This is continuing an old thread and may be slightly OT, but here it goes
anyway..
I've got a BackupPC server running on LVM2 and RAID1 (4 drives, 2 raid1
partitions made into 1 logical partition) and using reiserfs. I've got
about 135GB of space being used now and plan on increasing that
substantially soon. I want to back up to an external HD, so this is what I
was trying to do:
lvcreate -L600M -s -n poolsnap /dev/backupvolume/logicalbackupvolume
mnt /dev/backupvolume/poolsnap /snapshot
cp -a /snapshot /mnt/ (/mnt has an external USB drive
mounted to it)
lvremove /dev/backupvolume/poolsnap
I'm using 600M, because that is the largest snapshot lvcreate would let me
do. I'm doing this creation of the snapshot and cp when the backuppc is
idle (during the day). After it copies about 2.5GB, I start getting errors
like this:
ReiserFS: warning: is_tree_node: node level 48476 does not match to the
expected one 1
ReiserFS: dm-3: warning: vs-5150: search_by_key: invalid format found in
block 96189477. Fsck?

ReiserFS: dm-3: warning: vs-13070: reiserfs_read_locked_inode: i/o failure
occurred trying to find stat data of [1858555 1858580 0x0 SD]
I am new to LVM, so I may be doing something boneheaded. I've reviewed the
LVM HOWTO, but can't seem to find much detail about how to tell if a
snapshot is filling up. Any suggestions welcome.
