Hey all,
Ok, so I've been having some trouble for a while with an EC2 instance
running CentOS 5.11 with a disk volume reporting 100% usage. Root is on an
EBS volume.
So I've tried the whole 'du -sk | sort -nr | head -10' routine all around
this volume getting rid of files. At first I was getting rid of about 50MB
of files. Yet the volume remains at 100% capacity.
Thinking that maybe the OS was just not letting go of the inodes for the
files on the disk, I attempted rebooting the instance. After logging in
again I did a df -h / on the root volume. And look! Still at 100% capcity
used. Grrr....
Ok so I then did a du -h on the /var/www directory, which was mounted on
the root volume. And saw that it was gobbling up 190MB of disk space.
So then I reasoned that I could create an EBS volume, rsync the data there,
blow away the contents of /var/www/* and then mount the EBS volume on the
/var/www directory. So I went through that exercise and lo and behold.
Still at 100% capacity. Rebooted the instance again. Logged in and.. still
at 100% capacity.
Here's how the volumes are looking now.
[root@ops:~] #df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 9.3G 49M 100% /
none 312M 0 312M 0% /dev/shm
/dev/sdi 148G 116G 25G 83% /backup/tapes
/dev/sdh 9.9G 385M 9.0G 5% /backup/tapes/bacula-restores
/dev/sdf 9.9G 2.1G 7.4G 22% /var/lib/mysql
fuse 256T 0 256T 0% /backup/mysql
fuse 256T 0 256T 0% /backup/svn
/dev/sdg 197G 377M 187G 1% /var/www
There are some really important functions I need this volume to perform
that it simply can't because the root volume is at 100% capacity. Like the
fact that neither mysql nor my backup program - bacula will even think of
starting up and functioning!
I'm at a loss to explain how I can delete 190MB worth of data, reboot the
instance and still be at 100% usage.
I'm at my wits end over this. Can someone please offer some advice on how
to solve this problem?
Thanks
Tim
