We have an older file server (running Gentoo of all things) that recently suffered a storage controller failure. The parts were replaced and everything is back online except one item, probably the most important: the ESXi mount point.

The former sysadmin, while brilliant, never kept notes for any changes. There's nothing in FSTAB or CRONTAB or any 'normal' place to create mounts. Running zfs list shows all the ZFS mount names, but has a blank for the mount point. My coworker and I are poring through log files trying to find any indication of historical mounts, but there's nothing. This is connected to the open-source licensed compute server via infiniband, but unsure whether it's shared via NFS, iSCSI, or what. Like I said, no notes to work from.
