unRaid Error : kernel: Buffer I/O error on dev sdb1, logical block 9959896, async page read

Happy Christmas everyone.

 

Just a quick post. My server seemed to stop Plex and various other dockers early on Christmas morning and I rebooted and it all seemed to work ok. Plex now works. However, looking at the logs I get the following errors:

 

Dec 25 14:40:06 PCServer kernel: Buffer I/O error on dev sdb1, logical block 9959896, async page read
Dec 25 14:45:06 PCServer  ntfs-3g[10525]: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Dec 25 14:45:06 PCServer  ntfs-3g[10525]: Failed to read vcn 0x0 from inode 5: Input/output error

 

which repeats every few minutes. I attach the logs file also to this post. PCServer is the name of the unRAID server.

 

I have checked all disks, cache disks and m2 drives and nothing is showing any errors. I have replaced cache drives before this this error seems to be very different. I wondered if it was the USB stick but again that seems ok and the system boots fine. 

 

I am now wondering if it's maybe a Windows VM?

 

Can anyone point me in the right direction? Many thanks for any help.

Check filesystem on the NTFS UD device.

Just an update on this error message. The server is working perfectly but the following messages appear every 5 minutes in the log:

 

Dec 25 14:40:06 PCServer kernel: Buffer I/O error on dev sdb1, logical block 9959896, async page read
Dec 25 14:45:06 PCServer  ntfs-3g[10525]: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Dec 25 14:45:06 PCServer  ntfs-3g[10525]: Failed to read vcn 0x0 from inode 5: Input/output error

 

(Exactly the same three lines of error that occurred on Christmas Day, as today).

 

As per the advice from JorgeB, I checked the disks but I don't have a disk assigned as sdb in the array or as an unassigned disk. I have an external disk via a usb enclosure separate to the array which is used to hold security camera footage from Blue Iris which runs as a Windows VM. That is also working perfectly.

 

If anything this is more of an irritation to know what it is! Any help is greatly appreciated.

Reboot.
