cluster/afr: Perform delayed changelog wakeups for anon fd

2013-06-20T08:44:37+00:00

Problem:
Nfs xlator never does open on a file for performing writes,
afr does not perform changelog wakeup for this fd so operations
which do metadata operations as soon as the data operations are
completed perceive a delay of 'post-op-delay-secs'.

Fix:
Perform changelog wakeup on anon-fd if the fd with same pid is
not present in inode-list.

Note:
This approach is a short-term fix. A proper fix needs a new domain
for taking metadata locks so that data/metadata locks don't compete
with each other.

fd: filter anonymous FD from fd_lookup() result

2013-01-29T00:44:51+00:00

Those callers whose requirements can accommodate an anonymous FD
need to call fd_anonymous(). fd_lookup() is strictly for open()ed
file descriptors only.

Do not dump the entire inode table in the statedump. Instead dump
those inodes only which are present in fdtable or ltable.

libglusterfs/fd: while dumping the fd_ctx use fd->xl_count

2012-05-17T10:49:55+00:00

While dumping the fd_ctx when statedump is issued fd->xl_count should be
used to determine the number of xlators instead of using latest graph's count,
since while creating the fd only those many slots would have been allocated
as the number of xlators in the graph at that instant. Then the graph would have
changed, thus the xl count.

All the above things should happen before any operation is done on fd, otherwise
fd_ctx_set will allocate the extra slots for the new xlators present in the
graph.

Also added the program which can be used to reproduce the bug.
