[Bacula-users] centos7 autoloader problem - ok in Cento6
I am seeing a wierd autoloader problem in Centos7 I have an hp (Sun) Sl24 changer with one lt04 drive in it. It works fine in mt/mtx/bacula etc, perfect. The problem I am seeing is that if I pull a magazine to change tapes, or use the mailslot to load a tape, the system hangs on a device wait for the autoloader. The system is not hung, just the job that is using the autoloader, like bacula. If I unmount the drive in bacula before pulling the magazine, then nothing can access the drive, 'mtx status' gives a sense error, and all others, like 'mtx load 13' just hangs. The only way to clear it is to reboot! sg-reset, and all scsi bus reset programs do not clear the error. As I said, this is working fine in centos6 and I did report it as a bug in Centos7 bug tracking system. Anyone else see this or come up with a workaround? Having to reboot after loading restore tapes is a real pain!!! +-- |This was sent by p...@isone.biz via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- -- Comprehensive Server Monitoring with Site24x7.

[Bacula-users] Bacula error? Attr spool not clearing?
Hi. I am using Bacula 7.0.5. I havde disk spooling turned on (80G). During bacups, it spools to the data spool, and attr spool, then writes data to tape as 80g fills up. When it is done, the data spool shows empty, but the attr spool doesnt: Used Volume status: Reserved volume: PH0036L4 on tape device LTO-4-Drive (/dev/nst0) Reader=0 writers=0 reserves=0 volinuse=0 Data spooling: 0 active jobs, 0 bytes; 38 total jobs, 80,530,662,250 max bytes/job. Attr spooling: 0 active jobs, 700,781,712 bytes; 38 total jobs, 700,781,712 max bytes. As you see, nothing is running, but the attr spool show 700m of data in it. Is this a bug? Anyone know?

By the way, in case you have not noticed, there are three white

I notice now, thanks.
CommunityDiskBackup.pdf has the same old problem in 2.1 Grouping
Storage Devices: as usual, it talks multiple devices and shows 2
Device definitions with Archive Device = /disk in both. Personally I
don't know how to mount multiple physical devices in the same /disk at
the same time and keep them separate too.
Bacula can only mount one device in any given Device section at a time,
but in an Autochanger (virtual or not) there are multiple Devices and
each can have its own directory. However, if you use different
directories, you must use different Media Types otherwise, Bacula will
not know the right directory to look in for fixed disks.
Same goes for 2.2 Virtual Autochanger: it doesn't let you write to
multiple (disk) devices, it lets bacula treat a single Archive Device
as multipe devices -- presumably for concurrent access.
I am not sure why you believe the above. Each Device can have a
different Archive Device path. The examples probably use the same
directory so that it does not get too complicated (with Media Types and
all). I suggest you just try using different disk devices and see what
happens.
I do not see how that is possible. It makes sense that each of the
virtual autochanger's Devices use a different Media Type, since that
forces volumes to only be loadable on the Device in which they exist.
What makes no sense to me is how that is defined in the Director config.
The Media Type directive in the Storage resource in bacula-dir.conf is
required, and as far as I can tell is limited to a single Media Type. If
a single Storage resource in the Director cannot utilize multiple Media
Types, then I do not see how a SD virtual autochanger using Devices with
different Media Types is addressable as a single Storage resource in Dir.
In my testing, I used the below config. Note that I specified a
comma-delimited list of the media types in the Media Type directive of
the Storage resource in bacula-dir.conf (Media Type = disk0,disk1). Dir
and SD start and run normally, accepting the syntax. Jobs run without
errors, but only ever utilize the Device with Media Type = disk0, first
media type listed. If I attempt to run two concurrent jobs, then they
run sequentially, with one waiting on storage until the other completes.
No job can use any volume that is not Media Type disk0. If I switch
the order of the media types listed in the Media Type directive to Media
Type = disk1,disk0, then all jobs will write to the Device with Media
Type disk1 and never any volumes with media type disk0.
This leads me to believe that while the SD has no problem with a virtual
autochanger that has Devices with different Media Types, it isn't
possible to define a single Storage resource in Dir that can utilize it.

Re: [Bacula-users] CentOS 6.6 SELINUX Problems BACULA 5.2.18 [Help]
Hey Simone Thank you for your input I followed your instructions and I was able to fix (*some of) the SELinux https://danwalsh.livejournal.com/24750.htmlerrors with audit2allow https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security-Enhanced_Linux/sect-Security-Enhanced_Linux-Fixing_Problems-Allowing_Access_audit2allow.html backup/restore seems to be working again I will continue testing and see if I encounter any more problems. Things was not as easy or as straight forward as you presented it but after a lots of reading on SELinux and audit2allow http://selinuxproject.org/page/Audit2allowRecipe and countless trial and errors I was able to fix my backup/restore problems. For some reason most of the problems seems to be related to bacula-sd wanting to read,write,etc on files and directory, I will continue watch and update you. Thanks Again On 11/10/2014 09:45 AM, Simone Caronni wrote: It's a difficult topic but it's very rewarding :) My suggestion is, assuming you have the system in SELinux enforcing mode: - Install policycoreutils-python for SELinux debugging tools - Ask for relabeling of the system (fixfiles onboot) reboot to let the actual relabel happen - Stop Bacula daemons - Clear files in /var/log/audit/ - Set system in permissive mode (setenforce 0) - Start bacula and do whatever you need to test - Launch audit2allow -a or look directly in /var/log/audit/audit.log for hints - Fix what you need to fix and re-enable SELinux (setenforce 1) Redhat SELinux administration's guide for RHEL 7/6: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/SELinux_Users_and_Administrators_Guide/index.html https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security-Enhanced_Linux/index.html Regards, --Simone On 10 November 2014 15:10, Humphrey Bryant hbry...@fogadaley.com mailto:hbry...@fogadaley.com wrote: Hey Simone, Thanks for the reply, indeed you are right its not related to bacula but I was just trying to get some feedback from other users who might have experienced this issue.

It was after I temporarily disabled SELINUX backup start working again, so I am of the conclusion that SELINUX is at fault here.. I need some help getting SELINUX to play nice with Bacula on CENTOS 6.6, can anyone here help me out please. any one can help me create a policy or something, I don’t want to upgrade my production server and have this same problem. First of all, you can try to relabel your filesystem in case you have some mislabeled file; as root do fixfiles onboot and reboot the system. Second, you can delete all files in /var/log/audit/ and make the problem reappear, so you can debug the SELinux permission problems with audit2allow -a or by looking directly at a clean /var/log/audit/audit.log file. Then, it's worth saying that /backup is not a path that is part of SELinux labels. It is not a problem by itself (it should work anyway) but my suggestion is to use /bacula/ as the path for your backups. # 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

I'm slightly paranoid about security so I mainly use it because of the protection it offers and because it comes on by default.
