| Hello list. Newbie question: I’m building a low-performance/low-cost storage service with a starting size of about 500TB, and want to use Gluster with erasure coding. I’m considering subvolumes of maybe 4+2, or 8+3 or 4. I was thinking I’d spread these over 4 nodes, and add single nodes over time, with subvolumes rearranged over new nodes to maintain protection from whole node failures. However, reading through some RedHat-provided documentation, they seem to suggest that node counts should be a multiple of 3, 6 or 12, depending on subvolume config. Is this actually a requirement, or is it only a suggestion for best performance or something? Can anyone comment on node count constraints with erasure coded subvolumes? Thanks in advance for anyone’s reply, Terry _____________________________ Terry McGuire Information Services and Technology (IST) University of Alberta Edmonton, Alberta, Canada T6G 2H1 Phone: 780-492-9422 |
