[Gluster-devel] Linux MD RAID 10 style for gluster volume

2014-01-09 Thread Sharuzzaman Ahmat Raslan
Hi all, I personally believe that the replicated-distributed requirement to have at least 2 node during expansion, is not really practical. It is not practical for low budget user, where might be only able to buy one machine at time, or add one hard disk at a time. It is also not practical for h

Hi Chris, I'm glad someone other than me asked this question :) I think there are two things at play here. 1) when btrfs is adopted then we inherited block level checksuming from the filesystem scrub. Since this operates below the file level this type of bit rot detection will be workload a

Is an optimization possible for Btrfs that avoids GlusterFS level checksums entirely? Even with data raid0, by default it writes metadata with raid1, and can determine file corruption. Such corruptions are reported by pathtofile by Btrfs. If that can be communicated to glusterfs, glusterfs could
