Cyclone and Grunch immediate Downtime

Dear Cyclone and Grunch server users:

We discovered possible filesystem corruption on /shared Lustre filesystem today. To eliminate data loss, we have to take down /shared filesystem and run filesystem check immediately to make sure that the filesystem is not corrupted.

We plan to start at 12:50 today.

User login to Cyclone and Grunch will be locked during the process, and all NFS and smb exports will be terminated.

We are sorry for any inconvenience this may have caused, and we will keep you updated on this page.

Please contact us via if you have any further questions.

Update 14:00 : The filesystem check is running.

Update 20:50 : The filesystem check is still running, we will continue tomorrow.
Update 21.01.2020_13:40:  /shared filesystem is back online, and user access for cyclone and grunch is enabled.  NFS and SMB is started.  There might be some data loss under /shared/projects/gfi/ folder, make sure that you go through your important files and report back if you missing some files. So far, we identified one file loss from this folder which we will make direct contact with the owner of the file.
