For the Read-Only problem, a simple reboot suffices. But I made sure to fire an angry email to the Customer Support, telling them in no uncertain terms that the next time they want to do something re: their storage, they contact me first. So, when the time comes for then to do some storage management things, they tell me exactly at what time. I scheduled the VMs to shut down at the agreed time, and turn them back on as soon as they text me that their maintenance had finished. Only one VM I left on, the "gatewall" VM. And every single time the gatewall VM detected that something is being done on the storage level, and changed to a Read-Only mode. I consider myself lucky that when the 'problem' manifested itself, the VMs are not yet in Production. And no corruption happened. (PS: Strangely enough, the RO switch happens only on Gentoo VMs; the FreeBSD VMs and Debian VMs are unaffected. Maybe because I've pared down each and every Gentoo VM to their bare minimum, so they are much more responsive) Rgds, --
