[Gluster-devel] Is it safe to lower SHARD_MIN_BLOCK_SIZE?

[Dmitry Antipov]

I'm trying to investigate a few issues found on disperse volumes with sharding
enabled (https://github.com/gluster/glusterfs/issues/1148 for example). Since
testing on huge files may be slow and consume a lot of system resources, I'm
trying to scale SHARD_MIN_BLOCK_SIZE down to very small values, say 4K, and
use 1-4M files for testing. Since this tweak doesn't break replica 3 volumes,
I expect that it should be valid for disperse volumes as well. Is that so?
