HolyLFS holylfs cycling

1/28: Holylfs instability is due to the fact that the new Cannon cluster has outstripped the ability of holylfs to keep up with jobs. We are actively working on a replacement for this system but it will not be available until later this year. In the meantime we ask that users on holylfs not run production jobs on holylfs and only use it for long term storage. Instead please use our scratch filesystems for production jobs (see upcoming maintenance email for more information on this). If you need assistance with rearchitecting your workflow please contact us.

Update 2:40pm: General high load on holylfs is causing instability. We are looking into this further

11:46am: looking into performance issues on holylfs

10:11am: holylfs has been rebooted 9:52am: holylfs is being rebooted for the next 15 minutes due to stuck jobs
