Does TrueNas record/report why a drive was dropped/degraded from a zpool.

[Doug183]

I have 10 drives (18TB each) setup as one zdev as RaidZ2 in one pool.
Storinator metal 45 drive capacity.
Supermicro X9SCL/X9SCM
64 Gigs ECC Memory
Intel(R) Xeon(R) Bronze 3204 CPU @ 1.90GHz
2 X LSI 9305 24i cards flashed IT mode firmware 13.xxx
Intel 510 10GB pcie NIC
TrueNAS-12.0-U8

Problem:
When I check the zpool, sometimes it reports that its degraded. I am trying to trouble shoot if this a computer problem or a drive problem. (I have reasons to believe its a computer issue, but can't tell.). So...

Does TrueNAS record the details "why" it degraded the zpool. If so, where and how can See that info?

dmesg

or /var/log/messages or one of the older archive files (like messages.0.bz2 or other numbers) files held there if it was before your last boot.
