Brick count limit in a volume
Hi, Gluster version is 3.10.5. I am trying to create a 5500 brick volume, but getting an error stating that 4444 bricks is the limit. Is this a known limit? Can I change this with an option? Thanks, Serkan

Brick count limit in a volume
An upstream bug would be ideal as github issue is mainly used for enhancements. In the mean time, could you point to the exact failure shown at the command line and the log entry from cli.log?

Brick count limit in a volume
Hi, I think this is the line limiting brick count: https://github.com/gluster/glusterfs/blob/c136024613c697fec87aaff3a070862b92c57977/cli/src/cli-cmd-parser.c#L84 Can gluster-devs increase this limit?
