Hi,
Does anyone know the difference between zpool iostat and iostat?
dd if=/dev/zero of=/test/test1/trash count=1 bs=1024k;sync
pool only shows 236K IO and 13 write ops. whereas iostat shows a correctly meg
of activity.
zpool iostat -v test 5
capacity operations bandwidth
pool used avail read write read write
