Hello, thanks for the answer, I tried to apply your suggestion but it does not work. Although the command tune2fs -m 1 /dev/hdX reports only 1% will be reserved, the subsequent tune2fs -l /dev/hdX still reports 5% reserved (even after reboot for the root partition). Also, when I did "df" before and after, no change. I tried the same for the ohter partitions (/home, /scratch), the same results. But if I re-format them (mke2fs -j -m 1 /dev/hdX), then tune2fs -l reports the correct reserved block amount and also df displays more space on the disk. So the question is: what does the tune2fs -m really do ??? > I have forwarded your mail to our bug tracking system as a wishlist bug > report, perhaps we can add something to allow tweaking of these values > in the installer. Thanks, this would be nice. Best regards Tomas E-mail : davidek@ipnp.troja.mff.cuni.cz, Tomas.Davidek@cern.ch ----- End forwarded message ----- -- see shy jo
