CLI hangs when entering VDOM - WebUI won't load at all

[ergotherego]

200D HA cluster running 5.6.5. Traffic is passing fine, first noticed issue when FMG wouldn't push changes down. Get into CLI and its fine while in global mode, but once you try to enter a VDOM the CLI just hangs.

WebUI lets you login and get past all the prompts, but then won't load the page.

CPU is 100% idle, memory usage is 45%.

Anyone have any ideas?

Looks like its due to disk errors. Was able to find some events in FAZ for it:
