Hi, I just got a new SATA controller and moved some of my drives around, so the device numbers of course got all messed up. I expected mdadm to be able to handle that, which it did when I moved one device. However, when I moved the next 3, things got weird. Here's the output from mdadm --assemble --scan -v: ... <removed unmatching devices> mdadm: /dev/sdj1 is identified as a member of /dev/md5, slot 3. mdadm: /dev/sdi1 is identified as a member of /dev/md5, slot 2. mdadm: /dev/sdh1 is identified as a member of /dev/md5, slot 1. mdadm: /dev/sdg1 is identified as a member of /dev/md5, slot 0. mdadm: /dev/sdf1 is identified as a member of /dev/md5, slot 6. mdadm: /dev/sde1 is identified as a member of /dev/md5, slot 7. mdadm: /dev/sdd1 is identified as a member of /dev/md5, slot 9. mdadm: /dev/sdc1 is identified as a member of /dev/md5, slot 8. mdadm: /dev/sdb1 is identified as a member of /dev/md5, slot 5. mdadm: /dev/sda1 is identified as a member of /dev/md5, slot 4. mdadm: added /dev/sdh1 to /dev/md5 as 1 mdadm: added /dev/sdi1 to /dev/md5 as 2 mdadm: added /dev/sdj1 to /dev/md5 as 3 mdadm: added /dev/sda1 to /dev/md5 as 4 mdadm: added /dev/sdb1 to /dev/md5 as 5 mdadm: added /dev/sdf1 to /dev/md5 as 6 mdadm: added /dev/sde1 to /dev/md5 as 7 mdadm: added /dev/sdc1 to /dev/md5 as 8 mdadm: added /dev/sdd1 to /dev/md5 as 9 mdadm: added /dev/sdg1 to /dev/md5 as 0 mdadm: /dev/md5 assembled from 7 drives - not enough to start the array. The added drives are the correct ones, but how it adds 10 drives but then thinks that it's only assembled 7 mystifies me. Is this a bug?
