Multiple Storage

ℹ️ Support

Hello,

I am interested in Nextcloud.
But I have an interesting question.

I have 5 servers, 1 Server for front end, 4 server for server storage.

so the topology is like this.

topology nextcloud
topology nextcloud1053×512 5.82 KB

Nextcloud server is only used for front-end, users who upload files will not enter on the front-end server.

Then each user uploads an automatic file between one storage server.

How to? I still don’t understand. thank you

If you do not use the front end (Web, WebDAV, …) from Nextcloud for uploads you must after upload re-scan the directorys. Perhaps with cron every hour.

https://docs.nextcloud.com/server/18/admin_manual/configuration_server/occ_command.html#file-operations

What is your goal. What is with the uploaded files?
Perhaps Nextcloud is not the correct software for you.
Perhaps you better use browsing through filesystems or an ftp-server.

Perhaps there is also a problem with multiple storage.

hello sir,

I want to like Google Drive for example.

I uploaded the file on the Google drive.
but when I download it, the file is not on Google Drive, but on other storage servers.

How about setting up an iSCSI target on each storage server, and then setting up a RAID-10 volume from those, and placing the Nextcloud data folder on it?

I still don’t understand you guys,

I want to place local storage on server storage 1-4 not on the front end.

Ok, you’ll have to explain more clearly. What do you mean by: “place local storage on server storage 1-4 not on the front end” ? Do you mean place data stored in Nextcloud on these 4 servers? What I just suggested would do that.

7

yes sir, data on storage server 1-4, automatic user if upload or download file on app nextcloud, instance nextcloud not have file, but file location on any server 1-4

So as I said, if you:

  1. Set up an iSCSI target on each of the 4 servers
  2. Connect all 4 targets from an initiator on the Nextcloud server
  3. Set up software RAID using the iSCSI devices
  4. Put your Nextcloud data directory on the iSCSI RAID device

… then the data would be stored on the 4 backend servers, and also be fault tolerant.

InitiatorName=iqn.2020-04.srv2.domain.com:node1node2

what is problem? please help? correction if i wrong

I’m not sure, but it’s definitely a configuration issue because you can connect many targets at once. I do it all the time on VMware ESXi and Windows.

If you’re getting login failure, the problem could be on server 2.
