HI
Did you checked the configuration in /etc/lvmconf/vgname

How you are takeing the ignite backup wheather it is vg00 backup or rather than another vg's backup

[Shrikant Lavhate]

Hi,

Ignite is exclusively meant for root VG backup i.e. system backup. Are you including any other VG? What command you are using???

[prasadb]

i am taking backup of entire vgoo, and using the command :

make_tape_recovery -x inc_entire=vg00 -AIv -a /dev/rmt/1mn

here, /dev/rmt/1mn is the path of tape..

And i did not find the file vhname at etc/lvmconf/

[prasadb]

please help me in this regard..

[Steven E. Protter]

Shalom,

Confirm every entry in /etc/fstab

If the path is not there, comment it out. Do check and see why its there though.

You might have lost a disk and need to restore a previous Ignite backup.

Hello Steven,

i have Confirmed every entry in /etc/fstab
the /dev/vgrp05/Backup was not found there..

kindly help

Check your /etc/lvmtab file for this entry.

# strings /etc/lvmtab | grep Backup

If it exists there, that could be your problem.

Also do a 'vgdisplay -v vgrp05' and verify that you don't have a logical volume named Backup.

If you see the entry in /etc/lvmtab, and you don't have an LV by that name, then you can try recreating your /etc/lvmtab file by doing:

# mv /etc/lvmtab /etc/lvmtab.bad
# vgscan -a

[prasadb]

hello patric, thanx for the reply

the o/p of strings /etc/lvmtab | grep Backup is null, it means there is no partition called Backup.

vgdisplay -v vgrp05

# vgdisplay -v vgrp05
the o/p of this command is :

vgdisplay: Volume group "/dev/vgrp05" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vgrp05".

There is no entry in /etc/lvmtab of vgrp05

[Patrick Wallek]

OK, now we're getting somewhere.

You should now check and see if you have a directory in /dev called vgrp05.

# ll -d /dev/vgrp05

If it is there, check the contents:

# ll /dev/vgrp05

Now if you are sure that you don't have a VG called vgrp05, but the directory exists in /dev, then it should be safe to remove.

# rm -r /dev/vgrp05

Hi,
mount filesystem information will keep in /etc/mnttab, please run cat /etc/mnttab to see which volume group that mount to /Backup

[prasadb]

output of # more /etc/mnttab is as below :
