* glusterd: fix repeated connection to nfssvc failed msgsKrishnan Parthasarathi2015-05-282-13/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | ... and disable reconnect timer on rpc_clnt_disconnect. Root Cause ---------- gluster-NFS service wouldn't be started if there are no started volumes that have nfs service enabled for them. Before this fix we would initiate a connect even when the gluster-NFS service wasn't (re)started. Compounding that glusterd_conn_disconnect doesn't disable reconnect timer. So, it is possible that the reconnect timer was in execution when the timer event was attempted to be removed.

* glusterd : allocate peerid to store in frame->cookieAtin Mukherjee2015-05-283-42/+94
| | | | | | | | | | | | | | | | | | | commit a1de3b05 was using peerid from the stack and storing it in the frame->cookie and in the subsequent callback it was referred. The existance of this variable is not guranteed in the cbk since its not dynamically allocated. Fix is to dynmacially manage peerid in the frame cookie. This patch also fixes one problem in gd_sync_task_begin () where unlock is not triggered if the cluster is running with lesser than 3.6 op-version resulting into commands failing with another transaction is in progress.

* glusterd: Fix conf->generation to stop new peers participating inAvra Sengupta2015-05-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a transaction, while the transaction is in progress. Every peer gets a generation number, during it's inception. This generation number is used to identify the peer throiughout it's lifetime. This number is assigned based on the current generation number of the system, which is incremented with every peer that is added. The problem arises when we add a peer, and before it gets a rpc_connect we begin a transaction. In such a case, the peer gets considered in the transaction, but doesn't participate in it coz it isn't connected yet. The moment it gets the rpc notification and is connected, it starts participating in the transaction and all hell breaks loose. To resolve it, we should assign the peerinfo a new generation number everytime it's connected, so that this number will be greater than the generation number that the transaction is acting upon, and even though the peer is connected it will not participate in the transaction. We should also assign the new generation number of the peer to the peerctx, so that the framework that searches for peerinfos based on the generation number, will still function in the same manner.

* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-104-31/+87
| | | | | | | | | | | | | | | | | | | | | | | | The key concept here is to determine whether a directory is "clean" by comparing its last-known-good topology to the current one for the volume. These are stored as "commit hashes" on the directory and the volume root respectively. The volume's commit hash changes whenever a brick is added or removed, and a fix-layout is done. A directory's commit hash changes only when a full rebalance (not just fix-layout) is done on it. If all bricks are present and have a directory commit hash that matches the volume commit hash, then we can assume that every file is in its "proper" place. Therefore, if we look for a file in that proper place and don't find it, we can assume it's not on any other subvolume and *safely* skip the global (broadcast to all) lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | Add logic in afr to work in conjunction with the arbiter xlator when a replica 3 arbiter volume is created. More specifically, this patch: * Enables full locks for afr data transaction for such volumes. * Removes the upfront marking of pending xattrs at the time of pre-op and defer it to post-op. (This is an arbiter independent change and is made for all afr transactions.) * After pre-op stage, check if we can proceed with the fop stage without ending up in split-brain by examining the changelog xattrs. * Unwinds the fop with failure if only one source was available at the time of pre-op and the fop happened to fail on particular source brick. * Skips data self-heal if arbiter brick is the only source available. * Adds the arbiter-count option to the shd graph.

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

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. Moving the pre-requisite service start commands to the 'stage' phase.
