Thanks to everybody. I recall discussion from several years ago on the benefits of
software over hardware RAID. I had completely forgotten about UPS for this new machine.
Btw, what happens if power goes out (and I do not have UPS)?
Btw, I still stick to ext4, largely because of inertia (and because I have used lvm in the
past and hated its naming conventions, I think, but there were also other limitations that
I do not now recall) and have stayed away from zfs or btrfs or lvm. I am not sure what to
do now. Clearly, things have moved far on.
Thanks,
Ranjan

Software RAID works very well on modern hardware. You do want to make sure
a power
outage can't cause a shutdown before the RAID is safely dismounted.
Ideally a your site
has a reliable generator and your server has a UPS that can hold power
while waiting for
the generator to come online and also long enough to ensure a clean
shutdown when the
generator fails.
