I've been having lots of problems with my docker apps. Configs mysteriously become read-only, docker apps not starting up at all, database issues, possible corrupt docker image.
After some digging, i see the following warning in syslogs repeating several times every 30sec.
Tower kernel: program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO
Since smartctl is used to read disks' SMART info, I suspected my drives, and found the attached disk log on one of my two cache SSDs. The two SSDs are identical brand new drives I recently bought. Previously was not using cache pools.
Also using smartctl to read that drive returned:
Short INQUIRY response, skip product id
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
Is this indication of a bad SSD?
Also, possibly related info, whenever I've rebooted the server, I'd lose one of the cache SSDs. I have to manually unplug and replug the power to that drive for it to be detected. I don't reboot often, so didn't think much of it.
Diag also attached.
