Symptoms
When you attempt to create a third software volume (slot) on a BIG-IP device, a 'disk full' error occurs:
HD1.3
BIG-IP
16.1.0
0.0.1481 no
failed (Disk full (volume group). See SOL#10636) yes
Impact
Installation to the third volume fails with a disk full error.
Conditions
-- Using iSeries platforms.
-- Attempt to install certain BIG-IP software versions on a third installation volume on a BIG-IP device.
Workaround
You can work around this issue by reducing the dat.appdata volume size. For instructions on how to do so, see K74200262: Reducing the size of the appdata volume with the lvreduce utility ::

Notes
======
-- Depending on which software versions exist, installation might succeed, or it might fail; e.g., these existing configuration succeed:
- v12.1.2 + v16.0.0 + v16.1.0
- v15.1.3 + v16.0.0 + v16.1.0
-- Even though v15.1.3 and 16.0.x have a smaller footprint, if there are two 16.1.0 installation locations, the third volume installation/upgrade does not succeed.
-- You can avoid the issue completely formatting the system
while you install (i.e., using 'image2disk --format=volumes').
Important: Make sure to back up your configuration before formatting the system.
Fix Information
Beginning in BIG-IP 16.1.0, the disk layout created when reformatting (i.e., using 'image2disk --format=volumes') has slightly decreased the size of the 'appdata' volume to allow for three software volumes.
Behavior Change
Beginning in BIG-IP 16.1.0, the disk layout created when reformatting (i.e., using 'image2disk --format=volumes') has slightly decreased the size of the 'appdata' volume to allow for three software volumes.
