Hi Patrick, Thanks for the instructions. We started the MDS recovery scan with below cmds following the link below. The first bit of scan extens has finished and we're waiting on scan inodes. Probably we shouldn't interrupt the process. Once this procedure failed, I'll follow your steps and let you know. Appreciate your help.
