I would like to increase the size of a 30 Gb FS. How should i do that ?

Do i have to umount the FS before increasing the FS ?

Thanks for help.

HI Emmanuel,

If you do not have Online JFS then:

1. Umount Filesystem
2. lvextend
3. extendfs
4. mount Filesystems

If it is Online JFS:

1. No need to unmount
2. Use lvextend
3. fsadm -b

Hope that helps.
Regards,

See man lvextend,extendfs and fsadm

[Steven E. Protter]

lvextend the volume logical volume
# example lvextend -L 1028 /dev/vg02/lvol1 /dev/dsk/c1t1d0

then you have a choice.

If you have online JFS you can use fsadm to extend the FS without umounting the FS.

Otherwise you must umount the FS and use extendfs to extend the fs.

# example extendfs /dev/vg02/rlvol1

swlist -l product | grep -i online

That will show you if Online JFS is installed. Its a pay for add on product, so you probably already know.
