I'm hoping someone can help educate me on what happened to my server last night. I was using Krusader to move a couple TB of data from one disk to another, to consolidate a share. It was going to take 8 hours or something significant like that, so I let it transfer overnight.

Then this morning, I see that one of the disks involved in the transfer is reporting read errors(s) and now I'm rebuilding the data on that disk. All of my disks are fairly new Ironwolf Pro, and I highly doubt there's anything wrong with this disk. In fact, I think this has happened to me before.
Looking at my system logs, I found the lines below from 3am, regarding disk sdo, which is the disk with errors. Am I correct in assuming that this was caused by CA Backup/Restore trying to stop Krusader while I had a file transfer in progress? If so, is there any way I can prevent this in the future?

Thanks,

Steve

Logs are spammed with errors related to an unassigned NTFS device, because of that there are several hours missing.
