 tail:  create the jfs2 filesystem on vxvm
ixp650 #mkfs -V jfs2 -o log=INLINE /dev/vx/rdsk/wddg/testvol

mkfs: destroy /dev/vx/rdsk/wddg/testvol (yes)? y

logform: Format inline log for <y>?

File system created successfully.

151340 kilobytes total disk space.

Device /dev/vx/rdsk/wddg/testvol:

Standard empty filesystem

Size: 302680 512-byte (DEVBLKSIZE) blocks

aixp650 #mount -V jfs2 -o log=INLINE /dev/vx/dsk/wddg/testvol /test

aixp650 #df -k

Greetings!..
Did you try using vxresize command or vxassist command...
i can give you the command usage,
vxresize -g <dg name> <volume name> <length> alloc=<disk name>

You need to specify the length to be the usable size of the free disk which you are allocating. For ex. +50G inorder to add 50GB to the existing filesystem.

another option which you can use when you have free blocks on the existing disk allocated is,

vxassist -g <dg name> growby <volume name> <length>

Hi,

Since its a VXVM Volume & AIX jfs2 filesystem..  I would think to use "vxassist" to resize the volume & chfs (I hope this is equivalent of fsadm in AIX) to resize filesystem, In HPUX this command is extendfs I believe..
