Hello,

I am trying to sort out why a few of my filesystems are not mounting upon a reboot.


EDIT*** Sorry forgot to add OS Info AIX 5.3 5300-06

If you have any ideas please let me know.

I appreciate any assistance you can offer to resolve this matter.
When I reboot I see the following filesystems mounted
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 1048576 958904 9% 2602 1% /
/dev/hd2 4325376 2852700 35% 36166 4% /usr
/dev/hd9var 786432 621004 22% 449 1% /var
/dev/hd3 786432 453124 43% 66 1% /tmp
Missing are the following
/dev/hd1 5242880 3026180 43% 12704 1% /home
/dev/hd10opt 2097152 1909792 9% 1533 1% /opt
/proc - - - - - /proc

After rebooting, I can issue a mount -a and all filesystems appear to be mounted.

Here is a copy of my /etc/filesystems

Is there any error message?

Try to use fsck on those filesystems.

Looks like a problem in /etc/rc, the mount all command is not running.

It is recommended to use jfs2 for all file systems.
check boot log by:
alog -o -t boot

jfs 2 is not a good idea if you might be booting with a 32 bit kernel such as a nim install.

Hi everyone,

Thanks for the information, and suggestions.

While reviewing the logs I found that a previous admin had removed the /etc/rc script.

I will add the rc script back to /etc/ and remove my workaround
The workaround I came up with prior to knowing this was to create a mountall script that gets executed upon start up. ( I did not like this resolution as it is not standard.)

I just wanted to thank you all for your time and assistance.
