How do you recover from a full mirrored storage space? It's offline and won't go online again!

I have a pair of 500GB drives configured as a mirrored storage space, which is reported in the Manage Storage Spaces applet as:

 "Two-way mirror
493 GB
Using 929 GB pool capacity"

To test this thoroughly I've filled the storage space, and as expected (from what I'd read) Windows 8 automatically takes the drive offline. Disk Manager shows "The disk is offline because it is out of capacity".

Now, I'd like to be able to delete some files from the storage space, but as soon as I try to bring the drive online, it immediately goes offline again.

How do you get out of this situation?

Same issue here.

Anybody know how get it back online long enough to delete some files?

What kind of logic is this anyway.  The drive is full, so now you can't access it???  WTF?

I have the same issue, using 1 1Tb and 2 640Gb discs in a pool.

The pool is now reported as full and Offline!

I cannot set it Online at all, and I cannot add another disc to the pool.

How can I retreive the data in the pool to move it to other discs????

If you have two disks 500GB, then there are several possibilitis how to combine their capacity. You have mentioned MIRROR which mechanism that is doing copy of one disk to second disk on the fly. In this way you cannot reach capacity larger than capacity of one disk. This is RAID 1 and it allows for increase of security of your data. One disk fails and you have still one working disk.

Other configuration can extend the capacity for combination of two disks or even increase access speed (RAID 0), but your data are lost, when one disk fails. (That is why there are clever combinations of RAID 0 and RAID 1 that cover both, increased capacity, speed and security. This is a case of some server configurations.)
