NetApp fileserver downtime in preparation for upgrade – Phase I: Monday, June 10, 6-8pm

June 3, 2019 by Pathma Venasithamby

NetApp filers are due for their 4 year refresh cycle. Work on this has commenced, with new NetApp hardware on site. New filers are going to be added and data migration will occur some weeks down the road. While most of the work will be non-disruptive, some elements will be disruptive.

The first of this will happen on 10th June Monday, and the scheduled downtime will be from 6-8pm, to incorporate some network changes. All NFS and CIFS access to the filer (home and project storage) will be down during that time.

Fileserver maintenance 10apr18

April 10, 2018 by Pathma Venasithamby

This should be mainly non disruptive, but be forewarned in case of mount issues.

Any CIFs shares will experience a disconnect but upon reconnect it should reconnect to the the other HA node. If someone is doing a copy over a share they will have to restart that.

Fileserver maintenance 30th Jan

January 30, 2018 by Pathma Venasithamby

Due to the power failures on 20th Dec, the department fileservice has suffered some damage, and there is a non functional management interface. This needs to be repaired or replaced. This should *not* be disruptive to users, as per Netapp. But it does involves reseating or replacing a motherboard on one of the nodes, so please be forewarned that one of the clusters will not be running in HA mode during the replacement.

Fileserver maintenance

February 20, 2017 by Pathma Venasithamby

Upgrading NetaApp OS 11am-2pm on Presidents Day holiday 20th February

Department fileservice may experience some short interruptions during the maintenance window, approximately 11am until 2pm.

Many services that rely on access to department fileservice (home directories, webservice, repo service, NFS and CIFS mounts, etc) may notice some performance issues during this period.

We expect most, if not all, clients to recover automatically once work is complete. This news item will be updated to indicate when the maintenance is completed.

Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.

Many services that rely on access to department fileservice (home directories, webservice, repo service, etc), will either be offline or will fail to work during this window. All NFS and CIFS mounts will be affected.

We expect most, if not all, clients to recover automatically once the fileservers are back online. This news item will be updated to indicate when the maintenance is completed.

Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.
