[Ocfs-users] OCFS disk failure problem.

[Chris Steinke]

Hi Wim, 

Thank you for the quick reply!

I am using a HP/Compaq Smart Array Cluster Storage (SCSI LVD Attached)

I had put the export file on the shared array...

<light bulb goes on> 

Think this would be the problem? :-)


Did you help me answer my own question? 


Thanks!

Chris
