TrueNAS 11.3-U5, multiple Rsync process causes CPU usage high

[joesnow1234]

Hi, community, we saw many rsync processes that caused CPU higher than usual.
There are no related rsync tasks and corn jobs, and Rsync is disabled and stopped.

So where do these processes come from ? Any internal task that spawns these rysnc processes ?

rsync --server --sender -vlLogDtprze.iLsfxC --bwlimit=1024 . /var/log/

That is crazy. Do you know if there's a jail that perhaps is triggering rsync tasks?

 

[joesnow1234]

unfortunately, there isn't any jail in my environment. Therefore it's fairly weird.

Maybe there is some operation ongoing on "System / System Dataset" ?

The default setting on "System / System Dataset" is 'syslog', according to https://www.truenas.com/docs/core/coretutorials/systemconfiguration/settingthesystemdataset/
this is suspicious, does this implement by 'rsync' ?

 

[winnielinnie]

I don't believe the syslog has anything to do with spawning 30+ rsync processes.

You probably don't want to hear this, but why not upgrade to the latest TrueNAS Core (or "sidegrade" to SCALE)?

FreeNAS 11.3 is quite old...

ok, thanks.
