It involves the storage metadata controllers, so we need to take down all servers and workstations directly connected to the Stornext system:
login.astro.uio.no
algol, dubhe, electra, electra2, enir, euclid21, karbana, mimosa2, shaula
achernar, aramec, nekkar, papsukal
owl1-owl28
beehive26 - beehive28
charybdis1 - charybdis3, proxima
All OS-X Mac Pro workstations
The other workstations will be up, but access to the StorNext disks will hang when the NFS-server is down.
I will also use the opportunity to install a StorNext upgrade that was just released.
I will start shutting down Saturday morning, and expect to have everything back up later in the day (if I don’t run into unforseen problems).
Status:
06:30 Shutdown of clients
09:00 Shutdown of NFS and login servers
10:35 StorNext upgrade to version 5.4.0.1 of metadata controllers complete
12:00 NFS server upgraded to 5.4.0.1 and up. Seems to be stable now.
15:30 login.uio.no ready. All linux machines upgraded to 5.4.0.1
15:30 Mac OS-X workstations coming up. We will upgrade firmware, so wait with login until we post here that they are read
17:14 Mac firmware upgrades done (except black and senshu). All macs up.
17:20 Done.
