Yes, but DRBD only allows a two points mirroring (as far I know it). With A
3-4 computers cluster, this is not the best solution ...
Shared SCSI could be a good idea, but there are few systems wich would allow
more two connections. And the price is not the same ;-(( Will be the best
solution for systems with lots of write operations
The best thing in CODA is it allows more than one computer to mount the
filesystems. I do not know about any other technology allowing this (DRBD,
NBD, ...) This should be by far one of the greatest feature of CODA (with
support for disconnected operations).
