resize a volume or file system partition?

Can u tell how did u created the filesystem with 300GB size over a 500GB volume ? paste exact commands...

Also paste

# vxprint -qhtg sapprddbdg sapdbvol01
# df -k /oracle
# fstyp -v  /dev/vx/rdsk/sapprddbdg/sapdbvol01

If for sure FS & Volume have different sizes, it will be treated as inconsistent by fsck ... I am wondering how you were able to mount it... I would strongly recommend NOT to unmount the FS ... since vxresize command needs FS to be mounted (just in case if resize is needed)...

Strange ... as per vxprint output .... 1677721600 * 512 / (1024*1024*1024) = 800G can u tell the exact command you have used to create the filesystem & volume ?

Also, since the diskgroup has more space available, after the file system has grown up to 800GB you could use vxresize command to grow maximum available space. Use the vxresize command when resizing both the volume and the file system. The vxresize command guarantees that the file system shrinks or grows along with the volume.

The command syntax would be.

1. Verify that there is enough space available to grow the volume.

     vxassist maxgrow <volume-name>

2. Grow the filesystem:

     cd /usr/lib/vxvm/bin/
     ./vxresize -F <filesystem type> -g <diskgroup> <volumename> + <size>

   example:
     ./vxresize -F vxfs -g dadbdg-hds voldb00 +100g

Note: Please mark this note as solution if this note helps.

So you have two tasks here: a) You have a case where volume & fileystem size are not matching, first you have to fix this... see below on how to do this.. b) once above is done, then you can think of reducing the FS & volume to 400G (as this was your original requirement) # /usr/lib/fs/vxfs/fsadm -b 1677721600 /oracle should extend your filesystem to 800G I would suggest to do this first... once this is done (i.e your volume & filesystem size is exactly matching), You can verify the same once again by pasting a "fstyp -v " Once above is done then you can shrink your filesystem & volume to 400G by running # vxresize -g -b 400G Gaurav

there is a typo in last command... it should be

# vxresize -g <diskgroup> -b <volume> 400G
