Extending mount point

[OFC_EDM]

I want to extend my /patch mount point which is in vg0c. All disk in vg0c is to be assigned to this mount point.

But I noticed 741 Free PE on the last disk in the group. See below.

So I used the following command to try and extend the mount point.

fsadm -F vxfs -b 104988672 /patch

It didn't work. Am I using the correct command?
For the sectors a I calculated as follows:
PE size (32) x # of PE's 3204 * 1024 = 104988672

Cheers
(P.S. Online JFS is on the system)

Hey;

First, you need to extend the logical volume via lvextend

lvextend -l ${total_num_extents} ${lv}
fsadm -F vxfs -b ${new_size_in_k} ${mount_point}

HTH;

You must first run lvextend to "grow" the logical volume before doing the fsadm -b on the filesystem.

[Sandman!]

Did you extend lvol1 using lvextend first and then fsadm'ed it?

# lvextend -L 102528 /dev/vg0c/lvol1

# fsadm -F vxfs -b 104988672 /patch

cheers!

Extend the lvol first...then the FS. I prefer the 'm' option with fsadm to specify the filesystem size in megabytes. May help in not second guessing yourself.

fsadm -F vxfs -b 102528m /patch

Thanks I needed that kick in the pants.
The obvious was escaping me today.

This is what I did.
lvextend -l 3204 /dev/vg0c/lvol1
fsadm -F vxfs -b 104988672 /patch

I prefer to calculate the sectors be cause using the "m" option to specify megabytes always seems to waste a little space.

I'll assign points right away.
