* cluster/dht: synchronize with other concurrent healers while healing layout.Raghavendra G2015-02-205-41/+562
| | | | | | | | | | | | | | | | | | | | | | | | | | Current layout heal code assumes layout setting is idempotent. This allowed multiple concurrent healers to set the layout without any synchronization. However, this is not the case as different healers can come up with different layout for same directory and making layout setting non-idempotent. So, we bring in synchronization among healers to 1. Not to overwrite an ondisk well-formed layout. 2. Refresh the in-memory layout with the ondisk layout if in-memory layout needs healing and ondisk layout is well formed. This patch can synchronize 1. among multiple healers. 2. among multiple fix-layouts (which extends layout to consider added or removed brick) 3. (but) not between healers and fix-layouts. So, the problem of in-memory stale layouts (not matching with layout ondisk), is not _completely_ fixed by this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Renaming directories can cause the size of the buffer required for posix_handle_path to increase between the first call, which calculates the size, and the second call which forms the path in the buffer allocated based on the size calculated in the first call. The path created in the second call overflows the allocated buffer and overwrites the stack causing the brick process to crash. The fix adds a buffer size check to prevent the buffer overflow. It also checks and returns an error if the posix_handle_path call is unable to form the path instead of working on the incomplete path, which is likely to cause subsequent calls using the path to fail with ELOOP.

* cluster/dht: Fix dht_link to follow files under migrationShyam2015-02-171-19/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if a file is under migration, a hardlink to that file is lost post migration of the file. This is due to the fact that the hard link is created against the cached subvol of the source and as the source is under migration, it shifts to a linkto file post migration. Thus losing the hardlink. This change follows the stat information that triggers a phase1/2 detection for a file under migration, to create the link on the new subvol that the source file is migrating to. Thereby preserving the hard link post migration. NOTES: The test case added create a ~1GB file, so that we can catch the file during migration, smaller files may not capture this state and the test may fail. Even if migration of the file fails, we would only be left with stale linkto files on the subvol that the source was migrating to, which is not a problem. This change would create a double linkto, i.e new target hashed subvol would point to old source cached subol, which would point to the real cached subvol. This double redirection although not handled directly in DHT, works as lookup searches everywhere on hitting linkto files. The downside is that it never heals the new target hashed subvol linkto file, which is another bug to be resolved (does not cause functional impact).

| | | | | | | | | | | | | | | | | | | Normally a named-lookup is done by the kernel on an entry before it issues a dentry creation fop like create/mknod etc. This will enable cluster translators like dht to maintain internal consistency like deleting a linkto file if no corresponding datafile is present etc. While handling file creation on auxiliary gfid mounts, we issue dentry creation fop without issuing a lookup. If there are stale-linkto files, creation would fail with EEXIST, however access would fail since there is no datafile. A named lookup would cleanup the linkto file allowing create to succeed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ... from all bricks in the volume This patch is important in the context of MT epoll. With MT epoll, notification events from client xlators could reach cluster xlators like afr, dht, ec, stripe etc. in different orders. For e.g, In a distributed replicate volume of 2 bricks, namely Brick1 and Brick2, the following network events are observed by a mount process. - connection to Brick1 is broken. - connection to Brick1 has been restored. - connection to Brick2 is broken. - connection to Brick2 has been restored. Without establishing a total ordering of events, we can't guarantee that cluster xlators like afr, dht perceive them in the same order. While we would expect afr (say) to perceive it as only one of Brick1 and Brick2 going down at any given time, it is possible for the notification of Brick2 going offline to race with the notification of Brick1 coming back online.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to configure the number of event threads for various gluster services. Currently with the multi thread epoll patch, it is possible to have more than one thread waiting on socket activity and processing the same. This thread count is currently static, which this commit makes dynamic. The current services which use IO path, i.e brick processes, any client process (nfs, FUSE, gfapi, heal, rebalance, etc.a), gain 2 set parameters to control the number of threads that are processing events. These settings are, - client.event-threads <n> - server.event-threads <n> The client setting affects the client graph consumers, and the server setting affects the brick processes. These are processed and inited/reconfigured using the client/server protocol xlators. Other services (say glusterd) would need to extend similar configuration settings to take advantage of multi threaded event processing. At present glusterd is not enabled with this commit, as it does not stand to gain from this multi-threading (as I understand it).

| | | | | | | | | | | | | | | | | | | | Problem: When data-self-heal-algorithm is set to 'full', shd just reads from source and writes to sink. If source file happened to be sparse (VM workloads), we end up actually writing 0s to the corresponding regions of the sink causing it to lose its sparseness. Fix: If the source file is sparse, and the data read from source and sink are both zeros for that range, skip writing that range to the sink.

* ec: Fix posix compliance failuresXavier Hernandez2015-01-286-87/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch solves some problems that caused dispersed volumes to not pass posix smoke tests: * Problems in open/create with O_WRONLY Opening files with -w- permissions using O_WRONLY returned an EACCES error because internally O_WRONLY was replaced with O_RDWR. * Problems with entrylk on renames. When source and destination were the same, ec tried to acquire the same entrylk twice, causing a deadlock. * Overwrite of a variable when reordering locks. On a rename, if the second lock needed to be placed at the beggining of the list, the 'lock' variable was overwritten and later its timer was cancelled, cancelling the incorrect one. * Handle O_TRUNC in open. When O_TRUNC was received in an open call, it was blindly propagated to child subvolumes. This caused a discrepancy between real file size and the size stored into trusted.ec.size xattr. This has been solved by removing O_TRUNC from open and later calling ftruncate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: Gathering iatts from ONLY the hashed subvol during MKDIR and unwinding them can cause md-cache to cache and serve these values for a while to the application. And then, at a later point of time, when a LOOKUP on either the dir or its parent gathers attributes from all subvolumes of dht and things are evened out as part of DHT_UPDATE_TIME, the application could be getting a different set of [cm]times (i.e., one of the non-hashed subvolumes' times could be selected by virtue of having the highest values), causing it to think the directory underwent modification even when it might not have. The effect of this bug becomes apparent in programs like tar, which rely on the ctime of the files before and after archiving a file to ascertain that the file remained unchanged during this time. FIX: Aggregate iatts from ALL sub-volumes of DHT during MKDIR.

* geo-rep: Handle copying of common_secret.pem.pub to slave correctly.Kotresh HR2015-01-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current Behaviour: 1. Geo-replication gsec_create creates common_secret.pem.pub file containing public keys of the all the nodes of master cluster in the location /var/lib/glusterd/ 2. Geo-replication create push-pem copies the common_secret.pem.pub to the same location on all the slave nodes with same name. Problem: Wrong public keys might get copied on to slave nodes in multiple geo-replication sessions simultaneosly. E.g. A geo-rep session is established between Node1(vol1:Master) to Node2 (vol2:Slave). And one more geo-rep session where Node2 (vol3) becomes master to Node3 (vol4) as below. Session1: Node1 (vol1) ---> Node2 (vol2) Session2: Node2 (vol3) ---> Node3 (vol4) If steps followed to create both geo-replication session is as follows, wrong public keys are copied on to Node3 from Node2. 1. gsec_create is done on Node1 (vol1) -Session1 2. gsec_create is done on Node2 (vol3) -Session2 3. create push-pem is done Node1 - Session1. -This overwrites common_secret.pem.pub in Node2 created by gsec_create in second step. 4. create push-pem on Node2 (vol3) copies overwrited common_secret.pem.pub keys to Node3. -Session2 Consequence: Session2 fails to start with Permission denied because of wrong public keys Solution: On geo-rep create push-pem, don't copy common_secret.pem.pub file with same name on to all slave nodes. Prefix master and slave volume names to the filename. NOTE: This brings change in manual steps to be followed to setup non-root geo-replication (mountbroker). To copy ssh public keys, extra two arguments needs to be followed. set_geo_rep_pem_keys.sh <mountbroker_user> <master vol name> \ <slave vol name> Path to set_geo_rep_pem_keys.sh: Source Installation: /usr/local/libexec/glusterfs/set_geo_rep_pem_keys.sh Rpm Installatino: /usr/libexec/glusterfs/set_geo_rep_pem_keys.sh Change-Id: If38cd4e6f58d674d5fe2d93da15803c73b660c33 BUG: 1183229 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/9460 Reviewed-by: Aravinda VK <avishwan@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Venky Shankar <vshankar@redhat.com> Tested-by: Venky Shankar <vshankar@redhat.com>
