 If an overlay is not listed on zugaina, these days it tends to be on

I would concur with Alan. The zugaina site is a very valuable resource.

I happen to have an overlay in Layman and I have contacted Ycarus (who runs
the zugaina site) when
one of my packages wasn't sync'd with Layman. Apparently his site pulls in
the overlays on an automated basis
(cron job style). It is pretty quick to update/stay in sync though.

I tend to look out for quality (or lack of) 3rd-party ebuilds by running
repoman over them. Stale Overlays are pretty
easy to spot as well... :-)

 Apart from kernel level USB suspend. There are settings in /sys/

 I would assume Fedora disables that for keyboards and mice (think

I browsed their udev rules and found some rules pointing in that

But they seem to do it specifically, yes -

# cat /sys/module/usbcore/parameters/autosuspend

# my keyboard
# cat /sys/bus/usb/devices/3-1.6/power/control
on

I assume it won't hurt much if I disable USB autosuspend in general for
now? Power savings should be minimal, right? (desktop here, AC etc)


Doesn't the powertop utility have a facility to do this per-device and to
see what the current power-save settings are per-device? Surely a bit
easier to use than directly messing about with udev rules?

Re: [gentoo-user] Easy (cough) way to build earlier gentoo-sources 3.18.x kernel?

[Bob Wya]

Sorry folks - I guess I've made a right dogs dinner of this whole thread...
I'll make more efforts not to be that noob next time :-)

But I've got the information I needed about how to build old
gentoo-sources kernels. So thanks!

I've done my tests and the outcome is:

3.8.8 (gentoo-sources - manually built)
= NO nfs suspend issue

3.8.9 (gentoo-sources - manually built - nfs specific patches, removed
from 1008_linux-3.18.9.patch)
= NO nfs suspend issue

3.8.9 (gentoo-sources, stock)
= boot hangs with pNFS block error

3.8.10 (gentoo-sources, stock)
= nfs suspend issue

Anyway that's pretty much what the ML thread was kicked off to achieve
- so thanks all! Plus I've written a
little script for ordered patch application - so that might come in
useful at some point :-)

Just wondering in passing what the motivation is for kernel eclass
dropping support for automated
building of, what many would consider, very recent kernel revisions?

Could support not be retained (for renaming kernel versions to build
older revisions)
- but say masking off these versions as not security patched / maintained?

Personally I was quite surprised I couldn't just rename the stock
gentoo-sources ebuild to say
gentoo-sources-3.18.8.ebuild to pull that kernel revision with
automated patching...
But perhaps I'm just showing my inexperience / naivety in this matter?

 I wasn't suggesting renaming the ebuild but downloading the older

 easier to just apply the patches manually in this case.

 gentoo-sources uses both the base and extra patchsets from genpatches.

Re: [gentoo-user] {OT} offline backups

I own a BluRay writer. A few years ago I had a serious attempt at BluRay
archival storage. It works - but it's slow (very slow) and expensive. Then
there is the cost / GB - that remains high due to the low volume of BD-RE
media sales...

Now factor in the super high volume of MLC NAND flash SSDs prevalent on
today's mass market. A good SSD will last far longer than the slowly
degrading dye on a BD-RE disc. Just dust off an Intel SSD every 5 years and
to run a level 2 Spinrite scan on it and it could potentially hold data for
decades... No optical media could match that...

Re: [gentoo-user] the new ssd, is it happy?

[Bob Wya]

So it probably is Samsung's dodgy firmware not working with the SATA-3.0
extensions (aka SATA 3.1).

Like I mentioned I can't even run my Samsung SSD's @6Gbit because none of
the models I own support deterministic trim - which is a much bigger
problem than yours! I assumed the 850 Pro would support deterministic trim
- as the 840 Pro models supported it - but hell no!

I wouldn't rely on any firmware updates from Samsung to fix any of this
stuff... It has to be really, really bad - like the 840 issues - before
they'll pull their finger out.

I'll certainly be raising a support issue, over the lack of
non-deterministic trim support in the 850 Pro firmware, but I expect that
will get as far as my LSI Support issue did... :-(

Re: [gentoo-user] the new ssd, is it happy?

[Bob Wya]

This made me recall having to download and alter a Windows SATA Host
Controller driver. For some reason I had to get hold of an 6Gbyte
development .iso to do this (that's Microsoft for you)... Now that was fun
and games!! Basically because the SATA controller driver tried to enable
NCQ (I can't remember which now!!) for some old Hitachi IDE drives - I had
hooked these up via a SATA-PATA bridge - the bridge said NCQ - YES!! - the
drive said NCQ - NO!!. The drives would lock up Windows when I hooked them
up to the controller and start twanging constantly as they were reset,
over and over again...

I read through that bug report - interesting. It shouldn't be too hard for
you add a User patch for your Gentoo kernel - to force-ably disable the
attempt to negotiate SATA 3.1 and T13 ATA ACS-3 support - for the SATA
connection. Since (I guess) you are building the kernel from source anyway!

Basically your 850 EVO returns RECEIVE/SEND FPDMA QUEUED supported when
initially queried
Then when the (Linux) kernel tries to actually queue these commands - the
850 EVO firmware says Uhhhmm, duh - no I don't know how to do that one!!

Just out of interest what make is the Host Controller on your
motherboard... Is it a Intel one? Or some crappy addon chipset? Perhaps you
could post the output of lscpi (with lots of - flags - just the Host
Controller bit)?

I'm starting get the feeling that Samsung take some very caliver shortcuts
with the QC on their SSDs. I've recently bought a Samsung 850 Pro - sucker
- as I have already experienced poor after-sales support with some Samsung
830 SSD issues. Now I've found out that the 850 Pro also doesn't support
non-deterministic trim - so I can't use it with *any* Host Controllers with
LSI-based firmware (or whatever they are called now) - because trim support
will be completely disabled!!

Sure we all want V-NAND - but perhaps I should have waited a year or two
for Intel to catch up...

To quote from the bug report (referring to the crappy Samsung 840 EVO
firmware):
 I tried to contact Samsung support, but they answered that for the
support of this product, you should contact the reseller.
 In other words, they don't want to answer.

We are dealing with a drive that claims (during identification) to have a

Re: [gentoo-user] the new ssd, is it happy?

[Bob Wya]

Ahhh,

Quoting from the Intel 6 Series Chipset pdf...

 The PCH supports the Serial ATA Specification, Revision 3.0. The PCH
also supports
 several optional sections of the Serial ATA II: Extensions to Serial ATA
1.0 Specification,
 Revision 1.0 (AHCI support is required for some elements). Please see
Section 1.3 for
 details on SKU feature availability.

So your (newer) Intel Chipset supports the SATA-3 specification. That's
probably why you are seeing the issue and I'm not...

Re: [gentoo-user] Report: Experience with f2fs

[Bob Wya]

I would always recommend a secure erase of an SSD - if you want a fresh
start. That will mark all the NAND cells as clear of data. That will
benefit the longevity of your device / wear levelling.

I've been messing about with native exfat over the past few months. I found
this to be a pretty decent shared partition file system - for use with MS
Windows. The read performance will saturate a 3Gbit SATA link - but write
performance is only in the order of 100Mbytes/second.

Personally having been burned by btrfs I would not try one of these
experimental file systems again... That was the same sort of pattern as
your experience. I carefully followed the Arch Wiki (large partition size -
due to COW issues, etc.) - was using it on my home brew NAS running
OpenSUSE as root /. One day it just blew up and was really screwed for
recovery (I did manage to get the few small bits of data I needed with some
Googling) - as none of the btrfs tools for this actually work! Back to ext4
for root / - now running Arch on that box... Ironically the native ZFS port
has always been stable on that box (with a very large storage array)!

Just my $0.02!!

On 24 February 2015 at 00:46, Peter Humphrey pe...@prh.myzen.co.uk wrote:

 Some list members might be interested in how I've got on with f2fs
 (flash-friendly file system).

 According to genlop I first installed f2fs on my Atom mini-server box on
 1/11/14 (that's November, for the benefit of transpondians), but I'm
 pretty sure it must have been several months before that. I installed a
 SanDisk SDSSDP-064G-G25 in late February last year and my admittedly
 fallible memory says I changed to f2fs not many months after that, as
 soon as I discovered it.

 Until two or three weeks ago I had no problems at all. Then while doing
 a routine backup tar started complaining about files having been moved
 before it could copy them. It seems I had a copy of an /etc directory
 from somewhere (perhaps a previous installation) under /root and some
 files when listed showed question marks in all fields except their
 names. I couldn't delete them, so I re-created the root partition and
 restored from a backup.

 So far so good, but then I started getting strange errors last week. For
 instance, dovecot started throwing symbol-not-found errors. Finally,
 after remerging whatever packages failed for a few days,
 /var/log/messages suddenly appeared as a binary file again, and I'm
 pretty sure that bug's been fixed.

 Time to ditch f2fs, I thought, so I created all partitions as ext4 and
 restored the oldest backup I still had, then ran emerge -e world and
 resumed normal operations. I didn't zero out the partitions with dd;
 perhaps I should have.

 I'll watch what happens, but unless the SSD has failed after only a year
 I shouldn't have any problems.

 An interesting experience. Why should f2fs work faultlessly for several
 months, then suffer repeated failures with no clear pattern?

Re: [gentoo-user] the new ssd, is it happy?

[Bob Wya]

Super obvious question... but can you enable AHCI mode for your SATA
Controller - in the BIOS.

Are you using HP supplied SATA cables - because these may be sucky crap. If
so I would try replacing them - especially if they don't have latches on
the plugs.

I think this is the specification for your motherboard chipset:
http://www.intel.com/content/www/us/en/chipsets/mainstream-chipsets/h67-express-chipset.html
So you probably need the decent SATA 3G (6Gbit) cables to get the best
support for your SSD.

I've had some issues with 6Gbit SATA... Basically you are looking at really
high switching speeds - where connector quality makes a huge difference. It
might even be worth cleaning out your SATA connectors with isopropyl
alcohol (99%).

 Are these failed lines ok?

 The box itself is a bit older, a

 Hewlett-Packard HP Elite 7300 Series MT/2AB5, BIOS 7.12

 (I never found a BIOS update! btw ...)

 so maybe the chipset lacks features the SSD might be able to use.

 Everything works fine so far, I would just like to understand if things
 are OK with this new piece of hardware.

 additional:

 Device Model: Samsung SSD 850 EVO 500GB

 I did not find any firmware update online, do you agree?

Re: [gentoo-user] portage alternatives

[Bob Wya]

Michael,

I tried out paludis a few months ago. I do find Portage can be a bit slow.
So I thought great - a C++ version of Portage!

However cave does do much stricter checking and has much more verbose
output than emerge (way too much - like eix I guess). I really gave it my
best shot to migrate over fully - but had to bale after a couple of weeks
of trying to get one clean upgrade cycle. Speed wise - cave was slower than
emerge (with no backtracking). So regular day-to-day installs would be
quite slow (with the package tree being churned over multiple times).

I'm sure I'll give it another go at some point... Maybe I was simply using
it wrong... But boy it felt like it was for geeks who think Portage is way
too easy - give me something much harder!!

Robert

 paludis mostly because it seems to come from some gentoo-like enviroment
 and pkgsrc because of the nice thought to have the same pkg files for
 multiple OSes.

 Is anybody of you using one of them and can tell me about pros and cons?

Re: [gentoo-user] SMART drive test results, 2.0 for same drive as before.

[Bob Wya]

It would be far better to use Spinrite (like I mentioned before) - to allow
a really low level access to the drive. While Spinrite is running the HDD
will not be able to automatically relocate sectors. I've been blown away
how effective this piece of software is - even when run with (apparently)
very knackered Maxtor drives!! It was like they were brought back from the
dead...

 Your repeated dd action probably relocated some bad blocks.

 I would also run a long test overnight to see where and how it fails.  I
 recently had a drive which went sideways on me.  Running dd was successful
 in
 relocating some problematic sectors.  However, repeating the smart tests
 revealed that more and more sectors were going bad.  I recall a warning
 that a
 catastrophic drive failure was imminent, when reading the output of
 'smartctl
 -a'.

 Instead of dd'ing the whole drive, just dd the suspect sector and repeat
 the
 smart tests to see how things move around.  I concur with other posters
 that
 this drive should only be used for experimentation, rather than production
 or
 back ups.

As a double check I always like to test failing drives with Spinrite:

If that software can't recover/access any bits of the drive - it's pretty
