Urgent NetApp Fileserver Downtime, Saturday July 8, 2023

July 6, 2023 by Lars Rohrbach

We will be scheduling an urgent 4 hour Maintenance to update our NetApp fileserver from 8am to 12pm on Saturday, July 8, 2023. This update must be done prior to installing Microsoft Updates on AD Domain Controllers scheduled for release on Jul 11^th to secure the Netapp and maintain future connectivity with Microsoft AD Domain connection for our CIFS/SMB Shares.

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 Saturday Morning. Services (e.g. webservice) that depend on this storage will also be down or unresponsive.

When maintenance is completed, NFS clients should 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.
