In Debian, is it only the loss of / that requires a reinstall? What
happens if /var (especially /var/lib) or /usr get corrupted? Doesn't
that also make the system extremely difficult/time-consuming to restore?
If I were to get a second 80 GB SATA drive so that I could raid1 /,
might I just as well have the whole base system on raid1?
I would then have something like this:
Disk a:
Part: Size:
1 64MB
5 remainder
Disk b:
Part: Size:
1 64 MB
5 remainder
a1 and b1 raid1 to make md0 and mounted as /boot
since can't resize md0, can anyone imagine /boot ever needing
more than 64 MB to hold 2 kernels (old and new)?
Boot will be via grub installed on both drive's mbrs for
auto-failover booting.
a5 and b5 raid1 to make md0 which becomes pv0 of vg0
lvs made for rest of base system including /
This also ends up with swap in a lv on raid1 so drive crash shouldn't
crash the system.
If this looks good, do the d-i menus let me start out with a degraded
raid1 with only one drive, and add the second drive later?
Thanks to your patient help, I'm gradually getting my head around this
new world. Thank you.
Doug.
