Issue

  • RAID reconstruction never starts after disk failure with available spare disk or after failed disk replacement.
  • Replaced disk model and character is similar to the failed disk.
  • Replaced disk may show different type or RPM value from the original disk, example:

RAID group /aggr0/plex0/rg1 (degraded, block checksums)
