Re: Renumbered MD arrays causes EVMS to fail

Well I've finally solved my problem by doing the following :



* disconnected all my sata disks, to force my raid1 array to be recognized first as md0

* removed one disk from my raid1 array

* reformatted the disk to remove the fd partition

* copied all data from the degraded raid to this "new" disk

* tried installing grub on the new disk but had trouble doing it from a live system, so finally did it from a knoppix bootdisk

* through evms deleted my raid0 array and all volumes resting on it

* reconnected my sata disks which now are recognized as md0



Now everything works fine, although I've lost my raid1 array ;-(



but I could always rebuild it if I wasn't afraid of facing the same problems at some later time....

Subject: Renumbered MD arrays causes EVMS to fail



Hi,I've upgraded my kernel to 2.6.17 from 2.6.9 and my raid arrays are now numbered differently than before causing evms to fail.Previously :md0 : raid1 with hda hdcmd1 : raid5 with sda sdb sdc sddnow my sata disks are picked up first as md0, while the IDE disks become md1. My problem is that my raid5 array has an LVM2 volume above it, which can't be recreated anymore.How can I either change the sequence in which they are identified or update EVMS to take into account the change ?_______________________________________________Join Excite! - http://www.excite.comThe most personalized portal on the Web!
