Is /ceph/blastdb a directory? Which > version of ceph are you using? OK, let's backtrack a little. I've a 32GB (at the last count) haystack. It is split into >=2GB files b/c of the limit in our "needle search" application. I want all of that to be local on each host running the application. So from what you're saying I have to set_layout on every file individually, I can't set it on the haystack directory because it's too big. Correct? The haystack is being generated before the run, I don't know how many files there are. So if I understand it correctly, - I create the files, - set_layout for each, - wait for them to get copied to every host (osd)? Ceph is bobtail from rpms, the kernel is more of a problem as it's a stock elrepo's build of 3.0 (.65 ATM). -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
