salt mymachine lvm.pvcreate /dev/sdb1,/dev/sdb2
salt mymachine lvm.pvcreate /dev/sdb1 dataalignmentoffset=7s
salt.modules.linux_lvm.pvdisplay(pvname=u'', real=False, quiet=False)

Return information about the physical volume(s)

pvname
physical device name
real

dereference any symlinks and report the real device

New in version 2015.8.7.

quiet
if the physical volume is not present, do not show any error

CLI Examples:

salt '*' lvm.pvdisplay

CLI Examples:

salt mymachine lvm.pvremove /dev/sdb1,/dev/sdb2
salt.modules.linux_lvm.version()

Return LVM version from lvm version

CLI Example:

salt '*' lvm.version
salt.modules.linux_lvm.vgcreate(vgname, devices, **kwargs)
