question describtion:
our customer rebalane one node cost 3hours and failed
my workmates saids that the old version like version 5.x and version4.x seems not low like this
so please help me to confirm, why the couchbase is so slow when rebalancing
we created 21 buckets using restful api like below
curl -X POST \
-u couchbase:couchbase_pass \
-d authType=sasl \
-d bucketType=couchbase \
-d flushEnabled=0 \
-d name=bucketName\
-d parallelDBAndViewCompaction=false \
-d ramQuotaMB=100 \
-d replicaIndex=1 \
-d replicaNumber=1 \
-d saslPassword=bucketNamePass \
-d threadsNumber=8 \
http://${COUCH_HOST}/pools/default/buckets
curl -X PUT \
-u couchbase:couchbase_pass \
-d name=geofence-msgmeta \
-d roles=bucket_full_access[bucketName] \
-d password=bucketNamePass \
http://${COUCH_HOST}/settings/rbac/users/local/bucketName
couchbase server info:
hardware info: 8 core cpu 32 g memory 200g disk
version 6.5 enterprise and version6.6 commiunity
test: two nodes cluster scenarios
the cluster server just create 21 buckets and no data save, just join the new node like above 3 different scenarios
- version6.5en as cluster and join version6.6ce
- version6.5en and version6.5en
- version6.6ce and version6.6ce
the memeory is enough
get cpu info:
get disk info:
get rebalance info take long time:
the rebalance faild info
