selectively clear device disk cache?

[Bruce Lysik]

Hi guys,

I have this spewing in my traffic.out:

[May  1 09:23:11.564] Server {0x2afe89312700} WARNING: cache directory overflow 
on '/dev/sdd' segment 0, purging...
[May  1 09:23:11.565] Server {0x2afe89312700} WARNING: cache directory overflow 
on '/dev/sdd' segment 0, purging...

Is there any way I can just clear /dev/sdd, and not all the other devices? 

Thanks.
