Features
= Features Feature difference
* Ext4 supports big cluster sizes (up to 256Mb) with -O bigalloc, while XFS supports only 512b-4Kb cluster size
* XFS supports fully dynamic inode allocation, i.e. you’ll never run out of inodes, and at the same time you don’t need to waste disk space by reserving it for inodes
* Ext4 does NOT support changing inode count without reformatting the filesystem, even with resize2fs; by default, 1/64 of disk space is reserved for inodes (!!!)
* XFS does NOT support shrinking of a filesystem at all (you can only grow it)
