Re: [bitfolk] Further emergency maintenance needed for node "president"

Ever since president was rebooted last night it has suffered from poor IO performance: http://tools.bitfolk.com/cacti/graph_2639.html I've been working through the night to try to find the root cause, but am not having much luck. There's no higher demands being made of the node compared to earlier on: http://tools.bitfolk.com/cacti/graph_2640.html and as far as I can see, the RAID controller is happy with every disk and with its battery and write cache. At the moment I am running a reinitialise on the RAID array which is going to take a couple of hours. Once that completes, if it hasn't improved matters then I will be rebooting the node again. I have some ideas of a couple of settings that should be changed, that require a reboot, although I can't explain why their current setting would make any difference now compared to the last ~250 days. It is a bit of a shot in the dark admittedly. If that doesn't work, I shall be on my way to the datacentre to replace RAID controller from spares. I'm afraid it looks like this is going to cut well into UK working hours today. Please accept my apologies for the disruption; it has been completely unexpected.
