blkmapd(8)						      System Manager's Manual							blkmapd(8)

NAME

       blkmapd - pNFS block layout mapping daemon

SYNOPSIS

       blkmapd [-d] [-f]

DESCRIPTION

       The blkmapd daemon performs device discovery and mapping for the parallel NFS (pNFS) block layout client [RFC5663].

       The pNFS block layout protocol builds a complex storage hierarchy from a set of simple volumes.	These simple volumes are addressed by con-
       tent, using a signature on the volume to uniquely name each one.  The daemon locates a volume by examining each block device in the  system
       for the given signature.

       The  topology  typically  consists of a hierarchy of volumes built by striping, slicing, and concatenating the simple volumes.  The blkmapd
       daemon uses the device-mapper driver to construct logical devices that reflect the server topology, and passes these devices to the  kernel
       for use by the pNFS block layout client.

OPTIONS

       -d     Performs device discovery only then exits.

       -f     Runs blkmapd in the foreground and sends output to stderr (as opposed to syslogd)

NAME

       pvscan - scan all disks for physical volumes

SYNOPSIS

       pvscan  [-d|--debug]  [-h|--help]  [-v|--verbose]  [--version]  [--ignorelockingfailure]  [-e|--exported] [-n|--novolumegroup] [-s|--short]
       [-u|--uuid]

       pvscan [-d|--debug] [-h|--help] --cache [--major major --minor minor | DevicePath ] ...

DESCRIPTION

       pvscan scans all supported LVM block devices in the system for physical volumes.

OPTIONS

       See lvm(8) for common options.

       -e, --exported
              Only show physical volumes belonging to exported volume groups.

       -n, --novolumegroup
              Only show physical volumes not belonging to any volume group.

       -s, --short
              Short listing format.

       -u, --uuid
              Show UUIDs (Uniform Unique Identifiers) in addition to device special names.

       --cache [ --major major --minor minor | DevicePath ] ...
              Scan one or more devices and instruct the lvmetad daemon to update its cached state accordingly.  Called internally by  udev  rules.
              All devices listed explicitly are processed regardless of any device filters set in lvm.conf.
