I have ba RAID-5 server (Linux) with 4 @ 18 GB SCSI drives in RADI-5, yielding some 50+ GB. One of the drives just died.
I noticed replacement 18 GB drives are not much cheaper than 36 GB. I wonder if I can buy new 36's and somehow upgrade
the entire reaid array to get more storage ?
I understand if I replace one of the drives with a larger one,
that drive's capacity would be reduced to that of the others
(eg only 36 GB). So even if I replace each old drive one at a time with a larger drive, rebuilding each time, I still won't get a higher capacity. Correct ?
So is it true the only way to upgrade the capacity is to remove all the old drives, put in the new drives, anbd restore from tape ? Ort is there another way that does not depend on restore from tape?
Thanks in advance
