Sorry, but, no.<p>If you&#x27;ve gone to the effort of getting a massive raid like that for home use, you need a backup.<p>If you don&#x27;t have a backup, stop reading, you&#x27;re an arse.<p>Run a full backup, check restoration.<p>Blast away your NAS (its ZFS, relies on free space. The fuller it gets the slower it gets (unless you have SSDs or lots of write cache)) It&#x27;s probably due and upgrade, (OS&#x2F;XFS)<p>re-arrange your array, you&#x27;re changing the way you use it, so you need to do it.<p>Restore data back over the top (with compression...)<p>as for &quot;it costs money&quot; well thats why you chose zfs, for redundancy....
