| I have three devices which I use for testing a btrfs-based backup solution on a fedora rawhide machine with the 3.14.0-0.rc3.git2.1.fc21.x86_64 kernel. I have created a d=raid1, m=raid1 array by first filling a disk and then running balance -dconvert=raid1 -mconvert=raid1. The second part of my routine is failing a drive and replacing it with the third, spare drive. For the first test, I wanted to go the simplest of all routes: the drive fails, while the btrfs partition is not mounted and I notice this before I even try to mount it again. This should be a wash | |
| 1. mount -t btrfs -o degraded /dev/sdg /data #mount btrfs | |
| 2. btrfs device add /dev/sdh /data #add new device to btrfs | |
| 3. btrfs device delete missing #delete missing device | |
| Now the second step already fails, because btrfs device add never finishes, allthough iotop shows no activity at all. What you see in [03] and [04] is the dmesg output. |
