Hello, lists. I have a 108 OSD ceph cluster. All OSDs work fine except one OSD-86. ceph-osd@86.service stopped working at a random time. The disk is normal by checking with `smarctl -a`. It could be fine for a few days after I restart it. Then it goes wrong again. I paste the related log here. It stopped at 05:26 UTC. --- 2023-02-17T05:26:37.795+0000 7ff525846700 0 log_channel(cluster) log [DBG] : 17.df scrub starts 2023-02-17T05:26:37.799+0000 7ff525846700 0 log_channel(cluster) log [DBG]
