Storage Spaces is a new way to manage disk storage in Windows 8 and Server 2012.

Nobody can afford to use storage that is unreliable.<\/p>\n<p>Look at <a href=\"http:\/\/social.technet.microsoft.com\/Forums\/en-US\/W8ITProPreRel\/thread\/a670b2ab-10e7-4e31-9b20-5baf99a40eea\/\" target=\"_blank\">this thread<\/a> though, based on Windows 8 Enterprise Evaluation which should be the RTM code:<\/p>\n<blockquote>\n<p>I had three empty discs which I used for it: 320 GB, 1 TB, 2 TB. The manager told me that the maximum capacity for this setup would be ~2 TB.  <\/p>\n<p>I then proceeded to fill the space up, resulting in a horrible write speed of ~20 MB\/sec. Okay, that can be accepted, it is a software solution, after all.  <\/p>\n<p>Here&#8217;s the kicker, though: Upon reaching ~0.9 TB, the storage space vanished! Yes, vanished.  <\/p>\n<p>After invoking the Storage Space Manager, I discovered that the space was deemed &#8220;full&#8221; and that I was to add another disc. I also took a look at the volumes itself. Hmmh. The 320 GB disc was 100% filled, the 1 TB was at 32% and the 2 TB at 16%. And what are 32% of 1 TB and 16% of 2 TB? Why, 320 GB!  <\/p>\n<p>So, instead of creating a Parity storage space, it simply downsized every hard disc to the lowest denominator, i.e. 320 GB.  <\/p>\n<p>Which means that there are two massive problems here:  <\/p>\n<ol>\n<li>It&#8217;s lying about the remaining capacity (which is confusing in itself: The manager talks about the storage space having a 2 TB capacity, but directly above it talks about a 3.01 pool capacity?)\n<li>It also gives no warning when the real capacity is reached and the pool is deemed &#8220;full&#8221;. It simply takes the pool offline (instead of, say, reverting to a &#8220;read-only&#8221; mode with a warning) and you have to bring it online manually. Not fun.<\/li>\n<\/ol>\n<\/blockquote>\n<p>and later, from another user:<\/p>\n<blockquote>\n<p>Today while I copied data over to it, it once again reached &#8220;full&#8221; status and turned itself &#8220;offline&#8221; &#8211; but this time it won&#8217;t come back &#8220;online&#8221; &#8211; it changes right back to &#8220;offline&#8221; as soon as I try to bring it online&#8230;&nbsp; So essentially I cannot access any of the data on the drive anymore.<\/p>\n<\/blockquote>\n<p>or <a href=\"http:\/\/helgeklein.com\/blog\/2012\/03\/windows-8-storage-spaces-bugs-and-design-flaws\/#comment-6701\" target=\"_blank\">this<\/a> (which likely refers to the RP) \u2013 the <a href=\"http:\/\/helgeklein.com\/blog\/2012\/03\/windows-8-storage-spaces-bugs-and-design-flaws\/#comment-6701\" target=\"_blank\">article<\/a> to which it comments is worth a read too.<\/p>\n<blockquote>\n<p>I\u2019ve run into a major problem with storage spaces. My storage space is full. Having a full storage space puts it into an error state, and it goes offline. You can click \u201cBring online\u201d but it immediately goes offline again.  <\/p>\n<p>So, I can\u2019t free space on it, because I can\u2019t get it online to delete stuff. And, more importantly, I can\u2019t get anything off of it because it won\u2019t stay online.  <\/p>\n<p>It seems my only option is to add three drives, as I had it set to parity. The only problem? I don\u2019t have three more drives to add.<\/p>\n<\/blockquote>\n<p>Even bugs in in the RP worry me. Storage is so fundamental that I would expect a feature like this to be 100% solid early in the release cycle, or pulled.<\/p>\n<p><strong>Update<\/strong>: It now seems to me that Storage Spaces is working as designed (phew!) though it is understandable that users are confused.
