[Xen-users] xen + drbd - live migration fails when rebooting domU
Hello, Please CC me as I am not subscribed. I''m testing xen + drbd cluster to use live migration. I have 2 machines with Debian Squeeze 2.6.32-5-xen-amd64 xen 4.0.1-2, drbd 8.3.7 DomU is located on lvm volume(size 5GB) and is replicated with drbd. Debian Squeeze amd64 without swap file. Live migration works ok but there is one issue: First reboot vm: domU1:# reboot then try to migrate: ha1:#xm migrate domU1 ha2 --live strace -p `pidof xc_save` show lots of this: write(2, "type fail: page 1020 mfn 000a2f7"..., 34) = 34 write(2, "type fail: page 1021 mfn 000a2f7"..., 34) = 34 write(2, "type fail: page 1022 mfn 000a2f7"..., 34) = 34 write(2, "type fail: page 1023 mfn 000a2f7"..., 34) = 34 write(5, "\0\4\0\0", 4) = 4 write(5, "\0\0\0\360\0\0\0\0\0\0\0\360\0\0\0\0\0\0\0\360\0\0\0\0\0\0\0\360\0\0\0\0"..., 8192) = 8192 munmap(0x7f68159ee000, 4194304) = 0 ioctl(3, SNDCTL_DSP_RESET, 0x7fff2870f0e0) = 0 mmap(NULL, 4194304, PROT_READ, MAP_SHARED, 3, 0) = 0x7f68159ee000 ioctl(3, SNDCTL_DSP_GETBLKSIZE, 0x7fff2870f0d0) = -1 EINVAL (Invalid argument) ioctl(3, SNDCTL_DSP_STEREO, 0x7fff2870f0f0) = 0 ioctl(3, SNDCTL_DSP_RESET, 0x7fff2870f0f0) = 0 write(2, "type fail: page 0 mfn 000a2f79\n", 31) = 31 write(2, "type fail: page 1 mfn 000a2f78\n", 31) = 31 write(2, "type fail: page 2 mfn 000a2f77\n", 31) = 31 In the end migration fails with: Error: timed out If "xm migrate domU1 ha2 --live" command is issued first and the vm is rebooted, live migration works as expected. Am I missing something obvious or is it a bug ? Regards, _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
