expanding file

F5 BIGIP software uses CentOS as the base system with TMOS. You need to extend the CentOS volumes.

Here are the steps I did in my lab unit (12.0.0 Final):

[root@LABBIGIP1:zrd DOWN:Disconnected] config df -h /config

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/vg--db--sda-set.20._config 3.2G 351M 2.7G 12% /config

[root@LABBIGIP1:zrd DOWN:Disconnected] config lvextend -L+1G /dev/mapper/vg--db--sda- set.20._config

Extending logical volume set.20._config to 4.17 GiB

Logical volume set.20._config successfully resized

[root@LABBIGIP1:zrd DOWN:Disconnected] config df -h /config

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/vg--db--sda-set.20._config

                  3.2G  351M  2.7G  12% /config

[root@LABBIGIP1:zrd DOWN:Disconnected] config resize2fs /dev/mapper/vg--db--sda-set.20._config

resize2fs 1.41.12 (17-May-2010)

Filesystem at /dev/mapper/vg--db--sda-set.20._config is mounted on /config; on-line resizing required old desc_blocks = 1, new_desc_blocks = 1

Performing an on-line resize of /dev/mapper/vg--db--sda-set.20._config to 1092608 (4k) blocks.

The filesystem on /dev/mapper/vg--db--sda-set.20._config is now 1092608 blocks long.

[root@LABBIGIP1:zrd DOWN:Disconnected] config df -h /config

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/vg--db--sda-set.20._config

                  4.2G  352M  3.6G   9% /config
