* feature/changelog: Capture path for deletesKotresh HR2015-05-047-6/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: There is no way to get the path of deleted file if we have gfid from changelog since the file is already deleted. SOLUTION: Do a recursive readlink on parent gfid in backend .glusterfs path to get the complete path in I/O callpath in changelog translator and capture it in callback. The path captured is relative from the brick root. The field separator used is '\0'. e.g., ......\0<pgfid>/bname\0<relative-path>\0<next-record> ADDITIONAL REQUIRED CHANGES: 1. The changelog translator option called "changelog.capture-del-path" is introduced to enable or disable the capturing of deleted entry path. e.g., gluster vol set <vol-name> changelog.capture-del-path on/off If capture-del-path is disabled, '\0' is captured instead of relative path. e.g., ......\0<pgfid>/bname\0\0\0<next-record> 2. The minor number in the version of changelog is bumped up from v1.1 to v1.2. 3. If recursive readlink is failed for some reason, it will capture \0 in place of <relative path>. e.g., ......\0<pgfid>/bname\0\0\0<next-record> (same as when caputre-del-path option is disabled) 4. If bname argument passed to "resolve_pargfid_to_path" function is NULL and pargfid is ROOT, "." is returned. This is not the case with changelog, where bname is always passed. This is applicable to other consumers of "resolve_pargfid_to_path" routine. NOTE: Changelog parser should consider the above new changes and should parse accordingly.

* rpc: Maintain separate xlator pointer in 'rpcsvc_state'Kotresh HR2015-05-044-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The structure 'rpcsvc_state', which maintains rpc server state had no separate pointer to track the translator. It was using the mydata pointer itself. So callers were forced to send xlator pointer as mydata which is opaque (void pointer) by function prototype. 'rpcsvc_register_init' is setting svc->mydata with xlator pointer. 'rpcsvc_register_notify' is overwriting svc->mydata with mydata pointer. And rpc interprets svc->mydata as xlator pointer internally. If someone passes non xlator structure pointer to rpcsvc_register_notify as libgfchangelog currently does, it might corrupt mydata. So interpreting opaque mydata as xlator pointer is incorrect as it is caller's choice to send mydata as any type of data to 'rpcsvc_register_notify'. Maintaining two different pointers in 'rpcsvc_state' for xlator and mydata solves the issue.

* features/changelog: Consider only changelog on/off as changelog breakageKotresh HR2015-05-024-11/+211
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, both chagelog on/off and brick restart were considered to be changelog breakage and treated as changelog not being continuous. As a result, new HTIME.TSTAMP file was created on both the above cases. Now the change is made such that only on changelog enable/disable, the changelog is considered to be discontinuous. New HTIME.TSTAMP file is not created on brick restart, the changelogs files are appended to last HTIME.TSTAMP file. Treating changelog as continuous in above scenario is important as changelog history API will fail otherwise. It can successfully get changes between start and end timestamps only when changelog is continuous (Changelogs in single HTIME.TSTAMP file are treated as continuous). Without this change, changelog history API would fail, and it would become necessary to fallback to other mechanisms like xsync FSCrawl in case geo-rep to detect changes in this time window. But Xsync FSCrawl would not be applicable to other consumers like glusterfind. Rationale: 1. In plain distributed volume, if brick goes down, no I/O can happen onto the brick. Hence changelog is intact with data on disk. 2. In distributed replicate volume, if brick goes down, since self-heal traffic is captured in changelog. Eventually, I/O happened whend brick down is captured in changelog.

As a result the frame->root->pid is not set. Solution: When the file is getting migrated, we get a tiering.migration key_value in the xattr dict, so that we pass this dic key-value when we do syncop_setxattr() to do data migration and set the frame->root->pid GF_CLIENT_PID_TIER_DEFRAG in dht_setxattr() just before calling dht_start_rebalance_task().

This translates to teardown cluster. All the above problems are fixed by checking the global key and value, depending on the value, specific functions are called. And also, functions related to global commands are moved to cli-cmd-global.c Commit phase of features.ganesha enable/disable runs the ganesha-ha.sh setup/teardown respectively. Before the script begins, it is important that the NFS-Ganesha service starts on all the HA nodes. Having the start service commands in the commit phase could lead to problems.

* glusterd: Use uint32_t for peerinfo generation numberKaushal M2015-04-304-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Using a uint64_t for the peerinfo generation number was overkill for how the generation number is used within GlusterD. It also prevented GlusterD from running on 32-bit architechtures, as uatomic_add_return doesn't support 64-bit values on 32-bit architechtures. This change was developed on the git branch at [1].

When two threads execute in parallel in dht_getxattr_cbk it may so happen that, both may find local->xattr to be NULL. As a result dht_aggregate_xattr may not get executed. 2. In dht_getxattr_cbk, thread1 thread2 T1 this_call_cnt = 2 -1 T2 this_call_cnt = 1 - 1 T3 fills local_xattr T4 DHT_STACK_UNWIND -> local_wipe T5 tries to dereference local which is already freed, leading to crash. Solution: for problem1: Execute critical section inside frame lock to resolve race. for problem2: Calculate this_call_count just before out section.

* rebalance: Introducing local crawl and parallel migrationSusant Palai2015-04-296-248/+1121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current patch address two part of the design proposed. 1. Rebalance multiple files in parallel 2. Crawl only bricks that belong to the current node Brief design explanation for the above two points. 1. Rebalance multiple files in parallel: ------------------------------------- The existing rebalance engine is single threaded. Hence, introduced multiple threads which will be running parallel to the crawler. The current rebalance migration is converted to a "Producer-Consumer" frame work. Where Producer is : Crawler Consumer is : Migrating Threads Crawler: Crawler is the main thread. The job of the crawler is now limited to fix-layout of each directory and add the files which are eligible for the migration to a global queue in a round robin manner so that we will use all the disk resources efficiently. Hence, the crawler will not be "blocked" by migration process. Producer: Producer will monitor the global queue. If any file is added to this queue, it will dqueue that entry and migrate the file. Currently 20 migration threads are spawned at the beginning of the rebalance process. Hence, multiple file migration happens in parallel. 2. Crawl only bricks that belong to the current node: -------------------------------------------------- As rebalance process is spawned per node, it migrates only the files that belongs to it's own node for the sake of load balancing. But it also reads entries from the whole cluster, which is not necessary as readdir hits other nodes. New Design: As part of the new design the rebalancer decides the subvols that are local to the rebalancer node by checking the node-uuid of root directory prior to the crawler starts. Hence, readdir won't hit the whole cluster as it has already the context of local subvols and also node-uuid request for each file can be avoided. This makes the rebalance process "more scalable".
