extend /opt

[Jes Yu]

If I need to extend fs /opt, should I put the system in service mode?
I extened its LV, but I cannot umount /opt when the system is up to run extendfs command. Anyone has how to steps? Thank!

Hi,

Boot in Single user mode and extend the file system.

If you have Online JFS installed ,without unmounting you can extend it.

LIJEESH,

Hi,

Its not a free product and we can get the information about it from software.hp.com site.

Check it whether it installed,
# swlist -l product|grep -i online
OnlineJFS B.11.23.0609 Online features of the VxFS File System
OnlineJFS01 4.1.008 Online features of the VxFS File System

Hi Jes,

Do you have online JFS installed :

# swlist | grep -i jfs
B3929EA B.11.31 HP OnLineJFS (Server)

If you have then you can run the following command :

/sbin/fsadm -F vxfs -b XXXXM /opt

where XXXX equates to the total new size of /opt.

If you do not have Online JFS then you will need to boot the server into single user mode and then :

mount /usr

extendfs -F vxfs /dev/vg00/rlvol4

bdf /opt

Regards,

No, not installed.
If I need to extend /usr, would I do the same to put the system in single mode?
