15.4. Configuration Examples

Procedure 15.1. How to Label a Gluster Brick

1. Create a directory to mount the previously formatted logical volume. For example:

   ~]# mkdir /mnt/brick1

2. Mount the logical volume, in this case /dev/vg-group/gluster, to the /mnt/brick1/ directory created in the previous step.

   ~]# mount /dev/vg-group/gluster /mnt/brick1/

   Note that the mount command mounts devices only temporarily. To mount the device permanently, add an entry similar as the following one to the /etc/fstab file:

   /dev/vg-group/gluster    /mnt/brick1  xfs rw,inode64,noatime,nouuid      1 2

   For more information, see the fstab(5) manual page.
3. Check the SELinux context of /mnt/brick1/:

   ~]$ ls -lZd /mnt/brick1/
   drwxr-xr-x. root root system_u:object_r:unlabeled_t:s0 /mnt/brick1/

   The directory is labeled with the unlabeled_t SELinux type.
4. Change the SELinux type of /mnt/brick1/ to the glusterd_brick_t SELinux type:

   ~]# semanage fcontext -a -t glusterd_brick_t "/mnt/brick1(/.*)?"

5. Use the restorecon utility to apply the changes:

   ~]# restorecon -Rv /mnt/brick1

6. Finally, verify that the context has been successfully changed:

   ~]$ ls -lZd /mnt/brick1
   drwxr-xr-x. root root system_u:object_r:glusterd_brick_t:s0 /mnt/brick1/
