A txt file monitoring.env contains a list for exclude windows disk of monitoring

k:\\data\\sql\\:DISK:OFF
k:\\data1\\sql\\:DISK:OFF

With the folowing code, only the first line k:\\data\\sql\\:DISK:OFF is read :
$MONITORING = gci -Recurse ($CONF_INST_CONFIG) -in *.env
$EXCLUDE_DISK=get-content $MONITORING | where-object {$_.contains(":DISK:OFF")} |Foreach-Object {$_ -replace ":DISK:OFF", ""} -ErrorAction silentlycontinue
if ($EXCLUDE_DISK -ne $null) {
$LIST_EXCLUDE_DISK =  [string]::join('', $EXCLUDE_DISK) + ''
}
$LIST_DISK_1 = Get-WmiObject Win32_Volume -Filter "DriveType!='5' and not label like '%OS%'" |where-object {$_.name -notmatch $LIST_EXCLUDE_DISK}

How can I resolve this?

Thanks

I think it's reading everything just fine.  It's what you're trying to do afterward that is having problems.
What are you trying to do with the line below?
$LIST_EXCLUDE_DISK =  [string]::join('', $EXCLUDE_DISK) + ''
That just gives you a result like "k:\\data\\sql\\k:\\data1\\sql\\".

And what are you trying to filter with the Where-Object in
$LIST_DISK_1 = Get-WmiObject Win32_Volume -Filter "DriveType!='5' and not label like '%OS%'" |where-object {$_.name -notmatch $LIST_EXCLUDE_DISK}  ?

With list_exclude_disk Disks are separeted with space.
With where object, I try to build list_disk_1 without Disks in list_exclude_disk

If you wanted them separated by a space you could do either of the following:
$LIST_EXCLUDE_DISK =  [string]::join(' ', $EXCLUDE_DISK)
$LIST_EXCLUDE_DISK =  $EXCLUDE_DISK -join " "

Open in new window

But I don't see what that gets you.  You don't have any volumes with the name "k:\\data\\sql\\ k:\\data1\\sql\\" do you?  Or even "k:\\data\\sql\\"?  I'm quite certain you're just looking to get the drive letter like "k:\".

If I'm correct you can use the following:
$MONITORING = gci -Recurse ($CONF_INST_CONFIG) -in *.env
$EXCLUDE_DISK = @(Select-String $MONITORING -pattern "^([A-Z]:\\).+:DISK:OFF" | ForEach-Object {$_.matches} | ForEach-Object {$_.groups[1].value} | Select -Unique)
$LIST_DISK_1 = Get-WmiObject Win32_Volume -Filter "DriveType!='5' and not label like '%OS%'" | Where-Object {$EXCLUDE_DISK -notcontains $_.name}

Open in new window

BTW, in my testing if you want to return drives that don't have a label you would have to adjust the WMI filter to include "label = NULL".

For answer :
But I don't see what that gets you.  You don't have any volumes with the name "k:\\data\\sql\\ k:\\data1\\sql\\" do you?  Or even "k:\\data\\sql\\"?  I'm quite certain you're just looking to get the drive letter like "k:\".

--> I have the volumes k:\\data\\sql\\ k:\\data1\\sql\\ but I want to exclude them from $LIST_DISK_1.

I have tested the code.
The result from $EXCLUDE_DISK is k:\ and not k:\\data\\sql\\ k:\\data1\\sql\\.

OK, if you have the volumes "k:\\data\\sql\\" and "k:\\data1\\sql\\", the below will exclude them.  I just changed the matching pattern slightly.
$MONITORING = gci -Recurse ($CONF_INST_CONFIG) -in *.env
$EXCLUDE_DISK = @(Select-String $MONITORING -pattern "^([A-Z]:\\.+):DISK:OFF" | ForEach-Object {$_.matches} | ForEach-Object {$_.groups[1].value} | Select -Unique)
$LIST_DISK_1 = Get-WmiObject Win32_Volume -Filter "DriveType!='5' and not label like '%OS%'" | Where-Object {$EXCLUDE_DISK -notcontains $_.name}

Sorry unless I'm mistaken I don't see any difference between the code in posted ID: 39208278 and the code in posted  ID: 39207137.

Correct.  If that works for you, it could even be simplified to "^(.+):DISK:OFF$".
