For example, "/dev/*" files don't require much actual file system space, but a disproportionate number of file pointers are required. I believe this is controlled by reducing the bytes/inode setting in mke2fs (but I forget). My lvmcreate_initrd says: "mke2fs -m0 -i 1024 $DEVRAM $INITRDSIZE" The way to test this is to execute each of the commands in lvmcreate_initrd manually: when the error occurs, return to the point where "mke2fs" is run using a different value for "-i". You should at least see the error messages start on different files for each iteration. Note that a lot of the commands used in lvmcreate_initrd pipe their error output to /dev/null. Don't do this during testing. Also, are you sure your ramdisk size is 8MB? The default is 4MB: it needs to be set on the lilo command line or when configuring the current kernel. I think this is a mistake... since the initrd is not necessarily being built on the same system where it's going to be used, ramdisks should be avoided (since it may require rebooting if you're not already setup for 8MB ramdisks), using a loopback filesystem would be easier (if it's not currently part of the kernel, then the module can be loaded -- no reason to reboot).
