i have a nested file system.
This scenario:
2 nodes of cluster.
/pippo in the /etc/fstab of 2 nodes
/pippo/connect in the Service Guard package.
I need to know if this nested file system is a problem.
Is this a bad configuration? what kind of problem may have?
Solved! Go to Solution.

Re: File system nested
For me is not a problem because when the package on SG start, the vg is activated, the fs is mounted on /pippo/connect, when you stop the package you umount /pippo/connect.
The only problem is you can't umount /pippo when the package is started.

Re: File system nested
Nested FS is not an issue.
The mount should actually be done however in the package control script.

Re: File system nested
but i have a /pippo that is local on all nodes, and cannot put into ServiceGuard Package.
Are there known issues or not ?

Re: File system nested
we need to know the structure of your volumes.
SG relies an the underlying lvm
Thus
Is /pippo part of /vg00 (thus local)
and /pippo/connect of /vg01 (enabled by package)
Then it is not issue.

SolutionlocalFS
clusterpkgFS
then
/localFS1/clusterpkgFS1 is supported
/localFS1/localFS2/clusterpkgFS1 is supported
/localFS1/clusterpkgFS1/clusterpkgFS2 is supported - but be careful with the ordering in the package and don't set any concurrent mount/umount operations
/clusterpkgFS1/localFS1 is *NOT* supported
Does that help make it clear?
