The following example shows the creation of a removable Storage Checkpoint
named thu_8pm on /mnt0 and lists all Storage Checkpoints of the /mnt0 file system:
# fsckptadm -r create thu_8pm /mnt0
# fsckptadm list /mnt0
/mnt0
thu_8pm:
ctime = Thu 3 Mar 2005 8:00:19 PM PST
mtime = Thu 3 Mar 2005 8:00:19 PM PST
flags = largefiles, removable
thu_7pm:
ctime = Thu 3 Mar 2005 7:00:17 PM PST
mtime = Thu 3 Mar 2005 7:00:17 PM PST
flags = nodata, largefiles
Removing a Storage Checkpoint
You can delete a Storage Checkpoint by specifying the remove keyword of the
fsckptadm command. Specifically, you can use either the synchronous or
asynchronous method of removing a Storage Checkpoint; the asynchronous
method is the default method. The synchronous method entirely removes the
Storage Checkpoint and returns all of the blocks to the file system before
completing the fsckptadm operation. The asynchronous method simply marks
the Storage Checkpoint for removal and causes fsckptadm to return immediately.
At a later time, an independent kernel thread completes the removal operation
and releases the space used by the Storage Checkpoint.
In this example, /mnt0 is a mounted VxFS file system with a Version 4 disk layout.
This example shows the asynchronous removal of the Storage Checkpoint named
thu_8pm and synchronous removal of the Storage Checkpoint named thu_7pm.
This example also lists all the Storage Checkpoints remaining on the /mnt0 file
system after the specified Storage Checkpoint is removed:
# fsckptadm remove thu_8pm /mnt0
# fsckptadm list /mnt0
/mnt0
thu_7pm:
ctime = Thu 3 Mar 2005 7:00:17 PM PST
mtime = Thu 3 Mar 2005 7:00:17 PM PST
flags = nodata, largefiles
# fsckptadm -s remove thu_7pm /mnt0
