$ df -hi /home Filesystem Inodes IUsed IFree IUse% Mounted on $ df -h /home Filesystem Size Used Avail Use% Mounted on

This situation can be evaluated by comparing the Use% and IUse% figures provided by df and df -i: 256 * several millions = quite a few gigabytes wasted in unused inodes. This results in a waste of disk space, because all those unused inodes each take up 256 bytes on the filesystem (this is also set in /etc/nf but should not be changed). However, for partitions with size in the hundreds or thousands of GB and average file size in the megabyte range, this usually results in a much too large inode number because the number of files created never reaches the number of inodes. If the inode count is too low, no file can be created on the filesystem even though there is still space left on it.īecause it is not possible to change either the bytes-per-inode ratio or the inode count after the filesystem is created, mkfs.ext4 uses by default a rather low ratio of one inode every 16384 bytes (16 KiB) to avoid this situation. The larger the bytes-per-inode ratio, the fewer inodes will be created.Ĭreating a new file, directory, symlink etc. Mke2fs creates an inode for every bytes-per-inode bytes of space on the disk. If supported, you may want to enable metadata checksums.See mke2fs(8) for more options edit /etc/nf to view/configure default options.It looks a bit odd, but it seems to work. In my case, I mounted /dev/sdb instead of /dev/sdb5. That is I pretended that disk0s5 is a whole disk. In my case, I ran something like:Ĭode: Select all Expand view Collapse view sudo VBoxManage internalcommands createrawvmdk -filename /Path/to/vmdk/filename.vmdk -rawdisk /dev/disk0s5 Personally, I've found some troubles to work around, but they might be related to the fact that I needed to access partition #5 (and there's a bug for partitions beyond #4). Now you should be able to mount /dev/sdb4. That should report that the former is a boot sector with partitions, the latter is an ext4 filesystem. From the guest, you can confirm the status of your disk with the following commands:Ĭode: Select all Expand view Collapse view % head /dev/sdb | file. At this point, you should have /dev/sdb in your guest that is mapped to /dev/disk0 of your host. vmdk as a disk in the 'Storage' settings of your guest (SATA disks). Ok, I was just able to get a similar thing working (I had problems on my own), so I can give you an answer.
