    This incident has been resolved by draining and rebooting any nodes with stuck mounts.

    Mounts to Holyoke Isilon (specifically /n/sw) are broken on numerous nodes across the cluster. We have a check rolling out to find these nodes so we can remediate them individually. Until remediated the cluster will be in a degraded state. Running jobs may randomly die or fail as they hit nodes that have stale mounts.

    It will be risky to run jobs for the next hour and then, after that point, the cluster will have a large number of nodes closed waiting for them to drain so we can reboot them and fix the mounts.

    At this time we are unaware of any holy-isilon problems other than the effect this had on cluster nodes/running jobs. We will update should we identify any data storage concerns.

    A network issue affecting storage critical to the cluster is It's causing instability. The cluster is currently in a degraded state as a result. We are looking into the problem. Updates to follow..
