Glad I could help, Uwe. We do use hardware RAID inside the servers. The reason being is because gluster isn't block level so doing a remirror/resync with 80+ million files takes weeks - so if we lose a hard drive the rebuild time would be unacceptable. With hardware raid a rebuild takes only a day or two. We access our clusters mostly via the native fuse gluster client because performance via the NFS client is somewhat slow. However we do have a few clients that connect via NFS so we can mount readonly or that don't require a lot of performance. liam On Thu, Aug 4, 2011 at 11:13 AM, Uwe Kastens <kisteorg at googlemail.com> wrote: > Hello Liam, > > Thank you for sharing information.
