Low Disk Space Alert on MYSERVER
Tristan
I'm getting this alert every day now, but when I look at the drives they all
have gigabytes of free space left. I can't find a way to find
HarddiskVolume10 either. I've tried looking in Computer Management - Disk
Management, but haven't found any clues.
No errors are showing in Event Viewer either for this problem.
Here is the contents of the alert:
Alert on MYSERVER at 20/03/2006 9:06:25 a.m.
The following disk is low on free disk space. Low levels of free disk space
can cause performance problems and prevent users from saving files on the
disk.
Drive Letter: HarddiskVolume10
Free Disk Space: 0.000000. MB
% Free Disk Space: 0.000000.%
Drive Letter: HarddiskVolume9
Free Disk Space: 0.000000. MB
% Free Disk Space: 0.000000.%
You can disable this alert or change its threshold by using the Change Alert
Notifications task in the Server Management Monitoring and Reporting
taskpad.
Any Ideas?
Thanks

on an ext USB HD. If so, I will post more info. (Too detailed to write
up if this does not apply to you.)

OK. In my case, there was one ext USB HD being used for SBS backups
only. Something went wacko - never did discover what, and the problem
never recurred. Here is what I did. Your mileage may vary, so adapt as
needed.
* If you have enough disk space on the server's internal disks, copy any
files that you can't afford to lose to an internal disk. In my case, I
just copied the most recent backup file (of the 5 on the HD). (The
server's disks were RAID 1, so the probability of a simultaneous failure
while doing this recovery work was small.)
* Use Device Manager to UNinstall the USB components supporting the ext
HDs. They will probably be shown as something like "USB Mass Storage
Device".
* Power down the HDs and disconnect the USB cables.
* In my case, a server reboot was not required. But if you are in a
position to conveniently do one, this would be the time.
* Reconnect the USB cables and power up the HDs. They should be
recognized by the server. If not, try rebooting the server (if you have
not already done so).
* Reformat the ext HDs. (This is why you saved files, above.) I think
I opened a command prompt and used the FORMAT command, although doing
this from Windows Explorer should work. A Quick Format won't do - you
need to REALLY format the HDs.
* Recreate ext HD folders if needed and copy back the files you saved.
If you are using the HDs for backup, you should manually recreate the
<drive>:\Backup Files folder which SBS backup expects. (Normally
created by the Configure Backup wizard.)
* If possible, try a test backup if you are using the HDs for backup (to
get rid of the NTDS Replication errors).
OPTIONAL: Assuming all that worked, you can change the Low Disk Space
Alert to be volume-specific. By default, SBS has only a single alert
for all drives. To configure an alert for each volume:
* On the server, launch the Health Monitor (Start | Administrative Tools
| Health Monitor).
* Navigate to Health Monitor | All Monitored Computers | <server> |
Small Business Server Alerts | Core Server Alerts
* Right-click Core Server Alerts and select New | Data Collector |
Performance Monitor
* General Tab:
- Name: "Low Disk Space - Vol x" (x=vol to be monitored, such as C, D,
etc.)
* Details Tab:
- Object: browse to LogicalDisk
- Counter: select % Free Space, Megabyes, and Name
- Instance: browse to LogicalDisk.Name="x:" (x=vol to be monitored)
* Actions Tab: should already have 2 entries: "Send e-mail with
monitoring alert" and "Store alert in monitoring database (with instance
name)", both set to Critical and every 24 hours.
* Schedule Tab:
- Collection Days: select every day
- Collection times: select All day
- Collection internal: select Every 1 minute
- Total samples for average collection: 10
* Message Tab: Something similar to:
- - - - -
The following disk is low on free disk space. Low levels of free disk
space can cause performance problems and prevent users from saving files
on the disk.
Drive Letter: %InstanceName%
Free Disk Space: %EmbeddedCollectedInstance.FreeMegabytes% MB
% Free Disk Space: %EmbeddedCollectedInstance.PercentFreeSpace%%
You can disable this alert or change its threshold by using the Change
Alert Notifications task in the Server Management Monitoring and
Reporting taskpad.
- - - - -
* Click OK to complete the alert.
* Create additional alerts as required for other volumes.
* [Optional: Delete the generic (total) Low Disk Space alert.]
* Close Health Monitor; launch Server Management if it is not already
running.
* Standard Management | Monitoring and Reporting | Change Alert
Notifications
* Performance Counters tab: You should see the volume-specific alerts
you created. You can set threshholds individually for each volume by
selecting the alert and clicking the Edit button.
Hope this helps.

I can believe that, although in my case, there was only one drive that
was not being removed. Very mysterious - only happened with this
client, and only once with them.
(This client started with a tape drive and I added the external HD. The
tape was still used for a weekly backup that was taken offsite, with the
HD being used for the other days.)
