Let's assume the szenario of a 8-disk Storage Pool:
6x 4 TB HDD
2x 1 TB HDD
Now, a virtual Disk is created that uses a Mirrored-Layout and 4 Columns.
What will happen, once the written amount of data equals 1 TB per Disk?
Since the Drive is configured as double mirror with 4 Columns, will it:
- Stop accepting any data, since there is no 4th column available (The 1TB Disks are full)?
- Continue accepting data, but create a "pseudo-4-Column-Layout", where the actual 4th column is on the same disk as column 1,2 or 3?
- Switch to a 3 Column layout in order to utilize the remaining diskspace on disk 1-6? (If so, can the column count be restored later on, when adding more disks?)
- ...explode?
- Anyting else?
