Title: Another outage very soon
Post by: TheBoy on 29 November 2013, 15:35:24
I need to put some new bits in, to keep the hamster going...

Mr Courier has just delivered the bits, hence a bit later in day than I wanted to :(

Hmmm, TB ponders if the stuff will be hot plug...   ...whats the worse that can happen?

TB realises he's being a 'tard. Some bits may be hot plug, but some certainly aren't.

So we're going down at 4pm

T'will be quite poor for a while, as the disks thrash themselves to within an inch of their lives, as the controller changes the RAID configuration in the background....

Array transform priority knocked up to max now, which *may* have a performance hit

Seems good now, in fact better than ever :y

Just a little reboot of the main OOF machine needed, to allow a change to occur

Thought the outage was just when I clicked on this thread - had been ok up to then, if a little slow ???

Pub time. If it falls over tonight, write to your MP.

The controller's cache is disabled during the disk transformation, so it will be very spikey.

Backups disabled for tonight, and all non essential services shut down until the transformation completes.

17% through the RAID transformation. Its getting there.

Once the transformation is complete, the cache should reenable itself, improving write latency, speeding things up a bit (or more accurately, being able to dampen out the performance lags). Cache is needed for transformation, so cannot be used until that process completes.

So I'm guessing a hard drive failure, replaced with a larger drive ?? thus requiring a Raid transformation ??

Odd that you had no pre-failure warning from the drive controller given the problems you reported ...

however, many thanks for all your efforts on our behalf  :y :y :y

A hard drive failure would have been an easy spot. This is an attempt to improve the rather poor read latency we've been suffering of the that past couple of weeks, at the expense of write performance  :-X
