[SOLVED] Two basic software RAID 1 questions

chrismurphy · 02-05-2011, 05:20 PM

I understand the software RAID partition types on two physical drives that will be paired must be set to the same size. However,

1. Do the physical drives themselves need to be the same size?

2. Do the physical drives need to use the same interface?

e.g. Can I setup mirroring with one 80G SATA, and one 320G PATA? (And is this reliable/stable?). The use is for an asterisk server which came with the 80G, I can't find anything smaller than 320G for the 2nd drive, and the free connector inside is PATA.

Thanks.

1. no, you need two block devices of the same size, but that can be a pair of equal partitions on unequal disks.

2. nope.
