Sadly, no. I looked through my buffers and don=E2=80=99t. Have a few =
df=E2=80=99s, but other than a showing a system with it=E2=80=99s few =
filesystem including the 40T zfs one, it doesn=E2=80=99t 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

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=E2=80=A6.
