This process is about managing space on a ZFS pool (in this case, rpool) that is full.

A possible solution is to move a large swap file (over 8 GB) to another pool, thus freeing up space on rpool.

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2 (optional). Change into Solaris shell (in case you're directed to an unsupported shell)

un sh

Step 3. Get root privileges

sudo su -

Step 4. Create a new ZFS volume for the swap file (replace <pool_name> with the correct pool name)

zfs create -V 8G <pool_name>/swap

Step 5. Add the new swap (replace <pool_name> with the correct pool name)

swap -a /dev/zvol/dsk/<pool_name>/swap

Step 6. Check the path of the new swap

swap -l -h

Step 7. Open configuration file for the new swap

vi /etc/vfstab

Step 8. Replace the entry for the old swap file with the new

/dev/zvol/dsk/<pool_name>/swap

Replace the entry for the old swap file (/dev/zvol/dsk/rpool/swap) with the path to the new swap (/dev/zvol/dsk/<pool_name>/swap)

Step 9. Remove the old swap

/usr/sbin/swap -d /dev/zvol/dsk/rpool/swap

Step 10. Delete the old swap volume

zfs destroy rpool/swap
