cluster/distribute: re-set layouts to prevent overlaps

2012-12-12T00:05:50+00:00

When subvols-per-directory option is used, with bricks addition/removal
the layouts might get distributed to other subvols, which were not part
of the layout before. We need to clean up layouts on old subvolumes, to
prevent overlaps.

Also, we need to make sure if layout-cnt is never less
than subvolume-cnt.

cluster/dht: dump the layout information of directories only

2012-11-19T10:58:06+00:00

testcase:
The changes are for removing gf_log from statedump related sections in dht and
using pthread_mutex_trylock in statedump sections. Changes are internal. So
tests were done by attaching gdb to the process and executing by manually
changing the values of some of the pointers.

cluster/distribute: Always return the latest time in struct iatt.

2012-10-16T21:27:15+00:00

save the a/c/mtime in inode_ctx, and dht_inode_ctx_update
checks the passed iatte, and updates the stat's time,
and inode_ctx's time accordingly. For preparent times, only
the iatt stat to be returned is updated, not the ctx.

With this, update, WIPE is removed, as we would always be passing
back the latest mtime, and hence cache times will be relevant.

TODO-handle rename WIPE calls

cluster/dht: handle percent option for 'min-free-disk'

2012-09-07T23:48:51+00:00

* with the init option cleanups, setting of 'conf->disk_unit'
  was reset, which made it not set the '%' in the option.

* bring a global check, which makes the option assume its
  percent, as long as value is < 100.

2012-08-14T06:24:04+00:00

Bring in option which is supported by posix xlator
to filter out directory's entries from being returned.
DHT would now request non-first subvols to filter out
directory entries.

dht xlator-option readdir-optimize will enable this
optimization
