The FUSEx client is a more posix confirm and performant re-implementation of the FUSE client. It allows to access EOS as a mounted file system.
There a two FUSEx client modes available:
daemon user description eosxd !root An end-user private mount which is not shared between users eosxd root A system-wide mount shared between users
The MGM requires an additional open port (default 1100) to distribute callbacks to clients using ZMQ as distribution network.
eosxd client rates can be limited using the rate limiter interface available via the access command in the CLI.
# limit the access for listing to 100 Hz per user
eos access set limit 100 rate:user:\*:Eosxd::prot::LS
# limit the access for stats to 1000 Hz per user
eos access set limit 1000 rate:user:\*:Eosxd::prot::STAT
# limit the access for returning list entries to 10 kHz per user
eos access set limit 10000 rate:user:\*:Eosxd::ext::LS-Entry
# limit the access for meta-data updates to 1 kHz per user
eos access set limit 1000 rate:user:\*:Eosxd::prot::SET
LS, STAT and SET limits are applied by the corresponding server side protocol methods. LS-Entry is applied when another LS call is requested. Please note the difference in the naming of the prot and ext counter types.
