Conf file corruption [message #11571]

Has anyone here seen their conf files get corrupted? I am finding that
when I change the value of a parameter using vzctl set while the VPS is
running, that a big chunk from the middle of my conf file gets duplicated
near the bottom of the file.

This could be because I added many lines of comments to the file and it's
bigger than the distributed files. I think it also happens when I use
vzcfgvalidate in interactive mode.

Has anyone else seen this?

Yes, I'd seen some binary data after end of my config files - multiple
times.

Well... I was lazy to report that, I only removed that in vim. ;)

have you used vzcfgvalidate as well or vzctl only?

Thanks,

I'm mainly using vzctl or direct file editation in vim, in past I also
few times used vzcfgvalidate, but I'm unable to recall when exactly and
in which order.

That's reason why I didn't report this, I don't known how to reproduce
problem and it didn't seam be critical as those binary data were always
at end of config file and VE was able start/stop correctly.

Hello, can you attach here this unusual config file and tell us how to
reproduce the problem?

Thank you,
Vasily.

Well in my case, there is a little binary data added but also chunks of the
text seem repeated. I just did something very simple:

vzcfg create 5000 --config vps.b1

I attached to this email both the ve-vps.b1.conf-sample and also the
resulting 5000.conf file. The 5000.conf file is corrupted. I didn't even
start the VPS.

I am running on Debian Etch AMD64 with a prebuilt 2.6.18 kernel. I'll look
for other ways to cause this to happen, but if anyone has any questions in
the mean time just let me know.

is it 100% reproducable on your machine?
can you please also provide vzctl version you use:
# vzctl --version

I've create a bug http://bugzilla.openvz.org/show_bug.cgi?id=515
will try to reproduce and analyze.

if you have any other sample/examples of how to trigger this,
please add this info to the bug.

Thanks a lot,
Kirill

I've also observed this issue, under FC5 on intel x86_64 smp (duo-
core xeon dual processor) hardware, about 4 months ago (sorry, I
can't provide the versions I was testing then, 2.6.16_testing kernel
and some version of vzctl). I only observed the binary 'fluff' at
the very end of the .conf file on that one occasion, I simply vi'd
the file and corrected it.

Guys, one more question, have you used precompiled vzctl or compile it
by your self?

Thanks.

I used the vzctl installed as a Debian package from ststs.org. I have not
compiled any of the OpenVZ code at all.

I had installed vzctl via the openvz yum repo at that time.
