AIX - JFS Recovering a deleted file ( undelete )

Unix, Work 5 Comments »

This is a document I wrote a while back for work that I thought I would release in hopes that some people out there would find it useful.

Preferably, you have a backup of the file system that you can use. If not, the filesystem you are about to try to to recover a file on must meet these requirements:

  • No new files have been created on the filesystem.
  • No files have been extended.
  • The filesystem is able to be unmounted.
  • It is a JFS filesystem, not JFS2

If so, then please, drink a few more beers and continue, but before you do…

BACKUP THE CURRENT FILESYSTEM!
