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 “gpart list”, but they have “(null)" labels, as do their one partitions)
So, "import -d /dev/gpt” doesn’t find anything (because none of tank’s disks are there), and “import -d /dev/diskid” finds the same as it configured automatically, with ada1p4 and the two diskid’s. 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 “ada1p4” “d0p1” and “d1p1”. 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 0x62 Aug 11 01:20 /dev/ada0p3
crw-r----- 1 root operator 0x64 Aug 11 01:20 /dev/ada1
crw-r----- 1 root operator 0x6b Aug 11 01:20 /dev/ada1p1
crw-r----- 1 root operator 0x6c Aug 11 01:20 /dev/ada1p2
crw-r----- 1 root operator 0x6d Aug 11 01:20 /dev/ada1p3
crw-r----- 1 root operator 0x6e Aug 11 01:20 /dev/ada1p4
crw-r----- 1 root operator 0x65 Aug 11 01:20 /dev/da0
crw-r----- 1 root operator 0x70 Aug 11 23:20 /dev/da0p1
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’d think it would work, but, both “zpool import” and “zpool import -d /dev” both show tank as:
tank ONLINE
raidz1-0 ONLINE
ada1p4 ONLINE
diskid/DISK-WOL240261932p1 ONLINE
diskid/DISK-WOL240261922p1 ONLINE
Let me know if there’s 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’s mostly just informational at the moment.
Thanks…
