Hi,So, I just want to know is this feature of file will effect gluster to identify the split-brain or xattr attributes?Means in this file we are doing the wrapping of the data as well.Hi Ravishankar,I just want to inform that this file have some different properties from other files like this is the file which having the fixed size and when there is no space in file the next data will start wrapping from the top of the file.
No it shouldn't matter at what offset the writes happen. The xattrs only track that the write was missed (and therefore a pending heal), irrespective of (offset, length).

Ok, just to confirm, glusterd and other brick processes are running after this node rebooted?
When you run the above command, you need to check /var/log/glusterfs/glfsheal-volname.log logs errros. Setting client-log-level to DEBUG would give you a more verbose message
Yes, glusterd and other brick processes running fine. I have check the /var/log/glusterfs/glfsheal-volname.log file without the log-level= DEBUG. Here is the logs from that file

Not sure why ^^ occurs. You could try flushing iptables (iptables -F), restart glusterd and run the heal info command again .
No hint from the logs? I'll try your suggestion.

# gluster volume heal c_glusterfs info split-brain
c_glusterfs: Not able to fetch volfile from glusterd
Volume heal failed.
And based on the your observation I understood that this is not the problem of split-brain but is there any way through which can find out the file which is not in split-brain as well as not in sync?
`gluster volume heal c_glusterfs info split-brain` should give you files that need heal.
Sorry I meant 'gluster volume heal c_glusterfs info' should give you the files that need heal and 'gluster volume heal c_glusterfs info split-brain' the list of files in split-brain.
The commands are detailed in https://github.com/gluster/glusterfs-specs/blob/master/done/Features/heal-info-and-split-brain-resolution.md
Yes, I have tried this as well It is also giving Number of entries : 0 means no healing is required but the file /opt/lvmdir/c2/brick/logfiles/availability/CELLO_AVAILABILITY2_LOG.xml is not in sync both of brick showing the different version of this file.
You can see it in the getfattr command outcome as well.
