=head1 NAME

pvesm - PVE Storage Manager

=head1 SYNOPSIS

=include synopsis

=head1 DESCRIPTION

=head2 Storage pools

Each storage pool is uniquely identified by its <STORAGE_ID>.

=head3 Storage content

A storage can support several content types, for example virtual disk
images, cdrom iso images, openvz templates or openvz root directories
(C<images>, C<iso>, C<vztmpl>, C<rootdir>).

=head2 Volumes

A volume is identified by the <STORAGE_ID>, followed by a storage type
dependent volume name, separated by colon. A valid <VOLUME_ID> looks like:

 local:230/example-image.raw

 local:iso/debian-501-amd64-netinst.iso

 local:vztmpl/debian-5.0-joomla_1.5.9-1_i386.tar.gz

 iscsi-storage:0.0.2.scsi-14f504e46494c4500494b5042546d2d646744372d31616d61

To get the filesystem path for a <VOLUME_ID> use:

 pvesm path <VOLUME_ID>


=head1 EXAMPLES

 # scan iscsi host for available targets
 pvesm scan iscsi <HOST[:PORT]>

 # scan nfs server for available exports
 pvesm scan nfs <HOST>

 # add storage pools
 pvesm add <STORAGE_ID> <TYPE> <OPTIONS>
 pvesm add <STORAGE_ID> dir --path <PATH>
 pvesm add <STORAGE_ID> nfs --path <PATH> --server <SERVER> --export <EXPORT>
 pvesm add <STORAGE_ID> lvm --vgname <VGNAME>
 pvesm add <STORAGE_ID> iscsi --portal <HOST[:PORT]> --target <TARGET>

 # disable storage pools
 pvesm set <STORAGE_ID> --disable 1

 # enable storage pools
 pvesm set <STORAGE_ID> --disable 0

 # change/set storage options
 pvesm set <STORAGE_ID> <OPTIONS>
 pvesm set <STORAGE_ID> --shared 1
 pvesm set local --format qcow2
 pvesm set <STORAGE_ID> --content iso

 # remove storage pools - does not delete any data
 pvesm remove <STORAGE_ID>

 # alloc volumes
 pvesm alloc <STORAGE_ID> <VMID> <name> <size> [--format <raw|qcow2>]

 # alloc 4G volume in local storage - use auto generated name
 pvesm alloc local <VMID> '' 4G

 # free volumes (warning: destroy/deletes all volume data)
 pvesm free <VOLUME_ID>

 # list storage status
 pvesm status

 # list storage contents
 pvesm list <STORAGE_ID> [--vmid <VMID>]

 # list volumes allocated by VMID
 pvesm list <STORAGE_ID> --vmid <VMID>

 # list iso images
 pvesm list <STORAGE_ID> --iso

 # list openvz templates
 pvesm list <STORAGE_ID> --vztmpl

 # show filesystem path for a volume
 pvesm path <VOLUME_ID>
