* io-stats: Add stats for upcall notificationsv3.10devPoornima G2016-08-311-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, there will be additional entries seen in the profile info: UPCALL : Total number of upcall events that were sent from the brick(in brick profile), and number of upcall notifications recieved by client(in client profile) Cache invalidation events: ------------------------- CI_IATT : Number of upcalls that were cache invalidation and had one of the IATT_UPDATE_FLAGS set. This indicates that one of the iatt value was changed. CI_XATTR : Number of upcalls that were cache invalidation, and had one of the UP_XATTR or UP_XATTR_RM set. This indicates that an xattr was updated or deleted. CI_RENAME : Number of upcalls that were cache invalidation, resulted by the renaming of a file or directory CI_UNLINK : Number of upcalls that were cache invalidation, resulted by the unlink of a file. CI_FORGET : Number of upcalls that were cache invalidation, resulted by the forget of inode on the server side. Lease events: ------------ LEASE_RECALL : Number of lease recalls sent by the brick (in brick profile), and number of lease recalls recieved by client(in client profile) Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK, CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is because, each cache invalidation can carry multiple flags. Eg: - Every CI_XATTR will have CI_IATT - Every CI_UNLINK will also increment CI_IATT as link count is an iatt attribute. Also UP_PARENT_DENTRY_FLAGS is currently not accounted for, as CI_RENAME and CI_UNLINK will always have the flag UP_PARENT_DENTRY_FLAGS Change-Id: Ieb8cd21dde2c4c7618f12d025a5e5156f9cc0fe9 BUG: 1371543 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15193 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
* glusterd : Introduce reset brickAnuradha Talur2016-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* glusterd/cli: cli to get local state representation from glusterdSamikshan Bairagya2016-08-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no existing CLI that can be used to get the local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The CLI added has the following usage: # gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>] This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (no other daemons are supported as of now) to a file inside the specified output directory. The default output directory and filename is /var/run/gluster and glusterd_state_<timestamp> respectively. The option for specifying the daemon name leaves room to add support for other daemons in the future. Following are the data points captured as of now to represent the state from the local glusterd pov: * Peer: - Primary hostname - uuid - state - connection status - List of hostnames * Volumes: - name, id, transport type, status - counts: bricks, snap, subvol, stripe, arbiter, disperse, redundancy - snapd status - quorum status - tiering related information - rebalance status - replace bricks status - snapshots * Bricks: - Path, hostname (for all bricks these info will be shown) - port, rdma port, status, mount options, filesystem type and signed in status for bricks running locally. * Services: - name, online status for initialised services * Others: - Base port, last allocated port - op-version - MYUUID Change-Id: I4a45cc5407ab92d8afdbbd2098ece851f7e3d618 BUG: 1353156 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/14873 Reviewed-by: Avra Sengupta <asengupt@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* changelog/rpc: Fix rpc_clnt_t mem leaksKotresh HR2016-07-222-6/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: 1. Freeing up rpc_clnt object might lead to crashes. Well, it was not a necessity to free rpc-clnt object till now because all the existing use cases needs to reconnect back on disconnects. Hence timer code was not taking ref on rpc-clnt object. Glusterd had some use-cases that led to crash due to ping-timer and they fixed only those code paths that involve ping-timer. Now, since changelog has an use-case where rpc-clnt need to be freed up, we need to fix timer code to take refs 2. In changelog, because of issue 1, only mydata was being freed which is incorrect. And there are races where rpc-clnt object would access the freed mydata which would lead to crashes. Since changelog xlator resides on brick side and is long living process, if multiple libgfchangelog consumers register to changelog and disconnect/reconnect mulitple times, it would result in leak of 'rpc-clnt' object for every connect/disconnect. SOLUTION: 1. Handle ref/unref of 'rpc_clnt' structure in timer functions properly. 2. In changelog, unref 'rpc_clnt' in RPC_CLNT_DISCONNECT after disabling timers and free mydata on RPC_CLNT_DESTROY. RPC SETUP IN CHANGELOG: 1. changelog xlator initiates rpc server say 'changelog_rpc_server' 2. libgfchangelog initiates one rpc server say 'libgfchangelog_rpc_server' 3. libgfchangelog initiates rpc client and connects to 'changelog_rpc_server' 4. In return changelog_rpc_server initiates a rpc client and connects back to 'libgfchangelog_rpc_server' REF/UNREF HANDLING IN TIMER FUNCTIONS: Let's say rpc clnt refcount = 1 1. Take the ref before reigstering callback to timer queue >>>> rpc_clnt_ref (say ref count becomes = 2) 2. Register a callback to timer say 'callback1' 3. If register fails: >>>> rpc_clnt_unref (ref count = 1) 4. On timer expiration, 'callback1' gets called. So unref rpc clnt at the end in 'callback1'. This is corresponding to ref taken in step 1 >>>> rpc_clnt_unref (ref count = 1) 5. The cycle from step-1 to step-4 continues....until timer cancel event happens 6. timer cancel of say 'callback1' If timer cancel fails: Do nothing, Step-4 would have unrefd If timer cancel succeeds: >>>> rpc_clnt_unref (ref count = 1) Change-Id: I91389bc511b8b1a17824941970ee8d2c29a74a09 BUG: 1316178 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/13658 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | lk_flags from posix_lock_t structure is the primary key used to differentiate locks as either advisory and mandatory type. During lock migration this field is not read in getactivelk() call path.

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-042-41/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: when bind-insecure is 'off', all the clients bind to secure ports, if incase all the secure ports exhaust the client will no more bind to secure ports and tries gets a random port which is obviously insecure. we have seen the client obtaining a port number in the range 49152-65535 which are actually reserved as part of glusterd's pmap_registry for bricks, hence this will lead to port clashes between client and brick processes. Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low in the rhgs Env, but that's a different story on its own, which will be handled in upcoming patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Moving the enumeration of FOPs and some of the other parts that are defining the network protocol to the rpc/xdr/ section. These structures need some care when modifications are made, moving them out of the common glusterfs.h header helps with that. The protocol definition structures are generated in a new glusterfs-fops header. This file is present in rpc/xdr/src/ and libglusterfs/src/, it is a little ugly, but prevents the need to update all Makefile.am files with the additional -I option for finding the new header file. The generation of the .c and .h files from the .x descriptions needed small modifications to accommodate these changes. The build/xdrgen script was improved slightly for this. The .c and .h files are incorrectly in the $(top_srcdir), instead of $(top_builddir). This is an existing issue, and bug 1330604 has been filed to get that addressed.

* socket: Don't cleanup encrypted transport in socket_connect()Kaushal M2016-04-071-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ..instead cleanup only in socket_poller() With commit d117466 socket_poller() wasn't launched from socket_connect (for encrypted connections), if connect() failed. This was done to prevent the socket private data from being double unreffed, from the cleanups in both socket_poller() and socket_connect(). This allowed future reconnects to happen successfully. If a socket reconnects is sort of decided by the rpc notify function registered. The above change worked with glusterd, as the glusterd rpc notify function (glusterd_peer_rpc_notify()) continuously allowed reconnects on failure. mgmt_rpc_notify(), the rpc notify function in glusterfsd, behaves differently. For a DISCONNECT event, if more volfile servers are available or if more addresses are available in the dns cache, it allows reconnects. If not it terminates the program. For a CONNECT event, it attempts to do a volfile fetch rpc request. If sending this rpc fails, it immediately terminates the program. One side effect of commit d117466, was that the encrypted socket was registered with epoll, unintentionally, on a connect failure. A weird thing happens because of this. The epoll notifier notifies mgmt_rpc_notify() of a CONNECT event, instead of a DISCONNECT as expected. This causes mgmt_rpc_notify() to attempt an unsuccessful volfile fetch rpc request, and terminate. (I still don't know why the epoll raises the CONNECT event) Commit 46bd29e fixed some issues with IPv6 in GlusterFS. This caused address resolution in GlusterFS to also request of IPv6 addresses (AF_UNSPEC) instead of just IPv4. On most systems, this causes the IPv6 addresses to be returned first. GlusterD listens on 0.0.0.0:24007 by default. While this attaches to all interfaces, it only listens on IPv4 addresses. GlusterFS daemons and bricks are given 'localhost' as the volfile server. This resolves to '::1' as the first address. When using management encryption, the above reasons cause the daemon processes to fail to fetch volfiles and terminate. Solution -------- The solution to this is simple. Instead of cleaning up the encrypted socket in socket_connect(), launch socket_poller() and let it cleanup the socket instead. This prevents the unintentional registration with epoll, and socket_poller() sends the correct events to the rpc notify functions, which allows proper reconnects to happen.

* protocol client/server: Fix client-server handshakeAvra Sengupta2016-03-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently on a successful connection between protocol server and client, the protocol client initiates a CHILD_UP event in the client stack. At this point in time, only the connection between server and client is established, and there is no guarantee that the server side stack is ready to serve requests. It works fine now, as most server side translators are not dependent on any other factors, before being able to serve requests today and hence they are up by the time the client stack translators receive the CHILD_UP (initiated by client handshake). The gap here is exposed when certain server side translators like NSR-Server for example, have a couple of protocol clients as their child(connecting them to other bricks), and they can't really serve requests till a quorum of their children are up. Hence these translators should defer sending CHILD_UP till they have enough children up, and the same needs to be propagated to the client stack translators. Fix: Maintain a child_up variable in both the protocol client and protocol server translators. The protocol server should update this value based on the CHILD_UP and CHILD_DOWN events it receives from the translators below it. On receiving such an event it should forward that event to the client. The protocol client on receiving such an event should forward it up the client stack, thereby letting the client translators correctly know that the server is up and ready to serve. The clients connecting later(long after a server has initialized and processed it's CHILD_UP events), will receive a child_up status as part of the handshake, and based on the status of the server's child_up, can either propagate a CHILD_UP event or defer it.

| | | | | | | | | | | | | | | | | | | | This is to fix regression caused by below patch - http://review.gluster.org/#/c/13456/ As discussed over http://thread.gmane.org/gmane.comp.file-systems.gluster.devel/14284, patch #13456 caused a regression where in if there are any pending rpc invocations, we end up accessing freed object. This patch fixes it by allowing reconnect during rpc submit only if rpc is not disabled.

* socket: Launch socket_poller only if connect succeededKaushal M2016-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | For an encrypted connection, sockect_connect() used to launch socket_poller() in it's own thread (ON by default), even if the connect failed. This would cause two unrefs to be done on the transport, once in socket_poller() and once in socket_connect(), causing the transport to be freed and cleaned up. This would cause further reconnect attempts from failing as the transport wouldn't be available. By starting socket_poller() only if connect succeeded, this is avoided.

* rpc: Fix for rpc_transport_t leakSoumya Koduri2016-02-231-2/+3
| | | | | | | | | | | | | | | | | | | | The transport object needs to get unref'ed when the rpc clnt object is getting destroyed. But currently in rpc_clnt_disable() we set conn->trans to NULL before it gets unref'ed leading to transport object leak. This change is to fix it by setting conn-tran to NULL only when it is being unref'ed.
