* 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.

* libgfapi: Added support to fetch volume info from glusterd and store in ↵Soumya Koduri2014-05-117-8/+445
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vos2014-05-098-14/+248
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* glusterd : Volname, brickpath & volfpath length validationAtin Mukherjee2014-05-0310-24/+152
| | | | | | | | | | | | | | | | | | | | | | | | While creating a volume and adding a brick validation for _POSIX_PATH_MAX is done on absolute pathname instead of relative pathname due to which a brickpath having less than _POSIX_PATH_MAX may also fail the validation if the directory length is greater than (_POSIX_PATH_MAX -strlen(brickpath/volume name). Also this fix addresses one cli response message correction which says the volume file is too long instead of brick path is too long (when brickpath length validation doesn't fail and vol file length validation fails.) It is also important to note that with the current design of volfile naming, it can not be guranteed that volname and brickpath can have max of _POSIX_PATH_MAX characters.

* barrier : fsync call over NFS should be barriered when barrier is enabledAtin Mukherjee2014-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | barrier_fsync was not getting hit when fsync call is issued from the application over NFS mount. Investigation reveals that NFS doesn't send an explicit fsync call to the glusterfs server, however NFS converts it with a stable write with O_DSYNC flag, so for a fsync call over NFS mount point, barrier feature always needs to check for writev and its correspoding flags. So to meet all the coditions of write with O_SYNC and fsync getting blocked when barrier is enabled the check has been modified with following: if (!((flags | fd->flags) & (O_SYNC | O_DSYNC))) Point to be noted here is we need to check both fd's flag and the explicit flag as for NFS write fd->flags is 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. gluster volume set nfs-ganesha.enable ON/OFF If the option is set to ON, the volume field in the nfs-ganesha configuartion file is edited. Gluster-nfs is disabled on that volume and the volume is exported using nfs-ganesha. 2.gluster volume set nfs-ganesha.host IP This is used to provide the IP of the nfs-ganesha host. Note : nfs-ganesha.host MUST be set before using nfs-ganesha.enable ON The switch from gluster-nfs to nfs-ganesha is mostly done by the hook-scripts in the post phase of the 'set' option. As a result, gluster volume reset does not function as it is expected to. By default, nfs-ganesha will be set to off but the process will not be killed. Hence, a few changes have to be made post 'reset' option as well. Those changes also have been added.

| | | | | | | | | | | | | | | | | | | | | | | | | We had added %P in the value for path in smb share definitions to avoid ctdb errors. However, %P does not work well for windows clients and they fail to access the share. Solution for the original problem: The error messages were being generated by a monitoring script that ctdb runs. The script reads the path value from testparm and tests if it exists in the local machine. This particular check does not hold valid for virtual file system backends like gluster. There is no harm in asking ctdb to not to check the existence of such backend and can be done by setting the following config in ctdb.conf: CTDB_SAMBA_SKIP_SHARE_CHECK=YES.
