5.14. Adjusting Pool Volume Multipathing

The pool_mp command adjusts multipathing for running pools. Using the pool_mp command with the -m option, you can change the type of multipathing. Using the pool_mp command with the -r option, you can reintegrate failed paths.

5.14.1. Usage

Change the Type of Multipathing

pool_mp -m {none | failover | n} [PoolName]

{none | failover | n}

Specifies the type of multipathing to be used: either none, failover, or the number of kilobytes, n, used as a round-robin stripe value.

PoolName

Specifies the pool on which to adjust multipathing. If no pool names are specified, this action is attempted on all active pools.

Reintegrate Failed Paths

pool_mp -r [PoolName]

PoolName

Specifies the pool on which to attempt restoration of any failed paths. If no pool names are specified, this action is attempted on all active pools.

pool_mp -m failover pool0

This example adjusts the multipathing for pool0 to round-robin with a stripe size of 512 KB.

pool_mp -m 512 pool0

This example restores failed paths for all active pools.
