Inodes disappearing

[Jan Engelhardt <jengelh@xxxxxxxxxxxxxxx>]

Hello list,


here's an interesting phenomena I am seeing:

# df -h
/dev/hda3             215G  152G   63G  71% /sam224
/dev/dm-0             233G  233G  350M 100% /sam250
# df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/hda3            112254144   33076 112221068    1% /sam224
/dev/dm-0            1466272   35982 1430290    3% /sam250

How come that dm-0 has much less inodes despite the two volumes having 
about the same size? It can't be because of isize=512, can it? (If at 
all, I would expect an isize=512 volume to have less inodes than a 
isize=256 one for the same number of blocks.)
