Storage Checkpoint Administration

2. Create four data Storage Checkpoints on this file system, note the order of creation, and list them:
# fsckptadm create oldest /mnt0
# fsckptadm create older /mnt0
# fsckptadm create old /mnt0
# fsckptadm create latest /mnt0
# fsckptadm list /mnt0
/mnt0
latest:
ctime = Mon 26 Jul 11:56:55 2004
mtime = Mon 26 Jul 11:56:55 2004
flags = largefiles
old:
ctime = Mon 26 Jul 11:56:51 2004
mtime = Mon 26 Jul 11:56:51 2004
flags = largefiles
older:
ctime = Mon 26 Jul 11:56:46 2004
mtime = Mon 26 Jul 11:56:46 2004
flags = largefiles
oldest:
ctime = Mon 26 Jul 11:56:41 2004
mtime = Mon 26 Jul 11:56:41 2004
flags = largefiles
3. Try to convert synchronously the "latest" Storage Checkpoint to a nodata Storage Checkpoint. The
attempt will fail because the Storage Checkpoints older than the "latest" Storage Checkpoint are data
Storage Checkpoints, namely the Storage Checkpoints "old", "older", and "oldest":
# fsckptadm -s set nodata latest /mnt0 UX:vxfs fsckptadm: ERROR: V-3-24632: storage
checkpoint set failed on latest. File exists (17)
4. You can instead convert the "latest" Storage Checkpoint to a nodata Storage Checkpoint in a delayed or
asynchronous manner. If you list the Storage Checkpoints, you will see that the "latest" Storage
Checkpoint is marked for conversion in the future
