      There was an outage on our site where a script was deleting tons of valuable data from Lustre file systems. It takes some times to figure out the problematic script and kill it.

      It seems like Lustre lacks of a functionality to set the whole file system into readonly mode, which is useful in this case because it can help stop bleeding immediately.
