Functions

func FilesystemCreateWithArgs 

func FilesystemCreateWithArgs(l []string) funcopt.O

FilesystemCreateWithArgs defines the shlex splitted list of arguments to prepend to the command.

func FilesystemCreateWithQuota 

func FilesystemCreateWithQuota(size *int64) funcopt.O

FilesystemCreateWithQuota Limits the amount of space a dataset and its descendents can consume. This property enforces a hard limit on the amount of space used. This includes all space consumed by descendents, including file systems and snapshots. Setting a quota on a descendent of a dataset that already has a quota does not override the ancestor's quota, but rather imposes an additional limit.

func FilesystemCreateWithRefQuota 

func FilesystemCreateWithRefQuota(size *int64) funcopt.O

FilesystemCreateWithRefQuota Limits the amount of space a dataset can consume. This property enforces a hard limit on the amount of space used. This hard limit does not include space used by descendents, including file systems and snapshots.

func FilesystemCreateWithRefReservation 

func FilesystemCreateWithRefReservation(size *int64) funcopt.O

FilesystemCreateWithRefReservation is the minimum amount of space guaranteed to a dataset, not including its descendents. When the amount of space used is below this value, the dataset is treated as if it were taking up the amount of space specified by refreservation. The refreservation reservation is accounted for in the parent datasets' space used, and counts against the parent datasets' quotas and reservations.

If refreservation is set, a snapshot is only allowed if there is enough free pool space outside of this reservation to accommodate the current number of "referenced" bytes in the dataset.

func FilesystemCreateWithReservation 

func FilesystemCreateWithReservation(size *int64) funcopt.O

FilesystemCreateWithReservation is the minimum amount of space guaranteed to a dataset and its descendents. When the amount of space used is below this value, the dataset is treated as if it were taking up the amount of space specified by its reservation. Reservations are accounted for in the parent datasets' space used, and count against the parent datasets' quotas and reservations.

func FilesystemDestroyWithNode 

func FilesystemDestroyWithNode(s string) funcopt.O

func FilesystemDestroyWithRecurse 

func FilesystemDestroyWithRecurse(v bool) funcopt.O

FilesystemDestroyWithRecurse recursively destroys all clones of these snapshots, including the clones, snapshots, and children. If this flag is specified, the FilesystemDestroyWithTryImmediate flag will have no effect.

func FilesystemDestroyWithRemoveSnapshots 

func FilesystemDestroyWithRemoveSnapshots(v bool) funcopt.O

FilesystemDestroyWithRemoveSnapshots forces an unmount of any file systems using the unmount -f command. This option has no effect on non-file systems or unmounted file systems. TODO: fix above doc ?

func FilesystemDestroyWithTryImmediate 

func FilesystemDestroyWithTryImmediate(v bool) funcopt.O

FilesystemDestroyWithTryImmediate destroys immediately. If a snapshot cannot be destroyed now, mark it for deferred destruction.

func FilesystemMountWithOverlay 

func FilesystemMountWithOverlay(v bool) funcopt.O

FilesystemMountWithOverlay performs an overlay mount. Allows mounting in non-empty mountpoint.

func FilesystemRenameWithNode 

func FilesystemRenameWithNode(s string) funcopt.O

func FilesystemRenameWithRecurse 

func FilesystemRenameWithRecurse(v bool) funcopt.O

PoolCreateWithVDevs defines the list of block devices paths to add to the pool.

func PoolDestroyWithForce 

func PoolDestroyWithForce() funcopt.O

PoolDestroyWithForce forces any active datasets contained within the pool to be unmounted.

func PoolExportWithForce 

func PoolExportWithForce() funcopt.O

PoolExportWithForce forcefully unmounts all datasets, using the unmount -f command. This option is not supported on Linux.

func PoolImportWithCacheFile 

func PoolImportWithCacheFile(s string) funcopt.O
