While monitoring various deivces I noticed that the results from mount -v
and iostat weren't the same. I'm "assuming" that iostat is
the more
accurate due to geom tasting (on a memory disk?), or is something else at
play?
Simplest example:
mount -v -t nonullfs |grep md7; iostat -d -c 1 -tda -x -I|grep md7
/dev/md7 on /s (ufs, asynchronous, local, noatime, writes: sync 4 async
268, reads: sync 1215 async 0, fsid 8abeba5db4f71f26)
md7 1244.0 293.0 0.0 0.0 0 0.0
0.0
