This morning it bombed out, and when I brought it up again, two drives had incorrect event counts: sda1: 0.8258715 sdb1: 0.8258715 sdc1: 0.8258715 sdd1: 0.8258715 sde1: 0.8258715 sdf1: 0.8258715 sdg1: 0.8258708 sdh1: 0.8258716 sdg1 is out of date (expected), but sdh1 has received an extra event. Any attempt to restart with mdadm --assemble --force, results in an an un-startable array with an event count of 0.8258715. Can anybody advise on the correct command to use to get it started again? I'm assuming I'll need to use mdadm --create --assume-clean - but I'm not sure which drives should be included/excluded when I do this. Many thanks! Chris Allen.
