Suggestion to PPCC.
Hello,
PPCC v1.4.9
"chk_filesystem: Unless LVM is used to manage /, /usr, /var and /opt, only /usr may be mounted on a separate partition."
RHEL 6 Documentation -> 9.15.5. Recommended Partitioning Scheme (https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s2-diskpartrecommend-x86.html)
"
Do not place /usr on a separate file system
If /usr is on a separate file system from /, the boot process becomes much more complex because /usr contains boot-critical components. In some situations (like installations on iSCSI drives), the boot process might not work at all.
"
The suggestion is: delete "only /usr may be mounted on a separate partition"
Does anyone agree with that?

Red Hat's statement is correct and does not conflict what what EMC says. We support users who break out /usr, although we do not recommend it, as some customers need to have a separate /usr filesystem for internal reasons. However, we do not support separate /var or /opt filesystems unless LVM is in use. So the bottom line is that IF you are going to break something out without LVM, only /usr is a candidate when PowerPath is in use, but nothing here says that you _should_ do so.
Personally, I'd recommend putting it all under LVM anyway, and so does Red Hat. That's how their default install works.
