Hello list,
I having a problem to understand the output of du and df command :
[root@ftp ~]# df -h /opt/
Filesystem Size Used Avail Capacity Mounted on
/dev/xbd6 387G 342G 13G 96% /opt
[root@ftp ~]# du -sh /opt/
342G /opt/
But 387Go - 342Go not equal to 13Go ! Where's the available space ?
(same thing with df -k)
I have try a tunefs -m 1 /dev/xbd6, unmount, mount and nothing change
Is it the 8% reserved by FFS ?
See:
http://www.freebsd.org/doc/en/books/faq/disks.html#DU-VS-DF
Thank for the link, but in my case du and df are the same used output, and it's not an rm, I launch lsof and no process with a big file :-/
Regards,
Alain
