Currently on 4.11.8 No corruptions here either. 4.12.0 now, previously 4.12-rc5(ish, git), before that 4.11.0. I have however just upgraded to new ssds then wiped and setup the old ones as another backup set, so everything is on brand new filesystems on fast ssds, no possibility of old undetected corruption suddenly triggering problems. Also, all my btrfs are raid1 or dup for checksummed redundancy, and relatively small, the largest now 80 GiB per device, after the upgrade. And my use-case doesn't involve snapshots or subvolumes. So any bug that is most likely on older filesystems, say those without the no-holes feature, for instance, or that doesn't tend to hit raid1 or dup mode, or that is less likely on small filesystems on fast ssds, or that triggers most often with reflinks and thus on filesystems with snapshots, is unlikely to hit me. -- Duncan - List replies preferred.
