Okay. I thought I would try this last bit. However, only the first =
two disks (still ada0 and ada1) list partitions in /dev/gpt, because I =
just used the entirety of the other two disks I guess. And, only the =
other two disks have shown up in /dev/diskid. (nb, later research shows =
the other disks when I run =E2=80=9Cgpart list=E2=80=9D, but they have =
=E2=80=9C(null)" labels, as do their one partitions)
So, "import -d /dev/gpt=E2=80=9D doesn=E2=80=99t find anything =
(because none of tank=E2=80=99s disks are there), and =E2=80=9Cimport -d =
/dev/diskid=E2=80=9D finds the same as it configured automatically, with =
ada1p4 and the two diskid=E2=80=99s. Only /dev/gptid does what you =
describe above, where it lists all three by gptid, but I would prefer =
not to do that atm.
I was hoping to get =E2=80=9Cada1p4=E2=80=9D =E2=80=9Cd0p1=E2=80=9D =
and =E2=80=9Cd1p1=E2=80=9D. If I ls /dev, I see:
# ls -l /dev/ada* /dev/da*
crw-r----- 1 root operator 0x5f Aug 11 01:20 /dev/ada0
crw-r----- 1 root operator 0x60 Aug 11 01:20 /dev/ada0p1
crw-r----- 1 root operator 0x61 Aug 11 01:20 /dev/ada0p2

crw-r----- 1 root operator 0x66 Aug 11 01:20 /dev/da1
crw-r----- 1 root operator 0x76 Aug 11 23:20 /dev/da1p1
So I=E2=80=99d think it would work, but, both =E2=80=9Czpool import=E2=80=
=9D and =E2=80=9Czpool import -d /dev=E2=80=9D both show tank as:
tank ONLINE
raidz1-0 ONLINE
ada1p4 ONLINE
diskid/DISK-WOL240261932p1 ONLINE
diskid/DISK-WOL240261922p1 ONLINE
Let me know if there=E2=80=99s something else I can try. Otherwise, I =
may just try putting gpt labels on the other partitions. But, I have =
more controller swapping soon, so it=E2=80=99s mostly just informational =
at the moment.
Thanks=E2=80=A6
