LVM Problem

Edol_1 — Fri, 07 Apr 2006 09:57:17 GMT

Hi all,
I have a L1000 and 73GB disk.I need to increment a /home, well the folowing command are execute:
umount /home
lvextend -L 15000 /dev/dsk/lvol5 - ok
extendfs /dev/rdsk/lvol5
when i mount this file system this message is displayed:
mount /dev/vg00/lvol5 /home
vxfs mount: /dev/vg00/lvol5 no such device
but this files (devices) exist in /dev/vg00
can you help me
my system is hpux 11.0

This step is wrong:

extendfs /dev/rdsk/lvol5

should be:
extendfs /dev/vg00/rlvol5

Why not using SAM?
Also the lvextend should go to
/dev/vg00/lvol5

instead of
/dev/dsk/lvol5

even the mount command is wrong:
root@egroup-/etc : mount -F vxfs /dev/vg00/rlvol5
mount: /dev/vg00/rlvol5 was either ignored or not found in /etc/fstab

should be without "r"
mount /dev/vg00/lvol5 /home

or just
mount /home

oooops sorry im write wrong (in forun) some commands.
This is the message on syslog:
Apr 7 10:24:25 egroup LVM[1417]: lvextend -L 16000 /dev/vg00/lvol5
Apr 7 10:24:25 egroup LVM[1417]: Volume Group configuration for /dev/vg00 has b
een saved in /etc/lvmconf/vg00.conf
when i run extendfs:
root@egroup-/etc : extendfs /dev/vg00/rlvol5
vxfs fsck: file system needs checking
vxfs fsck: cannot extend aggregate
vxfs extendfs: Invocation of the fsck program terminated abnormally.
The file system is marked bad. Run full fsck manually.
(e.g. fsck -F vxfs /dev/vg00/rlvol5)

and fsck

root@egroup-/etc : fsck -F vxfs /dev/vg00/rlvol5
file system is mountable - log replay is not required

root@egroup-/etc : fsck -F vxfs /dev/vg00/rlvol5
file system is mountable - log replay is not required
root@egroup-/etc : extendfs /dev/vg00/rlvol5
vxfs fsck: file system needs checking
vxfs fsck: cannot extend aggregate
vxfs extendfs: Invocation of the fsck program terminated abnormally.
The file system is marked bad. Run full fsck manually.
(e.g. fsck -F vxfs /dev/vg00/rlvol5)

I dont know why this happened.

What happens if you do:

# fsck -F vxfs -o full /dev/vg00/lvol5

Re: LVM Problem

Anil C. Sedha — Fri, 07 Apr 2006 11:20:40 GMT

Do the following

First as patrick mentioned, run the fsck command

Then

as mentioned earlier, run the extendfs command (increase by 1 Mb or so just for name sake) and then run extendfs.

Then run the mount command. However, make sure that you are running the commands using the right syntax as provided to you in earlier posts.

Edol,

You are not running the fsck command in "single user mode" with the "full" syntax.

You need to run the command as patrick mentioned

# fsck -F vxfs -o full /dev/vg00/lvol5

This will take care of the corruption issue. 99% chances are there is no issue here.

You can add a "-y" parameter to the command, so the yes-key will be pressed automatically.

looks good.
try to mount:

# mount /dev/vg00/lvol5 /home

if this fails, post

# ll /dev/vg00

Re: LVM Problem

Torsten. — Fri, 07 Apr 2006 13:20:37 GMT

first:

the group cannot read the device file

rlvol5

change this with

chmod g+r /dev/vg00/rlvol5

something went wrong while extending this LVOL.

can you recall your commands?

A fast way to recover will be to re-create this LVOL and restore a backup.

the
no such device
message is curious.

Re: LVM Problem

Edol_1 — Fri, 07 Apr 2006 13:37:38 GMT

this is last commands before extends volume (captured by strings .sh_history)
umount /home
lvextend -L 15000 /dev/vg00/lvol5
man extendfs
extendfs /dev/vg00/rlvol5
mount -a

fsck dont clean inodes, because i dont know
ok. I will recreate this volume.
Thanks for your help.

Re: LVM Problem

OldSchool — Fri, 07 Apr 2006 14:25:50 GMT

you did a lvextend on /dev/dsk/lvol5
you did extendfs on /dev/vg00/rlvol5

and ... depending upon the post above you sometimes reference /dev/vg00/lvol5 and sometimes /dev/vg00/rlvol5

from the directory listing, it appears that you did indeed run extendfs against rlvol5. Did you ever really extendfs lvol5?

Re: LVM Problem

Edol_1 — Fri, 07 Apr 2006 14:56:31 GMT

yes. For reason of time i will recreate a lvol and recovery (backup).

Thanks for your atention.
