[linux-lvm] RE: linux-lvm Digest, Vol 26, Issue 18

[Stern, Rick (Serviceguard Linux)]

I'm working with another engineer on this.  He's a little unfamiliar
with 
this area but I'll try to get him to signup on the list and respond 
directly.

The script dumps a fair amount of info after a failure and so far there
is
nothing that is suspect in that data, i.e. it seems that there are no 
active mounts our anything else open.  

He will be putting a few more tests & basic debug print statements into
the 
script - including between the unmount and the deactivate.  Obviously
this 
will change some timing.  Also, I've asked him to re-try the deactivate
in 
the script after the first failure. As we have more info, we'll post it.

Thanks,
Rick
