Flashbackup on RHEL fails with error 156
VxSF 5.1 on RHEL5. Using vxfs snapshot method works perfect if only one raw device is in the directive list. the vxcache setting is configured in the snapshot options with a 100GB cache LUN, so I know space is not the issue. 2 seperate DG's, one vol one each, one FS on each. If I only enter one at a time in the backup selections, they both rip off there no problems. We want to have them both spin off serially, or possibly using multiple streams. I've tried multiple streams using the new stream directives, but as nothing works. I don't see this as a volume set limitation as they are totally independent. And, there is NO IO on the filessytem when trying to back them up, so the cache disk can't possibly be filling. I know we did this years ago in 4.x, but I can't seem to get this working.
I'll attach the bpfis later, but I don't see the clue in there, just that the snapshot could not occur.
