Replicated datasets does not show in dir listing

[eccevery]

Since migrating from FreeNAS to TrueNAS I've been having some issues with replication. I started another thread on the replication issues itself, but at this point I have managed to get around it and now replication is running but I cant see any files on the target server.

Quick background: After upgrading to TrueNAS 12 replications stopped working. I tried to start replication over (deleting snapshots, replication tasks etc) but no matter what I did the replication either failed or replicated a few kilobytes. I finally worked around the problem by manually copying files to a new harddrive I installed temporarily in the main storage server and then replicated THOSE datastores.

The problem is that I cannot see the files on the target device:

However, the datasets show up in the GUI under storage and in zfs list:

I suspect this may have to do with nested datasets that I have created on the temporary disk that I used to created replications from. I created a dataset on the temprary drive called "backup_pool" and on that drive several child datasets. Three of those you see in the screenshot above (replicated to the backup server). I have not replicated the "backup_pool" dataset, maybe that somehow messes things up? This is the replication settings for the music dataset:

I'm a bit confused and don't really know what I'm doing at this point. Have I set up the replication wrong somehow? Wy does not anything show up in the backup server on tank2?

Solved it! Dataset on target server was read-only, causing filesystem to not mount:

Code:

root@pluto:/mnt/tank2 # zfs get all tank2/music_backup
NAME                PROPERTY               VALUE                    SOURCE

tank2/music_backup  exec                   on                       default

Tried to mount it:

Code:

root@pluto:/mnt/tank2 # zfs mount tank2/music_backup
cannot mount '/mnt/tank2/music_backup': failed to create mountpoint: Read-only file system

Checked the settings on target server pool:

Changed read-only setting to false, mounted filesystem and all looks good!
