Ah, yes, but I understand on XFS inodes are dynamic, not fixed at format time.
Once I run a test creating many thousands of small files. btrfs was sluggish and finally crashed, ext4 coped till inodes spent, xfs coped well (till disk full of new inodes, IIRC), and reiserfs wanted more.
Yes, this is the point I was trying to make about ext4 still being stuck in the old old model of resource preallocation.
A REAL Btree FS allocates resources dynamically ... all resources. Ext4 just uses Btree mechanisms to pool free blocks rather then the first-in-last-out queue model that the old UNIX V5,V6,V7 used and that was later inherited down the line.
But a filesystem with fixed and known location and size structures is easier to repair in case of disaster. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas)) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
