Resize file system

czezz · 09-19-2007, 09:18 AM

Let's say that file system layout looks like this:

Code:

/                   c1t0d0s0 1400 MB
/usr                c1t0d0s1 10000 MB
/export/home        c1t0d0s3  100 MB
/opt                c1t0d0s4 23229 MB
empty/free          c1t0d0s5 30000 MB

Suddenly admin realized that root partitioon (/) is too small and will overfull very soon.
Is there any way to resize root file system adding to it 10000 MB from c1t0d0s5 (hope there is no need to use metadevices and software RAID).

http://gparted.sourceforge.net/
it's often included in knoppix, so you can boot knoppix from cd and make the resize

according to google:

http://www.unixadmintalk.com/f34/ufs-resize-783/
you can extend your ufs partitions.

some claim you can even shrink them:

however i don't think it will be necessary in your case, cause you should be able to delete your "empty" partition.

A common situation.

You can do it if s0 and s5 are contiguous, which is unlikely. To be sure, post prtvtoc output.
Otherwise, more intrusive solutions like shifting partitions or backup/restore operations are required.
