I got the following error while executing ‘cbtransfer’
struct.error: unpack requires a string argument of length 18
Traceback (most recent call last):
File “_ctypes/callbacks.c”, line 314, in 'calling callback function’
File “/opt/couchbase/lib/python/couchstore.py”, line 408, in callback
File “/opt/couchbase/lib/python/pump_sfd.py”, line 218, in change_callback
cas, exp, flg, flex_meta, dtype = struct.unpack(SFD_REV_META, doc_info.revMeta)
When I looked at ‘Operation per Second’, it seems like the data from fail-over node properly pushed into the running cluster.
But I got very long list of the above error after ‘cbtransfer’ execution, so I am worrying about any data loss.
Would there be any data loss after the error?
