which cpu?
Which cpu is hit when domU does the heavy disk IO? dom0 cpu or domU cpu? I can see tapdisk in dom0 eating CPU. I have (dom0-cpus 1) setup in xen config. Thanks!

relocation, migration
Hi, I am running a cluster having 2 nodes using red hat cluster suite. node 1 has a para virtualized guest(centOS) running under Xen. My question is when node1 is rebooted, guest is automatically relocated to node 2 . Instead of relocation, is migration possible in this case which can result in Zero down time? Thanks in adv Paras. -------------- next part -------------- An HTML attachment was

data recovery
Hi, Need help on data recovery. Suddenly my disk device's geometry has been changed to something that doesnot make any sense. Its a 1.8TB in size and had only one single partition. Now I can see 3 partitions sde1, sde2 and sde2 of sizes 130M, 140GB and 10GB. Is there any way to recover data from these newly created disk devices? Thanks Paras.

gnbd and xen
hi all.. Is it recommended to use GNBD in production cluster? . The main purpose of this cluster would be to provide high availablity of Xen virtual machines. I don''t have a fencing device hence I am giving a thought to use GNBD since it can be used in fencing without any fencing hardware. Also, any pointers to the tutorial on using gnbd with RHCS and xen would be great. Thanks Paras.

lvm uuid
Hi, I added additional storage to my domU using xm block-attach and tap:aio. Then increased my root device (using vgextend, lvextend and resizefs) which is / or /dev/mapper/VolGroup00-LogVol00. Everything worked fine util I did "xm save domid test1.img" This stopped my domU. And now when I run: xm create domU -c , I am seeing -- Scanning logical volumes Reading all physical volumes.
