rpc-clnt: use the correct xdr_size for getting the iobuf

2012-04-19T07:28:39+00:00

earlier we used to get the size of rpc_msg from an empty msg, which
was resulting in minimum size allocated for rpc-msg. the correct way
is to fill the required fields in rpc_msg structure and then calculate
the size, and allocate the iobuf.

cluster/afr: Handle transient parent-entry xactions in lookup

2012-04-19T07:25:17+00:00

This patch addresses the case when the lookup on an entry is performed
while it is being renamed. The lookup can possibly return 2 different
gfids when lookup on one subvol reached before rename and on other
after rename. In such cases the conflicting entry self-heal is
triggered to resolve the issue, but if there are lot entry transactions
going on the parent directory of the entry then the non-blocking
locks could fail resulting in EIO. To avoid this, lookup queries
locks xlator if there are any parent-entrylk on entry's basename.
If afr finds that there are such locks and gfids are differing then
it chooses the file with latest ctime as the iatt of the entry.
This solution is not foolproof, but it decreases the probability of
hitting the EIO. The correct solution is to take blocking locks on
the parent-entry to find out the correct source. Taking blocking
locks in lookup is not good. One stale entry lock can hang the whole
filesystem. So we chose to go with this for now.

cli: do not put the frame->local to mempool since its a calloced structure

2012-04-19T06:53:51+00:00

In cli, frame->local is not allocated from the internal mempool, rather its
calloced. So while destroying the stack, we have to set frame->local to NULL.
Otherwise if frame->local is not NULL, STACK_DESTROY will try to put it back
to the mempool and thus segfault.
