I think you have to abandon the "network RAID" idea. You may be referring to SAN storage, in which case RAID is unnecessary. You could use RAID 1 for mirroring your data disk, or RAID 5 to combine multiple disks into one file space, with a hot spare - very reliable and redundant.. But that is on a machine basis, not a group of machines.
Yeah, i'm aware of normal RAID usage and i've seen a basic RAID 5 done with ENBD but i have no idea how reliable it was and i'd hate to set things up like that.
If you were to use RO volumes for EVERY volume on your system, you would have a administator nightmare. It is recommended that only infrequently changed volumes be replicated. Each time you change the volume data, you would need to 'vos release' that change to the RO volume(s).
Right, so if I was to set up AFS on a single server, how could I safely replicate this to other machines? I think i'm probably getting confused but i'd appreciate some sort of clarification. I don't expect it to failover flawlessly, but i do require the ability to rapidly bring up another machine to replace the primary. Apologies if I haven't explained properly, Paul _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
