Event Viewer Warnings


peterweb

Question

Windows Server 2016 Standard with Essentials Role. DrivePool version 2.2.0.737 BETA.

 

I have been seeing an issue with the File Distribution not Optimal. I just looked at Event Viewer and see a number of warnings for the DrivePool disk (disk 4)

 

The IO operation at logical block address 0x1 for Disk 4 (PDO name: \Device\0000002e) was retried.

The IO operation at logical block address 0x11 for Disk 4 (PDO name: \Device\0000002e) was retried.

The IO operation at logical block address 0x21 for Disk 4 (PDO name: \Device\0000002e) was retried.

 

This goes on for about 7 minutes every 10 -15 seconds after a clean restart of the server.   Looking back, I see this is a constant issue a few times a day.

 

Any suggestions on what I can look for.

These are completely normal, and even "expected".

 

For the DrivePool disk, we emulate a disk, so there are no "blocks" to be addressed.  This will always return errors (we don't want to add special handling here, because it could potentially cause weird issues... better to error out). 

 

However, the frequency of the errors is abnormal.  You should only see these once in awhile.  

 

Just in case, could you run this:
