Hi list, I'm regular on this list and I very like btrfs, I want use it on production server, and I want replace hw raid on it.
Test case: server with N scsi discs 2 SAS disks used for raid 1 root fs If I just remove one disk physically, all okay, kernel show me write errors and system continue work some time. But after first sync call, example # sync # dd if=/Dev/zero of=/zero Kernel will crush and system freeze. Yes, after reboot, I can mount with degraded and recovery options, and I can add failed disk again, and btrfs will rebuild array. But kernel crush and reboot expected in this case, or I can skip it? How? # mount -o remount, degraded -> kernel crush Insert failed disk again -> kernel crush May be I missing something? I just want avoid shutdown time or/and reboot =.=
