vhostmd – A metrics gathering daemon. Synopsis vhostmd [ OPTION ] Description vhostmd provides a "metrics communication channel" between a host and its hosted virtual machines, allowing limited introspection of host resource usage from within virtual machines. This functionality may be useful in hosting environments, giving virtual machine administrators a limited view of host resource…
vgsplit – Move physical volumes into a new or existing volume group Synopsis vgsplit option_args position_args [ option_args ] Description vgsplit moves one or more PVs from a source VG to a destination VG. The PVs can be specified explicitly or implicitly by naming an LV, in which case on PVs underlying the LV are moved. If…
vgscan – Search for all volume groups Synopsis vgscan [ option_args ] Description vgscan scans all supported LVM block devices in the system for VGs. Usage vgscan [ –ignorelockingfailure ] [ –mknodes ] [ –notifydbus ] [ –reportformat basic|json ] [ COMMON_OPTIONS ] Common options for lvm: [ -d|–debug ] [ -h|–help ] [ -q|–quiet ] […
