Modify traces retention settings

Command: weka debug traces retention set [--server-max server-max] [--client-max client-max] [--server-ensure-free server-ensure-free] [--client-ensure-free client-ensure-free]

Parameters

Parameter	Description	Default
server-max	Maximum capacity to retain per server.	50GB per IO-node with a minimum of 100GB
client-max	Maximum capacity to retain per client.	50GB per IO-node with a minimum of 100GB
server-ensure-free	Always maintain at least this much capacity to remain free on servers.	50GB per IO-node with a minimum of 100GB
client-ensure-free	Always maintain at least this much capacity to remain free on clients.	50GB per IO-node with a minimum of 100GB

To modify the trace retention setting of a single client, you can use the traces_capacity_mb mount command. See Additional mount options using the stateless clients feature.
