mempool: add more counters to understand the usage scenarios properly

2012-02-27T10:18:35+00:00

current design of mempool is to fallback to standard calloc/free if
all the buffers in pool are exhausted. Understanding more about those
numbers will help us to tune mempool parameters properly over time.

cli: print the type of the inode in gluster volume status inode output

2012-02-22T17:42:25+00:00

Instead of a number print the type of the inode in the output of
gluster volume status inode. This is what the output symbols indicate.

R -----> Regular file
D -----> Directory
L -----> symbolic Link
B -----> Block special device
C -----> Character special device
F -----> FIFO
S -----> Socket
I -----> Invalid inode type

Also supress a warning message displayed at the time of build.

mempool: adjustments in pool sizes

2012-02-22T12:23:48+00:00

* while creating 'rpc_clnt', the caller knows what would be the ideal
  load on it, so an extra argument to set some pool sizes

* while creating 'rpcsvc', the caller knows what would be the ideal
  load of it, so an extra argument to set request pool size

* cli memory footprint is reduced

cli, glusterfsd: Fixes for "volume top {read,write}-perf"

2012-02-21T10:48:57+00:00

Changed variables to use unsigned types, to support larger comninations of
block_size * block_count
Also increases cli time out for "volume top" ops to 600, to allow more time
for glusterd to return the results to cli.

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.

libglusterfs: Implement circular buffer and event history

2012-02-20T14:59:11+00:00

Implement circular buffer framework, so that it can be used by other components
such as event history management. And event history is implemented which can
be used by xlator to dump some information to a file (such as information of some
structure etc).

Through statedump, history of each xlator can be dumped. An option called history
should be given to the statedump command.

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
