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 0.00 0 0.00 0.00 0 0.00 4.50 107 0.47 0.00 0 0.00 4.51 98 0.43 0.00 0 0.00 4.50 116 0.51 0.00 0 0.00 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?
