Hi Prateek,

Remember , in fsadm , "-b" option takes the size in KB.

May I know what is 10240 ??? now your filesystem will reduce to 10MB aprox.

If you want to use 10 GB mention as -b 10485760

-b 10240M

vxfs fsadm: V-3-25811: cannot expand /dev/vg00/rlvol8 more than size of the underlying device - 5349376 sectors

/opt max size is ~5Gb only i want to add one of my free internal disk in so i use that space to increase file system size

Did you expand the volume first with lvextend? You need to do that before running fsadm.

Hi,
What vgdisplay says for free PE ?

# vgdisplay -v vg00 | more

Look for the PE size AND Free PE (at bottom)

then calculate ( PE Size * Free PE ) to find realy have that space.

fsadm -F vxfs -b 10240 /opt

use "M"

fsadm -b 10240M /opt

i hope this will solve your problem. assuming you have already done lvextend like below.

lvextend -L 10240

You mentioned you wanted to add a free internal disk and then extend /opt?

Also I'm not sure what difference it makes with LVM commands but I usually do system admin tasks as root with the default posix shell.

pvdisplay /dev/dsk (or /dev/disk) to verify disk is not currently in use
pvcreate -f /dev/rdsk (/dev/rdisk)
vgextend /dev/vg00 /dev/dsk/
vgdisplay -v /dev/vg00 (ensure disk was added to vg properly)
lvextend -L 10240 /dev/vg00/lvol# (that corresponds to the lvol /opt is mounted on)
fsadm -F vxfs -b 10240M /opt
lvdisplay
bdf

hi

don't use -f option to pvcreate unless recommended .use the tool like evainfo to find out the lun to be used.

suppose if ur not sure and made some mistake u will in a position to answer.
