How to change SCCM reserve disk space for a DP

1) Run SQL query:

select SCR.ID, SCR.Name,SC.NalPath, SCR.Value3 from sc_sysresuse_property SCR join sc_sysresuse SC on SCR.SysResUseID = SC.ID where SCR.name = 'MinFreeSpace' and SC.NALPath like '%%' and SC.RoleTypeID = 3

get SCR_ID

2) Use the returned ID in step 1). Run the below query to update the 'MinFreeSpace' value.
update sc_sysresuse_property set value3 = 'set desired value in MB' where name = 'MinFreeSpace' and ID = ''
Example:
update sc_sysresuse_property set value3 =10240  where name = 'MinFreeSpace' and ID = xxxxxxxxxxxxx

3) Change registry value HKLM\software\Microsoft\SMS\DPreserveddiskspace to match the  number you used on step 2, eg: 10240. 

You don't have to reboot the DP.

Restart the SMS_SITE_Component_Manager service on SCCM site server.

It seems "October 2016 security monthly quality rollup" is causing the issue
KB3192392 for Windows 8.1 and Server 2012 R2
KB3185332 for Windows server 2012
KB3185330 for Windows server 2008 R2

Remove the KB and restart the SCOM server and it will be fixed.

Clustered task in Windows server 2012 R2 with 0x1 error

I tried to create a clustered task and got 0x1 error, according to M$ it means

0x1: An incorrect function was called or an unknown function was called. (ref: https://support.microsoft.com/en-us/kb/308558)
extra: https://msdn.microsoft.com/en-us/library/windows/desktop/aa383604(v=vs.85).aspx

This is the original script that generated 0x1 error

$action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "runme.ps1" -WorkingDirectory "E:\Shares\scripts"

E: is a clustered disk and I got 0x1 error when I execute the task manually.

Later I found that it has to do with execution policy, so I have changed it to

$action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "-executionpolicy bypass -file runme.ps1" -WorkingDirectory "E:\Shares\scripts"

and it ran without error.


Here is the complete script to create the task
$action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "-executionpolicy bypass -file runme.ps1" -WorkingDirectory "E:\Shares\scripts"
$trigger = New-ScheduledTaskTrigger -Daily -At 3pm
Register-ClusteredScheduledTask –Cluster filesharecluster –TaskName MyResourceSpecificTask –TaskType ResourceSpecific –Resource "cluster disk 2" –Action $action –Trigger $trigger


and this is what the runme.ps1 looks like, as you can see you can run dos command and powershell

dir c:\ | export-csv "e:\shares\scripts\result.csv"

somehow trying to to run bat file also generated 0x1 error, some suggested that the account that runs the task needs to be in "logon as a batch" job in local security policy but I have not tried it yet.
