Kill both brick processes 2. Edit the changelog on both files on the backend, make them different: getfattr -d -e hex -m "trusted.afr." <my file> You should see something like: trusted.afr.GLUSTER-SHARE-client-0=0x000000000000000000000000 trusted.afr.GLUSTER-SHARE-client-1=0x000000000000000000000000 Next set them to values that clash: setfattr -n "trusted.afrGLUSTER-SHARE-client-0" -v 0x000000000000000200000000 setfattr -n "trusted.afrGLUSTER-SHARE-client-1" -v 0x000000000000000300000000 setfattr -n "trusted.afrGLUSTER-SHARE-client-0" -v 0x000000000000000300000000 setfattr -n "trusted.afrGLUSTER-SHARE-client-1" -v 0x000000000000000200000000 3. Restart both brick processes. 4. Gluster v heal <my vol> info split-brain I haven't done this for a while but IIRC those command will get you there. The -v syntax may not be correct on the setfattr, but this should get you going. -b > thanks > > _______________________________________________ > Gluster-users mailing list > Gluster-users@xxxxxxxxxxx > http://www.gluster.org/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
