Sadly, no.  I looked through my buffers and don’t.  Have a few df’s, but other than a showing a system with it’s few filesystem including the 40T zfs one, it doesn’t help.

Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/da0p2     3.5T    4.2G    3.2T     0%    /
devfs          1.0K    1.0K      0B   100%    /dev
/dev/da0p1     256M    1.7M    254M     1%    /boot/efi
/dev/ada1p1    445G     36K    423G     0%    /ssd/scratch
tank            49T    9.5T     40T    19%    /tank

I can say that the pool has three raidz vdevs in it, each with three devices.  3 4TB disks, 3 6TB disks, and 3 18TB disks.

Nope, that shows just a clean boot from when I rebooted the system yesterday.

Yeah.  Maybe that should be in the normal daily job if the system is using any ZFS volumes….
