  • v3.13.0-rc3 Changes

    August 24, 2020

    Dear Users,

    πŸš€ 3.13-rc3 (release candidate) is officially out!

    What's new

    πŸš€ Updated packaging for current releases of popular distributions:

    • Debian 10.4
    • Ubuntu 20.04
    • CentOS 8

    Known issues by severity

    grave

    • ⬆️ upgrading from 3.12 to 3.13 can potentially lose EC chunks

    major

    • πŸ‘€ seekdir/telldir does not work properly, especially seekdir with negative offsets
    • chunk replicated onto a drive that fails during a write operation can end up in limbo state (undergoal) until chunkserver is restarted

    minor

    • πŸ“¦ uRaft package is not integrated yet (not ready for use)
    • βœ… Ganesha has not been tested yet
    • chunk rebalancing behavior is flaky (is some scenarios it takes more time than it should)

    Future plans

    LizardFS team plans for two more rc versions before an actual 3.13 release:

    • rc4 - fix all known grave and major issues
    • rc5 - integration of uRaft and Ganesha
  • v3.13.0-rc2 Changes

  • v3.13.0-rc1 Changes

    July 17, 2018

    Dear Users,

    πŸš€ 3.13.0-rc1 (release candidate) is officially out!

    Featuring:

    • uRaft HA
    • πŸ›  fixes to EC handling
    • πŸ”Œ nfs-ganesha plugin changed to use only C code
    • ⬇️ reduced number of secondary groups retrievals
    • βž• add fuse3 client
    • πŸ›  many fixes

    Detailed info:

    • uRaft HA *

    uRaft is HA solution designed for use with LizardFS. It allows for seamless switching
    of master server in case of hardware failure. More information about uRaft is available
    πŸ“„ in LizardfFS Handbook (https://docs.lizardfs.com/index.html)

    • πŸ›  fixes to EC handling *

    For chunk types with number of parity greater than 4 there could occur situation when
    it wasn't possible to recover missing data. This was low probability event but nonetheless
    it could happen. To solve this problem we have to recompute parity parts for those types of chunks.
    Unfortunately until all parity parts are recomputed affected chunks are in endangered state.

    • πŸ”Œ nfs-ganesha plugin changed to use only C code *

    πŸ”Œ In preparation for moving LizardFS nfs-ganesha plugin to official nfs-ganesha repository,
    🚚 we had to remove all occurrences of C++ code and replace it with plain C.

    • ⬇️ reduced number of secondary groups retrievals *

    In LizardFS we introduced handling of secondary groups. Unfortunately the function to retrieve
    secondary groups in FUSE library turned out to be using a lot of CPU resources. Thanks to removing
    🐎 unnecessary calls to this function, mount performance increased significantly.

    • βž• add fuse3 client *

    LizardFS now include mount3 client which uses FUSE3 library. Thanks to new features in FUSE3,
    πŸ‘ now mount performs much better in many scenarios. Here are the most important changes visible
    to LizardFS users:

    • 0️⃣ big_writes option is now enabled by default (also it isn't recognized as a parameter anymore).
    • βž• Added writeback_cache option. With kernel 3.14 and newer this
      🐎 enables write-back caching which can significantly improve performance.
    • 🐎 increased read/write performance (specially for small operations)

    🐧 Because most of the Linux distributions don't include FUSE3 library, we have build FUSE3 packages
    and made them available on LizardFS page (https://lizardfs.com/)

  • v3.12.0 Changes

    December 21, 2017

    Dear Users,

    3.12.0 is officially out!

    Featuring:

    C API
    πŸ”Œ nfs-ganesha plugin
    RichACL - a new POSIX + NFSv4 compatible ACL standard
    πŸ‘ OSX ACL support through osxfuse
    ACL in-memory deduplication
    0️⃣ client readahead enabled by default
    πŸ”’ file lock fixes
    πŸ‘ AVX2 support for erasure code goals
    πŸ›  MinGW compilation fixes
    more flexible chunkserver options
    πŸ›  many fixes
    Detailed info:

    C API *
    LizardFS 3.12 comes with liblizardfs-client library and C language API header.
    πŸ— It's now possible to build programs/plugins with direct support for LizardFS operations,
    πŸ‘€ no FUSE needed. For reference, see:
    src/mount/client/lizardfs_c_api.h
    src/data/liblizardfs-client-example.c

    For those building LizardFS from source, pass a -DENABLE_CLIENT_LIB=YES flag to cmake
    πŸ— in order to make sure you're building client library as well.

    πŸ”Œ nfs-ganesha plugin *
    πŸ”Œ Our official plugin for Ganesha NFS server is included as well. This plugin enables
    a LizardFS FSAL (File System Abstraction Layer) to Ganesha, which is then used
    πŸ”Œ to access LizardFS clusters directly. Our new plugin is pNFS and NFSv4.1 friendly.

    For those building LizardFS from source, pass a -DENABLE_NFS_GANESHA=YES flag to cmake in order to make sure you're building client library as well.

    RichACL *
    πŸ‘ In order to extend POSIX access control list implementation we introduced RichACL support.
    Backward compatibility with POSIX ACLs is guaranteed. Additionally, it's possible to use NFSv4-style ACL tools (nfs4_getfacl/nfs4_setfacl) and RichACL tools (getrichacl/setrichacl) to manage more complicated access control rules.

    OSX ACL *
    πŸ’» Setting/getting ACLs is also possible on OSX via both command line chmod/ls -e interface and desktop.

    πŸ”’ File lock fixes *
    πŸ”’ Global file locking mechanism is now fully fixed and passes all NFS lock tests from connectathon suite.

    AVX2 *
    Erasure code goal computing routines now take full advantage of AVX2 processor extensions.

    MinGW *
    πŸ†“ LizardFS is now bug-free again for MinGW cross-compiling.

    Chunkserver options *
    πŸ”§ Replication limits are now fully configurable in chunkserver config.
    βœ… Also, chunk test (a.k.a. scrubbing) has 1 millisecond precision now instead of previous 1 second, which allows users to turn on more aggressive scrubbing with simple chunkserver reload.

    Best regards,
    LizardFS Team
