I have a 5TB drive attached via USB3 to machine running Xubuntu. The drive is formatted with a single NTFS partition. I'm trying to copy about 400GB of files to it, and it has way more than enough space as per the entry for /dev/sdb2 below:
df -hFilesystem Size Used Avail Use% Mounted onudev 32G 0 32G 0% /devtmpfs 6.3G 18M 6.3G 1% /run/dev/sda2 410G 319G 70G 83% /tmpfs 32G 152K 32G 1% /dev/shmtmpfs 5.0M 4.0K 5.0M 1% /run/locktmpfs 32G 0 32G 0% /sys/fs/cgrouptmpfs 6.3G 36K 6.3G 1% /run/user/1000/dev/sdb2 4.6T 275G 4.3T 6% /media/josh/5TB-2016-05-08
When searching for the source of this error a common problem raised was not having enough inodes, but that doesn't appear to be the problem here:
df -ihFilesystem Inodes IUsed IFree IUse% Mounted onudev 7.9M 570 7.9M 1% /devtmpfs 7.9M 867 7.9M 1% /run/dev/sda2 26M 679K 26M 3% /tmpfs 7.9M 7 7.9M 1% /dev/shmtmpfs 7.9M 5 7.9M 1% /run/locktmpfs 7.9M 16 7.9M 1% /sys/fs/cgrouptmpfs 7.9M 22 7.9M 1% /run/user/1000/dev/sdb2 4.3G 489K 4.3G 1% /media/josh/5TB-2016-05-08
I also ran across this. Even though the drive isn't really very close to have a TB written to it, I tried unmounting and remounting it with the inode64 option, but not joy (yeah, its different filesystem).
It doesn't matter if I copy all of the files at once, or do it directory by directory. Ultimately I start getting "No space left on device" errors before all of the files are copied.
