A lot of that is in formatting and file system overhead. For the last one, df command is showing you how much space is available for a non-privileged user. By default 5% of the space is reserved for use by root. That can be changed via the tune2fs command to something more reasonable for such a large file system.

I set up an LVM with over 30 model 9's and I seem to lose disk space as I go on. When I do a cat on /proc/dasd/devices, it tells me that each of the volumes has 7.042G of space. When I created the LVM, it told me that each volume has 6.88G of space (what happened to 7.042) ? When I do a DF -m command, it tells me that I have 203221M, 1M used and 192898M available. This does not add up (203221 - 1 = 192898 ??). When I do a DF command, it tells me that I have 208097872 blocks, 119036 used and 197408084 available (still does not compute !!!). Where did all of my space go ??? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
