Hello One of the drives which I added to my array two days ago was most likely already damaged when I bought it - 312 read errors while scrubbing and lots of SMART errors. I want to take the drive out, go to my hardware vendor and have it replaced. So I issued the command: "btrfs dev del /dev/sdf /mnt/btrfs-raid". It has been going on for about an hour now. It seems that removing the drive triggered a balance operation - "btrfs fi show" shows /dev/sdf as having Zero Data on it, while the size of the data stored on the other drives is increasing. What I would like to know is where btrfs takes the data to be replicated from - from the others drive or from the device about to be removed? I am using RAID1 on data, metadata and system so there should be a good copy of all the files on /dev/sdf. I just want to be certain that the damaged data on /dev/sdf are not spread around the filesystem in which case restoring my backup would be the best idea.
