Subject: [PATCH 495/511] geo-rep: descriptive message when worker crashes due
 to EIO

With this patch now you can notice log if it is due to EIO:

[2020-03-16 16:24:48.293837] E [syncdutils(worker /bricks/brick1/mbr3):348:log_raise_exception] <top>: Getting "Input/Output error" is most likely due to a. Brick is down or b. Split brain issue.
[2020-03-16 16:24:48.293915] E [syncdutils(worker /bricks/brick1/mbr3):352:log_raise_exception] <top>: This is expected as per design to keep the consistency of the file system. Once the above issue is resolved geo-rep would automatically proceed further.
