* afr: pass back xdata in createBrian Foster2012-07-231-2/+5
| | | | | | | | | | | | | | | A striped, replicated volume spits an error on file creation because stripe requires xdata to process stripe information and AFR isn't passing it back. This fix was suggested by Amar Tumballi.

* cluster/afr: post-op-delay supportAnand Avati2012-07-046-2/+175
| | | | | | | | | | | | | | | | post-op-delay introduces an artificial delay between the OP and POST-OP-CHANGELOG phases of a write transaction to increase the probability of changelog-piggyback and eager-locking to work more efficiently. Also enable eager-locking by default.

* cluster/afr: cleanup lk_owner and PID messAnand Avati2012-07-043-41/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically PID (frame->root->pid) was used by the locks translator to identify a locker (and make decisions about which locks contend or cooperate/merge). Since the introduction of lock_owner parameter the usage of PID (for locks) was deprecated and is now unused. This patch nukes the usage of PID in AFR The usage of lk_owner has also ended up being a mess, because of the differentiation required between ->lk() and ->inodelk(), (->lk() needs to be identified by the process (roughly) and ->inodelk() needs to be identified by the transaction) and also because of optimizations like eager locking (locks are no more identified by the transaction as they now get inherited by the next transaction). The scheme (and technique) now is: - All FOPs (the third phase of the transaction) happen with the lk_owner which is set by the topmost layer (FUSE, NFS etc.) - All entrylks are issued with lk_owner set to the frame->root address. - Inodelks which will not be subject to eager locking are issued with lk_owner set to frame->root. - Inodelks which are subject to eager locking are issued with lk_owner set to the address of fd_t (which are the only type of frames which get subject to the eager locking optimization) - At the start of the transaction, the transaction frame's lk_owner is set to the either frame->root or fd_t (and never unmodified) depending on the type of transaction. - Just before the third phase (FOP phase) the set lk_owner is "saved" away and overwritten by the lk_owner submitted by the top layer (FUSE or NFS) - Right after the third phase, the saved lk_owner is "restored" to resume the transaction into the POST-OP and eventually UNLOCK using the same lk_owner which was used during the LOCK phase.

* cluster/afr: add a new option to select read-subvol by indexJeff Darcy2012-07-031-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | read subvolume is a nice option to set prefred read child if you have a replication over 2 datacenter. if you have 2 datacenter and have a distributed replication where one set of servers are in datacenter one and the other (the replicated) are in the other datacenter read-subvolume it not very handy since it goes over name and the subvolume name is different for each replication pair. i added a new option called read-subvolume-index which take the number of the subvolume to choose. 0 fo first , 1 for second and so on subvolume in every replication. this option can now be used in the --xlator-option mount option to choose the prefered read child for all replication at once. For Example on all clients in datacenter one you can use --xlator-option=volumename-replication-*.read-subvolume-index=0 to prefer read from the servers in datacenter one. when you expand or shrink the volume no changes are needed to the client config since the wildcard will set this option automatic on reconfigure.

* libglusterfs : Fix validation for integer volume options.Kaushal M2012-06-071-0/+1
| | | | | | | | | | | | | | | | | | | | | Integer volume options which specified only the min value as 0, would not be validated during "volume set". The range check for an option happened only if both min and max were not 0. In the above case, even though a minium was specified, the range check did not happen as both min and max were 0. To allow forced validation in such cases, a new member, "validate", has been added to volume_options_t. This member takes the values GF_OPT_VALIDATE_BOTH, GF_OPT_VALIDATE_MIN and GF_OPT_VALIDATE_MAX (GF_OPT_VALIDATE_BOTH is the default).

* replicate: add hashed read-child method.Jeff Darcy2012-05-316-18/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both the first-to-respond method and the round-robin method are susceptible to clients repeatedly choosing the same servers across a series of opens, creating hot spots. Also, the code to handle a replica being down will ignore both methods and just choose the first remaining (which is not an issue for two-way but can be otherwise). The hashed method more reliably avoids such hot spots. There are three values/modes. 0: use the old (broken) methods. 1: select a read-child based on a hash of the file's GFID, so all clients will choose the same subvolume for a file (ensuring maximum consistency) but will distribute load for a set of files. 2: select a read-child based on a hash of the file's GFID plus the client's PID, so different children will distribute load even for one file. Mode 2 will probably be optimal for most cases. Using response time when we open the file is problematic, both because a single sample might not have been representative even then and because load might have shifted in the hours or days since (for long-lived files). Trying to use more current load information can lead to "herd following" behavior which is just as bad. Pseudo-random distribution is likely to be the best we can reasonably do, just as it is for DHT.

* cluster/afr: Enforce order in pre/post opPranith Kumar K2012-05-189-100/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xattrop order in pre/post op on all the subvols is client-0, client-1... client-n where n is (replica-count - 1). This order can lead to invalid split-brains if the brick dies in the middle of xattrops. Example: transaction completed pre-op, so on all the subvolumes xattrs have '1' changelog. Now post-op is sent to both the subvols. On subvol-0 change-log of client-0 is decremented to 0, before decrementing change-log of client-1 to 0 the brick dies. This change-log status on subvol-0 gives the meaning that a change is done on subvol-0 successfully but on subvol-1 it failed. Which is not what happened. Changes done when the subvol-0 was down will lead to pending change-log on subvol-1 for subvol-0. Which is correct. When the subvol-0 is brought back up, the change-log will be in split-brain state even when it is not a legitimate split-brain. If the brick dies in the middle of xattrops it should remain fool. Pre-op should perform xattrop of the local change-log first and post-op should perform xattrop of the local change-log last. In case of optimistic changelogs txn_changelog should be done last on local if it succeeds, first if it fails.

* cluster/afr: Handle transient parent-entry xactions in lookupPranith Kumar K2012-04-192-6/+96
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
