How will changing drives affect RAID5
Posted on 2010-01-07
I have an interesting question I am hoping someone can shed some light on. I have a Sun blade x6240 with an Adaptec RAID Expansion Module. There are four 146G drives configured in a RAID5 array. There is one logical drive set up.
I want to increase my storage capacity, and my question is, what will happen if I do the following:
Remove one 146G drive, and replace it with a 300G drive and let the RAID array rebuild.
Remove another 146G drive, and replace it with a 300G drive and let the RAID array rebuild.
And so on, until all four drives are 300G drives.
I am assuming that the system will now show that there is one logical drive that is 435G with 435G drive space as unpartitioned.
Am I correct in this assumption?
Thanks in advance for any information on this.
