Red Hat Summit17장. Enabling faster client IO or recovery IO during OSD backfill
During a maintenance window, you may want to favor either client IO or recovery IO. Favoring recovery IO over client IO will significantly reduce OSD recovery time. The valid recovery profile options are balanced, high_client_ops, and high_recovery_ops. Set the recovery profile using the following procedure.
Prerequisites
- Download the OpenShift Data Foundation command line interface (CLI) tool. With the Data Foundation CLI tool, you can effectively manage and troubleshoot your Data Foundation environment from a terminal. You can find a compatible version and download the CLI tool from the customer portal.
Procedure
Check the current recovery profile:
$ odf get recovery-profileModify the recovery profile:
$ odf set recovery-profile <option>Replace
optionwith eitherbalanced,high_client_ops, orhigh_recovery_ops.Verify the updated recovery profile:
$ odf get recovery-profile
