are you refering to "fsadm" ?

yes you can

[kunjuttan]

can you please give me the syntax?

[Johnson Punniyalingam]

step 1 :-

fsadm -F vxfs -b M

step 2 :- reduce logical volume by lvreduce:

lvreduce -L

[kunjuttan]

But this wil result in data losing.right?

Yes, you can use "fsadm" command to increase or decrease value while file system online.

But, before that, check that you have OnlineJFS license to use fsadm.

hi,

its recomended to make a backup of the FS, before you play with the LVM.

I do it always, before start to work on the system.

Before doing any system activities or maintenance (LVM, Kernel, patch installation etc.) its highly recommended to take system backup.

if you all the LVM patches are up to date,

no margin for data lose,

Its better to take full backup of the file system before you reduce.

my 2cents .

Thanks,
