Description
Hi
This is Manish from nasa and we were getting some hangs on ls command and because of that we started running the "lfsck" command on all OSS nodes to clear up stale entries and that crashed all the servers after a long run of lfsck command.
PID: 25536 TASK: ffff881bc2abaf70 CPU: 9 COMMAND: "lfsck"
