assuming that sda is the working disk and sdb is the new, unformatted and
unpartitioned disk. So if hte machine breaks, I can get the new disk and put
in a new machine and everything should work. This server is doing firewall
and openvpn, etc, no X, no fancy stuff. Is this going to work? What do you
guys think?
I think the remote system should run off of a big compact flash card
and associated SSD, with the config and data files backed up to an
attached thumb drive.
How big is this system?
How much storage?
How HA is "HA"?
Hello,
I think it would be useful to know more about the filesystem
estructure, i.e, LVM, softRAID, etc...
Anyhow, if you can have HDs swapped, you can also have a live CD
played, do you?
And budget. Budget's *always* important.
For example, with a high-enough budget, you could build a
hardware-controlled RAID-1 hot-swap system where when a disk dies, a
user pulls it out and the controller automatically rebuilds the mirror.
But that's a B-52 to kill a mosquito...
