If I had a way to know which filename o1845158-142-0 refers to, it would help :) Ahh, I see that I do, grepped for inode 1818495 in tree -adf --inodes | less You don't want me to send the output, it's megabytes worth, but here's what changed: Before: /mnt/btrfs_pool1/home_ro.20140209_12:00:01/merlin: ├── [1845158] ./gg-src/chromiumos/chroot/usr/share/zoneinfo/posix/America │ ├── [1845159] ./gg-src/chromiumos/chroot/usr/share/zoneinfo/posix/America/Argentina │ ├── [1845172] ./gg-src/chromiumos/chroot/usr/share/zoneinfo/posix/America/Indiana │ ├── [1845181] ./gg-src/chromiumos/chroot/usr/share/zoneinfo/posix/America/Kentucky │ └── [1845184] ./gg-src/chromiumos/chroot/usr/share/zoneinfo/posix/America/North_Dakota In my new subvolume, I have this instead (directory is indeed gone, there are other 2 with the same name/hierachy, maybe even the same contents): After: /mnt/btrfs_pool1/home/merlin: legolas:~/gg-src$ tree -adf --inodes | grep zoneinfo/posix/America │ ├── [4172524] ./ProdNG/PNG_test/chroots/borg/usr/share/zoneinfo/posix/America │ │ ├── [4172733] ./ProdNG/PNG_test/chroots/borg/usr/share/zoneinfo/posix/America/Argentina │ │ ├── [4172734] ./ProdNG/PNG_test/chroots/borg/usr/share/zoneinfo/posix/America/Indiana │ │ ├── [4172735] ./ProdNG/PNG_test/chroots/borg/usr/share/zoneinfo/posix/America/Kentucky │ │ └── [4172736] ./ProdNG/PNG_test/chroots/borg/usr/share/zoneinfo/posix/America/North_Dakota ├── [4188826] ./ProdNG/PNG_test/usr/share/zoneinfo/posix/America │ ├── [4189034] ./ProdNG/PNG_test/usr/share/zoneinfo/posix/America/Argentina │ ├── [4189035] ./ProdNG/PNG_test/usr/share/zoneinfo/posix/America/Indiana │ ├── [4189036] ./ProdNG/PNG_test/usr/share/zoneinfo/posix/America/Kentucky │ └── [4189037] ./ProdNG/PNG_test/usr/share/zoneinfo/posix/America/North_Dakota > against the root of the subvolume and lets us know what the full > output is.

I still have the snapshot send/received failed at and the current volume, so it's not too hard for me to give you other diffs like that, but the full output would be very very large and not appropriate for posting here :) Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
