Doc Text: |
Using *mdadm* to assign a hot spare to a degraded array while running I/O operations no longer fails
Previously, assigning a hot spare to a degraded array while running I/O operations on the MD Array could fail, and the *mdadm* utility returned error messages such as:
mdadm: /dev/md1 has failed so using --add cannot work and might destroy
mdadm: data on /dev/sdd1. You should stop the array and re-assemble it
A patch has been applied to fix this bug, and adding a hot spare to a degraded array now completes as expected in the described situation.
