    XFS journal recovery has completed, and kou_lab is remounted. The lab should verify the filesystem and any data that may have been written after 11:00 AM on 8/11/26 (Tuesday).

    In simple terms, too many open files caused the server to become unresponsive, which triggered an automatic reset. After the reboot, XFS required an extended recovery period before the filesystem could be mounted again.

    This does not mean the lab caused the issue. The file descriptor limit is a system-wide kernel resource shared by all filesystems and workloads on the server, so any share or process running a large job could have contributed. kou_lab was essentially collateral damage from machine-wide resource exhaustion, a “noisy neighbor” effect on a shared system.
