Hi, I do have a centos 6.x server which accessed two different iscsistorages for a long time without any trouble. The storage-connection is done by a separate NIC and VLAN. The LAN access is on an other NIC. This weekend something broke and I don't have any clue what might be the problem or what caused it. The storages where mounted RO. In /var/loge/messages there are lot of messages; so from dmesg: Dec 10 17:13:21 richter kernel: connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324582419, last ping 4324587419, now 4324592419 Dec 10 17:13:21 richter kernel: connection3:0: detected conn error (1011) Dec 10 17:13:22 richter iscsid: Kernel reported iSCSI connection 3:0 error (1011 - ISCSI_ERR_CONN_FAILED: iSCSI connection failed) state (3) From dmesg: connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324597423, last ping 4324602423, now 4324607423 connection1:0: detected conn error (1011) I restarted the server and the filesystems are back online RW, but there are still that messages. Thanks for any suggestion or hint! Regards . Götz -- Götz Reinicke - IT-Koordinator - Filmakademie Baden-Württemberg GmbH
