Dell PowerEdge Systems Red Hat Enterprise Linux 8 Release Notes
/proc/mdstat and mdadm -D commands display incorrect statuses when two NVMe devices are surprise removed from a RAID 5 MD array
- Description
- When two of three NVMe devices are surprise removed from a RAID 5 MD array, the command cat/ proc/mdstat displays the array status incorrectly as active. Similarly, when the status of the MD RAID is queried using the mdadm -D /dev/mdN command, the number of active and working devices that are displayed is two. Only the status of the array reported is incorrect. However, when I/O operations are performed, I/O errors are observed as expected.
- Cause
- When the number of devices that are surprise removed exceeds the number of devices that are required for the array to function, the MD status is not updated.
- Systems affected
- All Dell EMC PowerEdge systems supporting NVMe Surprise Removal.
- Applies to
- Red Hat Enterprise Linux 8.2 and later
- Tracking number
- 182820
