Data Deduplication on Volume with friendly name

I am trying to disable data deduplication on a storage spaces direct server and I've disabled it on the windows admin center but I believe I need to run a command "Start-DedupJob -type Unoptimization -Volume X -Full" which I don't have a drive letter for the volume, only a friendly name. How would I disabled this for the FriendlyName FSLogix?

PS C:\Windows\system32> Get-Volume

DriveLetter FriendlyName FileSystemType DriveType HealthStatus OperationalStatus SizeRemaining Size


C NTFS Fixed Healthy OK 330.52 GB 371.4 GB
Recovery NTFS Fixed Healthy OK 481.29 MB 499 MB
FAT32 Fixed Healthy OK 69.18 MB 95 MB
FSLogix CSVFS_ReFS Fixed Healthy OK 1.07 TB 2.5 TB
ClusterPerformanceHistory ReFS Fixed Healthy OK 10.7 GB 11.94 GB

Thank you

I think I found out how to get the volume as it's referenced by c:\xxxx\xxxx

However I'm still seeing PID 4 processes with dedup running, how can I completely stop it from running and get rid of it?

Here are some things I see

Hello,

Thank you for your question.



Based on my understanding, to turn off Data Deduplication for the volume, we need to run the UnOptimization job first. Then you could disable DedupVolume

Also , We have a similar subject with a problem similar to this, I recommend that you consult it to better understand how to solve it, go to it on the link below:
