    Description

      The meta_bg feature unfortunately fragments the group descriptor block across the whole filesystem, rather than continuously at the start of the device. This causes a large amount of seeking (at least 32768 seeks for a 256TB filesystem).

      Skipping the loading of inode tables and bitmaps via -c will avoid reading many GB of data.
