Invalid Disk FreeSpace Value

[JTTrey3]

We have Operations Manager running in our enterprise, but are continually getting alerts for 1 server showing that the %Free Disk Space for all logical drives is ZERO

This is not correct, and we have been trying to figure out why.

Has anyone else seen this??

Is it by any chance an NT or W2K server? Disk performance counters, both logical and physical, diskperf.exe -Y, are only enabled by default on systems beyond Windows 2000.

It is Windows 2000

I ran diskperf w/o any options, and it said that both logical & physical counters were set to start at boot.

 

[X509]

It is possible that something did not enable properly. Would you be able to turn them both off, diskperf -N, reboot, turn them back on, diskperf -Y, and then reboot again? Just thinking out loud now, I wonder if it would help to turn the physical and logical on and off individually: diskperf –ND, diskperf –NV, diskperf –YD, diskperf –YV with a reboot after each one? Trying these with an administrative account, local or domain would be a good idea as well.

I shall try that tonight. I ran trace logs for the logical disk %Free Space counters and they showed up &quot;0&quot; as well.

Hopefully turning it off and back on will help. (with reboots in between)

 

[JTTrey3]

No dice. Disabeling and re-enabling the counters individually did not help.

The other thing which may be relevant: The drives showing&quot;0&quot; % Freespace are SAN Attached.

Is it by any chance an HP/Compaq array? I use the Compaq MOM Paq and it woks great! That may be an answer for you. Just curious, I don't have a SAN yet; can you drop to a DOS prompt and simply do a DIR and get the size and usage like a physically attached drive?

Did you ever get an answer?

I'm experiencing the same problem on a Dell PE2400 running W2K-SBS. I had to replace a disk on a RAID5 array and from that day I have had logical disk error:
