on GitHub

Dear MooseFS Users,

MooseFS 3.0.112 is now stable!

This release is a bugfix and feature release. It introduces support for disabling individual filesystem commands in Master Server (configurable in mfsexports.cfg) and respecting them on the Client side (issue #344). It also adds support for STRICT and LOOSE mode in KEEP and ARCHIVE (issue #249). This release fixes various other issues too, including a workaround for Linux kernel bug related to EBUSY issue by adding directory entry invalidator (issue #98).

We would like to thank all the contributors who helped us making this release, especially (alphabetically):
@borkd, @Damien9527, @linux-ops, @MonkeyFang, @onlyjob, @pault28, @tnktls.
Thank you for all your valuable input, help and making MooseFS better!
