unable to extend LV

Randy_9 — Wed, 16 Oct 2002 15:07:46 GMT

I get the following error message when trying to extend an LV:

The command used to resize a VxFS f/s has failed.
vxfs fsadm: /var/adm/sw is not the root inode of a vxfs file system.

The LV as listed in /etc/fstab:
/dev/vg00/var_adm_sw /var/adm/sw vxfs delaylog 0 2

Show's up as a LV in SAM (from
which I tried to extend it)?

Thanks,

Randy

I may be wrong, but as per the error message it seems your /var/adm/sw filesystem is not mounted at present. Can you please post the command you had given?

Hi

What does the server think is mounted

grep /var/adm/sw /etc/mnttab

mount -p
shows which fs's are currently mounted,

mount -a
will mount all in /etc/fstab,

what is your commandline:

lvextend -L new_MB_size /dev/vg00/var/adm/sw

or are you doing and

extendfs -F vxfs /var/adm/sw

?

Later,
Bill

Are you using fsadm to extend it (online perhaps) ? If that's the case this error usually means you've issue a wrong syntax (for example not using raw device path), or the FS that you're extending is not mounted.

All,

I was using SAM to extend it. I had stopped "swagentd" prior to and umounted it manually first. When mounted the device name is the same in both /etc/fstab and etc/mnttab. Strange thing is now:
SAM is showing it as being extended (to 700MB) while
a "bdf -l" shows it at 400MB
when mounted.
Now what?

Points assigned.

Thanks,

Randy

Forget SAM for a moment. I've had "ugly" experience with it which I would not want to talk about it here. Check ..
# vgdisplay -v vg00|more
=> Does the "var_adm_sw" LV shows the new size that you have extended to ?
# bdf -l
=> Again run this, does the FS size match up with that of LV size ?
If not manually umount it again and run extendfs on it.
# umount /var/adm/sw
# extendfs -F vxfs /dev/vg00/rvar_adm_sw
# mount -a
# bdf -l
Does it shows up fine now ?

What about the lvdisplay output? Is it showing the new size? If you 've not patched the system properly, then you may experience these type of errors.

# lvdisplay -v /dev/vg00/var_adm_sw

Randy

can you run it from the command line like

lvextend -L (size)/dev/vg00/rvar_adm_sw

and then fsadm /var/adm/sw

S.K. Chan,

The vgdisplay showed it at 700MB, but "bdf -l" did not. I umounted it and was able to extend it via the command line. SAM... ughhh!

S.K. and Manoj,

Do I still need to run "fsadm", I have already remounted it and "bdf -l" is now showing the correct size.

Thanks all, points assigned!

No, all you do is lvextended your LV with the filesystem umounted, there is no need for "fsadm" command at all. The "fsadm" typically deal with MOUNTED filesystem. For example ..
- increasing mounted FS on-the-fly
- fragmentation report
- defragmentation
