Causes:
A failure occurred in data drives greater than the parity group
redundancy. The redundancy of the parity group depends on the
number of the blocked PDEVs (data drives). For example:
◦
When the parity group configuration is 3D+1P and failures occur
in two or more drives, the failures are considered to have occurred
in data drives beyond the parity group redundancy.
◦
When the parity group configuration is 6D+2P and failures occur
in three or more drives, the failures are considered to have
occurred in data drives beyond the parity group redundancy.
