Hi, The config file isn't monitored, so just changing the file won't help, you'd need to restart couchdb. Did you have anything bypassed in the first place, though? Could you explain the replication problems you encountered? I can say for sure that it is generally unsafe to modify shard files

Shards cannot be read after move to a different cluster

2022-07-07 Thread Luca Morandini
Dear All, I moved some CouchDB 3.1.0 databases to a new 4-node cluster via copying the shard files. The operation worked for 5 out of 6 databases; the biggest database (about 200GB, 12 shards, 2 replicas) did not come online on the new cluster. I suspect high disk latency, but... could someone s
