Hi all,
Is it possible to setup a RAID 5 array using different size disks? Such as hda
9GB, hdb 36GB, hdc 40GB, hdd 80GB, hde 80GB.
What are the impact and consequences?
Thank you very much,
Apart from comments by others re sizing, trying to use both disks on an
ATA connector at the same time serious hurts performance. As root, try this:
hdparm -t /dev/hda&
hdparm -t /dev/hdb
The ampersand is important.
I imagine you can play games with lvm and create equal-sized virtual
volumes, but again, watch that performance fall off.
You can address the first performance problem by adding ATA disk
controllers on PCI cards.
