Re: [Openstack] [swift] RAID Performance Issue

Chuck, David, Thanks for your explanation and sharing. Since RAID 0 doesn't have parity or mirroring to provide low level redundancy which indicate there's no write penalty, it can improve overall performance for concurrent IO of multiple disks. I'm wondering if it make sense to use such kind of R

There are a couple of things to think about when using RAID (or more specifically parity RAID) with swift. The first has already been identified in that the workload for swift is very write heavy with small random IO, which is very bad for most parity RAID. In our testing, under heavy workloads,

Re: [Openstack] Instances can't reach metadata server in network HA mode

Are you sure your network has multi_host = True? It seems like it isn't, since the gateway listed by the guest is 10.5.5.32 In multi_host mode each node should be getting an ip from the fixed range and the guest should be using that as the gateway. Vish > > > > On Wed, Dec 19, 2012 at 1:13

There should be a redirect in iptables from 169.254.169.254:80 to $my_ip:8775 (where nova-api-metadata is running) So: a) can you curl $my_ip:8775 (should 404) b) if you do sudo iptables -t nat -L -n v do you see the forward rule? Is it getting hit properly? Vish On Dec 19, 2012, at 6
