Dear *, I have started to build a HA system. It runs a postgresql cluster with two nodes (master and hot stand-by, FreeBSD 9.0, postgresl 9.1). The storage for the database is provided by 2 separate systems (FreeBSD 9.0, iSCSI target, over ZFS). For the maximum redundancy I would like to use multipathing on the DB nodes. For me the best would be if the 2 DB nodes and the 2 storage nodes are all FreeBSD. Now I have 4 installed FreeBSD 9.0, iSCSI targets are in place, and the database nodes uses the exported targets as a storage. What is left is the multipath part. I have search a lot in this topic, but now I am really confused. I found some mails from this mailing list, the problem was the same, and there was no solution, but the mails are quite old (FreeBSD 7.3). I checked gmultipath, but it seems it is not the solution. Does FreeBSD support iSCSI multipath currently, or should I change the OS under the database nodes from FreeBSD to some linux distribution. I found a lot of working configuration for linux and iSCSI multipathing. Cheers, Matyee
