Failed Hotfix update

Hi,

Just tried to apply Hotfix-BIGIP-13.0.0.2.0.1671-HF2 to existing 13.0.0.0.0.1645 volume - HD1.3. Result was failed with info below:

tail -f /var/log/liveinstall.log
info: /: Not enough free space
info:   268609536 bytes required
info:   226794496 bytes available
info: /var/local/ucs/config.ucs: Not enough free disk space to install!
info: Operation aborted.
info: >----
info: Removing boot loader reference

Terminal error: UCS application failed; unknown cause.
*** Live install end at 2017/05/22 09:39:59: failed (return code 2) ***

So I mounted /var from HD1.3 with mount -t ext3 /dev/mapper/vg--db--sda-set.3._var /mnt/tmp_root

Then I did df -h with result:

Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/vg--db--sda-set.3._var 3.0G  1.3G  1.6G  45% /mnt/tmp_root

Seems like there is plenty of space on /var so why the error?

Is there a way to increase size of directories of not active volume (like when using tmsh modify /sys disk directory /shared new-size for active volume)?

Side question

I did fresh hotfix install on new volume HD1.4, then used GUI Boot Locations to select it with Install Configuration: No

After reboot my whole config was copied to new volume - why so?

My db.liveinstall are like that (I doubt I was changing them from defaults)

tmsh list sys db liveinstall.* one-line
sys db liveinstall.checksig { value "disable" }
sys db liveinstall.longmode { value "enable" }
sys db liveinstall.moveconfig { value "enable" }
sys db liveinstall.movelicense { value "enable" }
sys db liveinstall.packageset { value "default" }
sys db liveinstall.saveconfig { value "enable" }
sys db liveinstall.savelicense { value "enable" }
