Increasing Thumper filesystems for DPM

The file systems on Thumper disk servers can be grown on demand. Here follows the recipe to increase the file systems.

Increase the logical volume (/dev/data/atlasprd) on the Thumper. In this example, increase it 4.4 TB (SI):

[root@hooi-ei-01 ~]# lvresize -L 4T /dev/data/atlasprd
  Extending logical volume atlasprd to 4.00 TB
  Logical volume atlasprd successfully resized

Increase the size of the XFS file system:

[root@hooi-ei-01 ~]# xfs_growfs /export/data/lv0
meta-data=/dev/data/atlasprd     isize=256    agcount=32, agsize=16777216 blks
         =                       sectsz=512   attr=0
data     =                       bsize=4096   blocks=536870912, imaxpct=25
         =                       sunit=0      swidth=0 blks, unwritten=1
naming   =version 2              bsize=4096
log      =internal               bsize=4096   blocks=32768, version=1
         =                       sectsz=512   sunit=0 blks, lazy-count=0
realtime =none                   extsz=4096   blocks=0, rtextents=0
data blocks changed from 536870912 to 1073741824

The system should now see the modified size of the file system:

[root@hooi-ei-01 ~]# df -hH | grep -A 1 atlasprd
/dev/mapper/data-atlasprd
                       4.4T   1.6T   2.9T  37% /export/data/lv0

The DPM server has to be restarted to make it aware of this extra disk space:

[root@tbn18 ~]# service dpm restart
Stopping dpm:                                              [  OK  ]
Starting dpm:                                     

Done!
