June 1Jun 1 Something very weird just happened.I connected an empty USB-drive (at least, it's supposed to be empty, I erased it last month) and when I came back to my PC upstairs, nothing was responding. I could ping it, but no containers were reachable, the webUI was not reachable, SSH wasn't reachable,... I could only ping its IP, but no containers custom IPs.After searching for half an hour, I gave up and power cycled the server. After booting back up, everything seemed fine.The stored syslog shows a whole lot of read errors from the moment I connected the drive. The complete file is attached.1 20:25:32 Willow kernel: usb 5-2: USB disconnect, device number 2Jun 1 20:25:33 Willow kernel: sd 6:0:0:0: [sdf] Synchronizing SCSI cacheJun 1 20:25:33 Willow kernel: sd 6:0:0:0: [sdf] Synchronize Cache(10) failed: Result: hostbyte=0x01 driverbyte=DRIVER_OKJun 1 20:25:33 Willow kernel: I/O error, dev loop0, sector 1202912 op 0x0:(READ) flags 0x800 phys_seg 8 prio class 2Jun 1 20:25:33 Willow kernel: SQUASHFS error: Failed to read block 0x24b5c56b: -5Jun 1 20:25:33 Willow kernel: SQUASHFS error: Unable to read fragment cache entry [24b5c56b]Jun 1 20:25:33 Willow kernel: SQUASHFS error: Unable to read fragment cache entry [24b5c56b]Jun 1 20:25:33 Willow kernel: SQUASHFS error: Unable to read page, block 24b5c56b, size 7b49Jun 1 20:25:33 Willow kernel: SQUASHFS error: Unable to read fragment cache entry [24b5c56b]Jun 1 20:25:33 Willow kernel: SQUASHFS error: Unable to read page, block 24b5c56b, size 7b49Jun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30688) failedJun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30689) failedJun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30690) failedJun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30691) failedJun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30692) failedJun 1 20:25:33 Willow kernel: FAT-fs (sdf1): Directory bread(block 30693) failedWhat could this be? Is that drive at fault, or did I bump something while connecting it at the back of the server?Just trying to understand what happened to avoid it in the future. As said, the server is running fine now it's rebooted with the drive disconnected.crash.txt Edited June 2Jun 2 by bartdejonckheere
June 2Jun 2 Community Expert If sdf is the flash drive, it got disconnected, or there are issues with it.
June 2Jun 2 Author Looks like that was indeed my drive, since sdf normally isn't used. But why does that bring my server down if it's just an unassigned device?
June 2Jun 2 Community Expert Solution The problem was the flash drive dropping offline11 hours ago, bartdejonckheere said:1 20:25:32 Willow kernel: usb 5-2: USB disconnect, device number 2This should not happen when you just use another USB port
June 2Jun 2 Author Just now, JorgeB said:The problem was the flash drive dropping offlineThis should not happen when you just use another USB portOooowh, thanks a lot! Yes, I put the USB-drive in the slot next to the flash, I might have bumped it...I'm going to put in a USB-hub, so I can connect to it from the front of my server and don't need to touch anything in the back.And I'm also going to move to internal boot anyway, sooner or later... 😅
