Apparently an old wives tale, she tells me.
Woke up this morning to a barrage of emails that OOF is not displaying pages. Opps. Poxy primary DB server had run out of disk space, and shut itself down to protect itself. Quick fix - allocate ext4 reserved amount, start it up so it works, then in background allocate more physical disk space, and reset ext4 reserved back to 5%.
Just before midday, whilst on the phone, everything goes quiet. *Everything*. Silence. Its amazing how used you get to the fans. UPS went offline, knocking out all 3 physical servers, switches, router, modems, phones, the lot. Bloody Opps

. Pop the old (shagged) batteries back in, just to get UPS started, and slowing bring up the hypervisors and VMs. Unsurprisingly, the 2 OOF database servers disagreed, so had to break the sync and set it back up, which takes an age, as MariaDB needs a full dump of the master copy.
Get most of the stuff up, so now my email starts working, email from big bro (who is on holibobs), his website has died. FFS

. Turns out to be *exactly* the same issue as what happened to OOF overnight, the primary DB server ran out of disk space. Whats the chances of that

He's hoping the year improves.
