I have a problem with an AIX server what I manage. I had some filesystem created to store the structure of an Oracle instance. But after the weekend scheduled reboot the filesystems are unmounted when we arrive on monday morning.

The unmounted filesystems appears in the /etc/filesystem file. There are two of the filesystems. Extracted from /etc/filesystem file

/appli2/oracle/DATA/oradata05:
        dev             = /dev/lvoradata05HIST
        vfs             = jfs2
        log             = /dev/loglv01
        mount           = false
        account         = false

/appli2/oracle/DATA/oraarch:
        dev             = /dev/lvoraarchHISTO
        vfs             = jfs2
        log             = /dev/loglv01
        mount           = false
        account         = false

Any idea why the filesystem gets unmounted after weekend reboot?

We use AIX 6 as operating system.

Your /etc/filesystemssays for both filesystem mount = false.

So, edit your system /etc/filesystems to have:

/appli2/oracle/DATA/oradata05:
        dev             = /dev/lvoradata05HIST
        vfs             = jfs2
        log             = /dev/loglv01
        mount           = true
        account         = false

/appli2/oracle/DATA/oraarch:
        dev             = /dev/lvoraarchHISTO
        vfs             = jfs2
        log             = /dev/loglv01
        mount           = true
        account         = false

  • There is a command to modify this values or i need to use vi or other editor to modify the value ? Commented Mar 20, 2014 at 18:00

    AIX way of doing things is through the smit tool (or its non-graphical equivalent smitty), but vi is fine with me. I added some info about AIX administration.

  • You could also use the chfs command. chfs -A yes /appli2/oracle/DATA/oradata05 Commented Apr 3, 2014 at 12:07
