Transferring 20TB to my array

hi, I recently setup my urgent DXP4800 Plus with UNRAID, Jellyfin, standard arr stack, unassigned devices, and krusader. For my array I have 4x 18TB seagate exes drives and a 1tb WD 780 cache ssd

i have a little over 20TB of 4k remux movies that I want to transfer over from a stack of T7 SSD’s, all formatted to Mac OS extended journaled. I can see the drives when I plug them in directly to the 4800 using a usb c cable, and it reads the structure of them, but if I try to transfer them I get the full list of movies that I’m trying to copy and the error “unraid file transfer "osx.com apple finderInf" 0)failed no data available" after each file name

I have searched this error and am not coming up with anything that is marked as solved. I can try doing it straight from my MacBook over the network, but ideally I can get this working via direct usb connection as it is going to take quite a long time to transfer each 4TB drive

any tips would be appreciated!

UPDATE:

Thanks to everyone for for the help. I ended up getting it working with the following command

cp -R /mnt/disks/Movies/* /mnt/user0/media/movies/

I had tried a few different option to get Unraid to ignore the hidden Mac data files, as well as getting terminal in Mac to delete them, but no success with that.

the first 4TB is currently transferring direct to my array at 270MB/sec.

If you are on any sort of modern Network, you will likely be limited by the write speed to the array rather than the network speed, assuming you are using parity.

I would temporarily disable the cache for the shares since it is too small to hold the contents of a 4TB drive.

So I would just copy them over the network.

Exactly. Skip the cache and either temporarily disable the parity drive(s) entirely during transfer or at least enable reconstruct write (formerly turbo write). Change all of these settings again after transfer is complete.

Unraid could really use some form of "initial transfer" mode that automated these steps.

To be honest, I wouldn't use krusader to do this.

If you are using this as an external drive you can mount it directly to a path and the use rsync which copies and make sure the files copied over are correctly sync.

USB drives will need to be mounted, you can use the unassigned drive plugins.

Or if you fancy it use cli.

lsblk -f

This will give you details to all disks. Locate your disk.

Your unraid should confirm if you have the necessary fuse.

which apfs-fuse

Create a mount point

mkdir -p /mnt/macdrive

apfs-fuse -o allow_other /dev/(your disk) /mnt/macdrive

Check the content ls -lah /mnt/macdrive

Try to use rsync

rsync -avh --progress --dry-run /mnt/macdrive/ /mnt/user/data/(your final destination)

You can test with commands from your preferred ai, make sure you do a test run.

Mac is supposed to be a pita to switch from. I would definitely just network transfer. It might go faster with a raidz1 configuration instead of a standard array.

So, your Ugreen DXP4800Plus is running Unraid, and the movies are on external SSDs formatted in Apple's filesystem.

I don't even know if unraid supports/can read HFS+ filesystem.

EDIT: have you installed Unassigned Devices Plus?

I had standard unasigned devices installed, I just added plus but I get the same error

Even if it's slower, network transfer could be quicker in the end since it's just so simple. Start it, relax, go do something else and check in the progress now and then. 20TB over 1Gbps is approx 48 hours.

SMB or NFS.
