Disk space allocation varies from release to release. For example, on my v10.2.4 box, I have:
Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg--db--sda-set.2.root 248M 130M 106M 56% / /dev/mapper/vg--db--sda-set.2._usr 1.4G 1.1G 244M 82% /usr
On a v11.2/3 box, I have:
Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg--db--sda-set.3.root 287M 191M 82M 70% / /dev/mapper/vg--db--sda-set.3._usr 2.0G 1.6G 380M 81% /usr
I wonder if sizes have changed/increased in v11.4 and v11.5?
I read it somewhere that BIG-IP will create a new volume the same size as the current boot volume. If that is the case, one can only take advantage of the increased size provided by a new release by a total re-install.
Can somebody please confirm / deny if this is the case?
