We are aware that all IRIS services are currently down. More information will be forthcoming as it becomes available.

CIFS shares from Project/Home unavailable
Windows and MacOS systems use CIFS shares on our NetApp fileservers for home directories and project space. With the sunsetting of our EECS Active Directory, we are in the process of migrating our NetApp to the Campus Active Directory. In that process, we’ve run into some unexpected issues, and are working with campus IT staff to resolve them.
At this time, CIFS shares remain unavailable.
NFS shares, as typically used by Linux/Unix systems in EECS, are not affected.
We apologize for the service interruption. We will continue working with campus staff to restore CIFS service as soon as possible.
Investigating Windows mount issue with new fileserver
We have reports of problems with CIFS mounts of home directories and project shares from the new NetApp fileserver. CIFS is typically used by Windows or mobile clients. Staff are investigating and will report here as we learn more.
NFS mounts (typically unix/linux) are working as expected.

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.

A recent report of a discrepancy in our file server NFS exports helped us to discover an error in our NFS export policies. The error would allow shares with the default NFS export setting to be mounted on some systems within EECS networks that they were not intended to be exported to.
We have corrected the error, and audited our NFS export policies. If you discover any unexpected change to availability of your home directory or project space, please feel free to reach out to help@eecs.
NetApp Fileserver Maintenance, Friday November 28, 2025
We are scheduling a NetApp ONTAP upgrade, to apply a necessary update to our NetApp fileservers, from 8am to 12pm on Friday, November 28, 2025.
