Hi! Thanks for the answer. Below is the kernel message I am repeatly getting in the log. The system crash only with the interaction between xen, iscsi and multipath. Again, system is Debian Squeeze running on a Fujitsu PRIMERGY RX200 S4 with 8 cores Intel(R) Xeon(R) CPU E5405 @ 2.00GHz iSCSI is from a EMC cabinet. Any help, please?

I want to update my Debian Lenny xen servers to Squeeze. I am testing with a new install. All installs Ok but when I install the multipath package I get a kernel crash. I am searched a bit with google but I have not found any solution. Are there anybody in the list working with this configuration? PS: If I boot my server without Xen, with a standard kernel, multipath and the other is working right.What exactly crashes? dom0 ? Do you get a kernel dump on the console? I have pretty much the same setup here (iSCSI + multipath + Xen + Squeeze dom0 + Lenny/Etch PVM domUs) and I had some trouble with multipath and iSCSI beeing a little touchy. Basically my dom0 kernel hates to have fast iSCSI logout/login sequences. You'll have to give multipathd some time to cleanly remove multipath devices before you do another login. Otherwise I get stuff like this where kpartx (the thing that manages of device nodes for partitions) triggers some race condition: Feb 10 06:46:43 xenhost03 kernel: [225060.039126] BUG: unable to handle kernel paging request at ffff88001558b010 Feb 10 06:46:43 xenhost03 kernel: [225060.039172] IP: [<ffffffff8100e428>] xen_set_pmd+0x15/0x2c Feb 10 06:46:43 xenhost03 kernel: [225060.039210] PGD 1002067 PUD 1006067 PMD 18a067 PTE 801000001558b065 Feb 10 06:46:43 xenhost03 kernel: [225060.039253] Oops: 0003 [#1] SMP Feb 10 06:46:43 xenhost03 kernel: [225060.039284] last sysfs file: /sys/devices/virtual/block/dm-6/dm/suspended Feb 10 06:46:43 xenhost03 kernel: [225060.039319] CPU 0 Feb 10 06:46:43 xenhost03 kernel: [225060.039344] Modules linked in: tun dm_round_robin crc32c xt_tcpudp nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack xt_physdev iptable_filter ip_tables x_tables bridge stp xen_evtchn xenfs ib_iser rdma_cm ib_c m iw_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi dm_multipath scsi_dh loop snd_hda_intel snd_hda_codec snd_hwdep snd_pcm i915 drm_kms_helper drm snd_timer i2c_i801 evdev parport_pc psmouse serio_raw pcspkr i2c_ algo_bit parport i2c_core snd soundcore video output snd_page_alloc button processor acpi_processor ext3 jbd mbcache dm_mod sd_mod crc_t10dif usbhid hid uhci_hcd ata_generic ata_piix libata ehci_hcd scsi_mod e1000e usbcore nls_base thermal thermal_sys [last unloaded: scsi_wait_scan] Feb 10 06:46:43 xenhost03 kernel: [225060.039851] Pid: 9259, comm: kpartx_id Not tainted 2.6.32-5-xen-amd64 #1 To Be Filled By O.E.M.

Those only disapeared when I gave my dom0 a fixed ammount of RAM instead of balooning it down. Other than that I had no bad trouble. (Well, life migration of Lenny 32 bit domUs on 64bit dom0 doesn't work because the Lenny domU kernel is not good at that). I didn't do a new install of squeeze though. I started with lenny and upgraded to squeeze. cheers -henrik _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
