[linux-lvm] LVM problems

[Kelly Harding]

[-- Attachment #1: Type: text/plain, Size: 611 bytes --]

Hi,

I've just brought my Debian Linux box back up after a power failure and 
now my LVM set up seems to be non-functional.

I'm not very clued up on LVM tbh, but it has worked so far fine for ages.

I get the following error if I try  to run 'vgchange -a y 3diskvolume:

device-mapper ioctl cmd 11 failed: Invalid argument
   _deps: task run failed for (254:0)
   Failed to add device (254:0) to dtree
   1 logical volume(s) in volume group "3diskvolume" now active

It obviously won't mount after that as mount tells me it can't find the 
superblock etc.

any ideas? is one of the discs dead?

Thanks,

Kelly

Hi again,

Forgot to add details:

PC: dual PII/350mhz (p/pro overdrive), 512mb ram, SCSI LVD 80mb/s.

The VG is across 3 36gb scsi drives attached to an adaptect 2940U2W card.

I'm running kernel version 2.4.27 (2.6 doesn't seem to like this system).

I noticed from the dmesg output the following:

device-mapper: one of name or uuid must be supplied, cmd(11)

This appears when the previously mentioned command is run.

I've no idea what this means or if it isa case of a re-install of the 
base system might fix this? maybe something with the
base system has gone a bit fubar?

any help or advice on this would be greatly appreciated.

If it comes ot it that I lose the data and have to format and star the 
LVM VG over again it won't be ideal but it won't
be losing anything vital either (just video files, etc).

Kelly

Recently I also suffered problems with LVM(2)

These are very basic things I presume U might have already done but just in
case if not ...

imho pl boot with rescue disk (or mode)
As a precaution select read-only mount of file system
if required chroot to /mnt/sysimage
# mount  ! look for lvm things specifically a word - mapper
# pvdisplay
# vgdisplay
# lvdisplay
# pvscan
# vgscan
# lvscan

thiese will tell status of lvm things
 Then check /etc/fstab (carefully)

U may then "very very carefully" use e2fsck or fsck [{("after dismounting
the volumes")}] as you may you deem fit.
"very very carefully"  means, as a minimum, first read both manpages, try
these commands in read-only mode + do not modify anything + verbose.

### use vgck with caution and also checkout /etc/lvm/lvm.conf

U may try in init 1 mode also but more caution requested.

good luck & Pl post if U get it right this way or anyway.

This development version of LVM2 requires a 2.6 kernel - it relies
on patches added to 2.6 upstream about a year ago.

Either upgrade to a 2.6 kernel or downgrade your lvm2 & device-mapper 
packages.

It would be straightforward to backport the changes to 2.4 but
nobody's done it yet.  Patches welcome!

[linux-lvm]LVM Problems

[David Rohrer]

[-- Attachment #1: Type: text/plain, Size: 1744 bytes --]

I had set up a Red Hat 9.0 Box with no xwindows on it just mainly the basic install.
The /boot, / , and swap are all on HDA....then on HDG and HDH I set up a LVM during the install.

After I filled the drives in the LVM with data I tried to add to more drives to it they were HDC and HDD.
 I'm not the best at this, so I was reading how on the interent...I first tried to just do vgextend and it would error, so i done a pvcreate for each drive and then done a vgextend then I rebooted, I never did a change. so now when it boots it errors out trying to mount the volume and I would have to go into maintenance and edit the fstab and comment out the volume so it will boot

This is what I get when I do a pvscan:
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hdg1"  is associated to unknown VG "Volume00" (run vgscan)
pvscan -- inactive PV "/dev/hdh1"  is associated to unknown VG "Volume00" (run vgscan)
pvscan -- total: 2 [38.03 GB] / in use: 2 [38.03 GB] / in no VG: 0 [0]

And this is what I get from a vgscan:
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hdg1"  is associated to unknown VG "Volume00" (run vgscan)
pvscan -- inactive PV "/dev/hdh1"  is associated to unknown VG "Volume00" (run vgscan)
pvscan -- total: 2 [38.03 GB] / in use: 2 [38.03 GB] / in no VG: 0 [0]


I can send you a vgscan -d if you like but it is quite long, I have data on the volume and would like to fix it, is there a way to fallback to how it was before I tried to add the other 2 hard drives? And if so how do I add the new ones properly?

Thank You

Ahhh..that explains a lot. My sincere apologies. I was not aware that it was
fixed in CVS. I'd never seen anyone be referenced to that. Thanks for info.

Why in the hell is this NOT in the source tree by default. This has really
got be boggled. I've seen tons of others have this proble, I've had this
problem, and still it doesn't seem to get itself into the tree. Is this
because it is a temporary problem or something?

It *is* in the source tree by default.  It is in the CVS.  It is not in
LVM 0.9.1 Beta7 because LVM 0.9.1 Beta7 was released before linux 2.4.4,
which is when the problem surfaced.  We have not had a release since then,
so it is not in the latest release.

You can now grab the patch and apply it to beta7, which fixes the problem,
or you can use the CVS repository.  I really don't know what else you expect
us to do.

Actually getting the up-to-date lvm in the kernel would be nice.  Last time
I asked 2.4.<x>-ac<y> was about half way there.  What is happening?  Have the cvs
procedures been modified to enable producing Linus friendly patches?  When
can we expect a kernel with a current lvm?

Please read the above as just as a request for info.  LVM is working ok here.
Its just a bit of a pita to have to patch everything every time I rebuild a
tree...

Ed,
Linus *never* answered when we send hom patches even though I've send them
multiple times.
We are working together with Alan Cox since weeks to get his -ac tree updated.

Once he has it in he will push it to Linus.
Hopefully small changes in the future will make it in easier (sigh).

and linus has said many many times on l-k: he gets loads and loads of
mail, he reads it with his finger on the D key, if you hear nothing
from him, keep sending.

also, you can almost take it as given that he won't look at anything
but emails that contain an inline diff (unified format) that tackles
one specific problem/update. URL or mime attachment -> deleted.

again, just like Ed, i have to say that i'm not bitching.. i think
LVM is just about the best thing since sliced bread - truly my
favourite linux kernel feature. so all i want to point out is that
LVM'd be just that -> <- much better if you guys kept LVM closely
in-sync with Linus. and best of all, for everyone ultimately, if
you'd ditch your private CVS tree altogether and just sync through
Linus very regularly..

(we don't care if sometimes you introduce bugs by sending patches
very frequently to Linus, cause we'll know that you just as regularly
send fixes.  but don't accumulate bug-fixes over many months in a cvs
tree and sit on them.)

but i do love LVM.

Yes, we kept sending (sigh).
Thanks to Alan, we'll hopefully make it soon into vanilla.

That's exactly what we want to conform to.
It just takes a hole lot of time (several weeks now) to feed it into -ac.

And believe me, Alan is *very* helpful here but he can't work on just LVM
integration for sure.

Once we've got -ac updated, we'll try setting up a cron job to feed in the
small patches we are going to send to Alan/Linus ;-))

Please calm down folks!

If you had followed the thread here you had seen that people recommended
to wait with 1.0 till vanilla is updated.

We plan to release 1.0 on Friday when at least -ac will hopefully be up to date.

[linux-lvm] LVM problems

[Tobias Hahn]

Hi!

I have serious trouble trying to get LVM to work again since I upgraded my lvm-tools to 0.9beta6. I cannot access my vg (and needless to say, almost all of my system is on that vg :-( ). The problem is that the kernel complains about an unsupported ioctl. I looked up this problem in lvm-related mailinglists and figured out that this is a version mismatch between kernel lvm and user lvm. At that point I was using kernel 2.4.3. According to the mailing list, the problem should be fixed in kernel 2.4.4. However, kernel 2.4.5 (downloaded from ftp.kernel.org) still contains 0.9beta2. So I downloaded the lvm-source from ftp.sistina.com (both beta6 and beta7) and tried to patch kernel 2.4.5 following the instructions in PATCHES/README. The patched kernel, however, does not link any longer.

All I'm asking for is a way to get my data back - either by telling me how lvm can be convinced to run or by just getting that stuff off lvm and removing lvm from my system. It would be very nice if someone could at least acknowledge receipt of this problem report, my last mail seems to have vanished out in the void.

Thanx everyone for reading this mail!

Regards, Tobias Hahn

It is known problem and should be fixed in future releases.
For now use attached patch.

I've found it in archives of this maillist when I've faced simular problem.

But this message is only a warning, and not a real source of problems.
If you are having problems, it is from something else.  If you were using
the beta2 tools or earlier, there is a chance your VGDA is slightly broken
(UUID problems).  Please search the mailing list about this for instructions
on how to fix.

There are some LVM fixes in the -ac kernel patch, but none in the Linus
tree yet (sigh).

I could have sworn this problem was fixed already, but maybe only in CVS?
Time for a new patch release I guess.  As someone else already mentioned,
simply change get_hardblocksize to get_hardsect_size() in lvm.c.

Cheers, Andreas

I dropped a patch on the FTP site:
ftp://ftp.sistina.com/pub/LVM/0.9.1_beta/lvm_0.9.1_beta7-get_hardblocksize.patch

apply this to your LVM source tree and regenerate the kernel patch.
