I am unable to start my raid6 array. At first I got sda1 missing so I went ahead and re-added it and was able to start the array. Then few minutes later I got 3 failed drives. I shut down my server, checked all the sata and power cables and booted up again. The array did not start automatically so I tried to force assemble it. sudo mdadm --assemble --verbose --force /dev/md1 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1 /dev/sdj1 /dev/sdk1 /dev/sdm1 /dev/sdp1 /dev/sdq1 mdadm: looking for devices for /dev/md1 mdadm: /dev/sda1 is identified as a member of /dev/md1, slot 15. mdadm: /dev/sdb1 is identified as a member of /dev/md1, slot 8. mdadm: /dev/sdc1 is identified as a member of /dev/md1, slot 1. mdadm: /dev/sdd1 is identified as a member of /dev/md1, slot 3. mdadm: /dev/sde1 is identified as a member of /dev/md1, slot 6. mdadm: /dev/sdf1 is identified as a member of /dev/md1, slot 9. mdadm: /dev/sdg1 is identified as a member of /dev/md1, slot 10. mdadm: /dev/sdh1 is identified as a member of /dev/md1, slot 0. mdadm: /dev/sdi1 is identified as a member of /dev/md1, slot 11. mdadm: /dev/sdj1 is identified as a member of /dev/md1, slot 7. mdadm: /dev/sdk1 is identified as a member of /dev/md1, slot 5. mdadm: /dev/sdm1 is identified as a member of /dev/md1, slot 14. mdadm: /dev/sdp1 is identified as a member of /dev/md1, slot 2. mdadm: /dev/sdq1 is identified as a member of /dev/md1, slot 4. mdadm: ignoring /dev/sdq1 as it reports /dev/sda1 as failed mdadm: added /dev/sdc1 to /dev/md1 as 1 mdadm: added /dev/sdp1 to /dev/md1 as 2 mdadm: added /dev/sdd1 to /dev/md1 as 3 mdadm: no uptodate device for slot 4 of /dev/md1 mdadm: added /dev/sdk1 to /dev/md1 as 5 mdadm: added /dev/sde1 to /dev/md1 as 6 mdadm: added /dev/sdj1 to /dev/md1 as 7 mdadm: added /dev/sdb1 to /dev/md1 as 8 mdadm: added /dev/sdf1 to /dev/md1 as 9 mdadm: added /dev/sdg1 to /dev/md1 as 10 mdadm: added /dev/sdi1 to /dev/md1 as 11 mdadm: no uptodate device for slot 12 of /dev/md1 mdadm: no uptodate device for slot 13 of /dev/md1 mdadm: added /dev/sdm1 to /dev/md1 as 14 mdadm: added /dev/sda1 to /dev/md1 as 15 mdadm: added /dev/sdh1 to /dev/md1 as 0 mdadm: /dev/md1 assembled from 11 drives and 2 spares - not enough to start the array. Any ideas what could have gone wrong and how I can possibly start the array again? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
