Bring it down, really?

I think monitor would just complain that it couldn't write to a
device. I suppose you could have problems if your recording partition
was also your system partition, but that would be true for any
application, such as apache web activity logs.

This would be channel and system independent. For instance i/o
blocking could cause problems but why would it affect simple non-mixed
audio, like simple bridged Dahdi channels?

If a non-system hd fills, calls will go on normally.
Port mirroring seems like a pretty heavy-handed way to do call recording.

How about asterisk, writing to a ramdisk for recordings, and every
five minutes or so syncing off the completed recordings to a SAN? (You
may have guessed I did this, and pushed it past 60 simultaneous
recordings).
