single redis sync to redis cluster

[PhilosophyYuan]

Ask a question rst sync single redis to redis cluster only support db0?

Describe the bug ./rst -s redis://127.0.0.1:6379?authPassword=xx -m redis://128.0.0.1:6379?authPassword=xx -r -d 1

Yes, syncing to a Redis cluster only supports db0 because the cluster has only db0. Therefore, if you want to sync data from other databases to the cluster, you will need to use other methods.

# backup source redis to db0
rdt -b redis://srouce-ip:6379 -o /path/to/dump.rdb --goal 0
# restore to target redis
rmt -s /path/to/dump.rdb -m redis://cluster-ip:6379 -r

if it doesn't work, could you reproduce your steps?

I tried with rdb, but dest cluster no data rdt -b redis://srouce-ip:6379 -o /path/to/dump.rdb --goal 1 rmt -s /path/to/dump.rdb -m redis://cluster-ip:6379 -r

[leonchen83]

rdt -b redis://srouce-ip:6379 -o /path/to/dump.rdb --goal 0 that must be --goal 0 means convert all source data to db0

[PhilosophyYuan]

ok i'll try again. thanks

i want migrate source redis db1 data. I tried rdb again, but there is still no data in the target cluster. The command I entered is as follows:

./rdt -b redis://source-single-redis:6379?authPassword=xx -o ./dump.rdb --goal 2

./rmt -s dump.rdb -m redis://dst-cluster-master:6379?authPassword=xx -r

dest cluster no data

[PhilosophyYuan]

I've solved it, thanks

migrate db1 to db0 should ./rdt -b redis://source-single-redis:6379?authPassword=xx -d 1 -o ./dump.rdb --goal 0
