On Jan 5, after weeks of thorough planning and rigorous testing, we performed a migration of the home directories and group shares to our new SAN system. Soon afterwards, the first phone calls started coming in. The initial problem was very exotic and affected very few people (that’s why we had no chance to detect it during the testing period), but the action we took to address it unfortunately caused a cascade of consecutive faults that led to the instabilities you had to endure for one week now and for which we are truly sorry. We now know how to fix the underlying problem, but we cannot operate on the running server. That’s why we have to schedule an
emergency file server migration on Sat, Jan 14, starting at 07:00 and lasting well into the afternoon probably.
During this time, you will not have access to your home or group directories, and also email will only work intermittently. Please stop all running jobs and log out before Saturday morning.
We apologize for the suboptimal performance since Jan 5. You have every right to expect better, but this caught us completely off guard. Thank you for your understanding.
Update, Sat 14:15: mounts and email are up and running again. The problem on 32bit machines still persists, but we have an idea how to fix it on Monday.
Update Fri 20.01: we (hence you) are still suffering from severe stability problems on the file server. We are very hard at work and now have a plan that we really really hope will solve the problems. There will be another migration sometime next week. We’re truly sorry for the inconvenience you have to endure.
