i want to increase my file system using the unallocated espace. you can see below my current config and the config i hope to have.
Is it possible to do that without reinstalling the system?

Shalom,

lvextend
umount the filesystem
extendfs

Simple unless the umount won't work. Then you either take the system to single user mode or use OnlineJFS (fsadm) to expand the filesystem in question without umount.

Root fs, / must be contiguous, and you can't extend it. The only way to deal with this is to do an Ignite backup, restore it and during the restore, intervene to set up a larger root fs.

my files systems are vxfs. does the online JFS work?

Hi

If ONLINEJFS is installed in System

lvextend
fsadm

if ONLINEJFS is not installed

lvextend
umount filesystem
extendfs

For root there is is way to extend but the best way is to ignite the box

Hi Kacou,
in your case, you want increase all the FS in a VG00, you must create a ignite tape, and resize all FS in install process.

regards.

i think you only need at this moment is to increase the /usr file system.

use the above file system increase commands. But make sure you have OnlineJFS installed in your system.
