I just tried btrfs rescue chunk-recover (btrfs-progs 4.6) on new Btrfs, 3x raid5 with 1 dev missing. I get:
[root@f24s ~]# btrfs rescue chunk-recover /dev/VG/2 Scanning: DONE in dev0, DONE in dev1 open with broken chunk error Chunk tree recovery failed So I don't think rescue chunk-recover can work degraded. At least, it's not working now, and if it isn't meant to work it probably should fail before it does the scanning, which takes a long time. I filed a bug: https://bugzilla.kernel.org/show_bug.cgi?id=121471 But in my case things still continue to work with btrfs-find-tree and degraded mount works OK, so off hand I don't think the rescue chunk-recover made things worse. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
