Hi Alvin. I'm just wondering this: Is this true for software RAID aswell? My doubt is about sofware raid vs disk partitions..


Image you're using software raid and 1 disk fails. You somehow get alerted and , AFAIK, you
1 - shutdown the machine (ok, this if you don't have a hot-swap system)
2 - remove the failed disk
3 - insert a new, "fresh-from-the-store" disk
4 - power-up


Now, if this was a hardware raid solution, yes I believe the array will self-contruct again. My question is if, with these steps you'll have a software RAID system resync'ing the array... or you need to do extra steps like:
5 - partition the disk with same partition layout as the removed one


and only after this step the array can re-construct .. What's your experience on this?

Thanks
Joao Clemente
