kernel error or hardware?

Hello people.

I have installed yesterday openvz, migrated a physical server to a vps and after a lot of help from the openvz
developers, I got it working excellent.

Today when I try to access the machine, it wasn't reachable in any way (remotely). What is seemed to be was
some fs problem, since when I tried to boot it, it always asked to run fsck, and it was telling all the time
there was problems with the partition /vz, among other things I will describe,

So well, I had to do like 20 server reboots, and in every reboot fsck started. After some time, it started
notmally, and everything working properly again.

I then started looking for logs, and found a lot of errors and strange (to me atleast) messages.

Googling some errors, in some cases there was some problem within the kernel, and in other cases there was a
hardware problem. That's what I coulnd't determine.

I am using 150GB sata disks, with a celeron processor 2.5 ghz, and 512 ram.

I will post my VPS config (the one I modified) and following all those strange log error messages. If anyone
has any idea about what could happened, it will be very appreciated.

Thanks in advance

kernel error or hardware?

Hi

          I'm not the biggest expert, but it looks like your hdd lost
connection with controller, which led to broken ext3 journal.

kernel error or hardware?

Thanks for your reply Aistis; do you think this is a hdd failure? It just happened again today, and I am going
to reproduce the same install on another server.

What do you think?

Thanks a lot

[how-to] allocating disk quota / memory / cpu

Hi all,
 I am a bit confused after reading all stuff & forums about allocating ram / cpu and disk space for VPS's. Could
somebody please write down these commands with examples?

 Example of a scenario:
 VPSID: 100
 CPU: 101 MHZ
 RAM: 102 MB Ram
 HDD: 103 MB disk space

 Also, can we allocate resources for VPS's, over than host machine has? 

 Example of scenerio:

 HOST
 CPU: 1000 MHZ
 RAM: 1001 MB
 HDD: 1003 MB

 VPS 1
 CPU: 1000 MHZ
 RAM: 600 MB
 HDD: 800 MB

 VPS 2
 CPU: 1000 MHZ
 RAM: 600 MB
 HDD: 800 MB

 Is this possible?

Problem with OpenVZ on Fedora Core 5

Hello,

i've just installed the openvz packages for fedora core 5. When I tried 
to run  vzpkgcache -f fedora-core-5 I got this:
# vzpkgcache -f fedora-core-5
Creating cache for fedora-core-5-i386-default OS template
ERROR: Can't start VPS 100002

I ran this with strace -f to see what might be the cause and I came 
across this:
[pid 10368] open("/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE) 
= 0
[pid 10368] fstat64(0, {st_mode=S_IFREG|0644, st_size=54062576, ...}) = 0
[pid 10368] mmap2(NULL, 2097152, PROT_READ, MAP_PRIVATE, 0, 0) = 0xb7d3d000
[pid 10368] close(0)                    = 0
[pid 10368] ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfc45af8) = -1 
EBADF (Bad file descriptor)
[pid 10368] unlink("/vz/tmp/XX0dwVO")   = -1 EISDIR (Is a directory)
[pid 10368] open(".", O_RDONLY|O_LARGEFILE) = 0

[pid 10368] close(0)                    = 0

So something with ioctl() probably went wrong. Could this be because of 
the fedora core 5 kernel ? I've installed the fedora core 5 kernel from 
the openvz website and the vzctl and vzquota were complaining about 
missing vzkernel and vzkmod-quota but I've installed them with --nodeps 
(the vzquota module is there and was successfully loaded after "service 
vz start"). Also I've booted the openvz kernel:
# uname -r
2.6.16-1.2080_FC5.026test007

Fedora Core 5 x86_64 precreated cache

Hi All,

Does anyone have a downloadable precreated FC5 x86_64
cache. I'm basically starting do configure a new x86_64 box
and since I'm unable to execute the vzpkgcache on such
box I would like to have a precreated one !

Thanks in advance.

Roberto Fichera.

Problem with OpenVZ on Fedora Core 5

Hello,

which vzctl version do you have? try vzctl-3.0.0-2, as latest vzctl for 
i686 has one bug which leads to this err msg.
Will be updated today.

Thanks,
Kirill
