I decided to run a balance on my Pool today.
This seems to be running smooth, its 80% done, without any issues, it seems.
But DMESG shows some instances of this:
[390384.582746] BTRFS info (device sdb): found 292 extents
[390385.636504] BTRFS info (device sdb): relocating block group 28483803283456 flags 257
All of them for sdb. The drive doesn’t show any SMART errors or anything like that.
Is this something I should worry about?
