Test for a btrfs incremental send issue where we end up sending a
wrong section of data from a file extent if the corresponding file
extent is compressed and the respective file extent item has a non
zero data offset.
Fixed by the following linux kernel btrfs patch:
Btrfs: use right clone root
For non compressed extents, iterate_extent_inodes() gives us offsets
that take into account the data offset from the file extent items, while
for compressed extents it doesn't. Therefore we have to adjust them before
placing them in a send clone instruction. Not doing this adjustment leads to
the r

A user was running into errors from an NFS export of a subvolume that had a

Sometimes it is useful to see what btrfs restore is going to do
before provisioning enough external storage to restore onto.
Add a dry-run option so we can see what files and paths are found
by restore, without actually restoring any data.

By the way, I was happy to recover
Currently, btrfs balance start fails when trying to convert metadata or

requires that a conversion from a multi-device filesystem to a single
