Reference information

The mvfsstat and mvfscache utilities are intended primarily to help IBM Software Support for Rational products diagnose problems with the MVFS. No locks or mastership restrictions apply for either of these utilities, but certain options require privileged user status.

mvfscache
mvfscache manipulates a host’s MVFS caches. Nearly all of its options are redundant with similar options provided by setcache –mvfs or getcache –mvfs. Use those commands whenever possible.
mvfsstat
The mvfsstat command displays MVFS use and operating statistics, including cumulative statistics on MVFS cache use, RPC statistics, cleartext I/O counts, vnode operation counts, and VFS operation counts. This data is useful for evaluating file system performance and determining whether MVFS cache sizes require adjustment.
