I/O performance
i want to determine I/O performance of an
executable,
but iostat dont give correct results because
the disk that i am writing to and reading from,
are not physical disk of the host machine,
instead of these local disks we are using
a network storage.
is there any standard way in unix to get these performance results

pvremove
pvremove(1M) pvremove(1M)
NAME
pvremove - remove LVM data structure from a physical volume
SYNOPSIS
DESCRIPTION
The command clears the LVM data structure on a disk, so that it is no longer an LVM physical volume. The device may then be used by the
file system or by other volume managers.
The operation is denied if pv_path is assigned to a volume group. The command only clears the LVM data structure on a disk if the disk
does not belong to a volume group. This avoids accidentally removing a valid physical volume under a volume group. If the physical volume
to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.
Arguments
recognizes the following arguments:
pv_path The character (raw) device path name of a physical volume.
EXTERNAL INFLUENCES
Environment Variables
determines the language in which messages are displayed.
If is not specified or is null, it defaults to "C" (see lang(5)).
If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).
EXAMPLES
Remove LVM data structure on the physical volume
