Resizing filesystem online on HP-UX

Resizing filesystem online on HP-UX

Check the volume group and logical volume being used by the filesystem

root@hp-ux:/root # bdf /example
Filesystem kbytes used avail %used Mounted on
/dev/vg01/lvol14 32768 2141 28720 7% /example

This logical volume has 32MB and uses 2 PE

root@hp-ux:/root# lvdisplay /dev/vg01/lvol14
— Logical volumes —
LV Name /dev/vg01/lvol14
VG Name /dev/vg01
LV Permission read/write

Each PE has 16MB and there is 1047 available

Checking if it is possible to resize online the filesystem. In some HP-UX versions, this feature is not available

root@hp-ux:/root# swlist -l product | grep -i jfs
AONLINEJFS B.05.01.02 OnlineJFS 5.0.1 Integration Product
JFS B.11.31 Base VxFS File System 4.1 for HP-UX
OnlineJFS01 5.0.31.6 Online features of the VxFS File System

Extending filesystem to 5120MB

root@hp-ux:/root# lvextend -L 5120 /dev/vg01/lvol14
Logical volume “/dev/vg01/lvol14” has been successfully extended.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

Increased logical volume to 320 PE adn 5120MB

root@hp-ux:/root# lvdisplay /dev/vg01/lvol14
— Logical volumes —
LV Name /dev/vg01/lvol14

Now running fsadm to increase the filesystem

root@hp-ux:/root# fsadm -F vxfs -b 5120m /example
UX:vxfs fsadm: INFO: V-3-25942: /dev/vg01/rlvol14 size increased from 32768 sectors to 5242880 sectors

root@hp-ux:/root# bdf /example
