Home Directory Storage

NetApp Fileserver Migration, Saturday April 18, 2026

April 3, 2026 by Lars Rohrbach

We are scheduling a NetApp migration to new hardware, from 8am to Noon 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.

Corrected exports for EECS NetApp file server

December 17, 2025 by Lars Rohrbach

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

November 12, 2025 by Lars Rohrbach

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.

All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update 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.

Soda Hall 2nd Floor Power Outage on March 26, 2025

March 14, 2025 by Lars Rohrbach

Following up on the work done during the June 13th Soda Hall power outage, we have a similar outage for the second floor of Soda Hall scheduled during Spring Break, to complete (hopefully!) a circuit breaker replacement. As with the last outage, electrical power to the Soda Hall second floor will be down during much of the day on Wednesday, March 26, 2025. Critical systems will be down from about 6am until perhaps 5pm.

Of primary note is that the department NetApp fileservers will be down, so any systems that depend on HOME or PROJECT storage will be shutdown or nonfunctional. Services that will be unavailable during the maintenance period include: department webservice (including people.eecs, www2.eecs and all other IRIS-hosted web sites), IRIS account & network forms, login servers (login.eecs, login-mfa.eecs, winterm.eecs), print server print.eecs, and outgoing SMTP server smtp.eecs.

Any systems that remain powered-on but make use of HOME or PROJECT storage may become unresponsive during this time. Rebooting after maintenance is completed is usually recommended.

Services that will remain online and available include: DHCP, EECS Active Directory, EECS LDAP, wired networking, DNS (cronus.eecs), and maillists (lists.eecs), and the main department website eecs.berkeley.edu.
