move on enospc when writing feature. closes #141
move on enospc when writing feature. closes #141
This feature mimics the standard mhddfs behavior but is more thorough. If a write fails and the errno is set to ENOSPC then mergerfs will (if the feature is enabled) attempt to move the file to the drive with the most free space but only if it has enough room for the file plus the amount to be written. If that transfer is successful it will then unlink the original file and attempt the previously failed write again. The copy includes copying the path and file including the acls, owners, attributes, extended attributes, and timestamps.pull/144/head
