* 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/distribute: handle dht_layout_normalize errors differently inRaghavendra G2012-04-232-15/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | dht_lookup_dir_cbk and dht_discover_complete. return value from dht_layout_normalize is interpreted as follows: ret > 0 - number of subvolumes returned ENOENT errors. ret = 0 - no anomalies found. ret < 0 - there are holes/overlaps. 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.

* 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.
