Variable IOBUF: Use variable iobuf for cli/glusterd/glusterfsd(mgmt)

2011-08-01T06:15:32+00:00

By using variable iobufs, xfer data size is no more limited to
128K (default). This helps in scaling.

glusterd rebalance: use lstat() instead of stat()

2011-07-19T15:51:26+00:00

so the symlinks pointing to directories are not considered
as directories themself and the control flows outside
gluster's scope

distribute: bring in feature to do rebalance from inside

2011-07-14T08:01:44+00:00

do the 'rebalance' on a file with 'setxattr()' with
'distribute.migrate-data' key. the valid 'value' is "force" or
anything else.

current implementation of 'rebalance' is same as 'glusterd-rebalance',
and hence comes with limitation of not rebalancing hardlinks, non-regular
files, and files with open-fds.

distribute: handle 'fix.layout' key in setxattr() instead of getxattr()

2011-06-24T04:31:16+00:00

as 'fix.layout' command does changes to directory layout, its not a
'read/get' type of operation, and hence as per the symantics, it suits
setxattr() better

also fix a memory leak in getxattr(), where 'local' was allocated twice
in few cases

gluster rebalance: bring in a 'force' option

2011-06-17T05:01:59+00:00

* also correct the free space available logic to check the size
  without the file in migration (this considers the sparse files too)

* 'force' option will bypass the free-space check logic, hence will
  cleanup all the linkfile

* 'force' option is valid only with 'migrate-data' option
