Here is one of my ext4 filesystems, which uses 2x more space as it should: # df -h /srv Filesystem Size Used Avail Use% Mounted on /dev/xvdf 194G 134G 51G 73% /srv # du -sh /srv/ 60G /srv/ # lsof -n|grep /srv # So df says 134 GB is used, while du says 60 GB is used. No removed but used files, according to lsof. How do I best debug what happened to ~70 GB? This is EC2 kernel, nothing interesting in dmesg: # uname -a Linux ec2.agenteimovel.com.br 3.0.0-12-virtual #20-Ubuntu SMP Fri Oct 7 18:19:02 UTC 2011 x86_64 GNU/Linux -- Tomasz Chmielewski http://www.ptraveler.com -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
