Dear bacula users,
since some time I have problems recovering the owner, group and permission of
(some) directories. Today I took the time to trace that down:
I am doing an interactive restore of
nfs2:/export/user2/litauer/mgmt/backend/mailman and
nfs2:/export/user2/litauer/mgmt/backend/live. Baculas index shows the correct
ownership, group and permissions:
$ pwd
cwd is: /export/user2/litauer/mgmt/backend/
$ dir mailman
drwx--x--x 3 litauer 1050 65 2012-05-18 23:20:10
/export/user2/litauer/mgmt/backend/mailman/
$ dir live
drwx--x--x 3 litauer 1050 4096 2012-05-18 23:20:10
/export/user2/litauer/mgmt/backend/live/
I "mark" both directories and start a recover to the original backup-client and
filesystem. Bacula dir and client fd are running version 5.2.13. The clients
filesystem is of type xfs.
The recovered directories look like this:
nfs2:/export/user2/litauer/mgmt/backend # pwd
/export/user2/litauer/mgmt/backend
nfs2:/export/user2/litauer/mgmt/backend # ll -d live mailman
drwxr-x--x 3 root bacula 4096 Mar 15 10:38 live
drwx--x--x 3 litauer employee 65 Mar 15 10:38 mailman
nfs2:/export/user2/litauer/mgmt/backend # ll -dn live mailman
drwxr-x--x 3 0 114 4096 Mar 15 10:38 live
drwx--x--x 3 14255 1050 65 Mar 15 10:38 mailman
As you can see, permissions of both dirs are correct. Ownership and group or
"mailman" too. But owner and group of "live" are not restored.
While restoring I did an strace on chown-calls at the clients bacula-fd. I can
see lots of chown calls for all restored files, e.g.
[pid 12033] chown("/export/user2/litauer/mgmt/backend/mailman", 14255, 1050) = 0
[pid 12033] chown("/export/user2/litauer/mgmt/backend/mailman/.svn", 14255,
1050) = 0
[pid 12033] chown("/export/user2/litauer/mgmt/backend/mailman/.svn/prop-base",
14255, 1050) = 0
[pid 12033] chown("/export/user2/litauer/mgmt/backend/live/.svn/prop-base",
14255, 1050) = 0
[pid 12033]
chown("/export/user2/litauer/mgmt/backend/live/.svn/prop-base/CommandLine.exe.config.svn-base",
14255, 1050) = 0
But I miss the chown call for /export/user2/litauer/mgmt/backend/live and its
subdirectory ".svn". Other subdirectories inside of "live" are restored
correctly.
The problem is not exclusively present for this example recovery. It happens
nearly at every restore I am doing, regardless on which client the data is
restored.
I wonder if this is a bug in bacula-dir or bacula-fd ... but this bug would be
that serious, I cannot believe nobody else would have registered. So it seems
as if it is a local problem. Any ideas?

Kind regards
