Description

I see the following LustreErrors showing up in irregular intervals:

The object ID is not changing. It is always one of those two mentioned. This is only happening on one OST (out of 90). Filesystem seems to be fine otherwise.

The OI_scrub seems to restart every 10 seconds or so?

What is the problem and is there a cure?
