Update 00:30:

All shares coming back online now. My sincerest apologies for the delay. And good night to all.

Update 22:40: We have run into hardware problems with one of the backends. The shares remain offline as we continue to diagnose it. A further update will be posted as soon as possible.

On Wednesday, 02 XII 2020, between 18:00 and 20:00, access to
igp-data shares will be interrupted for scheduled maintenance.
The shares need to be taken entirely offline for a network upgrade.
At the same time we will be adding more space to the underlying SAN.
This affects all shares on the igp-data storage gateway (ggl, pf and gsg).

Thank you for your patience, and kindest regards.

Update 23:50: we ran into severe problems and the migration took longer than expected. Everything is back online now. Sorry we're late.

Planned maintenance will be taking place on all shared-storage front-end servers on Thursday, August 6th, starting at 17:00. The service will be down for approximately 2-3 hours. This post will be updated as soon as work is completed, were we to finish earlier than expected. We will be upgrading the network switch and replacing hardware in several machines.

All group shares will be affected, i.e. group-data, IPA, IGP and Galaxy. Only the home and backup servers will be accessible during this time.

For emergency cases, there will be read-only access to last night’s backup as described here.

Update 18:15 group-data is back!

Planned maintenance will be taking place on our group-data.phys.ethz.ch server on Friday, June 19, starting at 17:00. The service will be down for approximately 2 hours. We will be replacing the network interface card to improve service stability.

All group shares will be affected except IPA, IGP and Galaxy.

For emergency cases, there will be read-only access to last night’s backup as described here.

On Monday morning we found out that large incoming mails (1 MBytes or larger) were dropped without leaving any error messages in our log files. These mails were lost between Thursday (Jan 9) evening 18:27 and Monday (Jan 13) morning 11:06. Some indicators (i.e. spam filter rules for this case) lead us to estimate the number of about 560 broken local deliveries to about 300 unique recipients.

If you expected e-mails with attachments close to 1 MB or larger within this time frame there is a high likelihood that they got lost. The only information we still have about these mails are sender, recipient and arrival date and time. If you were one of these recipients, please contact the sender to send it again.

You can check on this web page if mails you should have received were lost. You'll have to log in with your D-PHYS account and will see sender (or mailing list) of and time when the lost mail arrived. Additionally we'll inform all affected recipients individually, too.

The problem occured after one of the software updates on Thursday which brought stricter code checking, and is solved since Monday morning 11:06.

The issue was caused by a long standing and subtle programming error in the check which prevents bigger mails from being inspected closely by the main spam filter for performance reasons. It was only triggered upon local mail delivery, so mails sent from D-PHYS to outside D-PHYS were not affected. E-mails to D-PHYS mailing lists (or other mailing lists) with archive should be available in the according mailing list archives.

We're truly sorry for any inconvenience this may have caused and have already taken measures so that similar issues won't result in mail loss from now on.

Update: it happens to the best of us: Gmail for iOS bug might cause data loss

We updated the hardware of 5 computers in the student computer room HPV F 7.1. With 4 GB of RAM and 3.0 Ghz processor from AMD they now have much more performance than the older ones. For identification, we have marked them with a blue label. These computers are available for public use within the usage policy while they're not being used for exercises.
