[solved] How to debug problems with the one of the drives in VM?

[georgy.goshin]

Hi again

After I tried to get the info about the desired dataset I tried to boot the VM once again and it is working and mount point available.

How to remove the thread please? Seems it was written by mistake.

Thanks.




Hello

I've shutdown one linux VM and can't start it back because one drive is not accessible.

Linux writes /dev/sdb: Can't open block dev

is it busy? is it corrupted? please advice how to catch the problem?

In the machine properties it's listed as
Hard Disk (scsi1) ds1:vm-105-disk1,iothread=1,size=10T


zfs list shows

It's not possible to remove a thread. Thank you for reporting the solution. You can mark it Solved by editing the first post.

EDIT: There is a pull-down menu when you edit the thread where you can select Solved instead of typing it yourself.
