Hello, On two machines I have subvolumes where I backup other hosts' root filesystems via rsync. These subvolumes have the +c attribute on them. During the backup, sometimes I get tons of messages like these in dmesg: [Wed Jul 25 20:58:22 2018] BTRFS error (device dm-8): error inheriting props for ino 1213720 (root 1301): -28 [Wed Jul 25 20:58:22 2018] BTRFS error (device dm-8): error inheriting props for ino 1213723 (root 1301): -28 [Wed Jul 25 20:58:22 2018] BTRFS error (device dm-8): error inheriting props for ino 1213724 (root 1301): -28 [Wed Jul 25 20:58:22 2018] BTRFS error (device dm-8): error inheriting props for ino 1213725 (root 1301): -28 # btrfs inspect inode-resolve 1213720 . ./gemini/lib/modules/4.14.58-rm2+/kernel/virt This seems to be related to the "compression" property in Btrfs: # btrfs property get ./gemini/lib/modules/4.14.58-rm2+/ compression=zlib # btrfs property get ./gemini/lib/modules/4.14.58-rm2+/kernel/virt (no output) Why would it fail like that? This does seem harmless, but the messages are annoying and it's puzzling why this happens in the first place. -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
