Ok, so I got RHEL 5.5 installed on a VM in VMware Workstation 6.5. I installed Oracle Grid Infrastructure, setup my ACFS disk groups, install Oracle Database 11g Release 2 11.2.0.0.0 software and then created my database.
I was able to login and use Enterprise Manager. I decided to do a restart of my system and now when I log back in all the first from my software location directory are gone. This has happened to me twice now. The directories are all still there, the grid files are there, it is just the software files that are missing (ORACLE_BASE location).
I created an ACFS for database home on my ACFS disk group, which has a mount point of /u01/app/oracle/acfsmounts/acfs_db1. This is the directory where the files have been removed from.
anyone know why this is happening?

Congratulations on getting so far with 11.2, not many people try to use ACFS. Possibly because of what you have discovered.
If you are using ACFS for your Oracle home, there are two common problems.
First, is the volume enabled? Does the device driver in /dev/asm actually exist, can you see it with ls? If not, create it by enabling (or re-enabling) the volume, the easiest way is the volenable command in asmcmd.
Second, if the volume is enabled, is the file system mounted? If not, mount it with a standard mount command, such as
mount -t acfs /dev/asm/vol1 /u01/whatever

I have that in my scripts already, it doesn't work to mount the ASM Cluster file system.
I tried adding this command to the same file:
/sbin/mount.acfs -o all
but that didn't work either, the ASM Cluster File system still didn't get mounted on a reboot.
I am going to create another file with this command and see if that works.

The problem with using /etc/fstab is that it is processed before starting the Clusterware.
Overall, I see little point in using ACFS for your Oracle home. One reason I can see is if you using server pools. In that case, you would want to mount the appropriate Oracle home on every node that is currently running an RDBMS instance. It is (I think) theoretically possible to build in a dependency, such that the file system will be mounted by the Clusterware on whatever nodes the Clusterware decides to start an instance, and on no others. But I have no customers who are considering using server pools.
Does that reason make sense? And can anyone see any other reason for putting your $OH on ACFS?
