I upgraded the couchbase server installation on my dev Mac from 3.0 to 4.0-RC and when I restarted found that while all the buckets were still there, they were all empty. No design documents, nothing…
This is only a development machine, so the loss of data is not catastrophic, but it doesn’t fill me with confidence for production use…
I don’t see anything in the logs indicating any issues other than this:
Unsuccessful goxdcr upgrade.
{exit,{noproc,{gen_server,call,[xdcr_doc_replicator,{pull_docs,[]},infinity]}},
[{gen_server,call,3,[{file,“gen_server.erl”},{line,188}]},
{goxdcr_upgrade,do_upgrade,2,
[{file,“src/goxdcr_upgrade.erl”},{line,62}]},
{goxdcr_upgrade,upgrade,2,[{file,“src/goxdcr_upgrade.erl”},{line,42}]},
{cluster_compat_mode,do_consider_switching_compat_mode,2,

{ns_orchestrator,init,1,[{file,“src/ns_orchestrator.erl”},{line,325}]},
{gen_fsm,init_it,6,[{file,“gen_fsm.erl”},{line,361}]},
{proc_lib,init_p_do_apply,3,[{file,“proc_lib.erl”},{line,239}]}]}
but this is a single node with no xdcr configured.
Any ideas on what went wrong?
