I’m trying to format and mount a 8TB external as an ext4 and it doesn’t seem to work right.
I can create my partition using gdisk:
sdc 8:32 0 7.3T 0 disk └─sdc1 8:33 0 7.3T 0 part
But when I create the filesystem I get a weird error that says: “/dev/sdc1 is not a block special device.” however it seems to complete:
# mke2fs -t ext4 /dev/sdc1 mke2fs 1.42.9 (28-Dec-2013) /dev/sdc1 is not a block special device. Proceed anyway? (y,n) y Discarding device blocks: done Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 246512 inodes, 984801 blocks 49240 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=1008730112 31 block groups 32768 blocks per group, 32768 fragments per group 7952 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736 Allocating group tables: done Writing inode tables: done Creating journal (16384 blocks): done Writing superblocks and filesystem accounting information: done
Afterwards though, when mounting it doesn’t seem to work and it mounts
/dev/loop0 instead? I’m not even sure what that is and the filesystem is the wrong size.
/dev/loop0 4.0G 16M 3.7G 1% /mnt/test
I was reading apparently this is some new type of drive with sectors not in the normal place? Any help would be appreciated.
