Public bug reported: Binary package hint: open-iscsi
Hi, I installed iscsitarget on my host, and in a kvm guest, I tried to use my configured target. First my setup: Host: Intrepid, latest proposed linux image (with fixes for iscsitarget) cat /etc/ietd.conf | grep -ve ^.*# -ve ^$ Target iqn.2008-12.de.roessner-net:storage.disk0.testing Lun 0 Path=/dev/vg01/lv_testing,Type=fileio Alias Test HeaderDigest CRC32C,None DataDigest CRC32C,None The host is still running fine, with following dmesg-output, after the guest has been died: ... [ 2220.173286] vcpu not ready for apic_round_robin [ 2220.670873] vcpu not ready for apic_round_robin [ 2220.673095] vcpu not ready for apic_round_robin [ 2221.171379] vcpu not ready for apic_round_robin [ 2221.173452] vcpu not ready for apic_round_robin [ 2278.588125] vcpu not ready for apic_round_robin ... Does not wonder me, because the guest is dead :-) The guest: Jaunty (Former Intrepid with same results): Here the commands, I set in the guest, directly copied over from the dead console: ubuntu /etc/rcS.d # mv S25open-iscsi S45open-iscsi ubuntu /etc/rcS.d # vi S45open-iscsi ubuntu /etc/rcS.d # cd ubuntu ~ # cd /etc/iscsi/ ubuntu /etc/iscsi # vi iscsid.conf ubuntu /etc/iscsi # iscsiadm -m discovery -tst -p 10.253.1.254 -d3 iscsiadm: Max file limits 1024 1024 iscsiadm: starting sendtargets discovery, address 10.253.1.254:3260, iscsiadm: connecting to 10.253.1.254:3260 iscsiadm: connected local port 53014 to 10.253.1.254:3260 iscsiadm: connected to discovery address 10.253.1.254 iscsiadm: login response status 0000 iscsiadm: discovery process to 10.253.1.254:3260 exiting iscsiadm: Could not open /etc/iscsi/send_targets/10.253.1.254,3260 err 2 10.253.1.254:3260,1 iqn.2008-12.de.roessner-net:storage.disk0.testing ubuntu /etc/iscsi # iscsiadm -m node -T iqn.2008-12.de.roessner-net:storage.disk0.testing -p 10.253.1.254 -l Logging in to [iface: default, target: iqn.2008-12.de.roessner-net:storage.disk0.testing, portal: 10.253.1.254,3260] Login to [iface: default, target: iqn.2008-12.de.roessner-net:storage.disk0.testing, portal: 10.253.1.254,3260]: successful ubuntu /etc/iscsi # Crash I only changed two things in the config file. I set manual to automatic mount and enabled CRC32 stuff for header and data. I first had tested this setup on my development server with 4 guests using one target with ocfs2. On the intrepid nodes, I could mount the partition and start bonnie++. But after a while, all nodes died. So this time I tried to set up a little testing scenario here at my home desktop, to fill this bug and as you can see, it also crashes.
