ignite and vg00

[Matrah]

Hi ,

I have the message : information in "/etc/lvmtab" differs from that in "/etc/lvmpvg".
VG "/dev/vg00" is not defined in file "/etc/lvmtab".
And, when i excecute this command : srings /etc/lvmtab | grep vg , i don't see any information about the vg00.


Thanks

Hi,
Can you explain me further. As far as i know the /etc/lvmpvg will not give any problem to you.

Last day i restored an Ignite backup and it found working fine.

Matrah,
Have you tried re-creating the lvmtab?
mv /etc/lvmtab /etc/lvmtab.old
vgscan -v
strings /etc/lvmtab

This will create a new lvmtab file. When you do a strings on the lvmtab, does your vg00 information show?

Regards,
Eric

vgscan -v doesn't do anything :((
here the message : lvdisplay -v /dev/vg00/lvol3 | more
lvdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
lvdisplay: Cannot display logical volume "/dev/vg00/lvol3".

Hi,

Try this.
copy /etc/lvmtab as /etc/lvmtab.save
Run insf -e
than run vgscan -v

Goodluck,

Just for clarification, I think Uday is suggesting that you "mv" to lvmtab.save and not "cp".

some news.....
look at my /etc/lvmtab ....is it correct that i see only /dev/ ? whereis the vg00 ?

/dev/
|h;2
/dev/dsk/c3t4d0
/dev/dsk/c3t5d0
/dev/dsk/c4t4d0
/dev/dsk/c4t5d0

[erics_1]

If you cd /dev, do you see a directory for vg00? If not, try:
mkdir /dev/vg00

From here, I would restore from backup everything at /dev/vg00.

Afterwards, move the lvmtab again and run vgscan -v.

Hope this helps!

Hi,

lvmpvg is only for volume groups that have physical volume groups defined. If vg00 doesn't have PVGs then it won't show in lvmpvg.

It is correct to use "strings /etc/lvmtab". You should see the VGs and all disks assigned to each VG. If you don't see vg00 then you need to follow Eric's suggestion.

As an example, here's what I got when I ran vgscan -v on a test system (after mv /etc/lvmtab /etc/lvmtab.old):

root:/etc # vgscan -v
Creating "/etc/lvmtab".
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00".
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg28".
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg02".
Couldn't stat physical volume "/dev/dsk/c5t2d0":

Note the message about c5t2d0 which is the dvdrom drive and can be ignored.

Hello ,

Sorry, but none of your solution resolv my problem ....

No more idea ?

[Frederic Sevestre]

Hi,

Did the /etc/lvmpvg contains the list of the vg00 disks ?
You should try to move both the lvmtab and the lvmpvg and run vgscan to recreate the lvmtab.

# more /etc/vmpvg

[Darrell Allen]

Perhaps you could post the steps you have taken so far (particularly in relation to vgscan).

[Matrah]

the probleme is OK..
In fact, the file /dev/slvmvg had the same minor and major number than /dev/vg00/group
