This error requires to optimize the filesystem, if you already did so, but still get this error, seems your disk subsystem just slow. You may increase a timeout for this check to do not crash your node, with a some drawbacks, of course:
You could increase it by 30s seconds until the node would not stop to crash.
However, if you would be forced to increase it more than 5m0s (by the way, please check, what exact check it’s failed - the writeable or a readable?), then you likely have a bigger problem with this disk, maybe it’s dying. And also you would need to increase a writeable check interval too (it’s 5m0s by default).
