How can I recover my ZFS pool, which suddenly went offline and reports that it was "last used by another system"?

tl;dr: I am running a FreeBSD 11.2 NAS server with ZFS on a server with 16GB ECC memory. I've discovered that my main pool has disappeared. ZFS can see the pool, but reports fault ZFS-8000-EY and that it cannot import 'tank': pool may be in use…

ZFS on single virtual disk

How do companies manage large file servers (e.g. 17 TB) and their related backups on a very tight-budget? Is it ok to use ZFS (or BTRFS) on a single virtual disk for its copy-on-write nature to eliminate the need for fsck? (i.e. not for its RAID,…

Procedure/Effects of hot-removing a mirrored vdev disk
