Server Reboots

[davidof]

Hi,

I noticed that my host was rebooted a few minutes ago but my VPS wasn't restarted automatically, is this usual?

yea we just did some reboots to fix some security flaws in the kernel that was operating. successfull however.

Reboots are not a problem it was that my VPS didn't get restarted automatically, is this normal or have I missed something?

Has anyone noticed strange things happening since the unannounced reboot? Are the clocks out of perfect sync maybe? I am having many problems with Roundcube session tickets.

Need to do a full investigation yet but I thought I would ask on the offchance.

clocks out of perfect sync maybe
Have you checked your clock?


having many problems
Can you be more specific?

Have you checked your clock?

I've been using your hardware clock, not bothering with my own NTP client, but I only mentioned clock as it seems roundcubes session tickets are based on them.

Can you be more specific?

At this point in time no. Sorry. I was just asking if anyone had seen strange things happen immediately the unannounced reboot was done.

It's probably a software beta related issue, but before digging in code for a day I want to check for any obvious things.

Did you have a strong reason for not running NTP? It is generally considered a good idea to have accurate times in log files if you are following up a hacking attack. But then does anyone bother following through hack attacks these days... let alone spending the best part of a year full time doing so.

Having said all that I'm not exactly sure what the relationship is between the RapidVPS clock, the Virtuoso clock and the hardware clock.

What I know is that my desktop system updates from servers every 6 hrs. and only drifts 1.4 seconds per day. When I check my VPS time against clock seconds on my desktop, it's always spot-on; and that's without ntp on the vps.

My quick guess has been that the vps guests are controlled by the host which itself takes care to be on time.

Big Thanks! to Rapid for this.

Also, ....
"hwclock is unable to get I/O port access: the iopl(3) call failed."

Hi, you can't adjust the system time. However, we keep it sync'd and you can change the timezone. The end result is enough control for whatever you need to do.

yeah..

my first month on rapidvps was not good. 3 - 4 times down, approx 2 hours or more total downtime(according to website base tracking).. :(
hope this month is better.

y3 - 4 times down, approx 2 hours or more total downtime

My logs didn't show that much downtime, nowhere near it in fact.

FWIW Here are the 3 nines calculations on exactly 2 hours downtime in September.

Downtime = 2 hours x 3600 seconds = 7200
Uptime = (29 days x 86,400 seconds) + (22 hours x 3600 seconds) = 2,584,800

7200 / 2584800 = 0.002786
1 - .002786 = 0.997321
0.99721 * 100 = 99.73% uptime

Exactly 2 hours in September is just under Rapid's three nines guarantee as there were no "well planned and announced" outages. So if your records are solid and verifiable maybe approach billing for a refund under SLA.
