Really - which linux does this? I've built numerous servers with 24 SSDs and on the servers with no raid controllers, the disks are always enumerated in the order of what sata controller port they are plugged into for RH, Cent and Debian variants.

It's something to add to my bag of tricks. Still, this punctuates the point. Why do we need so many workarounds? Because the kernel's behavior is stupid. > For the disks - > especially when you have hardware raid and you want the disks in a > specific order - you have to load the driver modules in the order you > want the disks seen. This only works if you have different RAID controllers. If you have identical controllers or many disks on a single JBOD interface then there is no way to control the enumeration order. You have to fall back on hacks like volume labels and UUIDs. -- Rich P. _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
