Hello,
I'm facing 2 differents issues with BackupPC :
*) Locking
Transfer is done using rsync+ssh, I've a task that started at 4am and was stuck (backup still processing but no activity on disk)
I was forced to kill rsync process manually, DumpPostUserCmd was called then.
Here's the list of process that was running :
backuppc 521 0.0 0.0 5556 3196 ? S 04:51 0:05 /usr/bin/ssh -q -x -l root remote /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive . /home/snap/something/
root 524 0.0 0.0 5104 2720 ? Ss 04:51 0:18 /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive . /home/snap/something/
backuppc 525 8.3 1.9 334108 331164 ? S 04:51 40:02 /usr/bin/perl /usr/share/backuppc/bin/BackupPC_dump something
Strace on rsync : it was waiting like select(1, ...)
This problem occured twice since i'm using BackupPC (july 2008), which is handling 18 hosts (Pool Size = 42 GB).
*) BackupPC doesn't worked correctly on one host

#86 was supposed to be a full backup but when browsing I found out that it's missing a lot of directory ( /bin /home ...)
size of backup# on disk
2,8G 86
9,3G 87
9,4G 88
Moreover, when trying to read logfile, to found out anything : file XferLog seems corrupted
# /usr/share/backuppc/bin/BackupPC_zcat XferLOG.86.z
/usr/share/backuppc/bin/BackupPC_zcat: can't uncompress XferLOG.86.z
# hexdump -C XferLOG.86.z | head -n5

BackupPC version is 3.1.0 (from Debian etch/backports 3.1.0-2~bpo40+1).
The last one isn't really directly related to BackupPC :
* I'm using LVM2 to make snapshot of ext3 device and then mount it (read-only) : this is done in DumpPreUserCmd .
* when backup completed, it's unmounted and snapshot is removed in DumpPostUserCmd
Time to time, when mounting snapshot, I'm having issue in syslog :
EXT3-fs: dm-34: orphan cleanup on readonly fs
ext3_orphan_cleanup: deleting unreferenced inode 65456043
...
ext3_orphan_cleanup: deleting unreferenced inode 65456045
EXT3-fs: dm-34: 11 orphan inodes deleted
EXT3-fs: recovery complete.
EXT3-fs: mounted filesystem with ordered data mode.
Is this a correct behaviour ?
Thanks,
