Maximum USB disk size on PRi3 using LibreElec? 16TB disk works, 20TB disk doesn't?

mtrcycllvr · November 9, 2022 at 7:13 AM

I just de-installed a 12TB disk and replaced it with a 20TB disk. I can apply an ext4 filesystem on it, but I cannot mount it and LibreElec is not automounting as I expected.

Have I hit a 32bit architecture limitation?

I thought, well, perhaps if I partition it, but all attempts at using parted to manually create labels and partitions have utterly failed..

I have two of these sort of "all in one" systems, a case, SATA controller, and big SATA disk with a RPi3 - I have one for SURE that is working with a 16TB disk without issue.. I just sort of assumed that an increment to 20TB under ext4 would be just as straight forward?

And, now that I've upgraded from 9.2.8 to 10.0.3, I can't relable the drive as mkfs.ext4 thinks the drive is mounted, which it is not..

Code

TrailerTrash:~ # mkfs.ext4 -F -I 128 -i 67108864 /dev/sda
mke2fs 1.45.6 (20-Mar-2020)
/dev/sda is apparently in use by the system; will not make a filesystem here!
TrailerTrash:~ # mkfs.ext4 /dev/sda
mke2fs 1.45.6 (20-Mar-2020)
/dev/sda is apparently in use by the system; will not make a filesystem here!
TrailerTrash:~ #

I am utterly baffled at this point. The upgrade to 10.0.3 broke my ability to, say, jack with number of inodes or up the block size to perhaps bring things back within limits..

Thanks for any thoughts!
