* cluster/dht: In MKDIR(), aggregate iatts from non-hashed subvols tooKrutika Dhananjay2015-01-231-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | When command 'clear-locks' from cli is executed, a getxattr request is received by ec. This request was handled as usual, first locking the inode. Once this request was processed by the bricks, all locks were removed, including the lock used by ec. When ec tried to unlock the previously acquired lock (which was already released), caused a crash in glusterfsd. This fix executes the getxattr request without any lock acquired for the clear-locks command.

| | | | | | | | | | | | | | | | | | | Allowing O_APPEND flag to pass through to the brick files corrupts fragment contents because writes are not stored on the desired place. Write fop has been modified so that it uses current file size as its write offset. This guarantees that all writes, even those comming from different file descriptors and clients, will write to the end of the file.

Setting this virtual setxattr on directories captures MKDIR in changelog. The value of setxattr can be as follows. If value = "1" : Both CREATE and DATA is captured in changelog if pargfid is available, else on DATA is captured. value = "any other: ENOTSUP is returned. Usage: setfattr -n glusterfs.geo-rep.trigger-sync -v "1" <file-path> NOTE: This patch supports explicit record of entries only for directories and regular files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Afr winds inodelk calls without any order, so blocking inodelks from two different mounts can lead to dead lock when mount1 gets the lock on brick-1 and blocked on brick-2 where as mount2 gets lock on brick-2 and blocked on brick-1 Fix: Serialize the inodelks whether they are blocking inodelks or non-blocking inodelks. Non-blocking locks also need to be serialized. Otherwise there is a chance that both the mounts which issued same non-blocking inodelk may endup not acquiring the lock on any-brick. Ex: Mount1 and Mount2 request for full length lock on file f1. Mount1 afr may acquire the partial lock on brick-1 and may not acquire the lock on brick-2 because Mount2 already got the lock on brick-2, vice versa. Since both the mounts only got partial locks, afr treats them as failure in gaining the locks and unwinds with EAGAIN errno.

* afr: stop encoding subvolume id in readdir d_offAnand Avati2014-12-263-131/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of encoding d_off in AFR is to indicate the selected subvolume for the first readdir, and continue all further readdirs of the session on the same subvolume. This is required because, unlike files, dir d_offs are specific to the backend and cannot be re-used on another subvolume. The d_off transformation encodes the subvolume id and prevents such invalid use of d_offs on other servers. However, this approach could be quite wasteful of precious d_off bit-space. Unlike DHT, where server id can change from entry to entry and thus encoding the server id in the transformed d_off is necessary, we could take a slightly relaxed approach in AFR. The approach is to save the subvolume where the last readdir request was sent in the fd_ctx. This consumes constant space (i.e no per-entry cache), and serves the purpose of avoiding d_off "misuse" (i.e using d_off from one server on another). The compromise here is NFS resuming readdir from a non-0 cookie after an extended delay (either anonymous FD has been reclaimed, or server has restarted). In such cases a subvolume is picked freshly. To make this fresh picking more deterministic (i.e, to pick the same subvolume whenever possible, even after reboots), the function afr_hash_child (used by afr_read_subvol_select_by_policy) is modified to skip all dynamic inputs (i.e PID) for the case of directories.
