here is the thing, I created a txt file with string used python first, so far, everything is normal. then used ipmitool to reboot, but the txt file is empty when OS boot up.
with open('test.txt','a+') as f:
f.write('test')
os.system('sudo ipmitool chassis power reset')
I have no idea how this happened, is there any possible reasons may cause this? BTW, if manually execute ipmitool, it's normal too.
add sync command before ipmitool chassis power reset. It will flush buffers to permanent storage.
sync; ipmitool chassis power reset
