HELP, ZFS pool not found

[LAYGO]

My original install on an older thumbdrive crapped out, I luckily got it to boot 1 more time to get a config backup. The original install was 8.0.2-Release. I'm now on 8.0.3-Release-P1. I don't think that would cause the pool not to be found, but I couldn't find the archived versions to try from 8.0.2.

So, I had pulled my drives out while trying to see if I could get the system to boot because I didn't want to accidentally nuke the data or anything (still a noob to all this). Once I got it to actually boot, I restored the config, but didn't put in the drives, when it booted it said "pool not found". Ah, so I put the drives in, rebooted, still pool not found. Rebooted once more, reloaded the config, rebooted during the config, still pool not found. I tried auto import from the GUI, doesn't show anything. I'm almost afraid I should've exported before doing all this, but I'm not sure what the whole ZFS import/export process is. I'm learning as I'm going.

When I tried to search on "pool not found" using quotes, the forum thinks its "pool -found". :( Where does that log show where the pool is?

[ProtoSD]

Try doing a "gpart show" and posting the results. Don't freak out and do anything yet, your pool is probably fine. Sometimes the device names change and the GUI/database thinks they're called something else and won't/can't import them. Post those results and me or someone here can help you figure out what's happening.

I should have a 6tb pool, RAIDZ1 (4x2tb).

So, am I screwed or what? I have no idea how to proceed w/o losing all of my data! :(

Wait a cotton picking moment. Really reading the dmesg, it's only picking up 2 of the 4 drives. WTF? This is a Proliant MicroServer N40L, so there's no cabling as it's a back plane & drives are in trays that slide in & latch. Nothing was wrong with my RAID when the thumb drive w/the OS on it crapped out. WTF?!?!? :(

 

[LAYGO]

So, checking the BIOS, it's showing drives 2 & 3, not 0 & 1. I swapped drives 1 & 3, still see drives 2 & 3. Might be something going on internally with the cabling. Will need to crack the case. :(

 

[Brand]

I have no idea how to proceed w/o losing all of my data!

Do you not have a current backup of your data?

 

[LAYGO]

Do you not have a current backup of your data?

Of course I do . . . OFFSITE! I just don't have it here, but I'm thinking it's a bigger issue with the back plane seeing only 2 of the 4 drives. Dunno why.

 

[William Grzybowski]

Either way, "zpool import" should show a pool in UNAVAIL state with only 2 disks ONLINE

 

[LAYGO]

P H E W !

I think it was just a loose cable, but I hadn't been able to open her up until now. Reseated all the power, all the drives, and the mobo's mini-sas, booted it, all 4 drives showed. I'm able to view the files as well. Need to reconfigure Transmission/Serviio again . . .
