Hi, Gluster expert, I has just raise a bug with https://bugzilla.redhat.com/show_bug.cgi?id=1529237 on gluster community.
I also attached the reproduce source code and shell script here FYI. >From my investigation , I suppose the issue maybe caused by "cache in client >is invalid but the file still not been persistented in server brick" But I can't find the root cause from the debug log which attached in https://bugzilla.redhat.com/show_bug.cgi?id=1529237. >From the following log I abstract client log from the attachment in the >Bugzilla, I highlight it with YELLOW which in read phase, you can see both >volume(test-client-0 and test-client-1) are failed I just suppose it maybe some abnormal when it in read phase, but I can't any usefully log in server brick log from myself, so your helps is highly appreciated!
