MooseFS 3.0.104 is now stable! This release includes both bugfixes and new features.

We would like to thank all the contributors who helped us making this release, especially (alphabetically): @borkd, @dragon2611, @nickb937, @njaard, @onlyjob. Thank you for all your help!

(If I forgot to mention somebody, I am very sorry and please let me know!)

Please find the list of fixes this release includes below:

• (master) fixed taking into account labels in classes 1-9
• (master) fixed recovering userperm and otherperm in ACL (in practice it doesn't matter – mainly cosmetics)
• (cli+cgi) fixed python3 compatibility issue (casting to int for %X format)
• (master) increased mmap allocation block size (Linux kernel issue – too many mmaps leads to memory not being properly released by the kernel)
• (client) fixed handling internal packets with size zero (client disconnection during chunkserver registration)
• (client) fixed symlink cache handling (potential race condition)
• (master) added global option for preventing using same ip or same rack for more than one chunk copy
• (client) added ignoring _netdev option – sometimes needed in case of mounting from fstab
• (master) added defining rackid as string paths in mfstopology.cfg (introduced optional higher distances between servers)
• (master) fixed desync on adding damaged chunk
• (master) added changelog save mode (background, async and sync)
• (all) fixed issues reported by cppcheck (fixes #179)
• (cli+cgi) fixed issues reported by pylint (fixes #180)

• (metatools) fixed conflict with builtin function humanize_number (NetBSD)
• (master) better handling chunks with pending high-priority jobs
• (master) long loop detection (log info whenever time between polls is longer than 5 seconds)
• (master) fixed condition that checks if thare are all chunkservers and all chunks available (and using it for detecting ENOSPC condition – issue #201)
• (mount) added .params pseudofile with mfsmount working parameters (such as cache sizes, timeouts etc.)
• (cs) fixed removing chunks from data structures when marking disk as 'damaged' (issue #207)
• (cs) fixed handling 'damaged' disks with chunks on reload (issue #207)
• (cs) unlink duplicates week after detection (instead of removing them instantly – related to issue #207)
