Subject: [PATCH 46/83] tests/00readonly: Run udevadm settle before setting ro
|
|
|
|
In some recent kernel versions, 00readonly fails with:
|
|
|
|
mdadm: failed to set readonly for /dev/md0: Device or resource busy
|
|
ERROR: array is not read-only!
|
|
|
|
This was traced down to a race condition with udev holding a reference
|
|
to the block device at the same time as trying to set it read only.
|
|
|
|
To fix this, call udevadm settle before setting the array read only.
