I have 4 RAID5 arrays. Three of the arrays were created using 3 physical disks. The fourth array was created using 4 physical disks. Each hdisk's physical partition size is 64 MB.
Will I have a problem down the road if I put these arrays all in the same volume group? There is a possibility that I might have part of logical volume A on a 4-disk RAID5 array and the rest of logical volume A on a 3-disk RAID5 array. Will mixing the arrays like this cause RAID5 problems? Or should I put the 3 three-disk arrays in their own separate volume group?
