Red Hat Bugzilla – Bug 819698
Stop fcoe-target daemon cannot remove all fcoe-target session.
Last modified: 2013-02-21 05:48:42 EST
Description of problem: After fcoe-target daemon stop, all fcoe-target session is still running. /etc/init.d/fcoe-taget ==== 112 stop() 113 { 114 echo "Stopping $prog: " 115 116 echo -n " Unloading $prog modules... " 117 stop_ccsd 118 if [ $? -eq 0 ] 119 then 120 >---echo "done" 121 else 122 >---echo "failed" 123 >---return 1 124 ==== stop_ccsd() didn't exist. You must mean "unload_modules()" function. Version-Release number of selected component (if applicable): fcoe-target-utils-2.0rc1.fb10-4.el6.noarch How reproducible: 100% Steps to Reproduce: 1. Start FCoE target session. 2. Stop fcoe-target daemon. 3. Check wether fcoe-taget session got removed. Actual results: all target session still exist. Expected results: all target session got removed. Additional info: No sure whether change "stop_ccsd()" to "unload_modules()" fix the problem or not. Please be informed, this bug is aim to make sure all fcoe-target session got disabled when daemon stop. BTW: 1. the format of /etc/target/saveconfig.json is not user-friently. 2. the way of targetcli force us to use "expect" or similar tool for scripting. 3. scsi-target-utils set a very good example for how a target severs should be.
please ignore the BTW_2, I notice targetcli support non-interactive mode.

Reopen, Stop daemon still failed like these: ===== [root@storageqe-14 ~]# /etc/init.d/fcoe-target stop Deactivating FCoE Target... done Unloading FCoE Target modules... failed ERROR: Module target_core_mod is in use by tcm_fc [FAILED] ===== [root@storageqe-14 ~]# lsmod|grep fc tcm_fc 27313 1 libfc 108727 1 tcm_fc target_core_mod 343420 2 tcm_fc scsi_transport_fc 55235 2 libfc,bfa scsi_tgt 12173 1 scsi_transport_fc ===== If I stop daemon again, I got this: ===== [root@storageqe-14 ~]# /etc/init.d/fcoe-target stop Deactivating FCoE Target... done Unloading FCoE Target modules... failed ERROR: Module target_core_pscsi does not exist in /proc/modules [FAILED] ===== Please use "modporbe -qra foo_a foo_b" instead of rmmod. Decrease priority and request fix in RHEL 6.4 as QE resource limit. If we found any other urgent bug for fcoe-target, we can treat this bug as exception.
VERIFY. fcoe-target-utils-2.0rc1.fb16-3.el6.noarch clear all fcoe-target on daemon stop.
