Heh, that is annoying though. > 2. the current git btrfs-show and btrfs fi show both output > *different* devices for device with UUID > b5dc52bd-21bf-4173-8049-d54d88c82240, and they're both wrong. does blkid output find that uuid anywhere? Since you're working in git, can you maybe do a little bisecting to find out when it changed? Should be a fairly quick test? -Eric > Somewhat confusingly, /dev/disk/by-uuid/ only shows three devices: > > bd40cb4e-93bb-4600-8455-ca1185aa8abe -> ../../md3 > 7feedf1e-9711-4900-af9c-92738ea8aace -> ../../sda3 > 4f0b27a5-5f5b-413c-a71b-b5a3bec5482c -> ../../md2 > > What's going on with the varied output from (git) btrfs-show vs. > 'btrfs fi show' (vs. the older, as-shipped btrfs)? > > -- 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
