The hooks thing you're thinking of is the DMAPI standard. I think it's only supported in a subset of filesystems, things like xfs, jfs, GPFS, etc. I don't know if there are any free HSMs that use it out there. Googling turned up a CERN HSM project, CASTOR. It isn't a transparent interface, but that avoids a lot of OS hassle. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
