Re: [CentOS-virt] Virt-install
Version number. It's 0.5.3-10. Current version on lfarkas's repository is 0.7.0-4. I use it (0.7.0) for a month now, I think, and have not seen any issues so far. I also use kvm-84 from his repository and I have mot seen any problems except I am not able to connect with virtsh to qemu:///system, from root, just qemu:///test. All clients are CentOS 5.3 with kernel 2.6.18-128.1.6, but I must keep virtual host (CentOS 5.3) on 2.6.18-92.1.22 kernel because of issues with MB with AMD chipset (I was going to report this but never got the time to prepare all the info needed).

Re: [CentOS-virt] Machine freeze
Hey, I'm wondering if it is possible that your problem is related to mine. Earlier today I had to restart one of our domUs on one of our systems. I used xm shutdown instead of xm destroy and then did xm list to determine if the domU had shutdown or not. Upon issuing xm list a second time, the entire server crashed and rebooted. I've checked the logs and have yet to find anything. I've attached a transcript of the commands as I executed them on the server. The system is running CentOS 5.3 x64 w/Xen (kernel 2.6.18-128.1.6.el5xen). Any thoughts? Thanks, Matt -- Mathew S.

Re: [CentOS-virt] Machine freeze
Yeah, the Dom0 should have plenty of memory left since only 2-3 GB of memory is being used out of 12 GB installed. The out of memory messages were from the domU that I xm consoled into prior to shutting down that particular VM because it was out of memory. Matt -- Mathew S.

[CentOS] Rsync/SSH automation problem?
Hi All, I have a win2k3 server that its backing up to a CentOS 5.3 server. On the Win2k3 machine I plan to have rsync back up nightly to the CentOS server through ssh. The command I am using is as follows: rsync -vrPtz -e ssh myu...@myserver:/remote/backup/folder/ /local/backup/folder/ This all works great for the inital test except its prompts me for a password for myuser (as you would except) but how can I embed the password for ssh into the command line? Or can I not? Is the following some how possible: rsync -vrPtz -e ssh myu...@myserver mypassword /remote/backup/folder/ /local/backup/folder/ Or something like that? I can't find anything that says it is possible so its probably isn't but I know that some of you out there have far superior searching skills than I or hopefully, you might already know? Assuming this isn't possible as I've got that gut feeling it won't be, does anyone else have a better idea? BTW; Rsync in running on the windows box through cygwin in case you wondered or hadn't guessed ;) Many thanks, James ;) -BEGIN GEEK CODE BLOCK- Version: 3.1 GIT/MU/U dpu s: a-- C++$ U+ L++ B- P+ E?

I hadn't correctly enabled WOL on the NIC card: I don't know about your Dell, but on my HP ML110 servers, I had to add a line to ifcfg-eth0 to make ethtool tell the LAN port to enable the wake-on-lan function: ETHTOOL_OPTS=wol g You will need to take the interface down and up after adding the line. Cheers Tony Also the other problem was I was using a dual Gigabit NIC, in particular I was using the 2nd port, but it turns out WOL only works on the first port!

[CentOS] GFS and Small Files
Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls to be printed out, or in certain cases, 20minutes or so) This is completely true especially in directories containing large number of small files (e.g 9+ of 1-4kb files). The thing is, most of system users are generating these small files frequently as part of their workflow. We tried emulating the same scenario (9+ of small files) on a ext3 partition and it gives almost the same result. I believe most of the CLVM/GFS settings done are using the defaults parameters. Additionally, we would prefer to stick to GFS (or at least ext3) as it is part of CentOS / RHEL distribution rather than changing into other small-files 'friendly' filesystems (such as XFS, ReiserFS). I'm exploring whether is there anyway we can tune the GFS parameters to make the system more responsive? I have read that we can apply 'dir_index' option to ext3 partition to speedup things, but I'm not so sure about GFS.

Thanks for your input, unfortunately the servers will be communicating via the inter-web-net-spagetthi.

Re: [CentOS] kickstart problems...
From: John Doe jd...@yahoo.com 4. OT: fs corruption ont he USB keys... I copy the iso file on the key (no error message), then compare it to the original and some random differences appear. I have corruption problems with both the i386 (3.7GB) and x86_64 (4.2GB) DVD iso files. But I tried the CDROM iso files instead and I don't have any corruption (even though they use almost the same disk space)... Looks like there is a big files problem.

Re: [CentOS] 5.3 on an EeePC??
Warren Young wrote: I think much of the hype about how great the Debian packaging system is came from the days before they adopted yum, so Debian fans could point to apt-get and say Isn't it great to be able to install packages from the net directly from the command line? Sure, once upon a time it was, but today, the main distinction I draw between the two sets of tools is that the Debian tools are more complex with no compensating benefit. (There are even some things the simpler Red Hattish tools can do that the Debian ones can't, easily. rpm -qa, for one.) rpm -qa typically just lists all of the packages on the system, the equivalent in debian is dpkg -l. I think much of the hype isn't really hype and mistakenly compares package formats deb vs rpm, and package managers apt-get/aptitude /dselect(shuder) vs yum. Building from source is pretty easy assuming you have src entries in apt's configuration: apt-get build-dep package name - installs all dependencies required for building apt-get source -b package name - downloads and extracts source code and compiles it It's more about the repositories themselves, the QA behind them, the integration of packages.

At least package counts Debian has more than 10x more packages than CentOS 5.2. My desktop at home has nearly 1900 packages installed. Also the debian package databases are in plain text format, while I'm sure it has happened I have never personally heard of someone suffering from package database corruption on debian(assuming they were running the 'stable' version). Such corruption reports seem somewhat common in the RPM world with the binary databases. Add to that the well tested ability to upgrade between minor and major version numbers time and time again. I don't have to hold my breath when I go from Debian 4.0 to 5.0, I can do it from remote without ever losing connectivity, I don't even have to reboot at the end I can continue running the older kernel if I want. Perhaps things have changed recently but last I heard there was no supported upgrade path to go from RHEL 4 to 5 (I'm sure it's possible but I don't believe it's supported). There are folks out there that have seamlessly upgraded debian from back in the 2.x days all the way to current, more than a decade of upgrades on one box. I have only gone a couple major revisions before I end up retiring the hardware and starting fresh myself. Since Ubuntu builds on Debian a similar number of packages are available for it though they don't go through as much QA in the universe and multiverse repositories, but do in many cases inherit the QA done by the Debian team. I've never really been fond of yum myself, though it is much better than what was there before(nothing, before rhn at least). I've been using RHEL/CentOS for about 6 years, Debian for about 11 years. I do prefer RHEL/CentOS for my work systems since I configure things on a larger scale and that requires quite a bit of customization, and I use Debian for all of my personal systems. These days I'm much more familiar with the internals of RHEL/CentOS than I am Debian anymore. I currently maintain roughly 100 SRPMS(results in roughly 465 binary RPMs) for my production environment (compile for CentOS 4/5 32,64 and noarch) which are distributed to the systems using cfengine depending on what the systems need. Don't get me wrong I really do like CentOS it has it's purpose, I just wanted to try to clarify what I view to be a misconception among folks who champion debs over RPM, it's much less due to the format of the packages themselves, or the package manager itself. If you feel comfortable going down paths that offer less support such as using 3rd party repos, performing non standard steps to do system upgrades etc then that's great. These days I prefer less wildcards in my life so I don't venture beyond the unsupported unless I really need to(folks may be able to determine this by my ratio of questions to (attempted) answers on this list). happy trails nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Not only sorting, but usually ls ends up trying to find out if the file is a directory, which uses a stat syscall for each of the files. This is always expensive on remote filesystems (e.g., NFS) and I would expect it to be also the case in GFS. Besides the -U option of ls, you might want to look at other options that would make ls not try to stat each file. I'm not sure exactly which of them, but one I can think of is disabling color (since color will trigger a stat to find if the file is a directory). In general, having directories with a huge number of files tends to be a bad idea, you will most likely have performance bottlenecks with specific filesystems or tools.

Here is what I am seeing now: User creates a new company file through QB (this is already fubar'ed): # ll -rw--- 1 Domain+jcasale DOMAIN+AD_Group 7647232 Apr 29 14:37 Company.QBW -rw-r--r-- 1 root DOMAIN+AD_Group 420 Apr 29 14:36 Company.QBW.ND -rw-r--r-- 1 Domain+jcasale DOMAIN+AD_Group 1114112 Apr 29 14:36 Company.QBW.TLG drwx-- 2 root root 16384 Apr 24 09:34 lost+found -rw-rw 1 root DOMAIN+AD_Group 300 Apr 24 10:17 qbdir.dat Now after working with the company in QB, this is what happens: # ll -rw--- 1 Domain+jcasale DOMAIN+AD_Group 7331840 Apr 29 14:37 Company.QBW -rw-r--r-- 1 root DOMAIN+AD_Group 420 Apr 29 14:37 Company.QBW.ND -rw--- 1 Domain+jcasale DOMAIN+AD_Group 1245184 Apr 29 14:37 Company.QBW.TLG drwx-- 2 root root 16384 Apr 24 09:34 lost+found -rw-rw 1 root DOMAIN+AD_Group 300 Apr 24 10:17 qbdir.dat What are my options to control this here? Edit init scripts for that daemon? I don't know what would happen if it doesn't run as root, but maybe as a user that has GID of DOMAIN+AD_Group?

They refer to FAM as the per the documentation. Question: Did QB give you documentation on how to set it under Linux? I was just about to post the same thing after I thought about it, as gamin operates on the files outside of Samba... They did provide a guide, but its weak and the setup from what I can see is not secure. They suggest: # chmod -R 775 /directory # chgrp -R groupname /directory [share_name] path = /directory comment = samba share for company files valid users = user1 user2 user3 public = no writable = yes printable = no create mask = 0765 Not sure why other gets anything? I don't even see how that cures the issues imposed? I think that continued access by the client works, it's just when they try to delete a company... The only thing I can think of is a cron job with a find excluding the lost+found performing a chmod/chown? That's just silly though. What a POS.

I would never suggest that anyone use Samba/Linux to host Quickbooks share unless they wanted to experience real heartburn. That said, I don't generally advocate 'force user/group' configuration on samba shares either unless there absolutely were no other way. I think Joseph is onto most of it with... chown root:DOMAIN\AD_Group /mnt/Intuit_Data/ chmod 2770 /mnt/Intuit_Data/ and I would add one more thing to the share definition... store dos attributes = yes inherit permissions = yes Which generally makes for happy workgroups on Samba if the share is mounted with user_acl which is generally the default for Red Hat/CentOS systems but I can't vouch for Quickbooks behavior.
