    • too many Inodes on 80TB filesystem creation

      Hi,
      I'm switching from old data disk raid, to new bigger disks on a hardware raid, omv is installed on debian. The old raid disk was 15TB, the new is 81TB, when I use the web interface to format the filesystem ext4 it assigns 1.3 billion Inodes, which seems excessive. The 15TB disk had 4M, which is maybe a bit low but I was at 45% usage in inodes when at 90% space so.

      Is there a way to lower the inode count for creation? I think fsck with over a billion inodes would have issues or am I living in the past?

      Thanks for any insight.

      Yes, The -N flag of mkfs.ext4 allows you specify the number of inodes. You can't change the number on an existing filesystem though as far as I know.

      I have plenty of drives with 250 million inodes but not using many. fsck isn't an issue. I guess it depends on how many you are using.
