* performance/md-cache: change the op-version of "global-cache-invalidation"Raghavendra Gowdappa2019-02-121-1/+1
| | | | | | | | | Since release-6 is not done yet, this option can be introduced with GD_OP_VERSION_6_0. Change-Id: I8a0867e5b8b23d0d485704a2fc7a3efc4a90f637 Signed-off-by: Raghavendra Gowdappa <rgowdapp@redhat.com> updates: bz#1664934

* performance/md-cache: introduce an option to control invalidation of inodesRaghavendra Gowdappa2019-02-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicit invalidation by calling inode_invalidate is necessary when same (meta)data is shared/access across multiple mounts. Without an explicit inode_invalidate call, caches in the mount which didn't witness writes wouldn't be aware of changes as writes wouldn't have passed through them. However, if (meta)data is not shared, all relevant I/O goes through the cache of single mount and hence is coherent with (meta)data on bricks always. So, explicit inode invalidation can be disabled for this case which gives a huge performance boost for workloads that write data and then immediately read the data they just wrote. Note that otherwise, local writes (which pass through the cache) will change ctime and cause unnecessary invalidations. The name of the option that controls this behavior is "performance.global-cache-invalidation". This option is global and it purges caches both in glusterfs and kernel stack for native FUSE mounts. For non-native FUSE mounts, it purges cache only from glusterfs stack. This option is effective only when performance.stat-prefetch is on. Note that there is a similar option "performance.cache-invalidation", but the scope of that option is limited to quick-read and md-cache.

* glusterd: get-state command should not fail if any brick is gone badv7devSanju Rakonde2019-02-052-5/+7
| | | | | | | | | | | | | | | | | | | | | | Problem: get-state command will error out, if any of the underlying brick(s) of volume(s) in the cluster go bad. It is expected that get-state command should not error out, but should generate an output successfully. Solution: In glusterd_get_state(), a statfs call is made on the brick path for every bricks of the volumes to calculate the total and free memory available. If any of statfs call fails on any brick, we should not error out and should report total memory and free memory of that brick as 0. This patch also handles a statfs failure scenario in glusterd_store_retrieve_bricks(). fixes: bz#1672205 Change-Id: Ia9e8a1d8843b65949d72fd6809bd21d39b31ad83 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* glusterd: manage upgrade to current masterAmar Tumballi2019-02-042-12/+13
| | | | | | | | | | | | | | | | | | | | | | Scenarios tested: * Upgrade the node when there are stripe / tiering and regular type of volumes are present. - All volumes are started fine (as the change was not on brick volfile) - For tier, the functionality may not even work, as changetimerecorder is not present. - 'gluster volume info' properly shows as 'NOT SUPPORTED' for stripe and tier type of volume. * Upgrade in a rolling upgrade scenario, where an old version is able to connect to higher master. - on a normal volume, if the volfile-server was new, the newer client volfiles needed to have utime xlator conditionally. - with this one change, all other changes seem to work fine.

* features/sdfs: disable by defaultAmar Tumballi2019-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the feature enabled, some of the performance testing results, specially those which create millions of small files, got approximately 4x regression compared to version before enabling this. On master without this patch: 765 creates/sec On master with this patch : 3380 creates/sec Also there seems to be regression caused by this in 'ls -l' workload. On master without this patch: 3030 files/sec On master with this patch : 16610 files/sec This is a feature added to handle multiple clients parallely operating (specially those which race for file creates with same name) on a single namespace/directory. Considering that is < 3% of Gluster's usecase right now, it makes sense to disable the feature by default, so we don't penalize the default users who doesn't bother about this usecase. Also note that the client side translators, specially, distribute, replicate and disperse already handle the issue upto 99.5% of the cases without SDFS, so it makes sense to keep the feature disabled by default. Credits: Shyamsunder <srangana@redhat.com> for running the tests and getting the numbers.

* rpc: use address-family option from vol fileMilind Changire2019-01-222-3/+15
| | | | | | | | | | | | | | | | | This patch helps enable IPv6 connections in the cluster. The default address-family is IPv4 without using this option explicitly. When address-family is set to "inet6" in the /etc/glusterfs/glusterd.vol file, the mount command-line also needs to have -o xlator-option="transport.address-family=inet6" added to it. This option also gets added to the brick command-line. Snapshot and gfapi use-cases should also use this option to pass in the inet6 address-family.

* glusterd: fix crashSanju Rakonde2019-01-131-3/+2
| | | | | | | | | | | | | | | | | | Problem: running "gluster get-state glusterd odir /get-state" resulted in glusterd crash. Cause: In the above command output directory has been specified without "/" at the end. If "/" is not given at the end, "/" will be added to path using "strcat", so the added character "/" is not having memory allocated. When tried to free, glusterd will crash as"/" has no memory allocated. Solution: Instead of concatenating "/" to output directory, add it to output filename.

* glusterd: rebalance status should display information of localhostSanju Rakonde2019-01-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: https://review.gluster.org/#/c/glusterfs/+/21762/ has migrated rebalance commands from op-sm framework to mgmt v3 framework. In a heterogenous cluster, if rebalance commands follow op-sm framework, localhost information is not displayed in the output of "gluster v rebalance <volname> status". Cause: Previously without https://review.gluster.org/#/c/glusterfs/+/21762/ rebalance commands were following op-sm framework. In glusterd_volume_rebalance_use_rsp_dict() current_index variable keeps track of number/count of peers in trusted storage pool. In op-sm, glusterd_volume_rebalance_use_rsp_dict() will be called only for the peers. So the current index should start from 2 assuming local host as node 1. With the above patch, rebalance commands are following mgmt v3 framework. In mgmt v3, glusterd_volume_rebalance_use_rsp_dict() is called for all nodes. For localhost it is called from brick-op function and for peers it is called from brick-op call back function. So the current index value should start from 1. https://review.gluster.org/#/c/glusterfs/+/21762/ has changed the value of current index to 1. Because of this, In heterogenous cluster, local host's information is overwritten by one of the peers information. And rebalance status will not display localhost's information in the output. Solution: assign a value to current index based on a op-version check. Change-Id: I2dfba1f007e908cf160acc4a4a5d8ef672572e4d fixes: bz#1663243 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

To display information of bricks which are hosted on peers, we need to aggregate the response from peers.

To aggregate the information from peers, we need to call glusterd_syncop_aggr_rsp_dict() in brick-op call back function. fixes: bz#1663223 Change-Id: I5f5890c3d01974747f829128ab74be6071f4aa30 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* cluster/afr: Allow lookup on root if it is from ADD_REPLICA_MOUNTkarthik-us2018-12-181-1/+1
| | | | | | | | | | | | | | | | | | | | | Problem: When trying to convert a plain distribute volume to replica-3 or arbiter type it is failing with ENOTCONN error as the lookup on the root will fail as there is no quorum. Fix: Allow lookup on root if it is coming from the ADD_REPLICA_MOUNT which is used while adding bricks to a volume. It will try to set the pending xattrs for the newly added bricks to allow the heal to happen in the right direction and avoid data loss scenarios. Note: This fix will solve the problem of type conversion only in the case where the volume was mounted at least once. The conversion of non mounted volumes will still fail since the dht selfheal tries to set the directory layout will fail as they do that with the PID GF_CLIENT_PID_NO_ROOT_SQUASH set in the frame->root.

* performance/ob: make open-behind as a child of quick-readRaghavendra Gowdappa2018-12-181-9/+7
| | | | | | | | | | | | | | | | | With read-after-open being set to yes by default, if open-behind sees any reads, it'll do an open on backend (and hence flush/release later). This means with the current order of quick-read and open-behind, open-behind sees all reads and hence also does open bringing down performance for small file reads. Since for small files, reads are absorbed by quick-read, if quick-read is made a parent of open-behind, ob doesn't witness any reads. For read-only workloads, this means ob doen't do any opens (even with read-after-open yes and use-anonymous-fd no).

* glusterd: glusterd to regenerate volfiles when GD_OP_VERSION_MAX changesAtin Mukherjee2018-12-054-12/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While glusterd has an infra to allow post install of spec to bring it up in the interim upgrade mode to allow all the volfiles to be regenerated with the latest executable, in container world the same methodology is not followed as container image always point to the specific gluster rpm and gluster rpm doesn't go through an upgrade process. This fix does the following: 1. If glusterd.upgrade file doesn't exist, regenerate the volfiles 2. If maximum-operating-version read from glusterd.upgrade doesn't match with GD_OP_VERSION_MAX, glusterd detects it to be a version where new options are introduced and regenerate the volfiles. Tests done: 1. Bring up glusterd, check if glusterd.upgrade file has been created with GD_OP_VERSION_MAX value. 2. Post 1, restart glusterd and check glusterd hasn't regenerated the volfiles as there's is no change in the GD_OP_VERSION_MAX vs the op_version read from the file. 3. Bump up the GD_OP_VERSION_MAX in the code by 1 and post compilation restart glusterd where the volfiles should be again regenerated. Note: The old way of having volfiles regenerated during an rpm upgrade is kept as it is for now but eventually this can be sunset later.

| | | | | | | | | | | | | | | | libglusterfs provides wrapper functions MALLOC/__gf_default_malloc, CALLOC/__gf_default_calloc, and REALLOC/__gf_default_realloc for those few places outside of mempool.c that need to call malloc/calloc/realloc directly. Notable exceptions are "contrib" code, e.g. rbtree and timer-wheel, and perhaps parsers generated by yacc+lex. But even parsers can be fixed to at least call the wrappers mentioned above, if not our own allocators Change-Id: Ie6156307b6d2183be9c9aff153afb7598974f4e4 updates: bz#1193929 Signed-off-by: Kaleb S.

* core: fix strncpy, coverity annotationKaleb S. KEITHLEY2018-11-191-1/+6
| | | | | | | | | | | | For added fun, coverity is not smart enough to detect that the strncpy() is safe, and for extra laughs, using coverity annotations doesn't do anything either; but we're adding them anyway, along with marking the BUFFER_SIZE_WARNINGS as false positives on scan.coverity.com.

* core: fix strncpy warningsKaleb S. KEITHLE2018-11-156-42/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since gcc-8.2.x (fedora-28 or so) gcc has been emitting warnings about buggy use of strncpy. Most uses that gcc warns about in our sources are exactly backwards; the 'limit' or len is the strlen/size of the _source param_, giving exactly zero protection against overruns. (Which was, after all, one of the points of using strncpy in the first place.) IOW, many warnings are about uses that look approximately like this: ... char dest[8]; char src[] = "this is a string longer than eight chars"; ... strncpy (dest, src, sizeof(src)); /* boom */ ... The len/limit should be sizeof(dest). Note: the above example has a definite over-run. In our source the overrun is typically only theoretical (but possibly exploitable.) Also strncpy doesn't null-terminate on truncation; snprintf does; prefer snprintf over strncpy. Mildly surprising that coverity doesn't warn/isn't warning about this.
