Do you know if there was a previous version of GRUB 2 where this worked? For example, how does the version in testing behave? (This is for practical reasons: if this has just always been broken in GRUB 2, then it shouldn't block migration of 2.02~beta2 to testing.) > I initially was running an 8-disk RAID 6 mdadm.

OK, so that implies that this doesn't have much directly to do with RAID handling: the problem is probably simply that GRUB can't see all 14 disks. > I've tested using VMWare and confirmed that 8-disk RAID 6 mdadm arrays > work fine with grub for root, but 9 disk and above break the system > and drop to rescue shell. A quick test in qemu shows that GRUB can see more than eight disks there. Could you please share details of your VMware setup so that I might stand a chance of reproducing this?
