Convoy NFS - not able to restore volume from backup

Convoy
1

Hello,
I was trying to use convoy-nfs and have a couple of issues.

When trying to Add volume using API and specifying driverOpts, as --backup=vfs:///mnt/whatever/ the convoy storage pool creates a volume, but when mounting it, it appears to be empty. It seems like it can’t find the backup to restore from, or I just can’t make it work?

Thanks,
Alex

Hi akurkin,

Backup is a certain object Convoy already created beforehand. Please refer to our README.me and https://github.com/rancher/convoy/blob/master/docs/cli_reference.md for more details about create/backup.

yup, and we’ve created backup in advance, and made it available on NFS share.

Convoy CLI can see the backup, it’s just that Rancher can’t create a volume from that backup.

Is it even intended to work that way?

Could you show the cmd?

As well as result of convoy backup inspect <url>?

Sure

Result of backup inspect below

$ sudo convoy backup inspect vfs:///mnt/test/convoy/backups?backup=3442c7cc-aef9-48a0-a7dc-93f5ae67935f\u0026vo lume=276ff041-c0e9-446a-8c9b-200e5c56a916 { "BackupURL": "vfs:///mnt/test/convoy/backups?backup=3442c7cc-aef9-48a0-a7dc-93f5ae67935f\u0026volume=276ff041-c0e9-446a-8c9b-200e5c56a916", "BackupUUID": "3442c7cc-aef9-48a0-a7dc-93f5ae67935f", "CreatedTime": "Sun Mar 13 08:37:23 +0000 2016", "DriverName": "vfs", "SnapshotCreatedAt": "Sun Mar 13 08:36:06 +0000 2016", "SnapshotName": "snap_test_vol2", "SnapshotUUID": "cff68c38-eaf2-4f3e-ae40-87f4e808704f", "VolumeCreatedAt": "Sun Mar 13 08:31:39 +0000 2016", "VolumeName": "test_vol2", "VolumeSize": "0", "VolumeUUID": "276ff041-c0e9-446a-8c9b-200e5c56a916" }

And via Add Volume button in UI on storage pools section in Rancher, trying to create a volume with my name, driver set to convoy and driver options have this flag: --backup vfs:///mnt/test/convoy/backups?backup=3442c7cc-aef9-48a0-a7dc-93f5ae67935f\u0026volume=276ff041-c0e9-446a-8c9b-200e5c56a916

Hi akurkin,

I don’t think we’ve added backup support to driver options through UI yet…

You can file a bug for it.

I tried API call, which didn’t work too, is it not implemented as well?

8

API to Rancher? Or use Convoy CLI directly?

We haven’t implemented the API with Rancher for this.

Yes, it was an API call to Rancher. There was an attribute driverOpts,which I thought will do the job :slight_smile: Ok, I see now that we should use only Convoy CLI for this.

Any plans on integrating this to Rancher?

Not currently. But you can file a feature request for it. :slight_smile:
