Hi, I need to decrease a Filesystem to free space that I need to give to another LV. The FS is a Jfs2. Both LV and FS are managed by HACMP, I'd like to use CSPOC in "smitty hacmp" to configure this system.
I suspect that I need to destroy FS/LV and rebuild with smaller size as I need.

What is the right way? thanks.

Hi,

No need to remove the FS/LV, if those filesystems are JFS2 then you can shrink the filesystem.

Smitty cl_lvm
shared filesystems
enhanced journal filesystems
change/show characteristics of a shared enhanced journaled FS
select the filesystem you want to shrink
goto SIZE of file system (-10M) this removed 10M from the filesystems you can select -10G removes 10GB
Hit enter an all done.

Hope this helps.

Hi, I tried to shrink when I was waiting for reply, as you write I done all from smitty hacmp, cspoc.
1. shrink fs, without unmount it, specifying new size. (forunately my fs was empty)
2. shrink lv, specifying new LP number.

At this time I had some free LP that I have allocate to another LV and FS.

Thank you.
