[Ocfs2-users] error messages in syslog with reflink

[Gang He]

Hello Lentes,

 From the kernel message, it looks reflink in kernel-space did not succeed.
Could you reproduce this bug stably? e.g. use a script to trigger this 
problem.
Second, please share your Linux kernel version, and related HA 
configurations.


Thanks
Gang
