Hello, I have a small server running a tool (RT : perl + mysql + apache) for our support team. I stripped down everything else. The OS is CentOS 4.8. I noticed a difference between df and du which is hard to believe : according to df, I am using 29 GB [root at cedrat-rt ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 33G 29G 2.8G 92% / none 506M 0 506M 0% /dev/shm (there are no other partitions - ok, I could have partitioned it a bit more) but according to du -kshxc /* my largest directory is /var (because of mysql) and the grand total is 19 GB I have a 10 GB difference between both outputs. I verified with tune2fs -l /dev/sda1 (...) Block count: 8703205 Reserved block count: 435160 that is, the ordinary 5% the journal size : debugfs -R "stat <8>" /dev/sda1 yields Size: 33554432 with a block size of 4096, this gives 128 MB I rebooted on the CentOS v4.8 CD #1, started "linux rescue" : mounting /dev/sda1, I get the same 29 GB used e2fsck reports a clean filesystem e2fsck -f does not reports further errors. Does anybody have a suggestion ? Best regards --- Robert GRASSO - System engineer
