CentOS Software RAID
Hi Experts!
I have 2 x 4TB HDD and the latest CentOS DVD installer.
1) How do I install software RAID 1
2) If one HDD fails, how will I know and will there be downtime/outage immediately?
3) Lastly will it auto re-build once I put a new 4TB HDD into the swap.
Thanks.

Will the system boot from a single 4TB hdd? Most won't. If your system won't boot from a single 4TB hdd, then it won't boot if that disk is part of a mirror either.

how do you see if it boots on a stand-alone 4TB disk??? You install LINUX and just take the defaults and find out. Or, if your machine does NOT have a UEFI bios, then no need to do the test. It won't work.

@dlethe Do I need to set anything in the UEFI bios?

@hkchris Thanks. How do I know if it has broken as in will it auto email me? A quick note also how do we know physically which disk broke? heh.
