I'm trying to get the total bytes written to disk in FreeNAS v9.10 running RAIDz2-0. I went under Reporting > Disk and could see output like:
In terminal I also tried
vmstat -p array which didn't offer data needed.
[root@freenas] ~# vmstat -p array procs memory page faults cpu r b w avm fre flt re pi po fr sr in sy cs us sy id 1 1 0 3890M 1881M 275 0 0 28 234 829 878 2078 1804 0 0 99
How do you get the total bytes written for FreeNAS?
iostat is what i should be using because
man iostat says "The first statistics that are printed are averaged over
the system uptime".
iostat -dI is showing:
[root@freenas] ~# iostat -dI da0 da1 da2 da3 KB/t xfrs MB KB/t xfrs MB KB/t xfrs MB KB/t xfrs MB 33.51 79317495 2595417.21 33.74 78641558 2591314.42 33.91 78170544 2588457.94 34.01 77875087 2586463.43
daX and "X" number is the disk, i'm wondering where the other 4 are.
