Conversion with Multiple Storage Checkpoints
The following example highlights the conversion of data Storage Checkpoints to nodata
Storage Checkpoints, particularly when dealing with older Storage Checkpoints on the same
file system:
To convert Storage Checkpoints :
1. Create a file system and mount it on /mnt0:
# mkfs -F vxfs /dev/vx/rdsk/dg1/test0
version 6 layout
1024000 sectors, 512000 blocks of size 1024, log size 1024 blocks
largefiles supported
# mount -F vxfs /dev/vx/dsk/dg1/test0 /mnt0
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
