Hi, I'm running Kernel 4.3 and Btrfs-tools 4.3 on Debian Jessie. I compiled the tools and kernel myself.
Recently I added a new disk to my btrfs volume and wanted to proceed to convert from single to raid1. Unfortunately the new disk seems to be faulty and started throwing a lot of errors. The balance convert operation didn't manage to finish, and now I'm trying to get my btrfs volume back to single mode so that I can mount it read/write. If I try to mount it degraded, then it complains that there are too few devices to mount writeable. So it will only allow me to mount read-only. So far, so bad. I have managed to boot and mount the volume once, with the faulty disk and cancel the balance operation. Now I would like to convert it all to single again, so that I can finally remove that faulty drive. However, if I simply say btrfs fi balance start -dconvert=single -mconvert=single /btrfs-volume Wouldn't that theoretically move some blocks to the faulty drive? Can I somehow specify to rebalance only the working drive? I was thinking by specifying the device id, which seems possible according to the manpage. I just wanted to check with you guys first, if that should work as expected, or will I run into further trouble? Also, I understand -dconvert is for data, and -mconvert is for metadata, but is -sconvert? Is that data and metadata combined, or are system chunks something else entirely?
