I'm using chef to create RAID10 arrays.
Last friday morning (10/22) I was able to create arrays with 9 EBS volumes on dev/sdz1-9 with no problems
I started having trouble attaching more than 6 EBS volumes on friday night. I put it down to EC2 problems (maybe overload) and stopped work for the weekend.
This morning the problem continues. Volumes 1-6 attach fine (e.g /dev/sdx1-6). Anything after that on the same dev major device stays in the "attaching" state forever.
I can then use /dev/sdv1-6 no problems but again, no more than 6 on that major device.
Anyone else notice behaviour like this? Am I missing something?
