[arch-general] VPS can't access after update filesystem?
Hi, I rent a VPS from a not-so-famous provider, and they use XEN. After I updated my system on Jun 10 (I update my system every Sundays), My VPS seems dead. I can't ssh to it, I can't ping to it, I can't do anything to it. I don't get any error message from the SolusVM control panel---it says: 'online' The service of my provider is not that good, so I really don't get any useful info from them. I re-installed the OS (they provide Archlinux-2011.7-x86-64), and the VPS is accessible again. But after I update that new system, The VPS stopped working, same as above. All I know is that update includes 'filesystem' package. So I suspect the updated 'filesystem' package is the culprit. Maybe the 'init' process encountered some errors. No error log (probably won't get anything anyway), so... Again, VPS provider info: Supervisor (is that right?): XEN Control panel: SolusVM System: Archlinux-2011.7-x86-64 Regards.
hmmm... the second time you updated, did you have any packages installed? (\_ /) copy the bunny to your profile (0.o ) to help him achieve world domination. (> <) come join the dark side. /_|_\ (we have cookies.) On Tue, Jun 12, 2012 at 6:34 PM, Bill Sun <cap.sensitive@gmail.com> wrote:

Did you follow the instructions in the news item? One thing to try would be "pacman -Syu --ignore filesystem", reboot and check if your server still works, and only then upgrade filesestem. At least that will tell you what the culprit is. -t

I updated 'pacman' first, then force updated 'filesystem', and reboot. VPS worked fine. After a system update (pacman -Syu), the VPS is dead, again.

Yes, usually vps hosts using solusvm will have serial console access. -- --Szu-Han Chen (sjchen.com) O< ascii ribbon campaign - stop html mail - www.asciiribbon.org
so? why don't you access it my serial? PS: serial console? WTF? 50 years ago??? (\_ /) copy the bunny to your profile (0.o ) to help him achieve world domination. (> <) come join the dark side. /_|_\ (we have cookies.) On Tue, Jun 12, 2012 at 7:05 PM, Szu-Han Chen <sjchen@sjchen.com> wrote:

And still demanded by many on servers. With suns you can access bios over serial. You need networked KVM for that on PCs. You can set screen output from bootup onwards to serial rather than VGA. Granted the serial mode doesn't help untill he's up and running again but he could take the opportunity to switch provider if possible. arpnetworks.com solution is pretty cool. I'd use it if I had more faith in VPS security over bare metal.
another format maybe? but make sure that you have serial access before upgrading! provider: edis.at cheapest VPS ever (i just love their support) id you have money to go for a dedi, then go for it and don't even think about VPS PS: i think that KVM (my host has) is better than XEN. Also you have VNC access (even BIOS) :) (\_ /) copy the bunny to your profile (0.o ) to help him achieve world domination. (> <) come join the dark side. /_|_\ (we have cookies.)

I got the error message: ERROR: device '/dev/xvda1' not found. Skipping fsck. ERROR: Unable to find root device '/dev/xvda1'. You are being dropped to a recovery shell Type 'exit' to try and continue booting sh: can't access tty; job control turned off Regards

Looks like your initramfs got borked when you updated the kernel. Make sure to read the recent news article [1] about systemd-tools replacing udev (and maybe the last question in the troubleshooting section of the pacman wiki page [2]), and be sure to run this after updating (but before rebooting): # mkinitcpio -p linux [1] http://www.archlinux.org/news/systemd-tools-replaces-udev/ [2] https://wiki.archlinux.org/index.php/Pacman#Troubleshooting -- Kevin Arthur

Problem solved. Thanks.
Problem solved. Thanks. I probably should put a more comprehensive solution here. I consulted the 'Xen' [1] entry in archwiki, and add: MODULES="xen-blkfront xen-fbfront xenfs xen-netfront xen-kbdfront" to '/etc/mkinitcpio.conf'
