How to export from Redis to MongoDB? (My database got wiped)
-
Why don't you try AOF instead of RDB?
It can save every second, without any certain performance loss. The only disadvantage is that it uses more disk space. -
Another idea would be to configure a cronjob running every X minutes, copying the database.
cp -R /var/lib/redis.rdb /root -
@wellenreiter are you also a OVH user?
-
@AOKP not sure what you mean with OVH and I'm not the one who leased the host, but it's a linode server, so I assume it's a virtual machine
-
@wellenreiter OVH is an ISP, providing servers.
However, I can only assume that something is wrong with your Redis setup or servers.Does anyone uses the Redis repo from Chris Lea?

Also as mentioned above, my redis configuration is 99.9% the default config -
@wellenreiter as said. I am running Redis since May and never had a problem similar to this.
The whole case is indeed very strange... -
It is really strange and if you count all the different installations mentioned here and in the thread 'lost all my data' I doubt, that it is related to the redis configuration
-
@wellenreiter but then again, why the issue appears also on different NodeBB versions?
Maybe really give the PPA Repo from Chris Lea a try or switch to MongoDB. -
@mikep I used NodeBB 0.7.2, 0.8.x and now 0.9. 16GB DDR4 ECC RAM, Intel Xeon E5-2690v3, RAID10 Intel 750 NVMe.
I even had Redis 2.8.x running (current one is 3.0.5).By the way, it means NodeBB or something else would have to make a "FLUSHDB" request, except it is a memory error.

FYI I have had the same problem. I am using a digital ocean 4GB RAM/2CPU VPS with Ubuntu 14.04, nodebb 0.81 and redis 3.04, so I don't think that it is provider/config related.
mmmm, wait. That is almost exactly our dev forum setup. The only difference is nodebb .9
Lost two days of talk between devs and admins...

I had back this problem a 2nd time 2 days ago, I don't know if it's related but I was doing iptables FW settings on the VM, I had nodeBB running, and also redis and from my computer desktop redis desktop manager connected to DB.
Then I made a mistake in iptables, blocked all redis port (even local), saying nodebb unable to connect to redis (so as redis desktop manager) then when I openned back 6379 port, all data was gone, not sure if it's related, just an information.
