The current dht_fix_layout_of_directory() code, in an attempt to maximize overlap of new layout with existing layout (to minimize movement of data) fails to do a good job of randomizing new assignment even when it could do a better job. In an example where we expand from 2 nodes to 4 nodes, the current possibilities are limited in the following way - (theoretical hash range: 00 - 99) OLD 1 ----- server1: 00 - 49 server2: 50 - 99 NEW 1 ----- server1: 00 - 24 server2: 50 - 74 server3: 25 - 49 server4: 75 - 99 OLD 2 ----- server1: 50 - 99 server2: 00 - 49 NEW 2 ------ server1: 50 - 74 server2: 00 - 24 server3: 25 - 49 server4: 75 - 99 The above shows that when add-brick from 2 bricks to 4 bricks, server3 and server4 always get the _same_ hash range no matter what the original hash range assignment was. The fix in this patch is first do the standard new directory assignment to a directory (with rotation etc.) and then do the reassignment to maximize overlap. This way newly added servers still get random ranges and existing servers have a probability of getting either of the quarters which were part of its half previously. The same principles hold for all add-brick from M to M+N.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-171-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
