I have a ZFS pool set up with 2nr new 4TB SSD's in mirrored config. They were both running fine for approx a month until I noticed health warnings on the pool. One of the SSd's had dropped out and was not detected in the disks listed within the system. When I remove both disks and reinstall them proxmox disk utility picks both back up again. I wiped both disks and reset up the mirrored pool again and all ran well for approx a week when i noticed the same thing again. It is the same disk that is dropping out. Again if i power off the system and restart the disk comes back online again, but after a while it drops out again. When i restart proxmox and check the smart data both within proxmox and on another pc they both say the disk is ok and in the same health as the other disk. I dont know why the pool keeps dropping the same disk. im not sure how to tell if the disk is faulty or if this is a proxmox software issue that keeps dropping the disk out of the pool. I have another ZFS pool with 2 HHD's mirrored and there is no issues there. just looking to see if there is anything i can try to confirm what is happening or confirming if disk is faulty
