Veritas™ File System 5.0.1 Administrator's Guide

For disk layout Version 6 or 7, multiply the number of inodes by 1 byte, and add
1 or 2 megabytes to get the approximate amount of space required. You can
determine the number of inodes with the fsckptadm utility as above. Using the
output from the example for disk layout Version 5, the approximate amount of
space required by the metadata is just over one or two megabytes (23,872 x 1 byte,
plus 1 or 2 megabytes).
Use the fsvoladm command to determine if the volume set has enough free space.
See the fsvoladm(1M) manual page.

Creating a Storage Checkpoint
The following example shows the creation of a nodata Storage Checkpoint named
thu_7pm on /mnt0 and lists all Storage Checkpoints of the /mnt0 file system:
# fsckptadm -n create thu_7pm /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
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
