disk_event_handler: disk event handler called for change

[gbeddow]

Starting yesterday morning, several of these pop up in the syslog every few minutes:

# cat /ReadyNAS-Volume/rsyslog/syslog
...
Feb 14 11:42:04 Netgear-RN202 disk_event_handler: disk event handler called for change

And I see disk_event_handler here:

# which disk_event_handler
/usr/bin/disk_event_handler

I've tried rebooting, stopping & restarting antivirus scanning, a volume defrag, volume scrub and volume balance, but it continues unabated.

This is an RN202 running the latest 6.6.1.

Any idea what's causing this?

Solved. On a whim I did this:

# service webmin stop

and the messages stopped.

Not even sure whether I'll keep webmin around - I was evaluating it. What's especially odd is that several days had elapsed between installing it and when the messages started, but whatever. 🙂

Since then I've run a disk test (took about 6 hours) that didn't find anything, and the "disk event handler called for change" messages continue.

/usr/bin/disk_event_handler is just a link to rnutil, but the latter is a poorly documented utility.

Usually I'm pretty good at digging into stuff like this, but so far come up empty.

Any suggestions out there?

Hello gbeddow,

You might want to try 6.7.0-T158 (Beta 1).
