RE: [Vserver] stalled vserver guest nfs mounts
Here are some notes on nfs I made when playing with it. #I re-mount this filesystem manually without a vserver restart from the root/host sudo vnamespace -e 100 mount -t nfs calnfs01.fglcorporate.net:/nfs_unix_data /vservers/unixdev1/unix_data #I can unmount this filesystem manually without a vserver restart from the root/host sudo vnamespace -e 100 umount /vservers/unixdev1/unix_data Note that 100 is the context of the vserver. It may look a little screwy when doing manual mounts (df -h) but it works. When the vserver is restarted all looks right again. Hope it helps.

RE: [Vserver] [EMAIL PROTECTED]
Yes as Herbert notes from your output: Use dietlibc: no (you have been
warned)
I think you may have overlooked the following line from the crux install
notes: sudo prt-get install dietlibc
I believe you need to use dietlibc, I had troubles without it. Herbert
suggested I try it. All worked fine after. If you search the ml/irc
archives at the very least you'll find my issues.
I have included a snippet below.
Not running make install-distribution did not seem to cause me any
issues. But it is prob worthwhile running.

Herbert thanks for your help.
Issue: Unable to stop vserver, everything else appears to work
fine.
Issue was resolved when dietlibc was installed and tools
recompiled
EG:
Installed dietlibc
cd /path/to/vserver/src/util-vserver-0.30.208
make uninstall
make clean
./configure
make
make install
Note: allowed ./configure to autodetect dietlibc
from config.log
...
configure:9473: checking whether to enable dietlibc
configure:9533: result: yes (autodetected, 0.29)
...
Thanks,

Thanks for answering my question. Regarding the user-space command, ah, maybe I did not think it through when I wrote that. But my concern is that once you hard copy a guest server, then you still need to copy/create /etc/vservers/newtest, where newtest is the name of the newly copied server /vservers/newtest.Basically, by copying by hand, users have to take of these steps???Or should you suggest to use vserver-copy, then delete /vservers/newtest, then hard-copy. Because my guess is that vserver-copy would take care some of the works regarding configuration files. I have troubles carrying out some of the steps because I just don't know which of which is legacy or new. I have tried to absord as much infor as possible but I am sure I might forget some of the readings.Could you suggest or point to document(s) that describe(s) correct ways of doing these things?Thanks for sharing your knowledge.Steven.

hmm, looks like you are missing one of the
context capabilities for secure mount ...
#define VXC_SECURE_MOUNT0x0001
#define VXC_SECURE_REMOUNT 0x0002
#define VXC_BINARY_MOUNT0x0004
I thought I would be fine with it that way but it turns out it is a
bigger issue than I thought. Any suggestions on how to umount the NFS
filesystem?
unmounting on the host should work quite fine ...
best,
Herbert
I have access to host and vserver.
thanks

RE: [Vserver] unable to stop the vserver after upgrade
Herbert thanks for your help.
Issue: Unable to stop vserver, everything else appears to work fine.
Issue was resolved when dietlibc was installed and tools recompiled
EG:
Installed dietlibc
cd /path/to/vserver/src/util-vserver-0.30.208
make uninstall
make clean
./configure
make
make install
Note: allowed ./configure to autodetect dietlibc
from config.log
...
configure:9473: checking whether to enable dietlibc
configure:9533: result: yes (autodetected, 0.29)
...
Thanks,

Booted into upgraded Kernel with vserver patch

RE: [Vserver] a couple of beginner questions
If I add the following to the vserver fstab file and restart vserver.
cat /etc/fstab
/dev/root / ext3 rw 0 0
Then df command works for the vserver partition
df -h
FilesystemSize Used Avail Use% Mounted on
/dev/root 22G 2.5G 18G 13% /
I have not gotten any other entries to work
But doing the above breaks the df command on the host server.
df -h
FilesystemSize Used Avail Use% Mounted on
/dev/hdv1 198M 23M 166M 12% /
none 2.0G 33M 1.9G 2% /tmp
any suggestions on how this should be done?

no, that's not normal, but I suspect you are missing some

on that)
Other commands like top, ps, du all work fine.

RE: [Vserver] a couple of beginner questions
Herbert,
I'm sorry, perhaps I've gotten off track. This goes back to the df command not
working in the vserver.
:df
df: cannot read table of mounted filesystems
you mentioned the following to me and I started chasing that rabbit.
no, that's not normal, but I suspect you are missing some
file (maybe /etc/mtab or so) which is used by the df
tool (using strace -fF on the df might shed some light
on that)
I was thinking that I needed an entry in /etc/fstab on the vserver to get df to
work.
My strace is in a previous posting.
thanks

hope someone can help me with.
