-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have two 2TB disks formatted as a btrfs raid1 array, mirroring both data and metadata. Last night I started
# btrfs filesystem balance <path> and it is still running 18 hours later. This suggests that most stuff only gets written to one physical device, which in turn suggests that there is a risk of lost data if one physical device fails. Or is there something clever about btrfs raid that I've missed? I've used linux software raid (mdraid) before, and it appeared to write to both devices simultaneously. Is it safe to interrupt [^Z] the btrfs balancing process? As a rough guide, how often should one perform a) balance b) defragment c) scrub on a btrfs raid setup?
