Drive "UNAVAILABLE" -- but which one?

[Z300M]

zpool status

shows that one drive in one of my vdevs is "UNAVAILABLE" but does not tell me which one:

Code:

How do I find the Serial# of the unavailable drive?

 

[zambanini]

that is the reasson you label the drives before you deploy them.

right now you can write down all the serial numbers und take a look which drive is not within your last.
smartctl might help you, or the web frontend, show disks‎

All the drives are labeled with their Serial Numbers.
All show up in the GUI's View Disks.
smartctl -a /dev/daX shows all as "PASSED".

I made a script to map device name, GPTID and serial number that might interest you: https://forums.freenas.org/index.ph...s-hdd-cpu-temps-and-hdd-identification.27365/

The simple command

glabel status

tells me that as well -- but it tells me the current gptid label for each disk; BUT

zpool status

tells me the former gptid label for the unavailable disk. None of the disks has that label now.

 

[Bidule0hm]

Oh, I see.

Then the only solution that I can think of is to identify the others drives, the only drive non-identified is the one that is unavailable.

And when I try to run your script (which I saved as DriveInfo.sh), I get:

Code:

+========+============================================+=================+

[Bidule0hm]

Hmm, I checked, there is no errors in the script. Can you post the output of cat -e DriveInfo.sh please?

Waow, some lines have a bunch of spaces (or maybe some other characters who mess-up the script) a the end, others don't have anything... WTF?

I created a pastebin to avoid any strange things that can happen with a copy-paste from the forum: http://pastebin.com/TXnFt2bf

Oh, I see.

Then the only solution that I can think of is to identify the others drives, the only drive non-identified is the one that is unavailable.

All the drives (except da12, which is a "non-hot" spare) show up with corresponding gpt labels.

But now I found that FreeNAS sent an email in the early hours of the morning reporting a SMART error on da5:

Code:

The following warning/error was logged by the smartd daemon:

Device: /dev/da5 [SAT], 1 Currently unreadable (pending) sectors

Device info:
ST32000641AS, S/N:********, WWN:5-000c50-03607df40, FW:CC13, 2.00 TB

For details see host's SYSLOG.

But smartctl shows da5 as PASSED.

Is the FreeNAS smartd daemon reporting bogus information?

And where do I find the SYSLOG I am advised to check?

Type more /var/log/messages in Shell.

OK. That works now. Thanks.

No problem ;)

I'm not sure I understand correctly: you're saying that the unavailable drive is not showing in the output of the ident script but all the connected drives are showing? (yeah I'm lost, pretty badly xD)

It's not because a drive pass the test that there is no problem. You can have some pending sectors and no problem. But the thing is the pending sectors generally doesn't stay low, when you have a couple of pending sectors you're pretty much guaranted that the drive will fail in the next weeks/days.

What I would do is to do a smartctl -a /dev/da5 to see the detailed status of the SMART on da5 ;)
