[Moosefs-users] Latest stable release of MooseFS 1.6.25

[Michał B. <mic...@co...>]

Hi!

 

As promised we prepared the next release of MooseFS - 1.6.25. Most important
changes include:

* (master) improved chunk deletion algorithm (soft/hard limits per
chunkserver)

 

Now chunk deletion speed is configured by soft and hard limits. What is
important the limits since this version are set per chunkserver (not
globally). Deleting large amount of files should not slow down the whole
system:

- CHUNKS_SOFT_DEL_LIMIT = 10

- CHUNKS_HARD_DEL_LIMIT = 25

 

* We also modified default config values for replication:

CHUNKS_WRITE_REP_LIMIT = 2

CHUNKS_READ_REP_LIMIT = 10

 

which should better fit most of the installations. You should fine tune
these values according to the amount of chunkservers and average size of the
chunks. Mind that too agressive replication will slow down the whole system.

 

* (master+mount) added 'sugidclearmode' and 'mkdircopysgid' compatibility
options (inspired by Sébastien Morand)

 

* fixed Debian init scripts  (thanks to Steve Wilson)

 

 

 The recommended upgrade order is as usual: mfsmaster, then metaloggers,
then chunkservers and at last client machines.
