[linux-lvm] Problems with 0.9.1b7 and 2.2.20-2

[linux-lvm] Problems with 0.9.1b7 and 2.2.20-2

[Rasmus Andersen]

Hi.

I have built a 2.2.20-2 kernel with kiobuf-2.2.18pre24-B.tar.gz
applied and patched with the patch lvm_0.9.1_beta7 created.

I have begun to get the following in my /var/log/messages in
conjunction with various programs (tar, cp) failing:

Jun  4 21:55:05 firewall kernel: attempt to access beyond end of device 
Jun  4 21:55:05 firewall kernel: 08:01: rw=0, want=530424, limit=410608 
Jun  4 21:55:05 firewall kernel: dev 3a:03 blksize=1024 blocknr=622593 sector=1060840 size=4096 count=1 
Jun  4 21:55:05 firewall kernel: EXT2-fs error (device lvm(58,3)): read_inode_bitmap: Cannot read inode bitmap - block_group = 19, inode_bitmap = 622593 
Jun  4 21:55:05 firewall kernel: EXT2-fs error (device lvm(58,3)): ext2_check_inodes_bitmap: Wrong free inodes count in super block, stored = 307461, counted = 291461 


I can do a 'dd if=/dev/<diskX> of=/dev/null' for the disks that are
part of the volume group without problems but if I do it for /dev/vg1/
lvol4, I get the error above (without the EXT2-part).

I am now trying to get whatever data I can off the FS and would like
1) helpful suggestions, and 2) to provide whatever feedback I can
before I have to reclaim the disk space. Probably for something
non-LVM for the moment.

Please mail me for additional information. I am rather new to LVM
and have little clue as to what information you might find useful.

This sounds like a well known ext2 problem.
Did you run fsck successfully? And if so, didn't it work again?

Did you *really* run "dd if=/dev/vg1/lvol4 of=/dev/null" and got that error
in the log? Never have seen that before.

Uhm. Known problem? Could you elaborate a bit? I have not seen it
before and would like to know if it is something I will encounter
regularily using ext2 and LVM.

I have run e2fsck a number of times now, and while I do not get
the kernel log message after the reboot (se below) fsck complain
and fix stuff every time in lost+found which contain a lot of
junk I cannot delete manually either.

I will try to reproduce. But trying to get as much as the (used) 
filesystem with off the disk with tar resulted in a kernel panic
(this was just after my last mail):

panic: brw_page: page not locked for IO

This was put after a couple of lines of 

Jun  5 10:04:35 firewall kernel: attempt to access beyond end of device 
Jun  5 10:04:35 firewall kernel: 08:01: rw=0, want=530420, limit=410608 
Jun  5 10:04:35 firewall kernel: dev 3a:03 blksize=1024 blocknr=622592 sector=1060832 size=4096 count=1 

on the console.

Forgot to state that before the panic->reboot fsck could not complete.
It ran up against a short read with the kernel log entry as reported.
This was (of course) on /dev/vg1/lvol4, not mounted.

To finish this off: I cannot reproduce it after my reboot.

I was refering to ext2 consistency problems in older kernels which have been
fixed in the meantime. You need to have recent ext2 tool as well.

No, you shouldn't in case you have recent ext2 software.

Oops. Bad luck then.
In case you are able again, please provide the configuration information and
log here.
