目前通过麦沃硬盘盒装载了一个硬盘连接到unraid中，但三天两头会出现磁盘告警 read error，unraid重新启动后又恢复正常。 根据日志分析发现，出现告警显示 usb disconnect May 18 16:44:38 Tower kernel: usb 2-2: USB disconnect, device number 2 May 18 16:44:38 Tower kernel: sd 1:0:0:0: [sdb] Synchronizing SCSI cache May 18 16:44:38 Tower kernel: sd 1:0:0:0: [sdb] Synchronize Cache(10) failed: Result: hostbyte=0x01 driverbyte=DRIVER_OK May 18 16:44:40 Tower kernel: md: disk1 write error, sector=1973964792 May 18 16:44:40 Tower kernel: md: disk1 write error, sector=1973964800 May 18 16:44:40 Tower kernel: md: disk1 write error, sector=1973964808 自动重新连接上后，显示磁盘路径由 /dev/sdb -> /dev/sdc May 18 16:44:48 Tower kernel: usb 2-2: new SuperSpeed USB device number 4 using xhci_hcd May 18 16:44:48 Tower kernel: usb-storage 2-2:1.0: USB Mass Storage device detected May 18 16:44:48 Tower kernel: usb-storage 2-2:1.0: Quirks match for vid 152d pid 0578: 1000000 May 18 16:44:48 Tower kernel: scsi host4: usb-storage 2-2:1.0 May 18 16:44:49 Tower kernel: scsi 4:0:0:0: Direct-Access ST4000VX 015-3CU104 0601 PQ: 0 ANSI: 6 May 18 16:44:49 Tower kernel: sd 4:0:0:0: Attached scsi generic sg1 type 0 May 18 16:44:49 Tower kernel: sd 4:0:0:0: [sdc] Very big device.
