I have tow native zfs pools of a 2T harddisk of mirror 1 on my home desktop pc. But there are 658 kernel threads of z_fr_iss1,z_ioctl_iss z_ioctl_int z_zvol z_iput z_rd_int z_null_iss z_null_int z_cl_int z_cl_iss and etc.
I want to know whether it is normal in zfs file system.



lsmod |grep zfs
zfs 2692910 5
zunicode 331170 1 zfs
zcommon 55411 1 zfs
znvpair 89170 2 zfs,zcommon
spl 96165 3 zfs,zcommon,znvpair
zavl 15236 1 zfs



ps -Af |grep z_|wc
658 5266 40009
