Re: [gentoo-user] how does Gentoo's mke2fs determine how many inodes to create?

Actually it's really silly of you to have done that for a gentoo root 
partition. You have 16k per inode on average, much more than enough for 
normal purposes so it's a sane default for ext2/ext3.

I'll bet your problem is this:

alan@develop ~ $ find /var/portage/ | wc
 143970  143970 7612245

That 65% of your inodes consumed right there in a required directory 
structure. If so, easiest way out is to boot off a LiveCD, get access 
to the pendrive and reduce it by about 350M or so. Create a new 
filesystem in that space, mount it to $PORTDIR and move your portage 
tree to it.

Someone else will need to confirm how big PORTDIR is on ext2/ext3, as 
mine isn't. Also make sure distfiles is also a separate filesystem.
