I'm formatting a new disk and running mkfs.ext3. I asked for 25000 inodes with "-N 25000", but it gave me 118,272 inodes.
What did I do wrong?
How big is the device? What other info is generated -- block size, journal size, ...? Perhaps try a dry run with -n -v
25000 is a small number for the total number of files and dirs. The number of inodes must permit accessing the full disk at some point. I know that XFS will add inodes if it needs them but I do not know about ext3.
Still it could be possible on a small enough device.
I see on this box: $ df -i | egrep File|boot Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda1 50200 41 50159 1% /boot
$ df -h | egrep File|boot Filesystem Size Used Avail Use% Mounted on /dev/sda1 190M 22M 159M 12% /boot
Since I have discarded USB keys bigger than this I wonder if 25000 is sane and you are hitting some internal sanity check. It also seems that there are more defaults and knobs than I knew... see /etc/mke2fs.conf Read about and try the "-T" flags...
