After deleting io-threads from the vols, quota operates (list/set/modify) lets glusterfsd crash. I use it at CentOS 7 (CentOS Linux release 7.3.1611) with glusterfs 3.8.12. It seems the stack corrupt, when testing with the following diff, glusterfsd runs correctly. There are two questions as, 1. When using valgrind, it shows there are many "Invalid read/write" when with io-threads. Why glusterfsd runs correctly with io-threads? but crash without io-threads? 2. With the following diff, valgrind also shows many "Invalid read/write" when without io-threads? but no any crash. Any comments are welcome. Revert http://review.gluster.org/11499 seems better than the diff. diff --git a/xlators/features/marker/src/marker-quota.c b/xlators/features/marke index 902b8e5..f3d2507 100644 --- a/xlators/features/marker/src/marker-quota.c +++ b/xlators/features/marker/src/marker-quota.c @@ -1075,7 +1075,7 @@ mq_synctask1 (xlator_t *this, synctask_fn_t task, gf_boole } if (spawn) { - ret = synctask_new1 (this->ctx->env, 1024 * 16, task, + ret = synctask_new1 (this->ctx->env, 0, task, mq_synctask_cleanup, NULL, args); if (ret) { gf_log (this->name, GF_LOG_ERROR, "Failed to spawn " -----------------------------------test steps ---------------------------------- 1. gluster volume create gvtest node1:/test/ node2:/test/ 2. gluster volume start gvtest 3. gluster volume quota enable gvtest 4.
