I have a RAID6 array which was created on a Supermicro card built around the LSI 2108. Two drives failed, I replaced one and started a rebuild, then two more failed, making my array go offline. It looks like the failure was due to a cabling or backplane problem, and I suspect the data on the drives is good. However, the Supermicro card is unable to read the foreign configs (it thinks there are 3 foreign configs, none of which are importable into a working array). I would like to attempt recovery per the Wiki’s instructions (overlay files, force assembly, etc); can md read a RAID6 created by the 2108, or would I be wasting my time? I have moved the drives from the hardware RAID card to a non-RAID SAS card and can see all drives. However, mdadm -E on these drives seems to show the RAID controller’s field of vision (how many defined arrays, total number of physical disks in the system), not any insight into this drive’s role as a member of an array. I can paste or gist the output of madam -E (304 lines) if it would help.
