-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Everyone,
We've been using an MD1000 as our storage array for close to a year now, just hooked up to one OSS (LVM+ldiskfs). I recently ordered 2 more servers, one to be hooked up to the MD1000 to help distribute the load, the other to act as a lustre client (web node). The hosting company informs me that the MD1000 was never setup to operate in split mode (which I asked for in the beginning) so basically only one server can be connected to it. I now am faced with a tough call, we can't bring the filesystem down for any extended period of time (a few minutes is OK, though 0 downtime would be perfect!) and I'm not sure how to proceed in a way that would make things cause the least amount of headache. The only thing I can think of is to set up a second MD1000 (configured for split mode) connect it to OSS2 (the new one which is not yet being used), add it to the Lustre filesystem and then somehow migrate the data from OSS1 (old MD1000) to OSS2 (new MD1000) ... then, bring OSS1 offline, and connect it to the second partition of new MD1000 and bring that end online once more. I've never done anything like this and am not entirely sure if this is the best method. Any suggestions, alternatives, docs or things to look out for would be greatly appreciated.
