VPS Hard Disk Space Discrepancy

[Mark Phillips]

I had 1 GB of swap.

It seems Ohava realized they had made a mistake when they provisioned a
large group of nodes in October and (1) rebuilt my node and (2) offered to
upgrade everyone to 40 GB of disk space in a public announcement on their
web site.. My node was rebuilt last night and df now shows

Filesystem                   Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-root   19G  1.8G   16G  10% /
none                         4.0K     0  4.0K   0% /sys/fs/cgroup
udev                         235M  4.0K  235M   1% /dev
tmpfs                         50M  368K   49M   1% /run
none                         5.0M     0  5.0M   0% /run/lock
none                         246M     0  246M   0% /run/shm
none                         100M     0  100M   0% /run/user
/dev/vda1                    236M   68M  156M  31% /boot

and 1 GB of swap, according to top:

top - 07:36:27 up  8:30,  1 user,  load average: 0.00, 0.01, 0.05
Tasks:  72 total,   1 running,  71 sleeping,   0 stopped,   0 zombie
%Cpu(s):  0.0 us,  0.0 sy,  0.0 ni,100.0 id,  0.0 wa,  0.0 hi,  0.0 si,
0.0 st
KiB Mem:    501804 total,   484280 used,    17524 free,    53080 buffers
KiB Swap:  1044476 total,     3472 used,  1041004 free.   353988 cached Mem

The memory is short (sb 512 MB), but that is a disagreement over 1 KB -
1,000 versus 1 KB = 1,024, which I won't win.

So, it seems like an "honest" mistake on their part, unless I am missing
something.

Thanks!
