I am attempting to use an external 4TB HDD with my Roon database backup and music files. This disk was used previously on my MacBook Pro; the HDD has a Thunderbolt 2 interface and was connected to the Mac via a USB-C port, with the Apple Thunderbolt 2 to USB-C adapter. I am using the same USB-C adapter to connect it to Nucleus+. The Disk Utility on a Mac shows the filesystem as “RAID Volume Max OS Extended (Journaled).”
While I can login into Nucleus+ from an iPad, Roon on Nucleus+ does not appear to see the hard disk. It does not seem I should be adding it via the “+ Add Network Share” option, as it is not a network disk? Perhaps the disk filesystem is not compatible with Linux?
What should I do?
I am getting an internal SSD in about 2 weeks, so this problem shall go away, but it’d be good to know a solution anyway.
Also, how do I access Nucleus storage (either an external or internal disk) from a Mac computer on the same network?
well, i am using a Thunderbolt 2 to USB-C Apple’s adapter to connect to Nucleus+ USB-C port.
i also tried two other Mac disks: one SSD via USB-C without an adapter, and a USB-A HDD. none of them are recognized, though I may not have turned the Nucleus+ off and on after connecting the disks (not sure if that is needed).
the Mac Journaled HFSP+ USB-A external HDD was not shown by Roon in its Storage folder, but I am now reformatting the HDD into exFAT, so hopefully this will do the trick. in the meantime, i use music storage on a disk connected to a Mac on the same network, accessing it via smb.
The exFAT HDD connected via USB-A is visible in Storage and works, but I can’t write on it from a Mac that displays the Storage folder via smb. Even though clicking cmd-I on the disk name on a Mac says that I have Read & Write privilege, there is a “red stop” sign on the folder icon and I can’t open it. How do I get r/w permission for it, so I can put new music on this Nucleus+ disk from a Mac?
Hopefully this issue does not occur with an internal SSD (which I will install as soon as I get it in about 2 weeks), or the same solution will apply? How do I format the internal SSD, so that it is accessible (read and write) from a Mac?
i spoke too soon: while i can now go into the USB disk folders on a Mac, i can’t create a folder or a file in them; and Roon’s Backup into it does not work either. the fs of the HDD is exFAT. this is a hassle, as I intended to use a Mac to update music files on the Nucleus.
there is a potentially related problem, and certainly a problem indicating an issue with Nucleus I/O to external USB disks, so i am mentioning it in this thread:
Roon does not see all my tracks anymore. It is missing about 15,000 out of 55,000 tracks. The files are there (I checked by mounting the disk on a Mac, I even synced it again with my master music storage on a Mac): Forcing a re-scan of imported files function in Settings scans the right number of files, but the number of imported tracks is incomplete, missing about 15,000 tracks. Interestingly, cleaning the Roon library (in Settings) shows about 15,000 tracks were removed. So it seems Roon imports them, but then soon decides they are not there, and removes them. Maybe it is a slow disk …
I am waiting on an internal SSD delivery, hoping these problems will go away, but I thought the developers would like to know anyway …
