errors: No known data errors
When I try to remove the log device, I get the following error message.

Code: 
[root@bsd ~]# zpool remove tank log label/label/disk15
cannot remove log: no such device in pool

I can't run any zpool or zfs command after running the zpool remove command.
I even can't kill the process, I think because the diskwait 'D+' state

Your pool name is logs but you are trying to remove log

Your dmesg also suggests gpt corruption. Can you post the output of:

[CMD=""]#gpart show[/CMD]
 
I'm not quite sure how you have managed to get a device called 'label/label/disk15'?
They are usually 'label/labelname' as with all your array disks.

Anyway the error you are getting is because you have the remove command wrong. (At least based on the same command in FreeBSD 8.2/ZFS v15)
It should just be:

[CMD="zpool"]remove poolname device[/CMD]
ie: [CMD="zpool"]remove tank label/label/disk15[/CMD]

You are trying to remove a disk called 'log', which obviously doesn't exist in the pool - as made clear by the error message. The fact that it locks up might be an issue with the dev version of ZFS.

I don't think the GPT errors are related to your ZFS problem but it's not right.
Is there are reason for using partitions rather than just labelling the entire disks?
 
Thank you for the feedback. I was experimenting with zfsguru and nexenta in the past, I must have been done something wrong:)

I've destroyed old GPT tables and relabeled the disks.
[CMD=]# gpart destroy -F da1[/cmd]
[CMD=]# glabel label disk1 /dev/da1[/CMD]

Removing the log device works fine now with your commands. Thanks.
