Yohoo!
Just for my own curiousity:
I have a LVM volume which is presentet through iSCSI to another box. On
the other box I used fdisk to create a partition and formatted the
partition with ext3.
Now I'm performing a backup on the local iSCSI/LVM server like follows:
Taking a snapshot of the LV:
lvcreate -s -p r -c 64K -L 30G -n snap_backup /dev/vg/backup
Setting up the lo-device with the calculation for the partition start:
losetup -o$[512*64] /dev/loop1 /dev/vg/snap_backup
Mounting:
mount /dev/loop1 /srv/snap/ -t ext3 -o ro
Now my question is about the file system on the partition. Is it
consistent? Would it be better to perform a fsck before mounting?
Or can I rely on the above procedure to gain always a proper filesystem?
