Restore DB by command line on RavenDB running on Linux

[Vladimir Zlatkovski]

Hello,

I'm running RavenDB on Linux that is in docker container.

I want to write simple powershell script to restore database on the ravendb instance in that linux container.

I've tried to execute the restore command __inside__ the linux machine itself, but I didnt have any luck ( There were shell scripts only for starting the server ... ).

Since the ravendb is available from the linux machie on http://172.17.0.2:8080,  I've tried with locally installed ( on windows machine ) ravendb instance to run this command:  

.\Raven.Server.exe --restore-source="C:\Users\Vladimir\Desktop\data" --restore-database="http://172.17.0.2:8080"

This is the result:

A critical error occurred while starting the server. Please see the exception details bellow for more details:

Raven.Abstractions.Exceptions.BadRequestException: There is no handler for path: POST /admin/restore ---> Raven.Abstractions.Connection.ErrorResponseException: Status code: BadRequest

Does this mean that the restore option is not yet implemented in ravendb 4 or ?

Any idea of doing a restore on the linux ravendb instance ?

Thanks.

This is how you restore in 3.5, not in 4.0

The easiest way to see how to do that in 4.0 is to do that from the studio and pull the curl command from Chrome.

I can not find the restore option in the studio, does it exist in version 4?

I can see that there is only Import option...

Thanks.

Still could not do it...The error says: broken pipe.. 

See screenshot for reference: https://image.prntscr.com/image/yJ6FHuf4SUiEHs3N35wWNQ.png

I'm afraid that importing in this manner requires a Windows machine to run the exec.

So actually we can not do a restore on linux with the current version of ravendb , right ?

[Oren Eini (Ayende Rahien)]

You can do a restore from _4.0_ in Linux, yes. But not from 3.5

Yes, that is available on Windows only.

Export files works everywhere.

Okay..

I've tried to do the restore on windows raven db instance version 4 ( latest one ), from backup of ravendb 3.0 through the studio: https://image.prntscr.com/image/x4v0-4SRT1C0D0xG0TtfZQ.png

This is what i got: 

[3:43:52 PM INFO] Starting migration
The data export tool have exited with code -1073741819.
System.ApplicationException: The data export tool have exited with code -1073741819.

I've tried with the Raven.StorageExporter.exe from tools both version 3.5.4 and 3.5.5 from the ravendb site.

What I am doing wrong .. ?

I don't understand:

I've tried to do a restore on windows ravendb version 4 from backup created from ravendb version 3.0.

OS: Windows 10, x64

RavenDb version: 4.0.0-rc-40025

What I did: Through the studio of ravenDB tried to create "New database from  v3.x ( legacy ) data files" 

Inputs:
             Data directory: path to directory that contains the backup files from ravendb 3.0 ( C:\Users\Vladimir\Desktop\data ) 
             Data exporter: path to exporter exe downloaded from ravendb site ( C:\Users\Vladimir\Desktop\tools\Raven.StorageExporter.exe) 

[Oren Eini (Ayende Rahien)]

Is this resolved?

No, its not.

[Oren Eini (Ayende Rahien)]

Okay, let's get back to the beginning.

Restoring from a 3.x backup requires running on Windows.

You have tried that, and it failed? What is the failure that you got?
