Dear all,
I find the raidtools-1 (comes with Redhat 7.3) doesn't allow you to run raid 0+1. Here is the problem .
I have 2 raid 0 devices /dev/md2 /dev/md3 and then I run raid 1 ontop of these raid 0 devices (/dev/md4).
The md2 and md3 sucessfully started, but when come to md4 raidstart always return "invalid argument" . The point is that the partition has already initialised, but if you run "raidstop /dev/md4" and then it cannot start again. If you run "'mkraid /dev/md4" it will initialise the raid and start automatically, that means there are some problems that the "raidstart" command does not allow raidstart on md devices but the mkraid allows you to do that. If anyone have experience please comment and advice. Thanks.
regards, David
