You appear to not understand what an inode is. The inode IS THE FILE. It's a specially formatted block on disk, the filesystem knows how to interpret it, and it contains all known information (except one piece) about the file - as in, everything that ls can display. The missing bit of information is the name you call it by, that is stored in the directory (which is really just a special file and contains file names and their corresponding inode numbers - this is how the fs driver finds files). When you copy a file, the inode is read and a new one initialized in the new location. Then the disk blocks are read from the original and copied to the destination. As the destination does this, the fs driver knows how to keep it's inode accounting intact. So, there is no such thing as an extraneous inode. It's either being used (and thus gets copied) or it is not used (and does not get copied). You cannot copy a file without copying it's inode, and you cannot copy an inode without copying the file (special exception - files of zero length). > > This will create a file system with three times as many indoes as you > > had before. > > Is 3x enough?

Use "find -x | wc" on an existing machine per mount point to get a rough idea of the scale. > FWIW, I thought I'd chroot in and do an emerge -C mozilla-firefox but > it hadn't even been installed yet!

You have used up all the "index entries" for files, and you are trying to create more files. What else could it do apart from fail? Log onto the machine and delete some stuff. Then try unmerge to free up more space. Then backup, reformat, restore. -- alan dot mckinnon at gmail dot com
