volume-id: Identifies the volume that you want to snapshot. You can use the
lsvolume
command to find the identifier for each volume. -
--attributes
: Optionally specifies attributes for the volume snapshot.
Usage Notes
mkvolumesnapshot
command fails if the
specified volume supports Exascale Direct Volume
(EDV) attachments and Oracle Advanced Cluster File System (ACFS) is currently
mounted. To create a volume snapshot in this situation, you must either:
- Unmount the affected file system on all servers before you use
the
mkvolumesnapshot
command. Then, mount the file system again afterward. -
Use the Oracle ACFS command-line utility (
acfsutil
) to synchronize the file system and create the volume snapshot. On an EDV client node, run theacfsutil volsnap create
command as theroot
user and specify the ACFS mountpoint or EDV device.For example:
# acfsutil volsnap create /mnt/myacfs
