Hi, Here is a detailed overview of my setup.
Two machines(each 4G RAM and one 2TB disk) 1. Configured as proxy + storage 2. Configured as storage I followed the folsom object storage administrator guide and created ring partitions using the following commands. # swift-ring-builder account.builder 9 2 1 # swift-ring-builder container.builder 9 2 1 # swift-ring-builder object.builder 9 2 1 I added both the storage units in the same zone, copied the *.ring.gz files to each host and restarted the services. The setup seems to be working fine for small files, but while copying large files I get errors(as stated in the previous mail). Any help would be greatly appreciated. Thanks. -- Shashank Sahni On Fri, Mar 8, 2013 at 12:51 PM, Shashank Sahni <[email protected]>wrote: > Hi everyone, > > I'm running a small test setup of swift with one proxy+storage and one > storage instance. > > The setup seems to be running well for small objects.
