Storage Issues, 6pm Friday Feb 24

by

The Department’s fileserver is having operational issues. Staff are investigating. The Network Appliance servers for EECS Home directories, Project space and some Instructional storage have been intermittently affected. This may affect other services which depend on the storage, e.g. personal web pages.

OSX using NFSv4 caused the panic . I have disabled NFSv4 on napinst which was the only one using it. But it affected other nodes.

napinst and napcluster were not available during the downtime but naproj was ok. naphome I believe was ok too.

Mounts that are stuck will mean a client system reboot, if umount is not possible.

There will be a patch OS version coming out soon, and I can upgrade the netapp when it does, and renable NFSv4.

Until then all users on napinst clients will have to change NFS vers=4 to vers=3 if they are explicitly configured.
