Dear community, I'd like to kindly ask you for a little help in my situation:
I'm running a ZFS pool of 3 drives. What happened is - a power cable powering 2 drives had a bad contact, so I started loosing 2 out of 3 drives and having a lot of UDMA errors and CAM status timeouts etc.
Yesterday I fixed the power cable, zpool is ONLINE with no errors, but some permanent errors can be seen:
All three log files are returning an input/output error:
What is the correct way to fix this, so I don't mess up the system and all my data stored on the pool?
Many thanks
Mike
