Login2 was rebooted due to the hardware errors with the Ethernet card, rendering login2 unavailable from the network. The problem should be resolved now.
Hardware
Grunch: down
Both operating system disks failed in a short timeframe in Grunch making the system unoperational. We are trying to recover from the failure ASAP.
Update 14:00_06.10.2017: grunch server is up again. both os disks are replaced and grunch server are reinstalled.
/migrate and /bcmhsm offline on September 4th
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.
Hexagon: IMR volumes offline
The network equipment connecting Hexagon and IMR has to be changed and needs a maximum two hours downtime.
Therefore IMR volumes will be unmounted on Tuesday, 29th of August from 09:00 AM for approximately two hours. By that time, please stop all your processes on Hexagon which are using the IMR volumes.
