Subject: something's using space, can't figure out what - how to debug?
Date: Wed, 10 Apr 2013 19:56:06 +0900 [thread overview]
Message-ID: <20130410195606.22a9eff3@wpkg.org> (raw)
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
