Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Oracle Solaris ZFS File System (MOSC)

ZFS space reporting, snapshots, clones and how NFS deals with it

Jan 18, 2017 12:24PM in Oracle Solaris ZFS File System (MOSC)

This Blog article, tries to address these questions:

How can I tell how much storage a file uses?
How does that change with compression or snapshots?
How can I tell how much space is still available in a filesystem?
If my filesystem is NFS living on a ZFS storage array (or a Solaris system running NFS on ZFS), are the numbers shown by NFS and ZFS consistent? How do I tell?
