* glusterd: Preserve backward compatibility during sync and storeKaushal M2014-06-052-168/+386
| | | | | | | | | | | | | | | | | | | | | | | | | | The glusterd volinfo struct gained several new members to support the volume snapshot feature. These members are also being exported/imported during volume sync and being stored/restored. This export/import and save/restore explicitly required these members to be present, and would fail if they were not. This lead to the failure of backward compatibility, preventing new peers from correctly interacting with older peers (especially during a rolling upgrade). This patch contains changes needed to preserve the backward compatibility in the places specified. The snapshot members of the volinfo will now be exported/imported and stored only when the cluster op-version is >= 4, ie. all peers in the cluster support snapshot. No change is required for the restore code as, the new members will be left at the default zero values if corresponding entries are absent in the stored volinfo.

| | | | | | | | | | | | | | | A new gsyncd options '--pause-on-start' is introduced. When node reboots, if the status is paused, gsyncd is started with this option. After gsyncd spawns worker and agent, worker will send SIGSTOP to negative pid of monitor to enter pause mode.

* glusterd: Handle rpc_connect failure in the event handlerVijaikumar M2014-06-054-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rpc_connect calls the notification function on failure in the same thread, glusterd notification holds the big_lock and hence big_lock is released before rpc_connect In snapshot creation, releasing the big-lock before completeing operation can cause problem like deadlock or memory corruption. Bricks are started as part of snapshot created operation. brick_start releases the big_lock when doing brick_connect and this might cause glusterd crash. There is a similar issue in bug# 1088355. Solution is let the event handler handle the failure than doing it in the rpc_connect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | for individual snapshots for snapshot status Problem : Initially, we used to do all the calculation in the glusterd side, once all the information related to snap was fetched, it was aggregated into one dictionary and that was sent back to CLI. Problem with this approach was, when number of snapshots are very high then CLI will timeout. Solution: First fetch snapcount and snapname from glusterd, then make a individual calls using the snapname fetched. This will resolve the timeout problem.

On a non-root setup, Gluster CLI would run as an unprivileged user, failing to execute the command. As a workaround (for testing), setuid(2) Gluster CLI executable or use the glusterd option to accept commands by unprivileged CLI process. The nature of cli commands are "system::" commands (for key management) and remote volume info fetching. Remote volume info fetching has been modified to use --remote-host gluster cli option rather than ssh and remote cli execution.

| | | | | | | | | | | | | | | | | | | | | | | | perform snapshot status command. Problem : Snapshot status command used to fail as it used to hit the quorum check path. Solution : The condition checking where snapname is fetched based on the presence of snap_volume is moved inside create switch case. And also moved the chunk of code which does the actual quorum check to new function to make the code more readable.

* glusterd: On gaining quorum spawn_daemons in new threadKaushal M2014-05-124-28/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | During startup, if a glusterd has peers, it waits till quorum is obtained to spawn bricks and other services. If peers are not present, the daemons are started during glusterd' startup itself. The spawning of daemons as a quorum action was done without using a seperate thread, unlike the spawn on startup. Since, quotad was launched using the blocking runner_run api, this leads to the thread being blocked. The calling thread is almost always the epoll thread and this leads to a deadlock. The runner_run call blocks the epoll thread waiting for quotad to start, as a result glusterd cannot serve any requests. But the startup of quotad is blocked as it cannot fetch the volfile from glusterd. The fix for this is to launch the spawn daemons task in a seperate thread. This will free up the epoll thread and prevents the above deadlock from happening.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glfs object. Defined new APIs in the libgfapi module, given a glfs object, * to send handshake RPC call to glusterd process to fetch UUID of the volume * store it in the glusterfs_context linked to the glfs object. * to parse UUID from its cannonical string format into 16-byte array before sending it to the libgfapi users. Defined a RPC call in glusterd which can be used to query volume related info by other processes using 'clnt_handshake_procs'. Note - Currently this RPC call to glusterd process is used only to fetch UUID. But it can be extended to get other volume related structures as well. In addition to the above, defined a new variable to keep track of such handshake RPCs still in progress to make sure all the corresponding RPC callbacks have been processed before libgfapi returns the glfs object initialized. Also bumping up the GFAPI current version number since there is a new API "glfs_get_volume_id" defined and exposed by libgfapi as part of these changes.

* rpc: implement server.manage-gids for group resolving on the bricksNiels de Vos2014-05-092-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | The new volume option 'server.manage-gids' can be enabled in environments where a user belongs to more than the current absolute maximum of 93 groups. This option triggers the following behavior: 1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or libgfapi) will contain only one (1) auxiliary group, instead of a full list. This reduces network usage and prevents problems in encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes. 2. The single group in the RPC Calls received by the server is replaced by resolving the groups server-side. Permission checks and similar in lower xlators are applied against the full list of groups where the user belongs to, and not the single auxiliary group that the client sent.

| | | | | | | | | | | | | | | | | | | | | | | | | | Releasing the big-lock can cause problem like deadlock or memory corruption. Same happened with bug 1091926 where glusterd on node-2 entered a commit phase and released a big-lock. The originator node received timeout for the commit phase and triggered a post-validate cleanup to the node-2. Now node-2 continued to work with the object that are alreday cleaned-up and resulted in a crash. Solution is to not to release big-lock in the commit phase of snapshot creation.

After this, the glusterd responds back with the specfile. Also collate brick data from the node's hosting the bricks during restore. In case the data is absent, the local node's data is used. This is needed to ensure that, during a restore we collect the information created when a missed snap create is performed.
