chfs reduce JFS gives error

[saucyboy]

Guys

I created a FS on a 5.3 box and need to reduce the FS

I enter chfs -a size=-1G /****

the error i get is

chfs: 0506-908 Cannot reduce size of file system.

its a standard JFS

any reason , i thought this reduce FS functionality comes with 5.3

Nope, only jfs2

The manpage for chfs indicates that reducing is possible for JFS2, but not JFS.

I'm talking carp

the command should work

chfs -a size=10000 /usr

looks like it does not work on standard JFS i get

chfs -a size=10000 /****
chfs: 0506-908 Cannot reduce size of file system.

I will try it on jfs2 ..

many thanx guys

There is a third party tool to reduce JFS size but it isn't freely available. In AIX53 it is built-in, but only for JFS2.

If your machine is 64-bit kernel, my advice is to go for jfs2 as this has a better performance + it will do your job when reducing the lv!
