Hey Guys,
I am currently having a strange problem. I have a system with 4
onboard sata ports. The system also has four 4-port sata controllers
plugged into it.
The raid works fine but if i reboot the system, sometimes my harddisks
are mixed up so that my system disk(normally sda) is sometimes sdb or
sdc... My system disk is plugged to one of onboard sata ports.
I already tried to bind the disks statically via udev to a certain
device name, but no chance.
Are there any other methods to stop this mixing of the drives? Or does
anyone have the same problem?
I was really hoping one of the hardware guys would answer this. My only
thought is that you have a feature enabled which allows simultaneous
discovery, and that the 1st drive spun up is sda,, etc. If you could
save your dmesg from a good and bad boot, and make them available,
someone may see the problem, I can't guess beyond what I've said already.
If you are building the arrays using UUID in the config file, it should
matter what they are called, of course. Mine just list devices
PARTITIONS and then a bunch of arrays based on UUID. It makes for a huge
dmesg file, of course, filled meaningless babble about "found this" and
"that doesn't match." But it works every blessed time, which is more
important in the long run.
