[Vserver] Samba and Vserver Best Practices
I'm setting up a host server and several vservers that developers in my organization will use to test bug fixes of our software. They will occasionally need access to certain directories on the vservers to check logs, etc. For convenience sake samba shares to the needed directories would be the thing to have. Is the best practice to set up samba on the host server and share directories within the /vservers/$SERVERNAME/path/to/log/dir or set up samba w/in the vserver itself and share it that way? ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
[Vserver] /dev/null
I'm using some vservers on RedHat 7.3 w/ kernel 2.4.24-vs1.26. I'm running apache and jboss on the vservers. I've been patching our custom ears, jars etc. Now all of a sudden the /dev/null devices on two of the vservers are showing up as rw-r--r-- instead of crw-rw-rw- . I noticed this when switching to a non-root user and bash reports: bash: /dev/null: Permission denied And when I try to start jboss I get: run.sh: /dev/null: Permission denied jboss never starts. Any ideas before I go monkeying around and try to recreate the device. Can I even recreate a device in a vserver? Charles H.

[Vserver] Kernel Patching Questions
1. include/linux/sys.h: vanilla 2.4.21 had #define NR_syscalls 270 but RHEL 2.4.21 has #define NR_syscalls 271 So should I make NR_syscalls now 274 or 275? 2. include/linux/sched.h: any ideas what to do with this hunk (following)? There's nothing even vaguely like it that I can see. *** *** 956,961 out_of_line_bug(); write_lock_irq(tasklist_lock); nr_threads--; unhash_pid(p); REMOVE_LINKS(p); list_del(p-thread_group); --- 968,975 out_of_line_bug(); write_lock_irq(tasklist_lock); nr_threads--; + if (p-s_info) + p-s_info-nr_threads--; unhash_pid(p); REMOVE_LINKS(p); list_del(p-thread_group); 3. forget_original_parent in exit.c seems to have changed completely - looks like the vanilla 2.4.21 used a read_lock while the RH one uses list_for_each_safe which I assume locks as it goes. But that means there's nowhere left to put the additional bit from the vserver patch (not sure what it does exactly, it tries to find a new parent for vchild_reaper I think). Boy I'm tired, that's way too much kernel hacking in one day for me. 10 rejects down, 20 to go... Any help appreciated. BTW, there are 266 patches applied inside the RHEL3 kernel SRPM... Grr.

It's rather malnourished at the moment (no it's not as simple as it might seem!), but remember that, unlike at the zoo, you're welcome to feed it: http://www.linux-vserver.org/index.php?page=Step-by-Step+Guide Also I've added a News section to the main page.

Please add details of how _you_ use vservers - VDS/security/backup/coffee/whatever: http://www.linux-vserver.org/index.php?page=Examples This will hopefully get people excited about the various possibilities. In terms of site organisation I think we should aim towards a 3-way split: 1. Users - New 2. - Current 3. Developers New users need: * Project overview (quick introduction) * Examples of vservers in action * Step-by-Step VServer Setup Guide (goes through everything required to get a functioning vserver) * FAQ * Links to getting further help Users need: * Release news, changelogs, download links * FAQ * Links/documentation on extra features like per-context quota disk limits * Man pages for the tools (or not?) * Explanation of the vserver patch (maybe this is for developers) Developers need: (everything that users need, plus:) * Their own area to discuss stuff (Syscall switch, todo lists). * I don't know, I'm not a developer! Most of these elements are coming together. We need to (1) fill out the current docs, then (2) fit everything together nice and cleanly. That's enough for tonight, goodnight!

Correct... that's assuming redhat9 uses NPTL, I'm pretty sure it does but somebody correct me if I'm wrong... 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.

hi matthew, thanks for your hints!! i will try it! cheers, charles - Original Message - Ah, I see. Well, you probably want your /etc files to be manageable on a per vserver basis, so that'd be bad to link. Also, /var/log/* and probably some or all of /var/lib should not be linked. I think /usr is an excellent candidate for linking. There are others on this list that have already tackled this issue so it shouldn't be hard to get a conclusive answer. Additionally, the linuxconf vserver tools can automate this work, so it should be possible to simply look at that code to see what is and isn't linked. This would probably be a good reference item for the wiki. If/when we get a solid answer, we should probably post it there.

However, regarding this issue, if you do cp -al file1 file2 (that's lower case A L ) it simply makes a hardlink from file1 to the other. That way, you can make links from the comfort of your copy command. Matthew Nuzum | ISPs: Make $200 - $5,000 per referral by www.followers.net | recomending Elite CMS to your customers!
