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. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
