RE: [Vserver] Vserver rpm errors
Ditto here, both for source and i386 RPMs. Can't query then with -qp or anything. Using rpm-4.2-0.69 (RH9). They work fine on RH6.2 (rpm-4.0.2-6x). A quick Google search shows people having similar problems this year with packages in Cooker. Seems to have something to do with RPM 4.2. No details of how the problem was fixed on the cooker lists, just a promise that fixed RPMs were coming, so don't know what to do about it. I'll extract the sources using the RH6.2 vserver and compile a new i386 RPM for anyone who needs it, assuming Jack doesn't get a new one out soon.

try the following
cd /vservers.new
dump 0f - /vservers/ref | restore rf -
this makes a copy of your vserver 'ref' to /vservers.new
(you don't have to care about proc/dev/pts umounting,
but, as somebody already pointed out, you have to worry
about applications not able to start from an uncleanly
shut down state ... in this case you could do the following:
vserver ref stop
mount --bind /vservers.new/ref /vservers/ref
vserver ref start

RE: [Vserver] Red Hat kernels (NPTL)
OK thanks Enrico.
Fortunately there are only 2 RH9-included packages which require db4 -
libtabe ("Chinese lexicons library for xcin-2.5's bimsphone input method."
don't think I'll be needing that one) and XEmacs.
Should I be recompiling my glibc? It seems to be running alright at the
moment. Although I've got a fairly bare-bones install on the host server so
I wouldn't really know if there were problems in various apps.

db4 makes problems[1] (which causes e.g. subversion to fail). Only solution
is to recompile db4 (set 'nptlarchs' to 'noarch' on top of .spec-file).
I am using a recompiled glibc also (same method like db4) with vanilla
kernel and have not encountered any problems with other userspace
programs.

Yes the RH kernel's got NPTL, but I'm using RH9 with a vanilla kernel fine here. That's probably because I'm not using any threaded apps, and my main vserver is running RH6.2 (legacy). There aren't many standard apps that would be threaded, you'd be more talking Java/threaded Apache/etc, so NPTL is only an issue if you actually use threaded apps. Anyone know which standards apps threads? As to the O(1) scheduler well that doesn't really matter too much - it just means you'll get worse performance, everything should work fine without it. Herbert's got O(1) scheduler patches for 2.4 if you want it though. Also you could _possibly_ rip the RedHat NPTL patches out of their kernel SRPM and apply them to a vanilla 2.4.22 kernel. Looking at the spec file you'd need these patches: # threading backport and O(1) scheduler backport; # last because they need to # be ifarch'd and touch a lot of code Patch11000: linux-2.4.20-o1-sched+threading-backport.patch Patch11001: linux-2.4.20-noresched.patch Patch11002: linux-2.4.20-futex-debug.patch Patch11003: linux-2.4.20-softlockup.patch Patch11004: linux-2.4.20-ptrace.patch Patch11005: linux-2.4.22-security-nptl.patch Patch11006: linux-2.4.20-ntpl-signal-delivery-fix.patch Patch11030: linux-2.4.20-noscheduler.patch Patch11031: linux-2.4.20-ptrace-hammer.patch Patch11032: linux-2.4.22-security.patch Still, it would probably get ugly pretty quickly. Anyone up for porting the v1.0 vserver patch to a Red Hat kernel? There'd be lots of happy customers =) ...

It's a redhat-based/redhat-style distribution, so most things are quite similar to redhat (i.e. it uses rpms and the system layout is much the same).

If you copy a running system, you will get an inconsistent state. If you're running a web server, a proxy or some other read-only/caching service, you'll just lose some log entries, so this may be ok. vservers offering storage, mail or other r/w services should be stopped before moving them.

[Vserver] Copy a vserver to different partition?
I've been all over the wiki and web site looking for a solution but I'm
getting no place slowly.
We had a hard drive fail but was able to move the /vservers/* into a
working drive before replacing the bad drive. As this is a live system
I'd like to _not_ take the server down and do another copy t othe new
partition. I need to copy all the vservers (or one at a time) in
/vservers to /vserver.new so I can stop the vservers, change the mount
point, and restart them.
I tried Herbert's dump/restore suggestion (FAQs) but have no experience
with dump/restore (spoiled by bru at an early age :-) and couldn't figure
out why it was failing the restore? Well some of it could be I'm using an
older version of dump (dump -v => dump 0.4b28) or my understand of the
example is wrong.
I've tried both
dump 0zf /mnt/vbackup/ref.dump /vservers/ref/
dump 0zf /mnt/vbackup/ref.dump /vservers/{ref}
the first works (but doesn't restore) and fails like this
{/vservers.new}# restore -tf /mnt/vbackup/ref.dump ./ref
Dump tape is compressed.
Dump date: Wed Nov 5 11:25:02 2003
Dumped from: the epoch

There have been a few threads on this list about using cp and other
options but I can't find them now. Vserver-copy doesn't seem to have the
ability (option) to copy from partition to partiotion on the same server.
I'm willing to damn the 'save space' option and worry about that later
just to get them onto the new drive/partition.
Any help for the slow-witted?
TIA,
Rod

[Vserver] Re: chroot and CAP_SYS_CHROOT broken ??
Hi, On Thu, Oct 30, 2003 at 08:57:01PM +0100, [EMAIL PROTECTED] was heard to remark: > > hmm, after --cap '!CAP_SYS_CHROOT', you should not be able > to perform chroot() at all ... and I don't see any reason > why the chroot() in you example should have worked ... Hmm. What was I thinking? Clearly, I should stop testing late at night... Thanks for the help, though ... I was exploring using some of the vserver features without going "all the way" and using vservers. To do this, it's become clear to me that a set of tools that are easier to use/better than setpcap/getpcap are needed. Is there anyone working on such a thing? p.s. I have ppc64 patches; they are essentially identical to the other arch patches. Should I send them to you directly? --linas -- pub 1024D/01045933 2001-02-01 Linas Vepstas (Labas!) <[EMAIL PROTECTED]> PGP Key fingerprint = 8305 2521 6000 0B5E 8984 3F54 64A9 9A82 0104 5933 ___ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver

I could track down the problem to the fcntl64 syscall.
Strace output:
10:36:19 fcntl64(3, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=0,
len=0}
I attached a small perl script to reproduce this.
After that syscall the process goes to state D and if the lock would be
granted by the nfs server (if it is not locked already), there is no further
access possible to that nfs share, even umount -f does not work.
As far as I can tell, if the file is already locked by another process, it
just waits, as I would expect.

(sorry I forgot to include the versions):
Both 2.4.22, same .config, just the vserver patch is different.
Host is debian stable/woody, vserver is debian unstable/sid.
