Veritas™ File System 5.0.1 Programmer's Reference Guide

uint vxfs_ts_reclaim(char *mountpoint, uint64_t offset,
uint64_t length, int32_t volindex, uint64_t unit_size,
uint64_t *bytes_reclaimed, uint32_t flag)
This is a non-reentrant API. This API cannot be called when an instance of the
fsadm command or a reorg of the file system is running.
The pathname of the VxFS file system that is mounted on a
Veritas Volume Manager (VxVM) volume.
mountpoint
The offset in bytes in the volume from which to start
reclamation.
offset
The length in bytes from offset, up to which to reclaim free
storage.
length
The index of the volume in a volume set. When volindex has
a value of -1, all the volumes in the file system ignore offset
and length. On a non-multi-volume file system, volindex should
be zero.
volindex
The size in multiples by which the file system issues reclaim
requests to VxVM. Each Thin Provisioning array supports
reclamation by a factor of some unit size.
unit_size
Returns the number of bytes that the file system attempted
to reclaim. The value does not give an indication of the number
of bytes actually reclaimed.
