Hello,
I've got a question about vinum. There are two scsi disks with vinum
stripe. Here is a vinum config:
drive a device /dev/da2s1e
drive b device /dev/da3s1e
volume vinum0
plex name vinum0.p0 org striped 1024s vol vinum0
sd name vinum0.p0.s0 drive a plex vinum0.p0
len 34791424s driveoffset 265s plexoffset 0s
sd name vinum0.p0.s1 drive b plex vinum0.p0
len 34791424s driveoffset 265s plexoffset 1024s
# uname -sr
FreeBSD 4.1-STABLE
There are not any other fs on these disks. The problem is - when I run
iozone (iozone 4096 /logs/io0.tmp) I get a very strange result:
# iostat -d da1 da3 10
da1 da3
KB/t tps MB/s KB/t tps MB/s

4.49 117 0.52 0.00 0 0.00
4.50 111 0.49 0.00 0 0.00
....
You see, there is not activity on da3. Are there any explanations?
Thanks,
maxim
