Hi guys, I'm putting together a storage server for NAS and iSCSI purposes and have some questions about EVMS please. I've got a box of Raptor 150 ADFD drives and a 3Ware 9650SE board which will provide the basic back-end storage. Now I'm looking at options for the partitioning to support the server opsys, the NAS storage pool, and the multiple iSCSI volumes. It seems that the easiest thing to do would be to just make a single massive RAID-6 volume out of the drives, expose that to EVMS, and then chop it into segments for logical drives. Assuming that's the case: I understand that EVMS will let me dynamically resize segments, but how transparent is this? I assume it will work for the storage and system root XFS partitions, and I also assume that it will not work for the iSCSI targets (since the partition and filesystem information for those will be managed by the requester, not the server). I have read some articles that talk about splitting the large RAID into hundreds of small segments and then using those for dynamic resizing. Is that really recommended, or just a neat trick? Can grub load a /boot partition off an EVMS volume without needing a lot of black magic stuff? I'm going to be using openSUSE 10.2 for this, btw. I'm guessing I'll be better off with an unmanaged partition there, and it won't really matter if I have the 3Ware card managing the RAID anyway, but I'd prefer to use a single partition management interface. Does EVMS have support for dmraid, or is that inherited from LVM? Thanks for the help guys ------------------------------------------------------------------------- Take Surveys. Earn Cash.
