Thanks Austin for the suggestions. I haven't done any deduping, it is a pretty fresh install too (two weeks old). I tried a full balance a few times: # btrfs balan / Done, had to relocate 28 out of 28 chunks # btrfs balan / Done, had to relocate 28 out of 28 chunks After balancing the first time should there be less to rebalance the second time? I tried receive -vv and then deleted the file that was causing the issue but running again the issue happens on a different file: ... utimes var/lib/sudo/hertz truncate var/lib/sudo/hertz/2 size=40 chown var/lib/sudo/hertz/2 - uid=0, gid=1000 chmod var/lib/sudo/hertz/2 - mode=0600 utimes var/lib/sudo/hertz/2 mkfile o189735-35-0 truncate o189735-35-0 size=0 chown o189735-35-0 - uid=1000, gid=1000 chmod o189735-35-0 - mode=0600 ERROR: unexpected EOF in stream. I'm not using any kind of raid. Do you think reformatting the partition or something else might help? Should I try to upgrade the kernel? Thanks for the support.
