Description

this happens only if the two systems give the same "caller name" in the lock request to the server. E.g, Mostly, the RHS/RHEL systems give the caller name as `hostname` or "localhost.localdomain". In the latter case, this behaviour is observed, while in a properly configured environment wherein clients send their proper hostnames as caller_name, this works fine. If in doubt, one can always put this line: diff --git a/xlators/nfs/server/src/nlm4.c b/xlators/nfs/server/src/nlm4.c index 595738b..ee1ae80 100644 --- a/xlators/nfs/server/src/nlm4.c +++ b/xlators/nfs/server/src/nlm4.c @@ -1438,6 +1438,7 @@ nlm4svc_lock_common (rpcsvc_request_t *req, int mon) nlm4_volume_started_check (nfs3, vol, ret, rpcerr); ret = nlm_add_nlmclnt (cs->args.nlm4_lockargs.alock.caller_name); + gf_log ("debuggy", GF_LOG_CRITICAL, "lock requestor: %s", cs->args.nlm4_lockargs.alock.caller_name); ret = nfs3_fh_resolve_and_resume (cs, &fh, NULL, nlm4_lock_resume); and confirm the behaviour(and the caller names sent by the clients). |
