cluster/dht: Treat migration failures due to space constraints as skipped

2013-09-20T06:39:40+00:00

Currently rebalance/remove-brick op's display migration failed count even
for files which failed due to space issues (not enough space for file, or
migration leading to cluster imbalance)

These will now be counted as skipped, and rebalance/remove-brick status
will display the additional counter

cluster/afr: Don't queue transactions during open-fd fix

2013-05-09T03:52:37+00:00

Before Anonymous fds are available, afr had to queue up
transactions if the file is not opened on one of its
subvolumes. This happens until the attempt to open the
file either succeeds or fails. These attempts happen
until the file is successfully opened on the subvolume.
Now client xlator uses anonymous fds to perform the fops
if the fd used for the fop is not 'opened'.
Fops will be successful even when the file is not opened
so there is no need to queue up the transactions anymore in afr.
Open is attempted on the subvolume where it is not
opened independent of the fop.

dht: better layout-optimization algorithm

2013-02-07T16:27:40+00:00

This method deals with the case where swapping might gain a bigger overlap
for the xlator currently under consideration, but sacrifices even more from
the xlator we're swapping with. For example:

A = 0x00000000 - 0x44444443 (new 0x00000000 - 0x55555554)
B = 0x44444444 - 0x77777776 (new 0x55555555 - 0xaaaaaaa9)
C = 0x77777777 - 0xffffffff (new 0xaaaaaaaa - 0xffffffff)

Here, the new range for B has a bigger overlap with the old C than with the
old B (0x33333333 vs. 0x22222222 to be precise) so looking only at that
might lead us to swap. However, such a swap turns the new C's overlap from
0x55555556 (vs. old C) to *zero* (vs. old B).  In other words, we've gained
0x11111111 for B but lost 0x55555556 for C, so it's a bad idea.

The new algorithm accounts for all effects of the swap, so it not only avoids
bad swaps but can make some good ones that would have been missed previously.
For example, if swapping a range X with a later range Y would not increase the
overlap for X we would previously have skipped it even if the swap would
increase Y's overlap without affecting X's.  This is the normal case when we're
adding a new brick (which initially has zero overlap with any old range) so
finding more good swaps is probably even more important than avoiding bad ones.

Also, the logic in dht_overlap_calc was completely broken before, causing
integer overflows instead of providing correct values, so no matter what
higher-level algorithm was in place the GIGO effect would have resulted in
bad decisions.
