Then recreate it as a nodata Storage Checkpoint:
# fsckptadm -n create latest /mnt0
# fsckptadm list /mnt0
/mnt0
latest:
ctime = Mon Oct 16 12:06:42 2001
mtime = Mon Oct 16 12:06:42 2001
flags = nodata, delayed
old:
ctime = Mon Oct 16 11:56:51 2001
mtime = Mon Oct 16 11:56:51 2001
flags = none
older:
ctime = Mon Oct 16 11:56:46 2001
mtime = Mon Oct 16 11:56:46 2001
flags = none
oldest:
ctime = Mon Oct 16 11:56:41 2001
mtime = Mon Oct 16 11:56:41 2001
flags = non
Step 6. You can synchronously convert the “oldest” Storage Checkpoint to a nodata Storage Checkpoint
because it is the oldest Storage Checkpoint in the file system:
# fsckptadm -s set nodata oldest /mnt0
# fsckptadm list /mnt0
/mnt0
latest:
ctime =Mon Oct 16 12:06:42 2001
mtime =Mon Oct 16 12:06:42 2001
flags =nodata, delayed
old:
ctime =Mon Oct 16 11:56:51 2001
mtime =Mon Oct 16 11:56:51 2001
flags =none
older:
ctime =Mon Oct 16 11:56:46 2001
mtime =Mon Oct 16 11:56:46 2001
flags =none
oldest:
ctime =Mon Oct 16 11:56:41 2001
mtime =Mon Oct 16 11:56:41 2001
flags =nodata
Step 7. Remove the “older” and “old” Storage Checkpoints. After you remove the “old” Storage Checkpoint,
the “latest” Storage Checkpoint is automatically converted to a nodata Storage Checkpoint because
the only remaining older Storage Checkpoint (“oldest”) is already a nodata Storage Checkpoint:
# fsckptadm remove older /mnt0
# fsckptadm remove old /mnt0
# fsckptadm list /mnt0
/mnt0
latest:
ctime =Mon Oct 16 12:06:42 2001
mtime =Mon Oct 16 12:06:42 2001
flags =nodata
oldest:
ctime =Mon Oct 16 11:56:41 2001
mtime =Mon Oct 16 11:56:41 2001
flags =nodata
