Hi Fadia,

Do you have OnineJFS installed on your system?

Otherwise reducing an existing lvol may result in a data loss.

Cheers,
Mohan

The esaist way is using Online JFS.
But it is not recommanded reduce file system.
It may cause data false.
If you have Online JFS, you can use lvreduce and lvextend without umount file system.
If you didn't have Online JFS, backup file system which is intend to reduce.
After Backup lvremove to remove file system.
And then recreate file system appropriate size.
After remake file system recover data.
And then umount file system, which you intend to extend file system.
And lvextend file system, mount...
