Introduce new extended attribute: node-uuid

2012-02-23T07:19:44+00:00

Request for trusted.glusterfs.node-uuid returns pathinfo
like string but containing the UUID of glusterd instead
of the backend path for the requested file. This info
is benificial for tasks like parallel rebalance that will
make use of the UUID for data locality.

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.

getxattr returns a summary of no. of inodelks/entrylks cleared.
cmd_structure: trusted.glusterfs.clrlk.t.k[.{range|basename}]
where,
type = "inode"| "entry"| "posix"
kind = "granted"| "blocked" | "all"
range = off,a-b, where a, b = 'start', 'len' from offset 'off'

cluster/afr: Update fresh_children in lookup if no other ops in progress

2011-08-20T06:18:53+00:00

If write/truncate fails we should remove the child that failed the fop
from the fresh children. The previous code assumes that the children
that succeeded the fop are fresh children, which is wrong. Fixed that
in this patch.
