Our unix login server, login.eecs, is temporarily offline. We will be building a new virtual machine to replace it, and hope to have it in service by tomorrow.

[Read more…] about April IRIS Server PatchingNetApp Fileserver Migration, Saturday April 18, 2026
We are scheduling a NetApp migration to new hardware, from 8am to Noon 5pm-9pm on Saturday, April 18, 2026.
All Home directories and Project shares (CIFS/SMB and NFS) will experience disconnection during the migration that may cause data loss on active, open files. Please close your open files and save them before Friday morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive. Because this is a migration to new hardware, clients may experience a series of short (minutes-long) disconnections as volumes complete their migration steps.
When maintenance is completed, NFS clients may automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.
