Humm, I didn't notice the raid0 above. Yup, thats a disaster looking
for a place to happen, so I'll second the antiraid(0 at least)
sentiments. Definitely a bad dog, no bisquit scenario.
As it is, if I lose that $120 commodity drive, I've lost my /var
partition and all my backups. But a 2 hour drive to Circuit City for
another (probably even bigger than 200GB), 20 minutes to install it,
10 minutes to fdisk it & mke3fs it, a run of my script to re-create
the amandatapes partitions contents, and I'm back in business after a
4 day dumpcycle to get fulls of everything again. I could even
reassign /var to another smaller unused partition on hda temporarily
and continue while I'm driving that 70 mile round trip to get the
other drives replacement.
I'd moved /var to a seperate spindle because I once had a write error
that made the whole disk read-only (bleeding edge kernel early in the
2.6 series). The error couldn't be logged, so it was a chicken and
egg situation. Moving /var is hopefully insurance against a repeat
of that scenario.
