* glusterd: Fix Add-brick with increasing replica count failureSheetal Pamecha2020-09-241-0/+21
| | | | | | | | | | | | | Problem: add-brick operation fails with multiple bricks on same server error when replica count is increased. This was happening because of extra runs in a loop to compare hostnames and if bricks supplied were less than "replica" count, the bricks will get compared to itself resulting in above error. Fixes: #1508 Change-Id: I8668e964340b7bf59728bb838525d2db062197ed Signed-off-by: Sheetal Pamecha <spamecha@redhat.com>

* glusterd: getspec() returns wrong response when volfile not foundTamar Shacked2020-07-231-0/+3
| | | | | | | | | | | | | | | In a cluster env: getspec() detects that volfile not found. but further on, this return code is set by another call so the error is lost and not handled. As a result the server responds with ambiguous message: {op_ret = -1, op_errno = 0..} - which cause the client to stuck. Fix: server side: don't override the failure error. fixes: #1375 Change-Id: Id394954d4d0746570c1ee7d98969649c305c6b0d Signed-off-by: Tamar Shacked <tshacked@redhat.com>

* glusterd: add-brick command failureSanju Rakonde2020-06-211-0/+40
| | | | | | | | | | | | | | | Problem: add-brick operation is failing when replica or disperse count is not mentioned in the add-brick command. Reason: with commit a113d93 we are checking brick order while doing add-brick operation for replica and disperse volumes. If replica count or disperse count is not mentioned in the command, the dict get is failing and resulting add-brick operation failure. fixes: #1306 Change-Id: Ie957540e303bfb5f2d69015661a60d7e72557353 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* test: Test case brick-mux-validation-in-cluster.t is failing on RHEL-8Mohit Agrawal2020-06-091-3/+1
| | | | | | | | | | | | | | | | | | | | | Brick process are not properly attached on any cluster node while some volume options are changed on peer node and glusterd is down on that specific node. Solution: At the time of restart glusterd it got a friend update request from a peer node if peer node having some changes on volume.If the brick process is started before received a friend update request in that case brick_mux behavior is not workingproperly. All bricks are attached to the same process even volumes options are not the same. To avoid the issue introduce an atomic flag volpeerupdate and update the value while glusterd has received a friend update request from peer for a specific volume.If volpeerupdate flag is 1 volume is started by glusterd_import_friend_volume synctask Change-Id: I4c026f1e7807ded249153670e6967a2be8d22cb7 Credit: Sanju Rakaonde <srakonde@redhat.com> fixes: #1290 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
* io-cache,quick-read: deprecate volume options with flawed semantics or namingCsaba Henk2020-06-022-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | - performance.cache-size has a flawed semantics, as it's dispatched on two independent translators, io-cache and quick-read. - performance.qr-cache-timeout has a confusing name, as other options affecting quick-read have an unabbreviated "quick-read-..." prefix in their names. We keep these options with unchanged operation, but in the help output we indicate their deprecation. The following better alternatives are introduced: - performance.io-cache-size to tune cache-size option of io-cache - performance.quick-read-cache-size to tune cache-size option of quick-read - performance.quick-read-cache-timeout as a preferred synonym for performance.qr-cache-timeout Fixes: #952 Change-Id: Ibd04fb638de8cac450ba992ad8a415154f9f4281 Signed-off-by: Csaba Henk <csaba@redhat.com>

* glusterd: Brick process fails to come up with brickmux onVishal Pandey2020-02-201-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: 1- In a cluster of 3 Nodes N1, N2, N3. Create 3 volumes vol1, vol2, vol3 with 3 bricks (one from each node) 2- Set cluster.brick-multiplex on 3- Start all 3 volumes 4- Check if all bricks on a node are running on same port 5- Kill N1 6- Set performance.readdir-ahead for volumes vol1, vol2, vol3 7- Bring N1 up and check volume status 8- All bricks processes not running on N1. Root Cause - Since, There is a diff in volfile versions in N1 as compared to N2 and N3 therefore glusterd_import_friend_volume() is called. glusterd_import_friend_volume() copies the new_volinfo and deletes old_volinfo and then calls glusterd_start_bricks(). glusterd_start_bricks() looks for the volfiles and sends an rpc request to glusterfs_handle_attach(). Now, since the volinfo has been deleted by glusterd_delete_stale_volume() from priv->volumes list before glusterd_start_bricks() and glusterd_create_volfiles_and_notify_services() and glusterd_list_add_order is called after glusterd_start_bricks(), therefore the attach RPC req gets an empty volfile path and that causes the brick to crash. Fix- Call glusterd_list_add_order() and glusterd_create_volfiles_and_notify_services before glusterd_start_bricks() cal is made in glusterd_import_friend_volume Change-Id: Idfe0e8710f7eb77ca3ddfa1cabeb45b2987f41aa Fixes: bz#1773856 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* glusterd: deafult options after volume resetSanju Rakonde2020-01-011-0/+5
| | | | | | | | | | | | | | | | | | | Problem: default option itransport.address-family is disappered in volume info output after a volume reset. Cause: with 3.8.0 onwards volume option transport.address-family has default value, any volume which is created will have this option set. So, volume info will show this in its output. But, with reset volume, this option is not handled. Solution: In glusterd_enable_default_options(), we should add this option along with other default options. This function is called by glusterd_options_reset() with volume reset command. fixes: bz#1786478 Change-Id: I58f7aa24cf01f308c4efe6cae748cc3bc8b99b1d Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* cli: display detailed rebalance infoSanju Rakonde2019-11-121-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: When one of the node is down in cluster, rebalance status is not displaying detailed information. Cause: In glusterd_volume_rebalance_use_rsp_dict() we are aggregating rsp from all the nodes into a dictionary and sending it to cli for printing. While assigning a index to keys we are considering all the peers instead of considering only the peers which are up. Because of which, index is not reaching till 1. while parsing the rsp cli unable to find status-1 key in dictionary and going out without printing any information. Solution: The simplest fix for this without much code change is to continue to look for other keys when status-1 key is not found. fixes: bz#1764119 Change-Id: I0062839933c9706119eb85416256eade97e976dc Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* mgmt/shd: Implement multiplexing in self heal daemonMohammed Rafi KC2019-04-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Shd daemon is per node, which means they create a graph with all volumes on it. While this is a great for utilizing resources, it is so good in terms of performance and managebility. Because self-heal daemons doesn't have capability to automatically reconfigure their graphs. So each time when any configurations changes happens to the volumes(replicate/disperse), we need to restart shd to bring the changes into the graph. Because of this all on going heal for all other volumes has to be stopped in the middle, and need to restart all over again. Solution: This changes makes shd as a per volume daemon, so that the graph will be generated for each volumes. When we want to start/reconfigure shd for a volume, we first search for an existing shd running on the node, if there is none, we will start a new process. If already a daemon is running for shd, then we will simply detach a graph for a volume and reatach the updated graph for the volume. This won't touch any of the on going operations for any other volumes on the shd daemon.

* glusterd: ensure volinfo->caps is set to correct value.Sanju Rakonde2018-10-251-0/+9
| | | | | | | | | | | | | | | | | With the commit febf5ed4848, during the volume create op, we are setting volinfo->caps to 0, only if any of the bricks belong to the same node and brickinfo->vg[0] is null. Previously, we used to set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null. With this patch, we set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null. (as we do earlier without commit febf5ed4848). fixes: bz#1635820 Change-Id: I00a97415786b775fb088ac45566ad52b402f1a49 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch https://review.gluster.org/#/c/glusterfs/+/19135/ has optimised glusterd test cases by clubbing the similar test cases into a single test case. https://review.gluster.org/#/c/glusterfs/+/19135/15/tests/bugs/glusterd/bug-1293414-import-brickinfo-uuid.t test case has been deleted and added as a part of tests/bugs/glusterd/optimized-basic-testcases-in-cluster.t In the original test case, we create a volume with two bricks, each on a separate node(N1 & N2). From another node in cluster(N3), we try to detach a node which is hosting bricks. It fails. In the new test, we created volume with single brick on N1. and from another node in cluster, we tried to detach N1. we expect peer detach to fail, but peer detach was success as the node is hosting all the bricks of volume. Now, changing the new test case to cover the original test case scenario. Please refer https://bugzilla.redhat.com/show_bug.cgi?id=1642597#c1 to understand why the new test case is not failing in centos-regression. fixes: bz#1642597 Change-Id: Ifda12b5677143095f263fbb97a6808573f513234 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* core: glusterfsd keeping fd open in index xlatorMohit Agrawal2018-10-121-0/+78
| | | | | | | | | | | | | | | | | | | | | | Problem: At the time of processing GF_EVENT_PARENT_DOWN at brick xlator, it forwards the event to next xlator only while xlator ensures no stub is in progress. At io-thread xlator it decreases stub_cnt before the process a stub and notify EVENT to next xlator Solution: Introduce a new counter to save stub_cnt and decrease the counter after process the stub completely at io-thread xlator. To avoid brick crash at the time of call xlator_mem_cleanup move only brick xlator if detach brick name has found in the graph Note: Thanks to pranith for sharing a simple reproducer to reproduce the same fixes bz#1637934 Change-Id: I1a694a001f7a5417e8771e3adf92c518969b6baa Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
* tests: fix test case failureSanju Rakonde2018-09-201-1/+1
| | | | | | | | | | | | | | | | tests/bugs/glusterd/bug-1595320.t is failing in downstream. In downstream repo, enabling the brick multiplexing made interactive, so it will throw an prompt for the user input. As no input is provided during the test case execution, the test is failing. Using macro CLI instead of using gluster command, will bypass the interacive commands. so replacing the gluster command with CLI macro will address the issue.

* tests: Fix cleanup routine for some mux testsShyamsundarR2018-08-131-3/+2
| | | | | | | | | | | | | | | | | Some of the mux tests, set a trap to catch test exit and call cleanup. This will cause cleanup to be invoked twice in case the test times out, or even otherwise, as include.rc also sets a trap to cleanup on exit (TERM and others). This leads to the tarballs generated on failures for these tests to be empty and does not aid debugging. This patch corrects this pattern across the tests to the more standard cleanup at the end.

* glusterd: Bricks of a normal volumes should not attach to ↵Sanju Rakonde2018-08-032-33/+51
| | | | | | | | | | | | | | | | | | | gluster_shared_storage bricks Problem: In a brick multiplexing environment, Bricks of a normal volume created by user are getting attached to the bricks of a volume "gluster_shared_storage" which is created by enabling the enable-shared-storage option. Mounting gluster_shared_storage has strict authentication checks. when we attach bricks of a normal volume to bricks of gluster_shared_storage, mounting the normal volume created by user will fail due to strict authentication checks. Solution: We should not attach bricks of a normal volume to brick process of gluster_shared_storage volume and vice versa. fixes: bz#1610726 Change-Id: If1b5a2a02675789a2915ba480fb48c145449163d Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* glusterd: handling brick termination in brick-muxSanju Rakonde2018-05-071-0/+33
| | | | | | | | | | | | | | | | | Problem: There's a race between the glusterfs_handle_terminate() response sent to glusterd from last brick of the process and the socket disconnect event that encounters after the brick process got killed. Solution: When it is a last brick for the brick process, instead of sending GLUSTERD_BRICK_TERMINATE to brick process, glusterd will kill the process (same as we do it in case of non brick multiplecing).
