* protocol/client: propagte GF_EVENT_CHILD_PING only for connections to brickRaghavendra G2019-08-091-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | Two reasons: * ping responses from glusterd may not be relevant for Halo replication. Instead, it might be interested in only knowing whether the brick itself is responsive. * When a brick is killed, propagating GF_EVENT_CHILD_PING of ping response from glusterd results in GF_EVENT_DISCONNECT spuriously propagated to parent xlators. These DISCONNECT events are from the connections client establishes with glusterd as part of its reconnect logic. Without GF_EVENT_CHILD_PING, the last event propagated to parent xlators would be the first DISCONNECT event from brick and hence subsequent DISCONNECTS to glusterd are not propagated as protocol/client prevents same event being propagated to parent xlators consecutively. propagating GF_EVENT_CHILD_PING for ping responses from glusterd would change the last_sent_event to GF_EVENT_CHILD_PING and hence protocol/client cannot prevent subsequent DISCONNECT events Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Fixes: bz#1739334 Change-Id: I50276680c52f05ca9e12149a3094923622d6eaef (cherry picked from commit 5d66eafec581fb3209af74595784be8854ca40a4)
* gfapi: Fix deadlock while processing upcallSoumya Koduri2019-08-021-33/+131
| | | | | | | | | | | | | | | | | | | As mentioned in bug1733166, there could be potential deadlock while processing upcalls depending on how each xlator choose to act on it. The right way of fixing such issues is to change rpc callback communication process. - https://github.com/gluster/glusterfs/issues/697 Till then, making changes in gfapi layer to avoid any I/O processing.

* cluster/ta: Notify the clients only if there are pending healskarthik-us2019-07-244-22/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In case of thin arbiter, before index healer starts crawling the indices at every heal-timeout interval, even if there is nothing to be healed it will send an upcall notification to all the clients to release any AFR_TA_DOM_NOTIFY locks that they hold. SHD will wait for the upcall to return before proceeding with the heal even though there is nothing to be healed. This will also invalidates the cached information about the bricks states on the clients which leads to extra calls on TA from clients for the next reads & writes if needed. This will impact the IO performance. Fix: - Before sending the upcall to the clients, check for any pending heals on TA without taking any locks. - If there is nothing marked bad on TA, then continue with the index crawl to heal any dirty markings present on the files due to any post-op failure. - If there is a brick marked as bad on TA, then take the AFR_TA_DOM_NOTIFY lock on TA from SHD, get the state on TA and continue with the current healing process.

* glusterd/svc: update pid of mux volumes from the shd processMohammed Rafi KC2019-07-2415-52/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a normal volume, we are updating the pid from a the process while we do a daemonization or at the end of the init if it is no-daemon mode. Along with updating the pid we also lock the file, to make sure that the process is running fine. With brick mux, we were updating the pidfile from gluterd after an attach/detach request. There are two problems with this approach. 1) We are not holding a pidlock for any file other than parent process. 2) There is a chance for possible race conditions with attach/detach. For example, shd start and a volume stop could race. Let's say we are starting an shd and it is attached to a volume. While we trying to link the pid file to the running process, this would have deleted by the thread that doing a volume stop.

* cluster/afr: Fix incorrect reporting of gfid & type mismatchkarthik-us2019-07-203-2/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problems: 1. When checking for type and gfid mismatch, if the type or gfid is unknown because of missing gfid handle and the gfid xattr it will be reported as type or gfid mismatch and the heal will not complete. 2. If the source selected during entry heal has null gfid the same will be sent to afr_lookup_and_heal_gfid(). In this function when we try to assign the gfid on the bricks where it does not exist, we are considering the same gfid and try to assign that on those bricks. This will fail in posix_gfid_set() since the gfid sent is null. Fix: If the gfid sent to afr_lookup_and_heal_gfid() is null choose a valid gfid before proceeding to assign the gfid on the bricks where it is missing. In afr_selfheal_detect_gfid_and_type_mismatch(), do not report type/gfid mismatch if the type/gfid is unknown or not set.

GD1 will be manipulated to consider replica count to be as 2 and continue creating the volume like any other replica 2 volume but since thin-arbiter volumes need ta-brick client xlator entries for each subvolume in fuse volfile, volfile generation is modified in a way to inject these entries seperately in the volfile for every subvolume. Few more additions - 1- Save the volinfo with new fields ta_bricks list and thin_arbiter_count. 2- Introduce a new option client.ta-brick-port to add remote-port to ta-brick xlator entry in fuse volfiles. The option can be set using the following CLI syntax - gluster volume set <VOLNAME> client.ta-brick-port <PORTNO.> 3- Volume Info will contain a Thin-Arbiter-path entry to distinguish from other replicate volumes.

* posix/ctime: Fix ctime upgrade issueKotresh HR2019-06-214-16/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: On a EC volume, during upgrade from the older version where ctime feature is not enabled(or not present) to the newer version where the ctime feature is available (enabled default), the self heal hangs and doesn't complete. Cause: The ctime feature has both client side code (utime) and server side code (posix). The feature is driven from client. Only if the client side sets the time in the frame, should the server side sets the time attributes in xattr. But posix setattr/fseattr was not doing that. When one of the server nodes is updated, since ctime is enabled by default, it starts setting xattr on setattr/fseattr on the updated node/brick. On a EC volume the first two updated nodes(bricks) are not a problem because there are 4 other bricks with consistent data. However once the third brick is updated, the new attribute(mdata xattr) will cause an inconsistency on metadata on 3 bricks, which prevents the file to be repaired. Fix: Don't create mdata xattr with utimes/utimensat system call. Only update if already present.

The inode md-cache timeout should not increase conf->generation. With this patch, 1, Fop only gets generation from inode md-cache or conf, does not increase it. 2. The generation is increased at upcall invalidate, estal/enoent error invalidate, reply with zeroed out stat from write-behind.

Lastly, remove the caps (which only BD was using) and the document describing the translator.

* glusterd: log error message only when rsp.op_ret is negativeSanju Rakonde2019-06-171-1/+1
| | | | | | | | | | | | | | | | Problem: commit d42221bec9 added a log message based on rsp.op_ret check. but while running subdir-mount.t, this message is seen even on successful mounts. Solution: in __server_getspec(), return value of sys_read() is assigned to ret, which will be a non-negative number in when sys_read() is success. This non-zero value is assigned to rsp.op_ret. We should log an error only when rsp.op_ret is negative. fixes: bz#1718848 Change-Id: Ieef8ba33c2c7b4a97d4aef17543f58e66fd3b341 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

Fix: The ctime should not be incremented manually. Since gluster-nfs is planning to be deprecated, this code is being removed to fix the issue.

| | | | | | | | | | | | in many cases, gluster's cli can run as non-privileged mode (like in geo-rep non-root setup). Just because logging fails in cli, lets not fail the overall process. Not much of debugging help in CLI logs anyways. Most of the debugging happens once the call reaches server (glusterd).

| | | | | | | | | | | | | | | | | | There are many include statements that are not needed. A previous more ambitious attempt failed because of *BSD plafrom (see https://review.gluster.org/#/c/glusterfs/+/21929/ ) Now trying a more conservative reduction. It does not solve all circular deps that we have, but it does reduce some of them. There is just too much to handle reasonably (dht-common.h includes dht-lock.h which includes dht-common.h ...), but it does reduce the overall number of lines of include we need to look at in the future to understand and fix the mess later one.
