vgdisplay - invalid lv in extent map

Ratzie — Wed, 22 Mar 2006 14:39:36 GMT

We just recently rebuilt a RH ES3 to RH 4.
Everything is working fine, database is working on these LV's, things are getting written too, except for vgdisplay.

Now everything is under /dev/mapper instead of /dev/vg01
But, from further reading this should not be an issue.

I believe this is also causing an issue when we try to create a lv for snap shot backup.

Error:
[root@server ~]# vgdisplay

Shalom,

How about:

vgdisplay /dev/mapper/vg01

or

vgdisplay -v /dev/mapper/vg01

I'm just feeling my way around with lvm on Linux but I'm thinking my command should work.

All poop out.

[root@server ~]# vgdisplay /dev/mapper/vg01
Invalid volume group name: mapper/vg01
[root@server ~]# vgdisplay -v /dev/mapper/vg01
Using volume group(s) on command line
Invalid volume group name: mapper/vg01
[root@server ~]# vgdisplay /dev/mapper/vg01-lvdb1

Run vgcfgbackup -f /etc/lvm/backup/vg01-lvm.bak vg01

Then run

vgcfgrestore vg01

To try to fix the LVM database configuration.

Will this harm the data on the logical volume?

Any precautions?

Always have a good backup before any changes related to disk. The command should not generate any problems, at maximum should fail.

lvm on linux is more or less the same as on HP-UX.

On HP-UX I would try vgscan -v.
Ypu may even need vgimport.
Check the man pages...

I can not run vgcfgbackup or any vg command. I have opened up a trouble with RedHat.
