Solaris

my only comment here is that you cannot grow the root FS.

Your only route here would be to:

1. use "du -sk" to find out where your full directories are;
2. check in places such as /var/crash, /var/core, /var/tmp and delete anything that you can;
3. looks like /export/home is in your root file system - check that area too for users storing large files.

the only other way that this is to backup your important data and re-install the OS and change the layout of the disk at the same time.

@ admin@solaris:
the OP doesn't use metadevices... so your solution won't work.

@ OP
if you have a second (new) disk that you can attach to your system, you can use the "liveupgrade" option to grow your filesystem. look at docs.sun.com for "liveupgrade". also you can do a "ufsdump" of your filesystems to a new (bigger) disk... but as grippo already said, there isn't a growfs solution with your configuration.

I believe there is a growfs solution with the OP configuration assuming he is able to back-up slice 7 350 MB of data on a removable media (eg. a CD or a USB drive). The "no growfs on /" limitation can easily be overcome by booting on a Solaris installation media or Live CD.
s7 being more than likely contiguous to s0, both of these partitions can be resized to suit the needs and growfs used to enlarge the root filesystem.

Another option (although not a pleasant one):
dump the contents of /export/home onto a tape or CD or DVD
Record the results of

Code:

du -sh /opt

Record the results of

Code:

du -sh /var

Insert bootable Solaris CD

Code:

init 0
boot -s cdrom
format

Delete slice 7
Make 3 new slices - one for /opt, one for /var and one for /export/home (stick with slice 7 to avoid confusion)

Code:

mkdir /tmpopt /tmpvar
mount /dev/dsk/c0t0d0s0 /mnt
mount /dev/dsk/c0t0d0s(x) /tmpopt  ###pick a number between 1 and 6 that is not being used and is not 2
mount /dev/dsk/c0t0d0s(y) /tmpvar  ###pick a number between 1 and 6 that is not being used and is not 2 and not the number above

copy the contents of /mnt/opt into /tmpopt, copy the contents of /mnt/var into /tmpvar

**** Take care when copying the contents - there are several options that work well, and several that don't. Make sure that you are VERY aware of pathing when cloning these two directories. ****

modify /etc/vfstab to mount /dev/dsk/c0t0d0sx to /opt and /dev/dsk/c0t0d0sy to /var
Reboot

If the system behaves as expected, reboot from the Solaris CD into single user mode again. Mount /dev/dsk/c0t0t0s0 /mnt.
Delete the contents of /mnt/var and /mnt/opt

Reboot and enjoy
