Hello all,
I have a btrfs raid-0 array (initially a raid-6 but long ago converted due to warnings not to use raid56, not that I think this impacts my situation). One of the disks in the array started to go bad. Some bad sectors meant one of my video files was unable to be read. This issue was discovered during a btrfs scrub. By deleting the offending file occupying the bad sector, I was able to successfully remove the offending disk from the array. Replacement disk is in and no issues, restored the file from backup. Great. My problem now is the following warning message repeatedly spamming my system logs every minute (even after fresh reboot and everything with the disk management settled). "kernel: device-mapper: core: btrfs: sending ioctl 5331 to DM device without required privilege." I have never seen the error before the disk issue, and I have confirmed it only started after a reboot after the disk had started going bad. I've not been able to figure out any other factors that maybe contributing. Everything appears functional and without issue, and I see no consequences of these messages in system performance or behaviour. I'm running fully updated Fedora 25 which is using btrfs-progs version 4.6.1-1.fc25 on kernel 4.11.3-200.fc25.x86_64. Has anyone ever seen this issue? Any help or advice would be greatly appreciated, thank you.
