Due to physical rearrangements in the server room the tape robot hosting /migrate and /bcmhsm will be unavailable today after 12:00 for several hours. Updates will be posted here.

Update 2017-09-11:

Uni Computing is experiencing troubles with the backend holding /migrate and /bcmhsm and it is unknown yet when this will be fixed. As these file systems were supposed to be already decommissioned earlier this year in June, we will not mount those back in ordinary place even after the file systems are healthy. However, we will finish transfer of IMR/HI files as it was agreed as soon as the filesystem is healthy. We will issue a separate update for this.
Other users  than IMR/HI needing files from those file systems are advised to contact Uni Computing helpdesk at trouble@computing.uni.no.

On Friday, 25th of August maintenance on electric lines in the server room will be carried out. Therefore Hexagon must be switched off.  All related file systems (/work, /work-common) will be also off.

The maintenance will start at 07:00 and according to the plan should last until 13:00 o'clock.

During this time work-common will not be available on  Grunch .

Update:
  • 25.08.2017 07:00: Maintenance has started.
  • 25.08.2017 12:50: Storage controller issues are delaying startup of the machine. We are working on the fix.
  • 25.08.2017 15:05: Storage controller issues were remediated. Some disks are rebuilding for /work-common filesystem, thus performance impact might be expected for a couple of days.
  • 25.08.2017 15:20: Hexagon is up again.

Length of downtime is up to 8 hours for /work-common and up to 2 days for /work.
