They seem to be related to my iSCSI-shared zvols. Can we get a synopsis of these devices and where (within the data pipeline) iostat is getting these numbers?
Code:
root@freenas[~]# iostat -xz -w 3 -o extended device statistics device r/s w/s kr/s kw/s ms/r ms/w ms/o ms/t qlen %b nvd0 12 0 126.9 0.0 0 0 0 0 0 0 da1 25 27 232.6 378.0 12 0 110 7 0 25 da2 23 26 211.5 375.4 13 0 109 7 0 25 cbb8 1 0 6.8 1.5 0 0 0 0 0 0 cbb9 1 0 6.8 0.2 0 0 0 0 0 0 cbb10 2544 31 54846.8 683.3 0 0 0 0 0 30
