I’m planning on building a new home server and was thinking about the possibility to use disc spanning to create matching disk sizes for a RAID array. I have 2x2TB drives and 4x4TB drives.
Comparison with RAID 5
4 x 4 TB drives
1 RAID array
12 TB total
4 x 4 TB drives & 2 x 2 TB drives
2 RAID arrays
14 TB total
5 x 4* TB drives
Several 4TB disks and 2 smaller disks spanned to produce a 4 TB block device
16 TB total
I’m not actually planning on actually doing this because this setup will probably have all kinds of problems, however I do wonder, what would those problems be?
I do not see why it will cause any problems with exception of stacking mapping layer. I wonder can LVM do it natively without adding intermediate block device of 2 x 2G?
