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.
