I still tried "lazy umount" (-l option), it didn't help:

Unmount Command = "/bin/umount -l %m"

I also tried running SD as root, no success either.

I found a couple of similar posts from the last few months, and an old bug
report #830 that was closed in July 2007 as "fixed". Looks like some old
problem is back?


Btw, OS version above was a typo, this is up-to-date CentOS 5.3
