2.4 Virtualization Hosts Crash if a Storage is Shut Down (Bug ID 13557337)

If a storage host is shut down (or crashes) and the associated Oracle Cluster File System version 2 (OCFS2) file systems are still mounted on the virtualization hosts, the virtualization hosts crash.

If you need to reboot a storage host, enable maintenance mode for the storage first, see Storage Maintenance in the Oracle Virtual Desktop Infrastructure Administrator's Guide. This enables Oracle VDI to unmount the OCFS2 file systems. Once the storage is in maintenance mode, it can be rebooted.

The problem affects VirtualBox hosts on Oracle Linux platforms if you use either Sun ZFS storage or iSCSI storage.
