Hello, I'm trying to figure out why I'm getting about 10MB/s scrubs, on a pool
where I can easily get 100MB/s. It's 4x 1TB SATA2 (nv_sata), raidz. Athlon64
with 8GB RAM.
Here's the output while I "cat" an 8GB file to /dev/null
r...@solaris:~# zpool iostat 20
capacity operations bandwidth
pool alloc free read write read write
---------- ----- ----- ----- ----- ----- -----
rpool 123G 26.0G 2 5 206K 38.8K

tera 3.04T 598G 1.53K 7 195M 20.9K

and here's what happens when I'm scrubbing the pool:

---------- ----- ----- ----- ----- ----- -----
rpool 123G 26.0G 1 0 130K 0
tera 3.04T 598G 88 0 10.5M 0
---------- ----- ----- ----- ----- ----- -----
I'd be glad to provide any info you might need.
Thanks.
