Hi all,
## Whats my setup?
A laptop runs FreeBSD with ZFS on virtualbox. I have a mirror ZFS pool of which 1 drive is the drive of my laptop and one drive is a USB external drive that I regularly connect to sync . It's a backup in case something goes wrong. Until now this mirrored USB drive came in handy 1 time, where my VM broke completely. Mostly the VM breaks because of issues with the Virtual box and host OS where the Virtual box is running.
## What goes wrong now?
There were too many errors so the disk could not be resilvered. I decided to remove the complete da0 device, recreated all the partitions with the goal to replace the faulted disk. However this fails again.
## What is the problem?
1. I am trying to find out what is exactely wrong
2. Did some attempts to use smartctl but it is not build for usb drives.
3. Any help is appreciated.
Thanks in advance,
Best Regards,
R
