I think at some point during a systems administrators life span, they see the below error message when trying to mount a filesystem.
# mount /test Replaying log for /dev/fslv01. mount: /dev/fslv01 on /test: Unformatted or incompatible media The superblock on /dev/fslv01 is dirty. Run a full fsck to fix. |
If you haven’t clued on by now, AIX is my operating system of choice. I’m sure there are many arguments for and against, but looking at it from a systems administrator view point, it’s second to none. Anyway, that’s a story for another time. What I’m writing about today is patching your AIX installations using multibos. Now before I get started, I’ll stress two points:
1) Chris Gibson has already written two great (and far more in depth) articles on multibos, which I recommend reading before going any further (Links: here and here).
2) This blog of mine serves two purposes; To share some of the things I come about during my sysadmin activities and secondly also a dumping ground for documents I write for myself. This post is the latter, as multibos isn’t something that I use daily (maybe a few times a year), and really, who’s going to remember all those syntax switches 😛
Now, assuming you’ve read both articles, I don’t need to go into the benefits of multibos and I’ll dive straight into the how. I’ll be working on upgrading an AIX instance running 6100-05-01-1016 to the latest ML which at the time of writing is 6100-06-04-1112

I updated this script a while back and made it a lot easier to maintain. It now checks for usage on all mounted filesystems, except for those listed in the $SKIPFS variable.
