Hi:
I have two questions I'm hoping some kind soul can help me with today.
First, where can I find information on setting up fibre channel served storage on linux ? Is there a howto anywhere ? I've just spent a fruitless 1/2 hour googling, only to turn up a number of trade mag articles. In particular, I'd like to know how to deal with multi-path setups, and the more entry level the documentation, the better. :-/
(in other words, there are many people here who understand SANs, but I am not yet one of them)
Second, I'm curious how close to the following setup I can come today:
~ +-- FC Cabinet 1 --+ +-- FC Cabinet 2 --+ ~ | some disk | | some disk | ~ +------------------+ +------------------+ ~ | | \ / ~ SAN FABRIC / \ ~ | | ~ +-- linux box 1 -|-+ +-| linux box N ---+ ~ | | | | | | ~ | +-------|--cluster sw--|------+ | ~ | | mirror FC1 & FC2 | | ~ | | cluster LVM | | ~ | | cluster fs | | ~ | +-----/------------------\----+ | ~ | / | | \ | ~ | user visible fs | | user visible fs | ~ +------------------+ +------------------+
In essense, I wish to have storage across two cabinets, mirrored, sliced up via a LVM, then served as a cluster filesystem to N linux hosts, without a single point of failure.
Is the above possible ? If not, which peices can I not do today ? How soon might I be able to do them ?
(Please note that in particular the mirroring need not be done in the linux boxes, if there's a way to mirror across cabinets in different data centers in some other manner)
Thanks, - -- Pat -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org
