Hey Bernhard, I've always needed the
server.allow-insecure: on for successful migrations. Also, I've not had any issues with cache=none with my machines. A copy of a disk segment from one of my working machines <disk type='network' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source protocol='gluster' name='VMARRAY/HFMMNG1.img'> <host name='10.9.1.2' port=''/> </source> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> Best, Josh ----- Original Message ----- From: "Bernhard Glomm" <[email protected]> To: [email protected] Cc: [email protected] Sent: Thursday, January 16, 2014 9:02:54 AM Subject: Re: [Gluster-users] gluster and kvm livemigration btw: The VM are configured to use cache=writethrough since cache=none doesn't work (can't install the machine because of i/o errors when I try to use the disk) can't start an installed machine with cache=none with cache=writethrough and cache=writeback the machines starts and runs, but lifemigration shows both time the same issue that the disk will become readonline on successful migration remount, reboot failed only a shutdown and a restart works. TIA Bernhard <blockquote> I experienced a strange behavior of glusterfs during livemigration of a qemu-kvm guest using a 10GB file on a mirrored gluster 3.4.2 volume (both on ubuntu 13.04) I run virsh migrate --verbose --live --unsafe --p2p --domain atom01 --desturi qemu+ssh://<target_ip>/system and the migration works, the running machine is pingable and keeps sending pings. nevertheless, when I let the machine touch a file during migration it stops, complaining that it's filesystem is read only (from that moment that migration finished) A reboot from inside the machine failes, machine goes down and comes up with an error unable to write to sector xxxxxx on hd0 (than falling into the initrd). a virsh destroy VM && virsh start VM leads to a perfect running VM again, no matter on which of the two hosts I start the machine anybody better experience with livemigration? any hint on a procedure how to debug that? </blockquote> _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
