ISG News has posted a new item, 'groupdata downtime'

Upcoming downtime: XFSv5 on groupdata network shares There will be a larger maitainance downtime for all D-PHYS grouphares. Other shares like Web, IPA, ... are not affected. The downtime is scheduled for:

Saturday, January 3rd 2026 20:00 -- Sunday, January 4th 2026 10:00

You will not be able to access any shares on groupdata during this time. Afterwards everything will just work as before. If this will disrupt any essential operation, let us know asap! There will be another reminder closer to the downtime. Technical background: We need to upgrade the XFS filesystem metadata. This cannot be done in place, so we have to backup, reformat and restore all shares. We need to sync roughly 180TB so it will just take some time.
