* core: fix errno for non-existent GFIDAnand Avati2013-11-261-0/+1
| | | | | | | | | | | | | | | | When clients refer to a GFID which does not exist, the errno to be returned in ESTALE (and not ENOENT). Even though ENOENT might look "proper" most of the time, as the application eventually expects ENOENT even if a parent directory does not exist, not returning ESTALE results in resolvers (FUSE and GFAPI) to not retry resolution in uncached mode. This can result in spurious ENOENTs during concurrent path modification operations.

* cluster/distribute: Ignore non-participating subvols for layout checksshishir gowda2013-04-111-17/+23
| | | | | | | | | | | | | | | | | | | | | | | | | Backporting fix http://review.gluster.org/#/c/4668/ When subvols-per-directory is < available subvols, then there are layouts which are not populated. This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.

* dht: better layout-optimization algorithmJeff Darcy2013-02-071-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/distribute: re-set layouts to prevent overlapsshishir gowda2012-12-111-0/+13
| | | | | | | | | | | | | | | | | 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.

We need to handle errors differently in dht_discover_cbk because, if a subvolume is newly added, the directory will not be present on it and we cannot create a directory there since a nameless lookup has resulted execution in this code-path. Hence if directory is guaranteed to be present in atleast one subvolume and there are no holes/overlaps in the layout, lookup can be treated as successful. there is no change in behaviour dht_lookup_dir_cbk caused by this patch.
