File system

[Jeff Hagstrom]

Is there a way to check what type of filesystem I have? HFS or JFS!

[A. Clay Stephenson · Accepted solution]

You bet.

fstyp -v /dev/vg00/lvol4

You can omit the -v if you just want to know the filesystem type. Man fstyp for details.

fstyp /dev/vg03/lvol2

...jcd...

There are many ways. The easiest way to do this is to type
# mount
The system will report on what is mounted. Look for the file system you need and then type
# grep "filesystem" /etc/fstab
NOTE: Dont put in slashes!
There is an entry in fstab which tells the mount command what kind of file system it is to be mounting.

Next if you need to see more information or capabilities, there are two commands.
fsadm
fstyp

Both of these commands need an argument of the RAW file system.
I.E.
# fstyp /dev/rdsk/c0t3d0
or
# fstyp /dev/vg00/rlvol1
and
# fsadm /dev/rdsk/c0t3d0
or
# fsadm /dev/vg00/rlvol1

As always, with UNIX read the man pages. It helps quite a bit!

Hope it helps!
