I might add, on a older rig I tried that command once. I ran rm -rfv /* and it didn't erase everything like I thought it would. I figured the command would be loaded in ram and would run until the end of the / structure. It didn't. I can't recall how far it got now but I think it was in the /proc directory. I figure it deleted the process and sort of forgot to finish. It's been a while since I did that tho. Details are fuzzy. # rm -rfv / rm: it is dangerous to operate recursively on ‘/’ rm: use --no-preserve-root to override this failsafe # rm -rfv --no-preserve-root / ** deletes lots of stuff** ** cannot delete in /proc ** ** cannot delete in /sys ** ** deletes more stuff ** ** finshed with status 0 ** System broken :-) Don't worry, it was only a virtual machine. signature.asc Description: OpenPGP digital signature

I see ... so installing the MBR code in the /dev/md0 block device is further down the disk than where BIOS is looking for it and that's why it errors out? That would be my guess. Maybe someone more knowledgeable on how mdadm writes stuff on the disk can jump in and provide additional info. But I'm pretty sure, if you install grub in md0, it's not in that place on the disk where the bios is actually looking for. It seems to me then that I *have* to create normal partitions on /dev/sda /dev/sdb, or I would need a different boot drive. Is there another way to overcome this problem. Maybe create two mds. md1 (sda1, sdb1) is a small boot partition which contains stage2+, the kernel and the initramfs. And md2 (sda2, sdb2) which acts as another block device with partition table, etc... In this setup you could install grub in the mbr of sda and sdb (grub-install /dev/sda...)

And these packages do not have mail use-flag, because their maintainers apparently expect standard *nix mailer (/usr/bin/sendmail) exists on the system... So now I have stable system, updated to the latest level, where a lot of things suddenly do not work. This should *never* happen! If it was some package's dep that caused it, it's clear this change was premature... I think is a bug in the packages. In my system the only package that pulls vitual/mta (and therefore ssmtp) is vixie-cron. That is strange. I have sys-process/vixie-cron-4.1-r12 and yet revdep-rebuild does not want to pull virtual/mta. But It should, as cron can be configured to send emails too. Read my last mail; they changed the RDEPEND for the cron eclass. As I wrote: there are *many* packages that expect standard *nix mailer exists! If it does not, a lot of packages must be fixed to include mailer as dependency. The devs disagree. I think I'm with them; the packages in question actually work, it just happens that they can't send mails anymore. If you need/want them to send mails, install an MTA. Just can't send mails. So if mdadm detects failed drive in raid1 and I do not get mail about it, I will discover it at least when the 2nd drive fails. That's a relief...

So I'd rather trade off a bit less speed on the new machine, versus compatability issues. I also prefer to be able to scp the VM disk images to the backup machine, rather than having to do a separate install on each machine. You can use march=native on your gentoo hosts, that's no problem, as long as you don't use it on your guests. That's the hole idea of VMs: being able to move the virtual machine to another machine, that might be completely different in terms of hardware. The goal is, to be machine independent. In your case, I'd say it would make sense to chose core2duo as qemu host cpu.

Alternatively, you could run rsyncd on the client, which avoids the need for the server to be able to run an SSH session. I think the sacrifice is that with the backuppc method, if someone breaks into the backup server they will have read(/write) access to the clients. The method I'm describing requires more management if you have a lot of machines, but it doesn't have the aforementioned vulnerability. The rsyncd option is interesting. If you don't want to restore directly onto the client, there are no SSH keys involved at all? Not even then, the server talks to the client in the same way for restores as it does for backups, so it would still use rsyncd if you wanted it to. Hmmm, now that I think about it, I guess the server accessing the client via rsyncd still provides the server with root read/write access to the client just like SSH keys. I don't think it too unreasonable to assume that a machine with no ports exposed to the Internet will not be compromised from the Internet. Whereas a push approach requires that the server have open ports. Agreed, but this requires that the backup server is local to the admin which may not be possible. openvpn requires open ports of course. There's also the possibility of a local break-in That' how we do it. The backuppc server is in our local lan, and only accessible from local lan. It pulls backups from all our machines in offsite data centers. To compromise our backuppc machine one would have to physically break into our companies building. But if somebody has physical access to the machine on which you store your backups, you're screwed, no matter if you use push or pull backup :) signature.asc Description: OpenPGP digital signature

I have not used pulseaudio at all, but with gnome 3.8 I guess it must be there, but when I try to play a sound using either mplayer from the console which works fine withalsa, or even aplay, I get no sound unless I change the /etc/pulse/client.conf to spawn=no . Unless you have a very specific setup, you should not need to touch the files under /etc/pulse. Also, are you trying to run the system-wide PulseAudio service? Because that's basically wrong: http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/WhatIsWrongWithSystemWide Anyway to fix this? If you are running PA as a normal user (as you should), then perhaps the per-application volume for MPlayer is muted. While playing something with MPlayer, go to Settings - Sound, then select the Applications tab, and there should be a volume slider for all the applications using audio. Just adjust as necessary. I got no sound when pa was run as a user. I am running these apps from the console -- apps such as aplay or anything which uses alsa. So I can't adjust any volumes under gnome, etc. Also, from the console you can use pactl. To play a sample sound there, do: pactl play-sample 0 pactl play-sample 1 It should work. You can also set the volume from here: pactl set-sink-volume 0 100% 0 is usually the master volume. Check out man pactl. Well, in either system or user mode, root can play sound whereas a regular user gets silent, but without pulseaudio -- spawn=no, then a regular user can play sound. Does this give a clue? Not really; as I said, the PA documentation clearly says that if you use system mode You are on your own. You need to know you way around, be able to write init scripts, dbus policies, to fix up device permissions, and unix users, you need to pass around security cookies and more. I haven't ever used system-wide PA. I think of the following; try to delete both /root/.pulse and $HOME/.pulse, and rebooting (probably a logout/login should suffice, but you never know). Another thing: if you installed PA since GNOME 3.8 needs it, why are you using it without GNOME? If you use GNOME, the session manager will automatically start PA as a user for you, and everything should work. If you are not running GNOME, why do you run PA? If you are at the console without X running, just don't use PA. Use mplayer -ao alsa or whatever. Or do you want to run several audio apps in the console? I want to run apps from the console, but to start gnome when I need it. Then do that. When you start GNOME, it will start PA automatically: you don't need to do anything. Don't try to start PA yourself; it's DBus activated. I am running pa as a user and things are still not working, except for the root user who can play sounds. I repeat: you don't need to run PA. GNOME will start it for you. But will that workif I have spawn=no in my /etc/pulse/client.conf which I have to have for regular apps to work from theconsole? Or is there some other way to make this happen? I don't understand the question. If you don't run PA by yourself, then it will be started only when using GNOME. And if you are using GNOME, you can use the nice sound settings dialog to get your sound. If you don't start GNOME, then PA will not be started. If you don't have sound in your console even without PA running, then is for some issue completely unrelated to PA. PA should not be started if you only log in through the console. Unless you are still running it system-wide, which is basically unsupported. OK, we will see what happens, so I have set spawn=no which should work to prevent pa except in gnome, so hopefully that should work. Thanks for clarifying this for me. -- Your life is like a penny.

Correct, in almost every case where I set up a VM Host, I use LVM to manage the disks that the guests will get.

I've masked current one app-text/poppler-0.22.2-r2 but looking at the web-page this is not even stable poppler-0.22.3 is masked all across the previous version are all removed. All the packages that I recently try to roll back are gone, in most cases only one is available so there is no option to roll back. Am I missing something? The version of poppler that you have masked ( 0.22.2-r2 ) is stable. So it's not a portage screw up, the problem is more that you are trying to install outdated software.

Rgds, -- Well, it's a KVM virtual machine. And I'm *currently running* it with -march=core2 on 64bit, but that isn't very safe because it may be migrated any time in case the host fails. I guess it would be best to use generic x86_64? Or perhaps switch to 32bit because it's just 2 GB of RAM and it can't be bumped up any further (top end config). Some search reveals that it's an upstream bug where the CPU is detected as pentium m which happens to be 32 bit. I use this on 64bit VMs, but maybe nocona is better?

Don't know what you guys do for rebooting a headless server blindly like this,
nor if it would work for the udev/NIC situation. But fwiw, what I've always
done for new kernels is:
mingdao@server ~ $ egrep -v (^#|^ *$) /etc/lilo.conf
compact
lba32
default = Gentoo-def
boot = /dev/md0
raid-extra-boot = mbr-only
map = /boot/.map
install = /boot/boot-menu.b # Note that for lilo-22.5.5 or later you
# do not need boot-{text,menu,bmp}.b in
# /boot, as they are linked into the lilo
# binary.
menu-scheme=Wb
prompt
timeout=50
append=panic=10 nomce dolvm domdadm rootfstype=xfs
image = /boot/vmlinuz
root = /dev/md0
label = Gentoo
read-only # Partitions should be mounted read-only for checking
image = /boot/vmlinuz.old
root = /dev/md0
label = Gentoo-def
read-only # Partitions should be mounted read-only for checking
Then issue lilo -R Gentoo or whatever the label of your new kernel, and if
it boots, you're okay. If not, after 10 seconds of panic, it automatically
reboots back into the default kernel and you can check logs to see what you've
broken. (panic=10 append statement and default = Gentoo-def) After you know
the new kernel works, comment the default line. (NB: You can name them
differently, etc. It just helps to know before you reboot that if you panic,
the machine will boot back into the known, good, kernel.)
Granted, this might not help with the udev/NIC situation, but it's saved me
from a few PEBKAC situations, as well as new kernel changes I'd not learned
until the reboot.
I have something similar with grub (with grub set default, savedefault,
fallback). Also most machines have some sort of rescue access with like
ipmi serial over lan or a eric card (kvm). But some remote machines
don't and rebooting them is always a thrill :) I mean, there are rescue
systems that can be invoked via bootp, but you are blind while rebooting.

Hi Michael, If you have the time, maybe you can post your GrUB setup and a short HOW-TO do this somewhere. I've often mentioned doing it with LiLO in #gentoo on Freenode and always get flamed by GrUB fanbois, but to date none has been able to produce how to actually do it with GrUB. Since Gentoo now recommends GrUB rather by default, it might be nice for folks to know how to use this. Thanks, Bruce This actually is pretty straight forward :) Here's a small sample config for grub 0.97. But I'm pretty sure that this will work with grub2 too. ### grub.conf ### # set default boot entry to prev. saved state: default saved # seq. order of boot entries fallback 1 2 3 # here are the kernels title gentoo 0 kernel /kernel panic=15 savedefault fallback title gentoo 1 kernel /kernel panic=15 savedefault fallback title gentoo 2 kernel /kernel panic=15 savedefault fallback title gentoo 3 kernel /kernel panic=15 savedefault fallback ### end grub.conf ### what I now do is this: set the default boot entry to zero with % grub-set-default 0 On the next reboot this happens: grub reads the default: 0 grub boots entry 0 and sets the default entry to 1 (or 2 according to the fallback line in grub.conf) If the systems panics, it reboots. But this time grub will load entry 1 as it is the default now (and so on, and so on). If the systems booted successfully and you verified that it actually booted the new kernel, you now have to set grub default to 0 with grub-set-default. You can to this with a small script in /etc/local.d/local.start Maybe send the admin a warning that the system has not booted with the default kernel. That's up to you :) HTH

Re: [gentoo-user] Is 'MAKEOPTS=--jobs --load-average=5' silly?
Am 25.03.2013 21:57, schrieb gottl...@nyu.edu: For a long time I have had in make.conf EMERGE_DEFAULT_OPTS=--ask --deep --tree --verbose --jobs --load-average=5 MAKEOPTS=--jobs --load-average=5 (for previous processors the 5 was 3). It seems that this configuration fails for several packages (or tickles bugs in their ebuilds/Makefiles). Lately whenever a build fails I change to MAKEOPTS=--jobs=1 and this very often fixes the problem. It is not clear that any time saved by having jobs=5 compensates for having to redo builds. So my question is do people 1. keep jobs=1 in MAKEOPTS 2. have jobs=n in MAKEOPTS but degrade on error as I do 3. have jobs=n and file bugs when it fails. thanks, allan PS I do not change EMERGE_DEFAULT_OPTS This is what I use: EMERGE_DEFAULT_OPTS=--jobs=2 --load-average=6 I havent't had any failed builds that were related to the --jobs option. The only exception is when rebuilding my kernel modules. I have to build spl first, then zfs-kmod. But that's because zfs-kmod requires a complete built spl.

As a dependency of virtual-sources, which is probably pulled in by kmod. Adding --tree would have told you for sure. You may get away with adding gentoo-sources to package.provided. Thanks, this works (never heard of this file before). But there is one small problem: no wildcards are allowed, so whenever new sorces come I'll have to edit package.provided again, and again No, that's not true. Here's the quote from the man page: Portage will not attempt to update a package that is listed here unless another package explicitly requires a version that is newer than what has been listed. Dependencies that are satisfied by package.provided entries may cause installed packages satisfying equivalent dependencies to be removed by emerge(1) --depclean actions (see the ACTIONS section of the emerge(1) man page for more information).

Re: [gentoo-user] A question concerning graphics...
Am 10.03.2013 09:54, schrieb Chris Walters: Hello Everyone, I have a couple of questions concerning what graphic drivers you use. Does anyone use the proprietary ATI drivers, or have used them? Would you recommend them? I just recently started using the ati-drivers package, but I don't really notice a difference - yes it does say the frame rate is much higher, but I am not sure it is worth losing my framebuffer over them. Technically, I lost my frame buffer because I am using an initramfs (initrd) because I have an encrypted root file system, and a separate non-encrypted usr partition. I still have not been able to figure out how to get either uvesafb or vesafb working through the initramfs. They will both load fine, before my initrd starts, then they seem to disappear. In case you're wondering, before I changed to the proprietary ati drivers, I was using the kernel framebuffer for my video card(s). Two Radeon HD 5000 series cards. I did have to insert the proper ucode into my kernel, but it worked. Chris I use the ati-drivers package, and I'd say there are pretty solid now.

In the best event, that should slightly decrease apaches overall memory footprint.

Re: [gentoo-user] [PATCH] Linus breaks virtualbox-modules
2013/2/20 walt w41...@gmail.com Now that kernel 3.8.0 is officially released, 'tis the season for Linus to start breaking all of the third-party kernel modules he can, and virtualbox- modules is the first (nvidia.ko and other kernel modules to follow, probably ;) Virtualbox-modules fails to build against today's kernel.git update from Linus, with an error message that MAX_PRIO is undefined in thread2-r0drv-linux.c. The fix is happily very simple because he moved the definition of MAX_PRIO into linux/init_task.h, so all you need to do is to add that include near the top of thread2-r0drv-linux.c. r8168 breaks too, but I haven't looked into it yet.
