Description of problem: iscsiadm fail to discover iscsi target with error iscsiadm: can not connect to iSCSI daemon (111)! Version-Release number of selected component (if applicable): iscsi-initiator-utils-6.2.0.873-8.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.iscsiadm -m discoverydb -t st -p IP:PORT --discover Additional info: Starting iscsid: iscsiadm: can not connect to iSCSI daemon (111)! Starting iscsid: iscsiadm: can not connect to iSCSI daemon (111)! iscsiadm: Cannot perform discovery. Initiatorname required. iscsiadm: Could not perform SendTargets discovery: could not connect to iscsid
(In reply to Meni Yakove from comment #0) Is it possible that you have an iscsid process running from an older package, with a newer iscsiadm after updating the package? Could you try restarting iscsid?

Could you try > restarting iscsid? It's seems that is the issue, I updated to iscsi-initiator-utils-6.2.0.873-8.el6.x86_64 and after reboot I can run discovery. When trying to restart iscsid service I got: Not stopping iscsid: iscsi sessions still active [WARNING] so the only way is to kill all iscsid processes or reboot the host.
Not sure this is entirely not a bug. I also experience this issue. After upgrading from iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm to iscsi-initiator-utils-6.2.0.873-10.el6.x86_64.rpm you can see in a strace output we can no longer connect to the iscsid socket via a Connection refused when I run iscsiadm -m session -P 3. 20599 write(1, "Target: iqn.2010-01.com.myhostname"..., 53) = 53 20599 write(1, "\tCurrent Portal: 172.16.0.115:32"..., 37) = 37 20599 write(1, "\tPersistent Portal: 172.16.0.115"..., 40) = 40 20599 write(1, "\t\t**********\n", 13) = 13 20599 write(1, "\t\tInterface:\n", 13) = 13 20599 write(1, "\t\t**********\n", 13) = 13 20599 write(1, "\t\tIface Name: default\n", 22) = 22 20599 write(1, "\t\tIface Transport: tcp\n", 23) = 23 20599 write(1, "\t\tIface Initiatorname: iqn.2010-"..., 55) = 55 20599 write(1, "\t\tIface IPaddress: 172.16.4.41\n", 31) = 31 20599 write(1, "\t\tIface HWaddress: <empty>\n", 27) = 27 20599 write(1, "\t\tIface Netdev: <empty>\n", 24) = 24 20599 write(1, "\t\tSID: 9\n", 9) = 9 20599 socket(PF_FILE, SOCK_STREAM, 0) = 3 20599 connect(3, {sa_family=AF_FILE, path=@"ISCSIADM_ABSTRACT_NAMESPACE"}, 30) = -1 ECONNREFUSED (Connection refused) 20599 open("/etc/iscsi/iscsid.conf", O_RDONLY) = 4 20599 fstat(4, {st_mode=S_IFREG|0600, st_size=11608, ...}) = 0 20599 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f848fca4000 20599 read(4, "#\n# Open-iSCSI default configura"..., 4096) = 4096 20599 close(4) = 0 Here's the strace output of iscsiadm -m -P 3 after I upgrade from iscsi-initiator-utils-6.2.0.872-41.el6.x86_64.rpm to iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm where its able to connect just fine 23083 write(1, "Target: iqn.2010-01.com.bluehost"..., 53) = 53 23083 write(1, "\tCurrent Portal: 172.16.0.115:32"..., 37) = 37 23083 write(1, "\tPersistent Portal: 172.16.0.115"..., 40) = 40 23083 write(1, "\t\t**********\n", 13) = 13 23083 write(1, "\t\tInterface:\n", 13) = 13 23083 write(1, "\t\t**********\n", 13) = 13 23083 write(1, "\t\tIface Name: default\n", 22) = 22 23083 write(1, "\t\tIface Transport: tcp\n", 23) = 23 23083 write(1, "\t\tIface Initiatorname: iqn.2010-"..., 55) = 55 23083 write(1, "\t\tIface IPaddress: 172.16.4.41\n", 31) = 31 23083 write(1, "\t\tIface HWaddress: <empty>\n", 27) = 27 23083 write(1, "\t\tIface Netdev: <empty>\n", 24) = 24 23083 write(1, "\t\tSID: 10\n", 10) = 10 23083 socket(PF_FILE, SOCK_STREAM, 0) = 3 23083 connect(3, {sa_family=AF_FILE, path=@"ISCSIADM_ABSTRACT_NAMESPACE"}, 110) = 0 23083 write(3, "\r\0\0\0\0\0\0\0\n\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 12856) = 12856 23083 recvfrom(3, "\r\0\0\0\0\0\0\0\0\0\0\0\3\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 2464, MSG_WAITALL, NULL, NULL) = 2464 23083 close(3) = 0 23083 write(1, "\t\tiSCSI Connection State: LOGGED"..., 36) = 36 23083 stat("/sys/subsystem/iscsi_session/devices/session10", 0x7fff6dab6b80) = -1 ENOENT (No such file or directory) 23083 stat("/sys/bus/iscsi_session/devices/session10", 0x7fff6dab6b80) = -1 ENOENT (No such file or directory) 23083 stat("/sys/class/iscsi_session/session10", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0 23083 lstat("/sys/class/iscsi_session/session10/state", {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0 23083 open("/sys/class/iscsi_session/session10/state", O_RDONLY) = 3 23083 read(3, "LOGGED_IN\n", 256) = 10 23083 close(3) = 0
