RN102 - readynasd (loadavg) runaway cpu usage?
My ReadyNAS 102, running firmware 6.10.3, is currently thrashing its cpu. Here's the output from top: top - 18:50:39 up 16 days, 22:11, 1 user, load average: 1.87, 1.86, 1.89
Tasks: 143 total,...
I have RN104 and having same problem when netgear updated the NAS to the latest version. :smileysad: Hoping Netgear needs to release an update to fix the issue.
Sorry to hear that combathero32 . Likewise, I'm hoping for a fix, but in the meantime I'm working around the issue with a cron job. It runs every 15 mins and checks the time of the last entry in /var/readynasd/loadavg.dat. If that entry is older than 16 mins it emails me, so that I can I log in to restart the `readynasd` service. Coincidentally, it tripped for the first time in over a week just this morning.
Thanks for the inputs BrianTopp. I added shell script on cron.hourly directory to check loadavg updates and if it is outdated for an hour then the script will restart readynasd until Netgear found the fix for this one.
#!/bin/sh
if [ $(( $(date +%s) - $(stat -c "%Y" /var/readynasd/loadavg.dat) )) -gt 3600 ]; then
/bin/systemctl restart readynasd
fiI never thought to look at a thread view when readynasd hit 100% during a scrub, but I now wonder if that's not also caused by loadavg that, once something holds it up too long from doing what it wants to, it just starts using more and more CPU stacking up pending operations. I no longer run a NAS on which I have seen that issue, so I can't check. But maybe this is the clue Netgear needs to finally find and fix the problem.
Unfortunately, though, I see no replies at all from a Netgear person.
