rsync between two external hdds caused rootfs vanished

[Jerry Jyrer 1]

Board: Nanopi M4 with 4GB

OS: Armbian_5.65_Nanopim4_Debian_stretch_default_4.4.162

Boot from SD, rootfs on an external HDD 8TB (WD MyBook).

 

I attached another external HDD (Toshiba 2TB). I have been trying rsync -avh from the Toshiba one to the main MyBook one. It ran for under a minute before reporting files were vanished and exited with errors. It appeared the / is gone. nothing return from ls. Hard-reboot, fsck ran, everything's back to normal. 

 

I've been trying rsync with nice -n 20 as well as --bwlimit 10, 1MB. Nothing helped.  stress test the board for 10 minutes, (stress -c 4 -m 4 -d 4 -i 4). All looks good. 

 

Any help's appreciated.

 

Thanks,

Jerry

Please provide the complete rsync command (with directorynames).

Are you sure that you didnt overwrite something important with the rsync command on your root-device.
Why do you want to rsync from the Toshiba to the WD MyBook root-device?

 

BTW: I also got a "old" WD MyBook device, but wouldnt use it as a root device, because this "thing" goes very oft in sleep/ide-state and spinning down.

$ sudo mount /dev/sdb1 /mnt

$ sudo mkdir -p /MyBackup

$ sudo rsync -avh --progress /mnt/ /MyBackup/

 

Well as for the reason, (1) testing and (2) mainly, 3-2-1 backup. 

 

Another observation, 

$ sudo smartctl -x /dev/sda1

 

showing:

 

SMART support is:     Unavailable - device lacks SMART capability.

 

pretty weird. 

 

I'm running 

 

$armbianmonitor -c "$HOME"

 

to test my new 8TB MyBook now. It will take awhile but so far so good. I believe it's finishing writing >1TB; 7TB to go.

the commands does look OK for me (referencing to https://www.howtogeek.com/135533/how-to-use-rsync-to-backup-your-data-on-linux/ )

 

just a shot in the blue - try to mount the Toshiba not directly as /mnt but as /mnt/toshiba

 

How are the drives connected to the NanoPi M4?  USB 3.0 or SATA?
Which filesystem do you use (MyBook I think ext4 - but is the Toshiba also ext4 or something like NTFS)?

 

Testing the MyBook is a very good idea

If you are doing backup of currently running rootfs, be careful not to backup some virtual folder such as /dev, /proc, /run, /sys and /tmp, neither /lost+found ...

Thank you. Yes I'll be aware. Currently, all is pure data.

Yes, the media test is still on going. I'll test out /mnt/toshiba mount point once the test finished.

 

My book is ext4. Toshiba is NTFS. Both of them are connected to USB 3.0 ports. There 4 of them on NanoPi M4. I tried all of them and got the result.

[Jerry Jyrer Topic author 1]

Just back from the holiday. I tested the media. Both hard drives are healthy. I tested to mount /mnt/toshiba. Same problem. rsync just quited and after that no files seem to be mounted. A hard restart (pulling of power) was required.

 

Here is $sudo armbianmonitor -u

Just after the restarted with the Toshiba unattached.

Any help would be appreciated.

I may be having a similar problem.  I am using a NanoPi Neo4 and my root filesystem is on eMMC, but I have a large RAID6 attached by USB, on which I back up my server (this box lives at a family member's home, offsite).  The RAID used to live on a SheevaPlug, but I've replaced it with the NanoPi because of performance issues.  (Got a good decade out of the Sheeva!)

 

The RAID devices seem to disappear as soon as heavy I/O occurs.  It first occurred when I started an rsync from my server.  Rebooting the system became impossible without disconnecting the USB hub because the RAID rebuild would cause the same problem to recur immediately.  This was all with a four-port hub connected to the USB 3.0 port.

 

I initially thought it was a power issue, so replaced the four-port unpowered hub with a ten-port powered hub (I don't need ten ports, but I had this unit kicking around).  This did nothing to cure the problem.  What did solve the problem was moving the hub's connection from the USB 3.0 port to the USB 2.0 port.

 

I'm not sure if it's significant, but I notice in /boot/armbianEnv.txt:

usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u,0x0bc2:0x331a:u,0x0bc2:0x3322:u
 

And my hard disks are in that quirks "blacklist":

root@nobby:/boot# lsusb | grep Seagate
Bus 005 Device 009: ID 0bc2:3322 Seagate RSS LLC 
Bus 005 Device 008: ID 0bc2:331a Seagate RSS LLC

Yes, exactly what I finally solved my problem. Same to you Jim, I initially thought and be advised by many that it was the power problem but at the end what solved was to connect one with an USB 2.0 port.

So then the question is: is the USB 3.0 hardware bad on this device, or is it a driver issue and it can be corrected?

 

I've certainly found USB 3.0 to be a delicate thing compared to USB 2.0.  I've had many, many difficulties with 3.0 (all surmounted over time, thankfully, save this one).  The only issue I ever had with 2.0 and Linux was a using-the-port-at-1.1-speeds problem; everything still worked.

 

If I can do anything to help give diagnostic information to developers, please let me know, but it sounds like this problem is easily reproducible.

Totally agreed. I posted here and similar topics for the same issue but so far no real solutions. Many suggestions were around under voltage being supplied. I personally doubt if that is the root cause. 

 

Armbian software/driver itself? Not too sure I tried the stock one from FriendlyElec, the result is the same. Is it the upstream Linux? Possible but no verification. I have just tried after recent apt update and upgrade. The same problem is still reproducible.

Quick scan, it looks like the same. Solution / root cause?

I have no clue but if the problem is shared across devices of Rockchip, could it be a Rockchip, chipset /usb host controller issue? something Rockchip has to fix? I have heard the Odroid XU4 has no such issues (not Rockchip CPU, Exynos) or the 'up board'(Intel)

 

this is after you rule out the adequate power question(which I believe is not the problem)
 

[Mathias 1]

Jumping in a little late, but on the RockPro64 (also Rk3399), the same kind of problems happen (also very easily reproducible, it happens every single time under load). See my post on Pine64's forums. I am in contact with them (well, so far they just keep bouncing me around to another forum / email / person...) to try learning from them if they ever managed to get some sort of usb3 working on this board. Other people are also wondering if the hardware is the root cause of these issues...
