But the kernel does not (yet) generate udev events when md arrays are added or removed. > That seems sane, not twisting at all, to me. Last I checked this > is also the way LVM works. Will lvm2 be getting a similar "fix"? lvm2 is in much the same boat. Take mdadm --assemble --auto=yes /dev/md0 /dev/sd[abc]1 This creates the /dev/md0 device node and then uses ioctl()'s to assemble the array behind it, using the components in the first partition of the drives. A more natural way would be to tell the kernel to assemble the components via /sys, and then, once the device is ready, give it a name (which could come from persistent data in the superblock), and have something create the appropriate node under /dev. But as said, mdadm will likely grow the second capability in addition, not instead of the first. -- .''`. martin f. krafft <madduck@debian.org> : :' : proud Debian developer, author, administrator, and user `. `'` http://people.debian.org/~madduck - http://debiansystem.info `- Debian - when you have better things to do than fixing systems because light travels faster than sound, some people appear to be intelligent, until you hear them speak.
