cluster/dht: clear local->cached_subvol when switching to do_fresh_lookup

2011-08-06T12:49:22+00:00

The presence of local->cached_subvol makes dht_lookup_everywhere_done behave
as though it was a lookup on a file where linkfile needs to be recreated. In
a fresh lookup, local->cached_subvol should be NULL.

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

core: fill 'ia_ino' from 'ia_gfid' in 'storage/posix' to preserve same ino number

2011-06-17T06:24:56+00:00

take the least significant 64bit from gfid and assign it to 'ia_ino',
hence for a given file (or directory), the 'ia_ino' number is always
same, and we need not worry about the 'itransform' in 'cluster/*'
translators.
