Hi,
what is the best/recommended way to do remote swapping via the network
for diskless workstations or compute nodes in clusters in Linux 2.4?
Last time i checked was linux 2.2, and there were some races related
to network swapping back then. Has this been fixed for 2.4?
What about the following options: Do they work at all? What are the advantages/
disadvantages? What are the performance implications? Race conditions?
1. Swapping via NFS? There was a patch for this for 2.2? Is there such a
patch for 2.4 as well? Should one use UDP or TCP? NFSv2? NFSv3?
2. Using some sort of network block device (nbd, new nbd, gnbd, drbd,
possibly others?). Which one to use? I suspect that for performance
a kernel mode implementation is needed for both client and server.
3. iSCSI. There are several implementations, and I don't know if any of
these is ready for production use. Both initiator and target
implementation would be needed because I don't have any native iSCSI
targets available.
4. Swapping to GFS? Is that possible? Even if GFS is based on gnbd, not FC?
5. Anything else? Maybe some implementation of network memory in the context
of a cluster computing environment (MOSIX, etc.).
Thanks for any answers.
Cheers,
Dirk
