Number of client filesystem I/O requests blocked because no fsbuf was available. NFS (Network File System) and VxFS (Veritas) are client filesystems. Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.

external pager filesystem I/Os blocked with no fsbuf

Number of external pager client filesystem I/O requests blocked because no fsbuf was available. JFS2 is an external pager client filesystem. Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.

Virtualized Partition Memory Page Faults

Total number of virtual partition memory page faults recorded for the virtualized partition.

Time resolving virtualized partition memory page faults

Total time (in seconds, with millisecond granularity) the virtual partition has been blocked waiting for the resolution of the virtual partition's memory page faults.

-w Display the report in wide mode.
