core: utilize mempool for frame->local allocations

2012-02-21T10:42:09+00:00

in each translator, which uses 'frame->local', we are using
GF_CALLOC/GF_FREE, which would be costly considering the
number of allocation happening in a lifetime of 'fop'. It
would be good to utilize the mem pool framework for xlator's
local structures, so there is no allocation overhead.

cluster/distribute: send the right 'dict' for check_is_linkfile()

2012-02-21T10:41:42+00:00

earlier we were using 'check_is_linkfile_wo_dict()' for readdirp_cbk(),
which is no more required now.

cluster/dht: Support for hardlink rebalance when decommissioning

2012-02-19T12:47:50+00:00

The support for hardlink rebalance is only available for decommissioning
of a node. this can be triggered in two ways
1. remove-brick start
2. if decommission node value is set in vol file, then a normal rebalance
   command

The way we handle it is-
if (nlink > 1)
do
       * if src file doesnt have linkto xattr
                * mark src's linkto to the dst
       * else
                * perform a link on the dst
                * do a look up
                * if nlinks = dst.nlinks
                        * migrate data
                * else
                        * continue crawling
done

cluster/dht: Rebalance will be a new glusterfs process

2012-02-19T09:31:19+00:00

rebalance will not use any maintainance clients. It is replaced by syncops,
with the volfile. Brickop (communication between glusterd<->glusterfs process)
is used for status and stop commands.

Dept-first traversal of dir is maintained, but data is migrated as and when
encounterd.
fix-layout (dir)
do
        Complete migrate-data of dir
        fix-layout (subdir)
done

Rebalance state is saved in the vol file, for restart-ability.
A disconnect event and pidfile state determine the defrag-status
