Ok, so looking up subvols by name uses the default subvol to resolve the name, and so when I change the default subvol to the snapshot of @, there is no @home name there pointing to the subvol? Things make much more sense knowing that. I thought that the subvolumes had their own namespace outside of any one subvolume. Is there a way to create another name entry in @snap that points to @home, or can you only have the original @home entry in the default subvol? > To backup > ~# mount /dev/sda1 /mnt > ~# ls /mnt > @ @home > ~@ btrfs sub snap /mnt/@ /mnt/@rootsnap > ~# ls /mnt > @ @home @rootsnap > > And to rollback: > ~# mv /mnt/@ /mnt/@rootmessy > ~# mv /mnt/@rootsnap /mnt/@ > And just reboot, since it just mounts whatever is named "@/". Perfect... I think I'll keep the default subvol mounted under /.subvols to make managing them easy. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk6nYtIACgkQJ4UciIs+XuJ/CQCgsbMLAY/h9opq/T7qBJKKrSz2 v0cAnRq8PKp1jx9r4Q6X4J6Ixjv3KpeS =GSCn -----END PGP SIGNATURE----- -- 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
