Re: [Bacula-users] bacula backups failing

Hello,

Recently backup jobs started failing when I try to backup a remote client and when I tried to back up the local client (that is the bacula server itself). The remote client is called 'beta-new.mydomain.com' and the bacula server is called 'ops.mydomain.com'.

23-Aug 01:30 ops.mydomain.com JobId 94: BeforeJob: Can't open /var/bacula/.my.cnf for writing at /etc/bacula/make_catalog_backup.pl line 89, <FP> line 10.

These are the permissions I have on the file it's complaining about:
[root@ops:~] #ls -lh /var/bacula/.my.cnf
-rwxrwx--- 1 bacula bacula 69 Jul 25 05:08 /var/bacula/.my.cnf

And here's the output of messages:
23-Aug 01:30 ops.mydomain.com JobId 94: shell command: run BeforeJob "/etc/bacula/make_catalog_backup.pl mydomainCatalog"

23-Aug 01:30 ops.mydomain.com JobId 94: BeforeJob: Can't open /var/bacula/.my.cnf for writing at /etc/bacula/make_catalog_backup.pl line 89, <FP> line 10.

I was hoping I could get some advice on how to solve these issues. I tried googling around but couldn't anything that could've helped.

Are you running with SELinux in targeted mode?

From what I've seen you're not running a standard configuration on RHEL. This is the place where I have the make_catalog_backup.pl file in the packages:

# rpm -ql bacula-director | grep backup.pl

/usr/libexec/bacula/make_catalog_backup.pl

Keep in mind that if you move all files around and install Bacula by hand and have SELinux enabled you should also adjust file contexts, policy, etc. The folder /var/bacula is not in the default RHEL/Fedora SELinux policy:

# semanage fcontext -l | grep bacula

/bacula(/.*)? all files system_u:object_r:bacula_store_t:s0

/etc/bacula.* all files system_u:object_r:bacula_etc_t:s0

/etc/rc\.d/init\.d/bacula.* regular file system_u:object_r:bacula_initrc_exec_t:s0

/usr/sbin/bacula.* regular file system_u:object_r:bacula_exec_t:s0

/usr/sbin/bat regular file system_u:object_r:bacula_admin_exec_t:s0

/usr/sbin/bconsole regular file system_u:object_r:bacula_admin_exec_t:s0

/var/lib/bacula.* all files system_u:object_r:bacula_var_lib_t:s0

/var/log/bacula.* all files system_u:object_r:bacula_log_t:s0

/var/run/bacula.* regular file system_u:object_r:bacula_var_run_t:s0

/var/spool/bacula.* all files system_u:object_r:bacula_spool_t:s0

/var/spool/bacula/log(/.*)? all files system_u:object_r:var_log_t:s0

If you are indeed running a custom Bacula on a RHEL system with SELinux enabled you should definitely check your file contexts.
