
from the 4.9 series original hardkernel sources.  OS is gentoo AARCH64.  This
all built and runs quite nicely, but cant see the full 4G ram that should be
there.

Ive attached my latest kernel config in the hope that someone can see
something Ive missed (presuming it isn't an inherent problem in the way I
have gone about this) - looking at the config, diffing it against the hardkernel
source etc. hasn't helped.  Below is the start of dmesg up to the memory
statement.

My next move will be to go back to the 4.9 supplied kernel and make sure it
isn't hardware failure (unlikely, but ...)

Re: [gentoo-user] Guidance on using Gentoo to clone a Win 10 system drive

[Bill Kenworthy]

Hi Mark,
    was your old version Win10 PRO" as well? - as far as I know a 
reinstall will only validate if the hardware as recorded at MS mostly 
matches and its the same version.  Cloning via dd, then running through 
the re-validation checks, then making changes in small steps is the only 
way I have been able to make it work despite what is written in the link 
below.

Michael,

automatically validate and I'd be good to go. so far, after 2 hours it 
hasn't done that but I'll give it awhile and see what happens. As it 
only took an hour I might still try the disk copy path and see if that 
comes up validated as that would also transfer the couple of 
applications I have on the original hard drive.

On the machine with the drive attached
mbuffer -i /dev/mydrive | xz -e -9 | mbuffer -O hostname:port

On a machine with storage space
mbuffer -I port -o /path/to/storage.xz

To make a backup.


In terms of cloning windows to another harddrive in
general, as long as the destination harddrive is large
enough to fit the original drive without issues, simply
running:

dd if=/dev/original of=/dev/destination
(I prefer dcfldd, personally)

Is enough. Run gparted (the graphical version, for nice
wizards) after, and it'll fixup your partition table for
you to match the new size, and you can re-size any
partitions you have to make them match as well. I do
exactly this all the time and have yet to have a problem.

As for windows 10 licensing, don't trust me on this
blindly, but your license should be tied to the hardware
fingerprint of the laptop. So even installing windows
fresh on your new SSD should result in Windows activating
automatically. In fact, you might want to take this
opportunity to try that out, to get a completely fresh
installation without the decade of old cruft built up by
window's lack of a package manager.

If it doesn't activate as soon as you plug in an ethernet
cable, you can just wipe your SSD and copy your old
installation as discussed already.

Howdy,

As some may recall, I have a 8TB external SATA hard drive that I do back
ups on.  Usually, I back up once a day, more often if needed.  Usually I
turn the power on, mount it, do the back ups, unmount and turn the power
back off.  Usually it is powered up for 5 minutes or so.  When I unmount
it tho, I sometimes notice it is still doing something.  I can feel the
mechanism for the heads moving.  It has a slight vibration to it.
Questions are, what is it doing and should I let it finish before
powering it off?  I'd assume that once it in unmounted, the copy process
is done so the files are safe.  I guess it is doing some sort of
internal checks or something but I'm not sure.

There is some delay with data still in the buffers between rsync/cp/tar/what-
ever saying it's finished on your terminal and the drive itself finishing
storing the data on the platters.

If you look at vmstat, or keep an eye on Gkrelm you'll see what I mean.
Normally, if you try to unmount a drive while it is still being written to,
the umount/udisks command will complain the drive is busy.


When it does it for a somewhat short period of time, I can understand
that.  It's one reason I try to leave it on when it "feels" that it is
still busy.  Thing is, there are times when it goes on for 30 minutes or
more.  At those times, even a USB stick should be done.  One would think
at least.  It makes me curious as to what it is doing in that case.
Still, I'd rather the unmount command force a wait until it is done.
Honestly, I wouldn't want a drive or software that says something is
done when it isn't.  It's not good even when shutting a system down.
Given the speed of drives, I would think a few seconds at most.  Best to
be safe.  ;-)  I just wonder, is it doing two different things?  One
when it is busy for short periods of time and something else when it
goes on for a while.  This is what sort of puzzles me.  Selftest maybe??


Is it safe to turn it off even tho it is doing whatever it is doing?
Should I wait?  Does it matter?

Thanks.

Dale

:-)  :-)

If you wait for a few seconds after the backup is completed before you unmount
the drive, you should be OK.  Although it may slow down or any LEDs flash less
frequently the drive may not stop spinning, unless there is some power save
process taking control of it.


Given the speed, it is likely done when I tell the KDE thingy to
unmount.  Usually, I start the backup and walk away for a few minutes.
I do it with one of my scripts, if one can call what I do a script, and
it does the date command at the end.  Even if there was a lot of
changes, I can tell how long it was completed.  I try to give it a
couple minutes.  Still, good point.  This is one reason I'm asking about
this.  It's hard to know exactly what is going on here.


P. S. Down to last router that was discussed in another thread so I
bought it while they had it.  Price may go up if I didn't.  Did more
research on old modem, it is risky to try to convert to AT  Some say
not possible.

Right, ISP controlled firmware typically requires re-flashing the device with
the new ISP's firmware version.  In some cases even the boot code needs
replacing.  Should you flash the router with a wrong firmware build, you could
sometimes derive a door stop without additional cost.  In this case you'll
need a JTAG and access to its circuit board with an OEM boot/firmware version
to recover it.  In most cases OEMs support lines will redirect you to your
ISP, who run an overseas support line and will ask you to reboot your
MSWindows PC ... O_o

This is a reason I avoid these kind of routers as much as I can.


Keep in mind, two pieces of hardware.  Router for the first two
sentences and Modem for next two.  Tried to be short so . . . . Anyway,
router should be flashable with Openwrt.  It's a slightly older model.
New model may be ready for flashing in a year or two but not so much at
the moment so I went with the older model. The modem, I never could find
the firmware.  I found links to it but those links ended up being dead.
Even if I had it, it was unlikely to work.  Possible but I'd be
concerned about its stability and such even if it did take it. I have a
modem and router on the way.  I just didn't want to miss the deal on the
router.  They had several a couple weeks or so ago.  I got the last
one.  Waiting for their arrival.

Dale

:-)  :-)

Oh, I may post and see if anyone needs a Frontier modem later.  Maybe
someone on here could use a spare or just needs one period, moving or
something.  Modem is wireless with a router as well.  Nice modem I guess.



Try atop from sys-process/atop - it will show you how busy individual

Hints anyone?

One further point, I cant boot off the usb and pivotroot to the eMMC 
root - again no eMMC modules loaded.  But once the usb root is running, 
the eMMC modules are loaded.  Its looking like the kernel device 
detection needs real root which is ... odd!

I've reinstalled gentoo from the gentoo repository and now my power

I have this, but it doesn't work:

$ cat  /etc/acpi/events/powerbtn
event=button[ /]power.*
action=/sbin/poweroff

I don't have the above file, only /etc/acpi/events/default, which invokes '/
etc/acpi/default.sh' and that's all my systems need to shutdown gracefully
when I press the power button.

NOTE:  I only press the power button momentarily.  If I press and keep pressed
the power button for a few seconds, then the system powers off instantly
without a graceful shutdown (a.k.a. I then will get a hard shutdown with no
disk syncing or flushing of caches).



On a different gentoo system I have, I have just the one line, the
action line, in that file and the power-button works fine (whether
there's causation there or not, I have no idea :-) )

Judging from my systems I don't think the file you are using is necessary,
unless this is supposed to be a fix for some MoBos which do not work as
expected.



I generally do /not/ press the power button while in my window manager,
but first when I've logged off.  Since that wasn't working, I tried
inside my window manager ... I got a just a couple of lines that looked
like they came from shutdown(), but too few (couldn't read them).

Then, on startup, the filesystems needed fscking!!!

Does the same thing happen if you run '/sbin/shutdown -h now' ?



Hi,
    have you installed elogind? - for me it took over and replaced the 
acpi functions by intercepting the call beforehand.  It also hijacks 
suspend hibernate.


A couple of weks back it "broke" and is is recording the power button is 
pressed but doesnt take the actions required by its config file.  
"loginctl suspend" works ... sort of ...

It works for me - but its annoying in that its inherited some parts of
the systemd "stuff you - I dont care, I am going to take it over anyway"
attitude.  For me its laptop suspend/hibernate - its never worked as
well as previous scripts and it seems it cant be undone.  Its also quite
chatty in the logs - also annoying.

I know the author is responsive and has done a good job in just being
able to get it to work, but he has started with crapware and it shows.

[gentoo-user] dhcpcd not updating interface IP

[Bill Kenworthy]

Since Augusts dhcpcd update to net-misc/dhcpcd-7.2.3 dhcpcd has often
missed actually updating the interface when a change happens.  Even
issuing a manual dhcpcd -n  doesn't work, but restarting the
interface gets everything working again.  Its the WAN interface to the
ISP so can only see my side of the link.

Is anyone else seeing this?

Also, check if you have cpu isolation turned off in your kernel - when

2 out of 7 systems have this style symlink - one is quite old (many
years), the other only one year or so. How system level links would
happen in this way is strange.  Both systems have been through (in some
cases multiple) restores from backup which may have been the cause.

Sounds like you are using gnome/systemd ... thats a whole other box of

Re: [gentoo-user] udisks and exfat

[Bill Kenworthy]

Got sidetracked - turns out fuse and exfat on usb do not play well with
mounts as a user due to changes late last year.  It can now only be
mounted/unmounted by root.

The second part (also due to fuse) is that to stop fuse (silently as ls
still showed the execute bit set) from interfering with execution of
files on the mounted device) it must be mounted as the user under a user
owned directory such as /home/user (mount cannot deal with this - it did
in the past, but something has changed).  So the solution is to mount
via root as the user you want (via sudo) under a mount point in the
users home.  This may all be unique to fuse-exfat, and which versions of
everything involved as I saw one email on the mechanics of the changes
saying fat is handled a little differently due to a different use
scenario.  And ext2/3/4 etc don't have the problem at all.  Auto-mount
on device plugin still doesn't happen so thats next on my list.

/etc/fstab:

/dev/sda1   /home/myuser/mnt   auto   
rw,auto,exec,uid=1000,gid=1000,users,user=myuser   0 0

I will grab the info tomorrow.  I was hoping there is a guide somewhere
as it happens on multiple systems and from what I have read its by
design.  There is so much old info on the net on how to fix the problem
with it appearing to be implemented differently on each major distro,
and none of the work arounds/fixes work on gentoo.

[gentoo-user] udisks and exfat

[Bill Kenworthy]

How does one execute a file on an exfat formatted usb key?

I have an encryption app that must be executed from the drive to work
(secure-stick).  Works great in windows, linux is a real pain because I
think udisks is forcing execute off and I cant overide it.

[gentoo-user] elogind problem

[Bill Kenworthy]

Hi,

    I have just replaced console-kit with elogind and while its fixed my
X server problems, its brought some downsides as well.  Primarily, I
used to use acpi to hibernate but elogind has coopted the power button
so acpid doesnt get the signal, and added a suspend to lid closure but
then I cant run scripts to recover the touch screen etc.
(MSsurfacePro4).  I could deal with that except the docs for
systemd-logind (the elogind docs refer there) say they have removed the
possibility run arbitrary scripts from logind (and so I assume also
elogind). 

So how can I recover the hardware to a working state using elogind? 
Worst case would seem to be disable elogind hibernate/suspend in its
config file and handle it old school but is there a better way using
elogind?

I would guess:

1. that the portage version is meant for the internal use of portage
(hence why its "in an odd spot") and is divorced from the user package.

2. gentoolkit has the user version as "equery f gentoolkit" shows a
/usr/bin/symlink.

Hi Rich, no grub! A rpi uses a custom loader (apparently the GPU starts
the boot process).  I'll investigate if it can passthrough a UUID. 
Looks like next stop is the pi forums, but most use their kernel, not a
custom one.

[gentoo-user] dracut and UUID's

[Bill Kenworthy]

Hi all,

    I have cloned a gentoo image for a raspberry pi to another sdcard. 
It fails to boot because the storage uuid's have changed and dracut has
the previous uuid's stored internally.  Is there a way around this
without changing the new storage's uuids back to match the original (its
bad practise to duplicate uuids) or using an original rpi kerneal and
rebuild the custom one?

[gentoo-user] xorg 1.20.x not working

[Bill Kenworthy]

Hi,

I have a problem with any of the xorg-server 1.20.x series where I can
start simple apps like xterm but more complexapps like firefox and
thunderbird (for example) hang X with no erros in dmessage, log,
Xorg.0.log, .xsession-errors etc.  The mouse can move but no clicks are
accepted.  I have also recently run emerge -ep  with the profile upgrade
(using 1.19 as I needed to use the system at the time) and a previous
rebuild of almost everything with 1.20 installed with no change.

The system has been running fine on xorg versions up to 1.19 for over a
year and I can wind it back to 1.19 and everything works again.


Any hints on how to get 1.20 working would be appreciated as 1.19 is
about to be removed from the tree.

Hi Rich, unfortunately 4.18.20 is the last one that supports the ipts
patch set (surface pro4 touch screen) ... its flaky, bu the earlier ones
are even worse so going to a LT kernel isnt really useful.  I hope they
can get a 4.19 or 4.20 patch set up soon, but apparently kernel changes
have made it difficult. 4.19 without touch does work with only minor
problems, but of course with no touch screen.

sys-kernel/gentoo-sources-4.18.20 but as its no longer in the tree I
checked the attic but it looks like it is only cvs and no longer in use
for git.

I couldnt find gentoo sources in the server linked to from the cvs
attic. Is there an equivalent to the attic for git, or a stanza to
retrieve it?

This happens to me when ssh'ing into various machines with a different
console size.  With screen in xfce-terminal I use F11 to maximise/resize
the screen to force the screen to redraw correctly.

Is this a common key map to the redraw function and does it work for you?

Grepping .config will only work sometimes - If its enabled it will be

Only sure way that I am aware of is to use the search function "\" from

[gentoo-user] no file system found for kernel 4.14.78

Kernel 4.14.78 has been released and I have a fail upgrading one system
- fails to mount root vfs but oops instead of dropping to a recovery shell:

Same boot stanza as 4.14.65, one unrelated (RCU) difference between .configs

Has anyone else had this problem upgrading? - its difficult to FF as the

[gentoo-user] xorg-server-1.20* failure

[Bill Kenworthy]

Hi, I have a problem with xorg-server 1.20*.


LXDM starts, but on login xfce4 freezes with the panel, xfce4-terminal
logo and a blank background.  The mouse moves but no response to
clicking anything on the panel.  startx as a user or root just goes to a
black screen with a blinking cursor. Nothing amiss in the Xorg, dmesg or
syslog logs that I can see.

So far I rebuilt a lot of X, emerge -ep xfce4-meta (some 500 packages)
with no change.

This is the same for 1.20, 1.20.1 and now 1.20.2.  The older 1.19 series
worked fine.

Hardware is MS Surface pro4 with gentoo-sources with Jake Days IPTS
patches - IPTS mouse works along with the touchpad.

There were a few bugs causing somewhat similar symptoms but 1.20.1 was
supposed to fix them - has anyone suggestions on what to fix?

I am suffering same thing/symptoms.  It will often (but not always)
power off on a straight shutdown, but rarely if ever on hibernate.  Been
happening since a late 4.14 and and still happening on 4.18.8.  Race
condition?

Everything shuts down and the screen  shows "[timestamp] Reboot: Power
down" - I have to hold down the power button for 10-15 seconds to remove
power.

and another category - do a proper backup using backup software. 
Copying the raw partition has some disadvantages - difficult (but not
impossible) if you want to restore to new hardware (on failure), harder
to restore if you decide to change the underlying filesystem, takes far
longer to copy than a backup but the biggest problem is no versioning. 
Raw copies are great if you want to do an immediate restore, but hard
work or useless after a few days of changes.  Think of it this way - in
almost all cases its the data that's important, not whats holding the data.

I would think the cost of setting it up and running a fridge would add
up to hard drive cost over a couple of years anyway (at least for what
we pay in Western Australia :)  In a humid environment you would need to
be very careful of condensation, and a sealed system will still need a
way to transfer the heat as if the cooling fails, it will cook itself
very fast

I have the fans set to spin up faster at 35c and above.  Without the
fans they sit around 45c on a typical day and use.  I have found that in
an enclosure its just as important to have good conduction of heat
(disks mounted to the metal frame) and clear the heated air out of the
enclosure as flowing air over the disks.

Here it gets to 40c+ (>100F) and sometimes humid (not far from the
ocean).  Cooling is fans only, and I have 4 WD Green, 2 WD red and two
seagates (all 2G, in 2x btrfs raid 10) and a few intel and samsung SSD's
(for bcache and system disks) that run ~16 hrs a day with no failures
for the last few years (~10).


Sometimes its better to play the odds.

If you can locate it to a location range, you can use a kernel argument
to exclude that area of memory.  The hard part is to map the range.  Had
one system running that way for years.

Hi Dale,

    what you are talking about is not a real backup but a single copy of
your data that may or may not be complete (the delete option you
mention) at a single point in time - not quite as useful as a proper
versioned backup.  Whatever your choice, also look at the restore
procedure - very important.


Have a look at Dirvish or borgbackup (both in portage) for what they can
do.  Having a space efficient store at regular points of time is a
lifesaver at times. To restore from dirvish its a copy from the selected
tree.  With borg its either restore with a command, or mount it and copy
the data out of the mount.

http://dirvish.org/

https://www.borgbackup.org/

I moved from dirvish to borg 12 months ago and they are both excellent.

[gentoo-user] OT: Open source document management system

Hi all

    I have been looking for an opensource document management system ...
there are a few but none of the ones I have come across are in portage.

Are there any DMS's in portage at all?  Otherwise, can someone suggest
ones worth trying as most seem suitable from their websites but its
going to time and labor to start testing them outside portage?

Yes there was the original news item - but nothing about the problems
this caused, and the back and forwarding which is causing me grief.  It
is only switching targets, but when you have problems and decide to
remove 3.6 and recompile, then having to go through it all again
without  proper information it has impact.  A news item is supposed to
give information ... I am not criticising the changes itself (sh..
happens), but being left in the dark about it.

Brings up all the manifest files so I'll clean them out, resync and
see.  I do have rsync-verify set but I would not have thought that the
problem.  The system was converted to git syncing (by deletion and
recreating) soon after git became available so it could be something
ancient is the cause.  None of the docs I have examined seem to cover
portage and git problems very well.

 I'm seeing this too. For me `app-crypt/gentoo-keys` is somehow no longer
 installed and `/var/lib/gentoo/gkeys` is missing. I have no idea how this
 happened. Perhaps it somehow got into `emerge --depclean` and I didn't
 catch it.

I tried the host hack - still fails though a different message.  I
suspect the keyservers are not the problem because:

"gpg --homedir /var/lib/gentoo/gkeys/keyrings/gentoo/release --refresh-keys"

mostly works fine (with or without the hosts hack).

But I have never had a successful run with emerge --sync

[gentoo-user] semi OT: Displayport

[Bill Kenworthy]

Hi all,

    I have a surface4 pro and use a vga adapter on the displayport
connection.  This works when manually (Xorg, XFCE4 and xrandr)
configured to various external monitors and data projectors.

I am trying to automate the process but plugging in the display port
adapter does not generate any messages via logging or dmesg (kernel is
gentoo-sources-4.16.12 patched to work with the ipts touchscreen) to
hook a udev rule into. 

Can anyone suggest a way to detect when the displayport adapter is
plugged in?

[gentoo-user] apache mod_wsgi radicale and passing in an environment variable

[Bill Kenworthy]

Hi all,

    how does one set an environment variable for Apache mod_wsgi on gentoo?

I am using the radicale wsgi module and it requires the config file to
be passed in from the environment to be set in the environment.  The
documents recommend something like whats below, but is not specific on
saying where it is to be set in my configuration.

|env = RADICALE_CONFIG=/etc/radicale/config|

Hi,

    is it possible to filter out a package (chromium) from from emerge
world on the commandline?  Using files is a pain when I just want to

I am referring to putty as the windows client (my view of the process) -
the vpn client is proxytunnel on windows connecting out to the server
which is an external stunnel on gentoo from your point of view.  The
secret is getting the two to talk to each other and thats where it gets
interesting - a method I used in the past is internally have a script
scraping a webpage (external) and when it gets a change it wants,
initiate a connection (IP number change for a permanaent link on a
dynamic IP, or other instruction - actually used a html comment on my
home web server index page).  A more common method is to initiate a test
connection every few minutes and close/go back to waiting if there is no
connection.  Zebedee which I used for years as a port tunnel (very good
and flexible) has a mode where it can initiate connections when there is
no public visibility.  If both ends are behind a secure gateway/NAT -
you need a third machine to coordinate the process.

If its all too hard, can you drop a raspberry pi trojan on the network
which gets away from the restrictions running windows?  At the end of
the day, its up to you and the local admins as to how much funny
business they will put up with but its just a technical problem in
moving packets around.

Might need a third party vpn server in the cloud that both ends connect
to as clients and route between?  A stunserver like VoIP uses will help
there.

Also try a proxytunnel/stunnel using port 443 and use that to bounce
openvpn or a putty (ssh) port tunnel through the networks https proxy. 
Inefficient but gets ssh, web pages and small downloads through
problematic networks nicely.  Double wrapping in ssl with end-to-end
protection via openvpn takes care of privacy when MITM SSL proxies are
used (yes they exist)   Note that openvpn can be used peer to peer
though client to server is a bit more secure.  In my setup, the client
is windows and the server is gentoo on a dynamic IP.  For really
paranoid networks, there are other ways but I have found this handles
most cases which are either my android phone, laptop using openvpn on
locked down wifi networks or ssh (putty) on windows hosts.

Pretty stable for me - ymmv.  What is annoying is sometimes complex
pages do not load properly (e.g., job application sites which seem to
have a lot of JavaScript running in the background.- possibly due to add
blocking while FF when it works is vanilla)

I found the bug against gcc for it (not qtgui which is why I couldnt
find any info on the problem). Seems that its one of the source packages
polutes the build environment at some point in the past so I have to go

[gentoo-user] OT: aggregating filesystem

[Bill Kenworthy]

Is there such a thing as a linux network filesystem that aggregates
storage across a few machines?  I am not talking about dedicated chunk
servers and the like, but something that can make available a the unused
space on a number of machines (desktops, servers, ...) by aggregating
and making available the space to the network. Is afs (or coda?) what I
am after?

I have used ceph, but its minimum requirements are way to heavy for a
small network,moosefs looks to be similar and as dedicated storage,
that's not what I am after.

    are there hibernation (to disk) issues with gentoo-sources 4.15.1?

1. do another backup
2. take your last good binary package and unpack it in the root
directory - it is an "image" of that package as it sits in the file system.
3. rebuild that version of glibc by overiding emerge - comment out "die
"aborting to save your system" in /usr/portage/eclass/toolchain-glibc.eclass

I have done this a couple of times with gcc (when manual deletes have
gone rogue) but it should work with glibc as you have not recompiled any
new packages.

I have used .localdomain for years without issue.  VLANS
(wifi.localdomain, lan.localdomain etc.) are great if you have the
hardware to do it.

Using non-official TLD internally shouldn't cause any problems (unless
someone is "stupid").

[gentoo-user] cross compiling arm with 17 profiles.

[Bill Kenworthy]

Something I cant figure out:

ARM is still on the 13 profiles - should an amd64 system used to cross
compile for arm (Raspberry Pi's) be left on the 13 profiles or 17 will
work fine?

Got it! Needed ssh keys for portage@remote from root@local.  Its working
but no idea why its only this machine that required it.

No, all machines are set up as keyless ssh - git has never needed it
there.  In frustration I created keys and set portage up as a keyless
ssh account as well, no change.

[gentoo-user] git wants a password to portage sync

[Bill Kenworthy]

I use a central machine that all other gentoo machines pull portage
updates from using emerge set up for git.

Some 10+ physical and virtual machines work fine.

A newly installed machine wants a git password to do the git pull where
as no other machine does.  Tried setting up keys for it on the remote
machine (user portage which is who git pulls come from) and ssh login
works fine, git demands a password.

Any hints because its got me beat!

Your system is somewhat broken I think.  You need to look at each
package and resolve the problem - possibly stray entries in one of the
package files or world.  Have you done a depclean recently?

Re: [gentoo-user] Again, emerge -e @world related questions...

[Bill Kenworthy]

I think you are looking for problems that are not there.  Almost
finished recompiling the surface4 pro and have one compile failure I
have not looked at - the original palemoon is still working.  The
hibernate to disk just failed so it rebooted from scratch and I could
continue working on it while it finished but a full desktop is so much
nicer :)  I have some other (slower) systems in earlier stages of the
rebuild that are working fine.


do an emerge -ep world > a
edit a to something like below then "bash a" to run it:
emerge -v =kde-frameworks/kdelibs4support-5.37.0  && \
emerge -v =kde-apps/kio-extras-17.08.3  && \
emerge -v =kde-plasma/user-manager-5.10.5  && \
emerge -v =kde-frameworks/kactivities-stats-5.37.0  && \
emerge -v =kde-apps/okular-17.08.3  && \
blah blah blah ...

When an emerge stops, either fix it or comment it out for later.  Edit
"a" and delete finished builds and go again - in the meantime keep
working ...

[gentoo-user] OT: btrfs raid 5/6

[Bill Kenworthy]

Hi all,
I need to expand two bcache fronted 4xdisk btrfs raid 10's - this
requires purchasing 4 drives (and one system does not have room for two
more drives) so I am trying to see if using raid 5 is an option

I have been trying to find if btrfs raid 5/6 is stable enough to use but
while there is mention of improvements in kernel 4.12, and fixes for the
write hole problem I cant see any reports that its "working fine now"
though there is a phoronix article saying Oracle is using it since the
fixes.

Is anyone here successfully using btrfs raid 5/6?  What is the status of
scrub and self healing?  The btrfs wiki is woefully out of date :(

Same on multiple systems - emerge boost worked fine, then do world.
