Re: [opensuse] What means this disk error? (Possible kernel bug)

Google hits would suggest the drive is failing, can not allocate replacement
sectors, or some such.

http://serverfault.com/questions/407007/what-do-these-disk-errors-in-syslog-mean

However there are other indications that it is spurious, and the message
results from a kernel
bug:

What should I look at?

The disks are inside an USB enclosure, connected to a 13.1-32b machine.


To run smartctl on it I have to stop the machine and take the disk to another
machine that has SATA,
because:


AmonLanc:~ # smartctl -a /dev/sdb
smartctl 6.2 2013-07-26 r3841 [i686-linux-3.12.62-52-default] (SUSE RPM)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

/dev/sdb: Unknown USB bridge [0x0c0b:0xb136 (0x108)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

AmonLanc:~ #




Looking carefully, messages start on 2016-09-19T14:58:37.943377+02:00, just
after I applied a kernel
update and rebooted:


2016-09-19 14:58:36+02:00 - Booting the system now
================================================================================
Linux AmonLanc
3.12.62-52-default #1 SMP Wed Aug 10 18:37:26 UTC 2016 (069dc39) i686 i686
i386 GNU/Linux


I will have to revert that upgrade :-(
