I had originally posted this issue over on the Fedora Forums but it
really belongs here.
---------------
I have an LVM backup stored in a file that now I would like to list
using vgcfgrestore.
================================================
Under LVM1 all I needed was:
# vgcfgrestore -ll -f /tmp/.mgwork/Volume00.conf
vgcfgrestore -- this is a backup of volume group "Volume00"

================================================
Under LVM2 when I try this I get this output:
# vgcfgrestore -ll -f /tmp/.mgwork/VolGroup00
Please specify a *single* volume group to restore.
# vgcfgrestore -ll -f /tmp/.mgwork/VolGroup00 -n VolGroup00
Please specify a *single* volume group to restore.
# vgcfgrestore -ll -f /tmp/.mgwork/VolGroup00 VolGroup00
File: /etc/lvm/archive/VolGroup00_00000.vg
VG name: VolGroup00
Description: Created *before* executing 'vgdisplay
--ignorelockingfailure -v VolGroup00'
Backup Time: Sat Oct 28 13:29:00 2006
File: /etc/lvm/backup/VolGroup00
VG name: VolGroup00
Description: Created *after* executing 'vgdisplay
--ignorelockingfailure -v VolGroup00'
Backup Time: Sat Oct 28 13:29:00 2006
Hmm... Ok, but I'm not interested in those files. I'm interested in the
file I declared on the command line with the -f flag.
================================================
as you can see under LVM2 it does not dump the backup VolGroup00 stored
in my backup file. I can 'cat' the file and it looks normal:
# cat /tmp/.mgwork/VolGroup00
# Generated by LVM2: Sat Oct 28 13:29:00 2006

}
}
}
}
================================================
Is there some undocumented syntax change for vgcfgrestore under LVM2?
According to the man page it should work the way I am using it.
