Release Date: 2020-03-24 // about 4 years ago

  • 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):
