Normally it is ok to use hastctl for scripting. Do you have it hang forever of just for a few seconds? Usually hanged hastctl means that hastd master process is waiting for its worker (either its response or exit). Could you provide logs from both master ans secondary? Also you might want to run hastd with -d to make it more verbose. > Also, I don't know how to detect an error of writing to local device from > hastd. > Does anyone know about it? Currently only by monitoring logs. It looks like a good idea to add error counters to hastctl statistics output... > Thanks, > Daisuke Aoyama > > -- the procstat shows like this: > [root@nas4free-nodeb /tmp]# procstat -ka|grep hast > 11668 100069 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep kern_wait sys_wait4 > amd64_syscall Xfast_syscall > 17981 100406 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep do_wait > __umtx_op_wait_uint_private amd64_syscall Xfast_syscall > 17981 100559 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep soreceive_generic kern_recvit > recvit sys_recvfrom amd64_syscall Xfast_syscall > 17981 100560 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep soreceive_generic kern_recvit > recvit sys_recvfrom amd64_syscall Xfast_syscall > 17981 100561 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep do_wait > __umtx_op_wait_uint_private amd64_syscall Xfast_syscall > 17984 100078 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep do_wait > __umtx_op_wait_uint_private amd64_syscall Xfast_syscall > 17984 100562 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep soreceive_generic kern_recvit > recvit sys_recvfrom amd64_syscall Xfast_syscall > 17984 100563 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep soreceive_generic kern_recvit > recvit sys_recvfrom amd64_syscall Xfast_syscall > 17984 100564 hastd - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep do_wait > __umtx_op_wait_uint_private amd64_syscall Xfast_syscall > 18218 100145 hastctl - mi_switch > sleepq_catch_signals sleepq_wait_sig _sleep soreceive_generic kern_recvit > recvit sys_recvfrom amd64_syscall Xfast_syscall > > [root@nas4free-nodeb /tmp]# procstat -ta|grep hast > 11668 100069 hastd - 0 120 sleep wait > 17979 100557 hastd - 2 120 sleep g_waitid Strange, I don't see 17979 process in procstat -k output.
