A disk failed in one node of my cluster. I can see the /opt/mapr/logs/faileddisk.log file several days ago. But now it seems that the log file disappeared. Just see a zero size file named disk_by-path_pci-0000:02:00.0-scsi-0:2:6:0.failed.info under the logs directory. Where can i find the faileddisk.log file or the failed reason in the log file now? Thanks.
