When using ext2, ext3 or ext4 on a small partition (less than 8GB), then the file system must be created with the proper options to reserve enough inodes. The mke2fs application uses the "bytes-per-inode" setting to calculate how many inodes a file system should have. On smaller partitions, it is advised to increase the calculated number of inodes.
This message, "The file system is not clean, please..." is to notice the user to do the file system check to make sure the data integrity. Generally, it happens when the data volume is not un-mounted properly. It could be: The abnormal shutdown or force power off the NAS. Some services are not stopped properly during the shutdown. ext4 file-system max inode limit - can anyone please explain? Ask Question ... Specify the bytes/inode ratio. mke2fs creates an inode for every bytes-per-inode bytes of space on the disk. The larger the bytes-per-inode ratio, the fewer inodes will be created. This value generally shouldn't be smaller than the blocksize of the filesystem, since ...

Re: Ideal bytes-per-inode ratio for a 8TB partition mke2fs (mkfs.ext4) has some profiles for common use cases, see /etc/mke2fs.conf or -T usage There are some profiles for large files which is suitable if you're not going to extract a kernel source tarball on it (lots lots lots of tiny tiny tiny files).

Qnap file system option bytes per inode

On this quick article, we are going to present you tips on how to enhance the variety of inodes in a file system in Linux. When creating a brand new file system on a partition, you need to use the -i choice to set the bytes-per-inode (bytes/inode ratio), the bigger the bytes-per-inode ratio, the less inodes will probably be created.

A new file system can be created with a higher inode to space ratio by using the -i* option in **mke2fs command:-i bytes-per-inode Specify the bytes/inode ratio. mke2fs creates an inode for every bytes-per-inode bytes of space on the disk. The larger the bytes-per-inode ratio, the fewer inodes will be created.
bytes-per-inode determines how many inodes are created for that file system; inode-size determines how big each of those inode is. You need a lot of inodes if you intend to put lots of small files (&/or lots of directories) on the filesytem.

When you make a new Ext3 file system, you can specify the inode size and bytes-per-inode ratio to control inode space usage and the number of files possible on the file system. If the blocks size, inode size, and bytes-per-inode ratio values are not specified, the default values in the /etc/mked2fs.conf file are applied.
