Since updating my laptop to 2.6.23, occasionally all of my free disk space on my root partition will just go away, with no files accounting for the space, with no odd messages in dmesg or my syslog. If I reboot, I immediately have the proper amount of free space again. Here is the output of a du -sx * on /, and the output of the df command when the problem is occuring, followed by the same info after a fresh reboot (literally just did the command in the failed state, then immediately rebooted and ran the same commands again) - any thoughts as to what might be happening? As a note - when I first see the issue, I have exactly 0 free space available on root, as per df - I then delete some random things in order to have enough free space to operate, which is why in my first df you see 55M available Prior to reboot (with issue occurring): charles / # du -sx * 8814 bin 0 boot 132 dev 392 emul 105869 etc 1718345 home 0 lib 4858 lib32 72358 lib64 4 media 72374 mnt 2027054 opt 0 proc 126411 root 15596 sbin 0 sys 28237 tmp 20887995 usr 1098215 var charles / # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda4 37020624 36964772 55852 100% / udev 10240 132 10108 2% /dev shm 1028712 24 1028688 1% /dev/shm /dev/sdc2 73246080 20255824 52990256 28% /media/linux charles / # du -sx totals: 26,166,654 Post reboot: charles / # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda4 37020624 24449440 12571184 67% / udev 10240 132 10108 2% /dev shm 1028712 0 1028712 0% /dev/shm /dev/sdg2 73246080 20255824 52990256 28% /media/linux charles / # du -sx / charles / # du -sx * 8814 bin 0 boot 132 dev 392 emul 105869 etc 1719241 home 0 lib 4858 lib32 72358 lib64 4 media 72374 mnt 2027054 opt 0 proc 126406 root 15596 sbin 0 sys 28249 tmp 20887995 usr 1040963 var charles / # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda4 37020624 24452848 12567776 67% / udev 10240 132 10108 2% /dev shm 1028712 24 1028688 1% /dev/shm /dev/sdg2 73246080 20255824 52990256 28% /media/linux charles / # charles / # uname -a Linux charles 2.6.23-gentoo #1 SMP PREEMPT Tue Oct 16 11:34:08 PDT 2007 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ AuthenticAMD GNU/Linux charles / # mount /dev/sda4 on / type reiserfs (rw,noatime) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec) udev on /dev type tmpfs (rw,nosuid) devpts on /dev/pts type devpts (rw,nosuid,noexec) shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev) usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) nfsd on /proc/fs/nfs type nfsd (rw,noexec,nosuid,nodev) /dev/sdg2 on /media/linux type reiserfs (rw,nosuid,nodev) /media/linux/usr/portage/distfiles on /usr/portage/distfiles type none (rw,noexec,nosuid,nodev,bind) As you can see, the du -sx * gives virtually identical used space (which adds up to about 26G, in both instances), but df thinks that there is no free space available, and I can't write anything to disk (I get a disk full error). Attached is output from lspci -v, and zcat /proc/config.gz Thanks! -James
