On the clients run:
lctl dl # list lustre device configuration
lctl --device {failed OST device number} deactivate
Same on the MDS, though the device will be different compared to clients.
This will deactivate the failed OST on the clients so they get an IO error
when accessing any files on the OST, instead of waiting for it to recover.
