Maybe, but more likely the problem is that you actually have 20GB free,
and maybe it needs 20.2 or something.
It's too bad it checks for total remaining space available. That
partition already has a bunch of VPSes running on it. It'd be nice if
it could somehow (magically?) check to see how much space is already
being used by existing VPSes and treat it as available space. Or have
a flag to allow it to ignore testing for available space altogether.
Actually, if I have it only split for five VPSes, it still fails:
---
hera:~# vzsplit -n 5
WARNING: Recommended minimal sizeof /var/lib/vz partition is 20Gb!
WARNING: /var/lib/vz partition do not have space required for 5 VPS
---
Or even just one:
---
hera:~# vzsplit -n 1
WARNING: Recommended minimal sizeof /var/lib/vz partition is 20Gb!
WARNING: /var/lib/vz partition do not have space required for 1 VPS
---
And for fun, 100 VPSes:
---
hera:~# vzsplit -n 100
WARNING: Recommended minimal sizeof /var/lib/vz partition is 20Gb!
WARNING: /var/lib/vz partition do not have space required for 100 VPS
---
Why does it need to be 20GB for a single VPS?
I just cleared out some space now. Here's what my partitions look like now:
---
hera:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdc1 4.7G 1.3G 3.5G 27% /
/dev/sdc3 28G 6.7G 22G 24% /var/lib/vz
hera:~# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdc1 4883556 1305704 3577852 27% /
/dev/sdc3 29309692 6930080 22379612 24% /var/lib/vz
---
Even though I've got 22GB available, it still claims I don't have 20GB
available same like before:
---
hera:~# vzsplit -n 20
WARNING: Recommended minimal sizeof /var/lib/vz partition is 20Gb!
WARNING: /var/lib/vz partition do not have space required for 20 VPS
---
In case it's useful, here's another strace:
---
