During the summer we started getting tight on storage availability. It seems that usage on our home directory areas constantly increases – people never delete stuff (me included!). We were running most of our stuff through our Veritas Cluster from a pair of Sun 3511 arrays and a single 3510 array. Between them (taking mirroring in to account) we had …
Once again we have a new look Computer Science website, but this time I’ve done most of the work to get us there.
How to get the Eduroam wireless network at the University of Kent to work on FreeBSD.
For many years now (since before I started working at the University) we’ve been using University of Washington’s IMAP and POP daemons. They worked well, and (through an old bit of unsupported code) also allowed our MH users to access their email. As time went on people wanted to do more than UW’s software could offer. Things like nested folders, …
Today we saw a strange problem on our Solaris hosts that NFS mount VxFS filestore from our Veritas cluster. The users were seeing “Disc quota exceeded” messages, whilst the quota command wasn’t showing they’d hit their limit. After some digging on the cluster node we found the following error message: Sep 12 11:04:33 bes vxfs: [ID 702911 kern.warning] WARNING: msgcnt …
Since launching CSProjects last year we’ve had nearly 80 projects set up on it. I’m pleased with the success it’s had so far, but I’m still surprised by people not knowning about it. Recently I’ve been trying to do more to publicise it, with some success. Over the past couple of weeks I’ve spent some time sorting out the upgrade …
I’ve made a couple of posts lately about the problems we’ve been having with one of our Sun 3511 disk arrays. Sun got back to me today with what they thought the problem was. Here’s the gory detail (slightly truncated to fit this blog post): * SES Ch Id Chassis Vendor/Product ID       Rev PLD ————————————————-  2 28 092131 SUN StorEdge …
After all the fun the other day I was hoping for some time to work on other stuff this week. By the end of the weekend the array had finishing syncing and I’d remirrored all the volumes back on to it. It was all ticking over nicely, until this morning… Unrecoverable Controller Error Encountered ! Resetting Controller ! After which …
“Any idea WTF is going on?” is what I read on my phone as I stumbled out of bed this morning. It was from one of my colleagues who, for some reason I can’t understand, seems to like getting in to work at a ridiculous hour in the morning. Still half asleep I plodded through to my desk and sat …
