Hi all,
I shot myself in the foot, and need to pick your brains about how to
recover. My backup machine has a 500GB drive using LVM for my backup
partition. I managed to fill it up. Currently, backups are not running
(which makes me nervous), and the backuppc partition on this machine is at:
/dev/mapper/vg01-backuppc
488367552 485798240 2569312 100% /media/backuppc
I have a machine, my workstation (defiant), that I has a bunch of stuff on
it in /media/archive. The backup is about 250 GB before pooling and
compression. Well, I have been slowly migrating data from /media/archive to
another machine which now has a 1.5 TB drive. All well and good, except that
without thinking about backups, I nfs mounted the filesystem to which I am
migrating stuff from defiant. I mounted it under /media/archive, so when the
last full backup ran on defiant, it filled the filesystem on the backup
host.
I got an email from the Backuppc Genie, and started clearing some old
backups. After (I assume) Backuppc_nightly ran, I am still at 100%. I
started digging in to see why the filesystem was still full. In the
/media/backuppc/pc/defiant directory, there were two large directories,
# du -sh *
219G 869
210G 944
However, BackupPC_delete only shows backup number 869:
# BackupPC_delete -c defiant -l
BackupNumber 869 - full-Backup from 2010-01-23
and the web interface shows the same. Only 869.
Can I delete the 944 directory without adverse effects? If not, what is the
best way to free up this drive space?
Also, I have another 120GB of free space in another volume group. Is there a
way to integrate that into the backup filesystem? With all the hard links, I
wasn't sure how best to allocate the space.
/dev/mapper/vg00-archive
156962116 32840 156929276 1% /media/archive
Unfortunately, since I use LUKS encryption on the drives, spanning a VG
across two drives is contraindicated. (It decrypts the first drive, but not
the second, so the volume group can't open.) Can I still use the 150GB on
vg00-archive in /media/backuppc?
Thanks,
--b
