I have a Cluster Disk under Failover Cluster Manager -> Storage -> Disks with 5.46TB of capacity, but when I click on it, it shows the volume with only 1.36TB.

Not sure how to increase the Volume.

    Hi,

    Please try to "extend the file system" directly, check if it could help. If seems we have extended the disk perviously, while the file system hasn't been extended.

    DISKPART
    List volume
    select volume 5
    Extend file system

    Best Regards,
    Anne

    Hi,

    1.The “Capacity” shows full disk size, the CSV volume size shows the volume formatted in disk manager.

    2.If we want to extend the CSV volume, we may follow the steps below.

    1) On the owner node of the CSV, please open CMS as administrator.

    2) Please enter the following command in CMD.

    diskpart
    list volume
    select volume <csv volume>
    extend
    extend filesystem

    3) After then, check if the CSV volume is extended in the FCM.

    Here is an article about how to extend CSV, for your reference.
