Hi,

i have a little problem. I use borgmatic and have mounted an external USB Drive to the borgmatic container.

So the mount point for example is "/mnt/disks/externaldrive" and i use the same path in the borgmatic container as "Read/Write - Slave" access mode.

 

The problem is now after some time, be it days or 1-2 weeks. The complete server is getting something like stuck. Cant shutdown the server, open logs from webgui, cant update plugins, etc. The borgmatic backup job fails.

I found out the problem is my external drive, i cant unmount it or do anything with it.

The only solution is to disconnect the drive and everything is back to normal.

 

My idea was now to check the disk if there is something wrong, it is a important backup disks so it would be important to keep the data alive. Could it be possible that i mount the drive wrong to the container?

Anybody can tell me how i could start a repair/check of the filesystem? I am from the windows world and i am looking something like "chkdsk"

 

Log from the drive when the errors started and disconnecting and connect it again.

Has anybody an idea? Couldnt find much information how to check the filesystem on a luks encrypted partition.

First you need to decrypt the device, you can replace externaldrive with any name you want:

 

cryptsetup luksOpen /dev/sda1 externaldrive

 

After entering the correct passphrase you can then run fsck, for example for a xfs formatted drive it would be:

 

xfs_repair -v /dev/mapper/externaldrive

 

 

Forgot to mention, with the info you posted I'm not seeing anything that points to issues with the filesystem, but that's how you run it.

Thanks for the information.

Do you have an idea what the problem could be?

Do i need to mount the drive in another way? In the timeframe the blk_update error occured nothing special happened on the server.

 

Could it be that the external exclosure is broken or with the usb connection?

Not with the information posted, full diags might show more, also worth trying to connect the drive to a SATA port.

I checked the log and maybe i found already why this is happening, something in my USB 3.0 controller is resetting.

kernel: program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO (i dont think its related but its the error above)

kernel: usb 5-1: reset SuperSpeed Gen 1 USB device number 2 using xhci_hcd

 

I checked the syslog, do you have any idea where i could look next for more information?

I am not a friend to share my log and with it so much information, i would be really happy if you could help me with some information

 

This is the USB Controller information:
 

04:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller [1912:0014] (rev 03)
    Subsystem: Hewlett-Packard Company uPD720201 USB 3.0 Host Controller [103c:1996]
    Kernel driver in use: xhci_hcd
