Missing disk space

From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020916 Description of problem: Here is the output of df on my laptop: [aurag@l0553 aurag]$ df Filesystem 1k-blocks Used Available Use% Mounted on /dev/hda3 2830440 2441768 244892 91% / /dev/hda2 46668 10270 33989 24% /boot none 63112 0 63112 0% /dev/shm /dev/hda1 2677572 2407016 270556 90% /c As you can easily see, all the numbers match for all filesystems except /dev/hda3 where the Available should have been: 388672 and not 244892. Now this is not in my opinion a problem in df itself, but I don't know who would be responsible. Anyway, this is a nasty problem as sometimes the whole system will run out of space even though there are still space there. I am loosing on average about 140 Mb. Another test was that I uninstalled mozilla-mail that takes up about 5 Mb without seeing any change in free space. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: I don't know if you CAN reproduce it. But any tests needed will be run on my laptop. Additional info: I am using kernel: kernel-2.4.18-18.7.x. Also this wasn't like this before but I can't really pin-point when it started to happen.
ext3 file system?
I am sorry. I forgot to give full details. It is an ext3 filesystem It's a Toshiba Satellite Pro 4200 Series.
Sounds like it's the journal.
there is a reserved area of iirc 5% that is for root user only on / df will show what is available for non-root users see tune2fs -l /dev/hda3 output for the Reserved block count: output
I have done it and it looks like you are right. Here is the output: [root@l0553 root]# tune2fs -l /dev/hda3 tune2fs 1.27 (8-Mar-2002) Filesystem volume name: / Last mounted on: <not available> Filesystem UUID: 96e939e8-6aa7-11d6-8f0b-a44ee0cf123f Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal filetype needs_recovery sparse_super Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 359744 Block count: 718908 Reserved block count: 35945 Free blocks: 92901 Free inodes: 260117 First block: 0 Block size: 4096 Fragment size: 4096 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 16352 Inode blocks per group: 511 Last mount time: Fri Jan 10 10:08:14 2003 Last write time: Fri Jan 10 10:08:14 2003 Mount count: 12 Maximum mount count: -1 Last checked: Thu Jan 9 10:11:33 2003 Check interval: 0 (<none>) Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 128 Journal UUID: <none> Journal inode: 8 Journal device: 0x0000 First orphan inode: 21583 And If I do the 4096*35945, I get my 140 missing Mb. Still df should at least report it as reserved or something. It could and is a little weird to see disk space disappear. So I guess it becomes a wish and not a bug. Thanks for your quick treatment.
