=head1 VERSION
Version 0.01
=head1 SYNOPSIS
IBM::StorageSystem::FileSystem::FileSet - Utility class for operations with a IBM storage system filesystem filesets
use IBM::StorageSystem;
my $ibm = IBM::StorageSystem->new(
user => 'admin',
host => 'my-v7000',
key_path => '/path/to/my/.ssh/private_key'
) or die "Couldn't create object! $!\n";
=head3 alloc_inodes
Returns the number of allocated inodes for the fileset.
B<Note> that the number of allocated inodes is returned in a human-readable format with a variable units -
e.g. the value may be returned as 10K or 10M, where K and M refer to the unit.
=head3 comment
Returns the user-specified fileset comment.
=head3 creation_time
Returns the fileset creation time.
=head3 data
Returns the amount of data in use for the fileset in a human-readable format (kB, MB, GB, TB or PB where
1 kB is equal to 1000 bytes).
=head3 device_name
Returns the name of the file system to which the fileset belongs.
=head3 id
Returns the fileset numerical identifier.
=head3 inode_space_owner
Returns the numerical identifier of the fileset owner.
=head3 inodes
Returns the number of inodes in use.
=head3 is_independent
Specifies if the fileset is independent.
=head3 max_inodes
Returns the maximum number of allocatable inodes.
=head3 name
Returns the fileset name.
=head3 parent_id
Returns the parent fileset identifier.
=head3 path
Returns the fileset path if the fileset B<status> is linked and blank otherwise.
=head3 root_inode
Returns the number of the root inode.
=head3 get_snapshots
Returns an array of L<IBM::StorageSystem::Snapshots> for the fileset.
See L<IBM::StorageSystem::Snapshots> for more information.
=head3 status
Returns the fileset status; either linked or unlinked.
=head3 timestamp
Returns a timestamp of the last time at which the fileset information was updated in the CTDB.
