Question

Friday, March 7, 2014 3:13 AM

I got this error in Windows Logs (Application) from Hyper-V host.
Please advise if this error is not normal, since the partition is partitioned with NTFS.

Event ID: 257

Event Source: Microsoft-Windows-Defrag

Event Description: The volume VOL1 (C:\ClusterStorage\Volume4) was not optimized because an error was encountered: This operation is not supported on this filesystem. (0x89000020)

Any help would be appreciated.

Is this guide can be applied to Windows Server 2012?

How do I manually and cleanly perform a disk defragmentation or use Chkdsk on a Cluster Shared Volume (CSV)?

so the solution is we have to manually defrag the CSV????

1) You can modify the task to put the volume into redirected mode before running the operation and get it our of redirected mode once the defrag is complete (using the PowerShell cmdlets referenced in the blog).

2) You can disable the task but the first option would be preferable...

Have a nice day !!!

Thanks for your reply Eugene Leitan,

Is this guide can be applied to Windows Server 2012?

I think this error raised because in Windows Server 2012 it has "Scheduled defragmentation" that defrag all disk....when it try to defrag the CSV...it fails....

so the solution is we have to manually defrag the CSV????
