@v = $ec2->describe_volumes(-volume_id=>\@ids,-filter=>\%filters)

@v = $ec2->describe_volumes(@volume_ids)

 -volume_id    The id of the volume to fetch, either a string
               scalar or an arrayref.

 -filter       One or more filters to apply to the search

The -filter argument name can be omitted if there are no other arguments you wish to pass.

The full list of volume filters can be found at: http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeVolumes.html

$v = $ec2->create_volume(-availability_zone=>$zone,-snapshot_id=>$snapshotId,-size=>$size,-volume_type=>$type,-iops=>$iops,-encrypted=>$boolean)

Arguments:

 -availability_zone    -- An availability zone from
                          describe_availability_zones (required)

 -snapshot_id          -- ID of a snapshot to use to build volume from.

 -size                 -- Size of the volume, in GB (between 1 and 1024).

One or both of -snapshot_id or -size are required. For convenience, you may abbreviate -availability_zone as -zone, and -snapshot_id as -snapshot.

Optional Arguments:

 -volume_type          -- The volume type.  "standard", "io1", or "gp2"
                          Default is "standard"

 -iops                 -- The number of I/O operations per second (IOPS) that
                          the volume supports.  Range is 100 to 4000.  Required
                          when volume type is io1.  IOPS must be 30-to-1 ratio
                          to size.  ie: 3000 IOPS volume must be at least 100GB.

 -encrypted            -- Specifies whether the volume should be encrypted.
                          Encrypted Amazon EBS volumes may only be attached to
                          instances that support them. Volumes created from
                          encrypted snapshots are also encrypted using the same
                          key as the original volume.
                          See: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html

The returned object is a VM::EC2::Volume object.

$result = $ec2->delete_volume($volume_id);

$attachment = $ec2->attach_volume($volume_id,$instance_id,$device);

$attachment = $ec2->attach_volume(-volume_id=>$volume_id,-instance_id=>$instance_id,-device=>$device);

 -volume_id      -- ID of the volume to attach. The volume must be in
                    "available" state.
 -instance_id    -- ID of the instance to attach to. Both instance and
                    attachment must be in the same availability zone.
 -device         -- How the device is exposed to the instance, e.g.
                    '/dev/sdg'.

The result is a VM::EC2::BlockDevice::Attachment object which you can monitor by calling current_status():

    my $a = $ec2->attach_volume('vol-12345','i-12345','/dev/sdg');
    while ($a->current_status ne 'attached') {
       sleep 2;
    }
    print "volume is ready to go\n";

or more simply

    my $a = $ec2->attach_volume('vol-12345','i-12345','/dev/sdg');
    $ec2->wait_for_attachments($a);

$attachment = $ec2->detach_volume($volume_id)

$attachment = $ec2->detach_volume(-volume_id=>$volume_id,-instance_id=>$instance_id, -device=>$device, -force=>$force);

 -volume_id      -- ID of the volume to detach. (required)
 -instance_id    -- ID of the instance to detach from. (optional)
 -device         -- How the device is exposed to the instance. (optional)
 -force          -- Force detachment, even if previous attempts were
                    unsuccessful. (optional)

The result is a VM::EC2::BlockDevice::Attachment object which you can monitor by calling current_status():

    my $a = $ec2->detach_volume('vol-12345');
    while ($a->current_status ne 'detached') {
       sleep 2;
    }
    print "volume is ready to go\n";

Or more simply:

    my $a = $ec2->detach_volume('vol-12345');
    $ec2->wait_for_attachments($a);
    print "volume is ready to go\n" if $a->current_status eq 'detached';

$ec2->wait_for_attachments(@attachment)

Typical usage:

    my $i = 0;
    my $instance = 'i-12345';
    my @attach;
    foreach (@volume) {
        push @attach,$_->attach($instance,'/dev/sdf'.$i++;
    }
    my $s = $ec2->wait_for_attachments(@attach);
    my @failed = grep($s->{$_} ne 'attached'} @attach;
    warn "did not attach: ",join ', ',@failed;

If no terminal state is reached within a set timeout, then this method returns undef and sets $ec2->error_str() to a suitable message. The timeout, which defaults to 10 minutes (600 seconds), can be get or set with $ec2->wait_for_timeout().

@v = $ec2->describe_volume_status(@volume_ids)

@v = $ec2->describe_volume_status(\%filters)

@v = $ec2->describe_volume_status(-volume_id=>\@ids,-filter=>\%filters)

 -volume_id    The id of the volume to fetch, either a string
               scalar or an arrayref.

 -filter       One or more filters to apply to the search

 -max_results  Maximum number of items to return (must be more than
                5).

The -filter argument name can be omitted if there are no other arguments you wish to pass.

The full list of volume filters can be found at: http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeVolumeStatus.html

If -max_results is specified, then the call will return at most the number of volume status items you requested. You may see whether there are additional results by calling more_volume_status(), and then retrieve the next set of results with additional call(s) to describe_volume_status():

 my @results = $ec2->describe_volume_status(-max_results => 10);
 do_something(\@results);
 while ($ec2->more_volume_status) {
    @results = $ec2->describe_volume_status;
    do_something(\@results);
 }

$ec2->wait_for_volumes(@volumes)

If no terminal state is reached within a set timeout, then this method returns undef and sets $ec2->error_str() to a suitable message. The timeout, which defaults to 10 minutes (600 seconds), can be get or set with $ec2->wait_for_timeout().

@data = $ec2->describe_volume_attribute($volume_id,$attribute)

 autoEnableIO                      -- boolean
 productCodes                      -- list of scalar

These values can be retrieved more conveniently from the VM::EC2::Volume object returned from describe_volumes():

 $volume->auto_enable_io(1);
 @codes = $volume->product_codes;

$boolean = $ec2->enable_volume_io($volume_id)

$boolean = $ec2->enable_volume_io(-volume_id=>$volume_id)

@snaps = $ec2->describe_snapshots(@snapshot_ids)

@snaps = $ec2->describe_snapshots(-snapshot_id=>\@ids,%other_args)

 -snapshot_id     ID of the snapshot

 -owner           Filter by owner ID

 -restorable_by   Filter by IDs of a user who is allowed to restore
                   the snapshot

 -filter          Tags and other filters

The -filter argument name can be omitted if there are no other arguments you wish to pass.

The full list of applicable filters can be found at http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSnapshots.html

@data = $ec2->describe_snapshot_attribute($snapshot_id,$attribute)

 createVolumePermission   -- return a list of user Ids who are
                             allowed to create volumes from this snapshot.
 productCodes             -- product codes for this snapshot

The result is a raw hash of attribute values. Please see VM::EC2::Snapshot for a more convenient way of accessing and modifying snapshot attributes.

$boolean = $ec2->modify_snapshot_attribute($snapshot_id,-$argument=>$value)

Currently the only attribute that can be changed is the createVolumeAttribute. This is done through the following arguments

 -createvol_add_user         -- scalar or arrayref of UserIds to grant create volume permissions to
 -createvol_add_group        -- scalar or arrayref of Groups to remove create volume permissions from
                               (only currently valid value is "all")
 -createvol_remove_user      -- scalar or arrayref of UserIds to remove from create volume permissions
 -createvol_remove_group     -- scalar or arrayref of Groups to remove from create volume permissions

You can abbreviate these to -add_user, -add_group, -remove_user, -remove_group, etc.

See VM::EC2::Snapshot for more convenient methods for interrogating and modifying the create volume permissions.

$boolean = $ec2->reset_snapshot_attribute($snapshot_id,$attribute)

$snapshot = $ec2->create_snapshot($volume_id)

$snapshot = $ec2->create_snapshot(-volume_id=>$vol,-description=>$desc)

Arguments:

 -volume_id    -- ID of the volume to snapshot (required)

 -description  -- A description to add to the snapshot (optional)

The return value is a VM::EC2::Snapshot object that can be queried through its current_status() interface to follow the progress of the snapshot operation.

Another way to accomplish the same thing is through the VM::EC2::Volume interface:

  my $volume = $ec2->describe_volumes(-filter=>{'tag:Name'=>'AccountingData'});
  $s = $volume->create_snapshot("Backed up at ".localtime);
  while ($s->current_status eq 'pending') {
     print "Progress: ",$s->progress,"% done\n";
  }
  print "Snapshot status: ",$s->current_status,"\n";

$boolean = $ec2->delete_snapshot($snapshot_id)

$snapshot = $ec2->copy_snapshot(-source_region=>$region,-source_snapshot_id=>$id,-description=>$desc)

$snapshot = $ec2->copy_snapshot(-region=>$region,-snapshot_id=>$id,-description=>$desc)

Required arguments:

 -source_region       -- The region the existing snapshot to copy resides in
 -source_snapshot_id  -- The snapshot ID of the snapshot to copy

 -region              -- Alias for -source_region
 -snapshot_id         -- Alias for -source_snapshot_id

Currently, the DestinationRegion and PresignedUrl API arguments are not supported. Therefore, copying encrypted snapshots between regions is not yet possible.

Optional arguments:

 -description         -- A description of the new snapshot

The return value is a VM::EC2::Snapshot object that can be queried through its current_status() interface to follow the progress of the snapshot operation.

$ec2->wait_for_snapshots(@snapshots)

This method may potentially wait forever. It has no set timeout. Wrap it in an eval{} and set alarm() if you wish to timeout.
