Sorry if I'm adding more to clutter to the Storage Spaces conversation, but I can't seem to find an answer to an issue I have.
While doing an inital test of Storage Spaces, I did the following:
- With two 3TB HDs, created a mirrored pool with a max size VHD (2.73TB)
- Added a single 2TB drive to the pool (1.82TB)
- Extended the VHD for a total of (3.64TB = 2.73 + half of 1.82)
Now, this makes sense to me and was what I assumed should happen. With this test done, I went and tried to do my final setup:
- Using two 3TB HDs, created a mirrored pool with a max size VHD
- Copied 3TB of data from a third 3TB HD onto the VHD
- Wiped the third 3TB HD
- Added the third 3TB drive to the pool
- Tried to extend the VHD, but everything was grayed out and VHD remained at 2.73TB
So what happened? Why did this not behave like before (ie, the VHD be extended to approx 4TB = 2.73 + half of 2.73), which is what I wanted. I'm trying to add the third drive so that I have space to copy more data into the pool from a fourth 3TB HD (which I also intend to add to the pool for a total of 6TB with 4 mirrored HDs). Now I'm confused as to what will happen if go ahead and add the fourth 3TB drive (after backing up the data elsewhere). Will this get me to my desired end result (6TB with 4 mirrored HDs) or will this only get me a 2.73TB VHD mirrored across 4 HDs?
I'm at work now and forgot how many columns were in the orignal pool setup. Will I need to rebuild this whole thing and use powershell instead to set the number of columns correctly (I assume it needs to be forced into 2 columns). Can anyone clarify what I need to do for me to get my desired result before I have to waste another day backing up data to rebuild this?
