Re: btrfs raid1 filesystem on sdcard corrupted

Thank you all for your responses! The second device that failed yesterday booted normally today when I wanted to investigate it. Not sure if it really had the same problem. Is it likely that such r/w problems come and go again? Both of these devices were equipped with with Kingston SDC4/8GB

Thanks Lionel for your explanations! I just noticed that a second device with the same setup (which has been working only some hours ago) failed as well. So two systems which were running with a non-raid1 and non-btrfs setup for weeks or months before, and which were updated to the
