A caching FUSE filesystem for all types of slow mounts, like glusterfs, which still has no caching. Apart from caching, fancy logic like rule-based filters and hooks can be implemented pretty easily. Consider this a middleware filesystem.
Originally used with glusterfs (miss + gluster = misster).
Should be thread-safe.
WARNING: this is a development version, please backup your files. We do not guarantee data integrity, safety, or anything else for that matter. Seriously.
CAUTION: on 64-bit systems with Python compiled without LFS support this utility will break, since inodes will overflow. Launch gluster without LFS support in such cases using the enable-ino32 flag.
python misster.py <mountpoint> -r <source> -c <cachedir>
Cache directory size limit -m BYTES, default is 1G.
Add more background threading capacity by supplying the-t option (highly experimental, will probably mess up ordering of operations on the same file due to race conditions).
Add -o allow_other,default_permissions if intending to use across users (recommended).
python -m unittest -v tests
The source layer cannot be used concurrently by several entities. The caching layer will become unsynchronised if changes are done outside of misster's target mount.
