Fwd: RAID6 Array crash during reshape.....now will not re-assemble.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Kernel is latest Fedora x86_64 4.3.5-300, can't get too much newer
then that (latest is 4.4.x), mdadm is 3.3.4-2.

I agree that the data is likely still intact, doesn't stop me being
nervous till I see it though!!
