* cluster/afr: Allow data/entry self heal for metadata split-brainVenkatesh Somyajulu2013-07-021-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently whenever there is metadata split-brain, a variable sh->op_failed is set to 1 to denote that self heal got failed. But if we proceed for data self heal, even code-path of data self heal also relies on the sh->op_failed variable. So if will check for sh->op_failed variable and will eventually fails to do data self heal. So needed a mechanism to allow data self heal even if metadata is in split brain. Fix: Some data structure revamp is done in http://review.gluster.com/#/c/5106/ fix and this patch is based on the above fix. Now we can store which particular self-heal got failed i.e GFID_OR_MISSING_ENTRY_SELF_HEAL, METADATA, DATA, ENTRY. And we can do two types of self heal failure check. 1. Individual type check: We can check which among all four (Metadata, Data, Gfid or missing entry, entry self heal) got failed. 2. In afr_self_heal_completion_cbk, we need to make check based on the fact that if any specific self heal got failed treat the complete self heal as failure so that it will populate corresponding circular buffer of event history accordingly.

* nfs: Remove afr split-brain handling in nfsPranith Kumar K2013-06-251-0/+12
| | | | | | | | | | | | | | | | We added this code as an interim fix until afr can handle split-brains even when opens are not issued. Afr code has matured to reject fd based fops when there are split-brains so we can remove it.

* dht: better layout-optimization algorithmJeff Darcy2013-02-071-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
