[Denver Osborn · Accepted solution]

# fstyp -v /dev/vg00/lvol4

Hi,

Try fstyp command

EX: fstyp -v /dev/vg00/lvol4 will show you the version.

And yes you need to use -o largefile for filesize bigger than 2GB

According to ITRC document UFSKBRC00009741, fstyp doesn't give the exact version of JFS installed (at least for 3 and above). This document explains it pretty good.

fstyp does tell you it is 3.0 or 3.1, another way is
swlist -l bundle | grep -i jfs

Sorry, I mean it does not...

Hi Irving,

It's most likely that you have ver 3.x - the only way to know which is by the bundle #.

B5118BA => ver 3.1
B3929BA => ver 3.3

Do
swlist | grep -i jfs & see which you have

HTH,
Jeff
