Configure On CentOS 6.5

Since I use disks I start with installing vchanger

The link above has a script but it looks like the one on sourceforge (which is referenced in the link) is newer and compiles. Even then, I decided to pull the rpm from pbone 

wget ftp5.gwdg.de/pub/opensuse/repositories/home:/pstorz/CentOS_CentOS-6/x86_64/vchanger-0.8.6-10.3.x86_64.rpm
yum install vchanger-0.8.6-10.3.x86_64.rpm
  • I am going to start with one drive so first I am going to format it (create a partition first (cfdisk)):
  • Quote:

Assuming the drive was assigned node /dev/sdc, the partition can now be formatted and labeled using: 

mke2fs -t ext4 -O large_file /dev/sdc1

This will create a new ext4 file system on the partition. Now unplug the drive, wait a few seconds, then plug it back in. After re-attaching the drive, the name of the symlink in /dev/disk/by-uuid pointing to the filesystem partition's device node, (/dev/sdc1 in the example above), will reveal the UUID that can be used in a magazine directive in a vchanger configuration file to assign the removable drive to an autochanger. On many systems, the UUID of the filesystem can also be determined with the blkid command. 

ls -al /dev/disk/by-uuid/

The Bacula Storage Daemon does not usually run as root. Since vchanger will be invoked by the Storage Daemon, and so will run as the same user it does, permissions for the magazine's mounted filesystem must be set to allow write access to the user that the Storage Daemon runs as. This can be done by mounting the new partition somewhere, then using chown and chmod to set the appropriate permissions to allow write access for the user that the Storage Daemon runs as. 

mkdir /media/temp
mount /dev/xvdc1 /media/temp
chown bareos:bareos -R /media/temp

Need to get autofs up and running so it mounts the disks and stuff: 

yum install autofs

nano /etc/auto.vchanger
  • add
# /etc/auto.vchanger
*          -fstype=auto,rw,sync       :/dev/disk/by-uuid/&
# eof
  • Then:
nano /etc/auto.master
  • add
/mnt/vchanger      /etc/auto.vchanger        --timeout=30
  • then
service autofs restart

ls -al /mnt/vchanger/UUID so 

ls -al /mnt/vchanger/3c22af77-4881-4a7f-bcfc-517744c964db

Note: After restarting the autofs daemon, whenever a file or directory with a full path beginning with '/mnt/vchanger' is accessed, the autofs filesystem will search the map defined in the /etc/auto.vchanger file for a key matching the path being accessed. In this case, the only key in /etc/auto.vchanger is the wildcard '*', meaning any path name beginning with '/mnt/vchanger' will match. Autofs then automatically mounts the device mapped to the wildcard key at the path being accessed. The /etc/auto.vchanger map file specifies the device to be mounted as /dev/disk/by-uuid/&. The '&' is substituted for the key value. For example, when a program attempts to access /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35 (or any files or directories below it), the autofs daemon will look at the auto.vchanger map for the key 9667f83c-6150-44c7-b0d4-57564f174b35 and discover that it should mount /dev/disk/by-uuid/9667f83c-6150-44c7-b0d4-57564f174b35 at /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35 with mount options '-fstype=auto,rw,sync'. After a period of 30 seconds of no activity, autofs will automatically unmount the device.

Always make sure autofs is working properly before continuing with setting up vchanger. If using the above autofs config files, when you plug in a USB drive with filesystem UUID of, say, 9667f83c-6150-44c7-b0d4-57564f174b35, you should be able to list its contents with the commandS
