Hi Martin,
Thanks, thats it!
LVM adds a symbolic for /dev/mapper/... Devices like this:
[...]
01-May 06:25 xen01-dir JobId 144: BeforeJob: Logical volume
"bacula-snap_xen01_domU1" created
01-May 06:25 xen01-dir JobId 144: BeforeJob: File:
`/dev/system/bacula-snap_xen01_domU1' ->
`/dev/mapper/system-bacula--snap_xen01_domU1'
01-May 06:25 xen01-dir JobId 144: BeforeJob: Size: 43 Blocks: 0
IO Block: 4096 symbolic link
01-May 06:25 xen01-dir JobId 144: BeforeJob: Device: dh/13d Inode: 32416
Links: 1
01-May 06:25 xen01-dir JobId 144: BeforeJob: Access: (0777/lrwxrwxrwx) Uid: (
0/ root) Gid: ( 0/ root)
01-May 06:25 xen01-dir JobId 144: BeforeJob: Access: 2008-05-01
06:25:05.971870511 +0200
01-May 06:25 xen01-dir JobId 144: BeforeJob: Modify: 2008-05-01
06:25:05.971870511 +0200
01-May 06:25 xen01-dir JobId 144: BeforeJob: Change: 2008-05-01
06:25:05.971870511 +0200
[...]
If i use the /dev/mapper Device Files Bacula makes the RAW Device Backup, thats
what i want!
Eventually the Support of LVM Symbolic links (or links pointing to a Block
Device) can be an Enhancement for bacula for better usage or transparancy?!
It makes sence, to add this fact in the Documentation ....
Regards,
Peter
