Very Computer

I am new to Sun and Solaris.  We installed Solaris with the following
filesystem.  After a couple of weeks it was decided that we really
needed to increase the size of /var.  We have unused space on /bogus.
Is there anyway to increase the size of /var and decrease the size of
/bogus without reinstalling the system?

I did look at Infodoc 17303 on sunsolve but was still confused on this
issue.  We are using ufs as the filesystem.

Filesystem            kbytes    used   avail capacity  Mounted on
/proc                      0       0       0     0%    /proc
/dev/dsk/c0t0d0s0     144172   56652   73103    44%    /

/dev/dsk/c0t0d0s3      37871   11221   22863    33%    /var

/dev/dsk/c0t0d0s1     482824  280553  153989    65%    /usr/openwin
swap                 1409328     296 1409032     1%    /tmp

Thanks for the help.

1. Make a new mount point, say /varnew
2. Copy /var to /varnew
3. use format to increase the size of the partition (back up the other
partition if there is data there)
4. mv /varnew /var

Now for the caveats:

the partition you are taking from _MUST BE ADJACENT TO /var_!  You
cannot have a non-contiguous partition.  If the space is separated,
consider using a volume manager like Solstice Disksuite or Veritas, but
there are other issues with that.

You also need enough disk space to copy the contents of /var to; from
your vfstab file above, it looks like you do for /var, but I don't know
about the filesystem you're taking the space from -- remember that data
will be destroyed unless you back up the donor filesystem.

Good luck!

>/var is not critical to the current operation of the system (like, say,
>/usr) so you could do the following:
