I haven't heard of anything similar. You might try enabling full Lustre debugging ("lctl set_param debug=-1" on both the client and MDS) running strace on your commands to see where the error is generated. Then dump the Lustre debug log with "lctl dk /tmp/debug" on the client/MDS and look for "-2" (=-EPERM) error returns.

System; although no similar problems appear mounting other types of file systems (we have many others). So the problem appears to be
Specific to the lustre mounts. Users with the large UIDs get “permission denied” if they try to access the file system, and commands like ls(1)
Show question marks for most fields (permission, owner, group, …). Is there a non-default mount option required to use lustre with large UID
