If you dump the values with -e hex option and there should be 24 digits, first 8 represent pending operations on the data of the files (write/truncate). next 8 represent pending operations on metadata (permissions, ownership etc) next 8 represent pending operations on entry (creation/deletion/rename of a file inside that directory). Now if both data/metadata/entry digits are non-zero on a file then that will be split-brain. Example: Data split-brain: trusted.afr.poolsave-client-0=0s000000010000000000000000 trusted.afr.poolsave-client-1=0s000000200000000000000000 Thanks Pranith -------------- next part -------------- An HTML attachment was scrubbed...
