Need to identify disk in zpool ... how?

To get a disk serial requires that it is running and available:

• camcontrol identify <device> |grep ^serial (this might be (S)ATA specific)
• smartctl -i <device> |grep ^Serial
• reading the disk label once removed from the enclosure

In your case, I think the 3rd solution is the only available. So, Assuming you just want first identify the disk:

Try first a glabel status (as your drive is not shown as DOWN or REMOVED):

$ glabel status gptid/c7868819-ddc1-11e2-8c3e-00138f3fd9c7 N/A da0p1 gptid/c96da0bc-ddc1-11e2-8c3e-00138f3fd9c7 N/A da2p1 

1. You can see your partition with glabel status

Then you can easily identify the disk device name (ex: da0 for the gptid/c7868819-ddc1-11e2-8c3e-00138f3fd9c7 partition).

You can have a look at your system starting log from /var/log/messages (aka "dmesg"):

 $ dmesg | grep ^da0 da0 at mps0 bus 0 scbus0 target 0 lun 0 da0: <ATA ST3000DM001-1CH1 CC26> Fixed Direct Access SCSI-6 device da0: 600.000MB/s transfers da0: Command Queueing enabled da0: 2861588MB (5860533168 512 byte sectors: 255H 63S/T 364801C) 

2. You cannot see your partition with glabel status

    $ camcontrol devlist <ATA ST3000DM001-1CH1 CC26> at scbus0 target 0 lun 0 (pass0,da0) <ATA ST3000DM001-1CH1 CC26> at scbus0 target 4 lun 0 (pass2,da2) 

From there, you can easily spot which one is missing (da1 in this case), then have a look at dmesg to identify that disk.

So, no real solution here. I just hope that it help you see things a bit more clear.

• man glabel
• man camcontrol
• man smartctl

I made a script that lists all of the GPTID and associated hard drive serial number and device name.

#!/bin/bash #Use smartctl to get Serial Number - else dmesg is used USESMART=0 #save glabel status to temporary file CACHEGLABEL=1 if [ $CACHEGLABEL -eq 0 ] then GLCMD="glabel status" else GLTMP=/var/tmp/$0.glabel glabel status > $GLTMP GLCMD="cat $GLTMP" fi ADALOW=`ls /dev/ada[0-9] 2>/dev/null` ADAHIGH=`ls /dev/ada[0-9][0-9] 2>/dev/null` DALOW=`ls /dev/da[0-9] 2>/dev/null` DAHIGH=`ls /dev/da[0-9][0-9] 2>/dev/null` #check if all device nodes exist or skip if [[ $ADALOW == *ls* ]] then $DALOW= fi if [[ $ADAHIGH == *ls* ]] then $ADAHIGH= fi if [[ $DALOW == *ls* ]] then $DALOW= fi if [[ $DAHIGH == *ls* ]] then $DAHIGH= fi for FILE in $ADALOW $ADAHIGH $DALOW $DAHIGH do DEV=${FILE##'/dev/'} #echo -n "${DEV}: " if [ $USESMART -eq 0 ] then SERIAL=`grep $DEV: /var/log/dmesg.today |grep -i Serial | awk '{print $(NF)}'` else SERIAL=`smartctl -a $FILE | grep -i 'Serial Number'| awk '{print $(NF)}'` fi #this skips all ufs drives GPTID=`$GLCMD |grep 2$ |grep ${DEV}p|cut -d' ' -f1` if [ "${GPTID}x" == 'x' ] then GPTID="No GPTID" fi if [ "${SERIAL}x" == 'x' ] then $SERIAL="Not found" fi echo ${DEV}: Serial $SERIAL \; GPTID=$GPTID done if [ $CACHEGLABEL -eq 1 ] then rm $GLTMP fi 

You could try something like this. It worked for me:

devlist=$(sudo camcontrol devlist | awk ' { print $NF } ' | cut -f 2 -d , | sed 's/)//'g) for device in $devlist; do sudo camcontrol identify $device | grep serial; done 

that should output the entire list of serial numbers.

But it appears that I left a spare in there - ada0 - last time I was in the box. Can I replace ada2 with ada0 remotely? Until someone gets to the office?

Yes, zpool replace
