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@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
