Title: Still not running right
Post by: TheBoy on 23 November 2013, 17:26:20
Sorry for earlier...  ...and for what is still to come.

Its running like a sack of shite, needing 100% attention to keep it up, and will likley need another reboot this evening (full hypervisor restart, so a huge outage :()

Don't fret TB, we're all used to things not running right!!!  ::)  We're Omega owners after all!!!!  ;D

Thanks for your efforts, as I'm sure you had better things to do today!  :y :y :y

Thank you for all the effort you put in running the OOF server and the best of luck in quickly finding and fixing the problems.  :y :y :y :y

I can't see anything wrong with the bloody thing, yet clearly there is.

Trying to minimise disk activity across all the VMs so hopefully it will run through the weekend without falling over, and I'll take another look one evening in the week.

Some things that were noticed, but need resolving:
Array card firmware is out of date, with a controller lockup fix in the new firmware
Hypervisor is out of date
Lights Out controller firmware is out of date, security related, but not vulnerable.

All these need full hypervisor outages, which are long ones, as it takes a fair while for all the VMs to stop, and restart afterwards. Although, none of these I believe are the cause, as nothing has changed at hypervisor/hardware level.

Fast here. I'm on a crappy 3G connection too!

When its good, its very good. But all of a sudden, disk latency goes through the roof for no apparent reason, processes back up, it starts to swap, then its only a matter of time before it falls over.

It's probably tired, like a computer slows down and eventually stops. It's just had enough.

Needs one of those new Redberry Pi thingy's in there.  :-X

RPi doesn't have the legs to run the site, due to lack of memory and cpu grunt.

(thats a slight lie, it can run it with a fast Class 10 card, but is too slow to be useful once traffic ramps up)

Trouble is on a busy server once processes start stacking up, taking even more resources, it is on a path to nowhere.  :o :o :o :o

Indeed, Rods2, once a Linux server dives into swap due to a disk i/o loading, the system will die fairly quickly, and Linux has a god awful desire to swap before releasing buffers.

Trouble is, I'm not sure what is causing the i/o latency to spike for reasonably extended periods. Disk throughput seems to be about normal just as it starts (but drops off, obviously, during the problem period).

Across the hypervisor, our baseline latency on the HP Smart Array is single digit, but will spike to over 100ms for 15mins or more, which certainly kills all Linux VMs, as they swap rather than release disk buffers, compounding it (though the OOF main server swaps to SSD, so has less impact to hypervisor). The Windows and Solaris VMs cope better.

I think the problem lays at the hypervisor level, as I've halved the amount of ram that the OOF server is allocated, and it seems to be far more stable, with only one brief alert (a slow response) overnight. But nothing has changed at that level. Hardware has been up since the fire, no updates to firmware or hypervisor have taken place....
