How to attach back accidentally unpluged drive

[Igor Voskresenskiy]

Accidentally I unplugged external USB drive. How can I mount it back to my FreeNAS system?

In "View volumes" I can see my detached volume.

I tried to import volume, but I can't see my vol.

Why I can't import my drive back?

Physically the drive is present in my devices.

Did you try rebooting?

Did you try rebooting?

Yes, and it didn't help

This is one reason that use of USB drives is discouraged.

So bak3, is that A pool? What's the output of zpool import? I suspect it's empty. Does the drive leave log messages when you connect the USB?

I found the solution. I just ran
zpool clear <poolname>
and after that it attaches back and becomes online. I tried some experiments with detaching USB drive and it works almost all the time. If it does't work, just try to import it againt after clearing
