Ah yes... My partition is only 10GB, and mkfs.ext4 sais in its man page
(at "-N" option) it uses a "calculation [..] based on the number of
blocks and the bytes-per-inode ratio". So a small partition will have
fewer inodes than a big partition.

mkfs.extX uses settings for the inode-block-ratio from /etc/mke2fs.conf.
The "-T" option configures which one to use, my partition falls into
category 512MB < "default" < 4TB, which makes it use inode_ratio=16384.
I think I should use the "news" type. It has inode_ratio=4096, which
should give me 4 times the inodes.... testing... yes: 2621440 inodes
instead of 655360.

Previously I used reiser3fs for this kind of filesystem usage, but it's
not faster than extX anymore. Moreover it's running on a SSD now, and
afaik reiser3fs doesn't support TRIM :(

OK - thank you all. It seems I'll have to reformat.

Bye,
Daniel
