Anyone know how to get the RAID5 working? The 8.10 version operated fine. Mdadm.conf is configured to automatically assemble the array. Nevertheless, on reboot, the Ubuntu 9.10 leaves the array 'inactive'. I believe that the stumbling block is that I've configured the array to use an external write-extent bitmap.
My current workaround is doing a
mdadm -As
followed by
sudo mdadm -G /dev/md2 --bitmap=/tmp1/md2bitmap --force
where /tmp1 is external to the RAID array. I currently have the equivalent setup in the mdadm.conf. Mdadm.conf does scuceed in assembling two RAID1 arrays.
Two questions:
- Is there a workaround for setting this up in mdadm.conf?
- Is there a way to automatically run a script on reboot to perform: the 1) assembly step (above) and 2) the forced bitmap designation?
