File system creation time

To determine the time and date a file system was created, you can use the getlvcb command. First, figure out what the logical volume is that is used for a partical file system, for example, if you want to know for the /opt file system:

# lsfs /opt
Name         Nodename Mount Pt VFS   Size    Options Auto Accounting
/dev/hd10opt --       /opt     jfs2  4194304 --      yes  no
So file system /opt is located on logical volume hd10opt. Then run the getlvcb command:
# getlvcb -AT hd10opt
  intrapolicy = c
  copies = 2
  interpolicy = m
  lvid = 00f69a1100004c000000012f9dca819a.9
  lvname = hd10opt
  label = /opt
  machine id = 69A114C00
  number lps = 8
  relocatable = y
  strict = y
  stripe width = 0
  stripe size in exponent = 0
  type = jfs2
  upperbound = 32
  fs = vfs=jfs2:log=/dev/hd8:vol=/opt:free=false:quota=no
  time created  = Thu Apr 28 20:26:36 2011
  time modified = Thu Apr 28 20:40:38 2011
You can clearly see the "time created" for this file system in the example above.

UNIX Health Check delivers software to scan Linux and AIX systems for potential issues. Run our software on your system, and receive a report in just a few minutes. UNIX Health Check is an automated check list. It will report on perfomance, capacity, stability and security issues. It will alert on configurations that can be improved per best practices, or items that should be improved per audit guidelines. A report will be generated in the format you wish, and the report includes the issues discovered and information on how to solve the issues as well.
