Re: [Linux-cluster] umount failing...




selinux is in Enforced mode ( worth checking audit.log ) ? .If yes, try selinux to permissive or disabled mode and check .

My appologies for not getting back sooner. I am in the middle of a move.

I cannot post my configs or logs (yeah, not helpful I know) but
suffice it to say I strongly believe they are correct (I know,
everyone says that). I've had other people look at them just make sure
it wasn't a case of proofreading my own paper etc. and it always comes
down to the umount failing. I have 6 other identical NFS services
(save for the mount point/export location) and they all work
flawlessly. That's why I am zeroing in on the use of '/home' as the
culprit.

Anyway, it's not a lot to go on I know, but I am just looking for
directions to search for now.

Thanks
