Hi, >> >> So sd[ab] are two 300 GB disks, and sdc is the big storage. >> I think this is not so uncommon. In my experience this has to do with the initialization of PCIe controller cards. I assume you are using a RAID controller, right? I saw that with Areca RAID-controllers in the past as well with LSI-controller these days. I am using UUID for that purpose. Not really convenient, but safe. You probably don't have to change that as soon as it is running, so the strange UUID designators are no big issue. best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024 _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
