Ok, I have that fs_mark test running here. How far did yours get before
it stopped?

I had gone (in heavy fsync mode) up to about 8 million files on a 1TB
s-ata disk:
17 8064000 20480 5.6 15301404
This is the new (no system sync() call) Chris special fs_mark. The rate
had been quite reasonable, starting out at around 160 20k files/sec,
went under 100 files/sec at around 3 million files and then fell under
50 files/sec at around 7.5 million before hitting this really low speed
at just under 8 million.
Maybe it really was not hung, just extremely slow...
I'm at 6.9 million files so far on a 500GB disk, and not surprisingly, I
get 155 files/sec ;) My hope is that we're spinning around due to bad
accounting on the reserved extents, and that Yan's latest patch set will
fix it.

I can update & restart my test as well. It is an odd box (8 CPUs, only
1GB of DRAM and a single large 1TB s-ata drive). Hopefully useful in
testing out edge conditions ;-)
