dynamic resize of LUNs

[Holder, Bill]

Hi all,
 
    I'm hoping someone might be able to help me get this to work
properly...
 
    Linux server with Qlogic HBA cards, has a 50gig LUN presented to it,
with a single ext3 filesystem.
 
    SAN admin has added another 50 gig to the LUN, and the server sees a
100 gig LUN.
 
    Problem is, the filesystem is now corrupt.
 
    I've tried rebuilding the devices and letting kpartx do it's thing,
but the existing filesystem always dies.
 
 
    Anyone know a good way to get this working, or am I screwed?
 
Thanks guys.
