My migration strategy at this time is to 1. Present a new LUN from the new SAN to all machines. 2. Make a PV with the new LUN. 3. Add it to the existing VG. 4. Use pvmove to move all the data from one PV to another. 5. Once the old LUN is empty, complete a pvresize to remove the old LUN. This all seems sound but looking for advice, specifically around the fact that the VG/PV data is being used by a number of machines/servers and the LV's are active on a number of different nodes. All the documentation/examples I can find assume a disk in a server, not a LUN on a SAN being shared by a number of servers. Any advice is appreciated. Cannot help with the SAN question other than to say that you are just adding another PV block device to a VG and LVM shouldn't care. My comment is on step 5. You want to vgreduce -a VG to remove empty PVs (assuming only the old one is empty) followed by pvremove PV to remove the old PV.

Currently, the only guest I have running the netkvm driver is winxp, because e1000 was not a trivial option. Before you ask, could never get win7 to boot using the viostor (virtio blk) drivers, but could get winxp and vista to boot on them.

Since I don't have a dedicated backup server, I did not want to mess up the existing apache configurations... You really don't spend any time in the web interface which is the only thing affected by this. And it is fast enough when run as a normal CGI anyway. Try it without mod_perl. You'd also have the option of running backuppc as apache, but that is less secure if other web admins have access to the machine. As a side note, the epel BackupPC package does NOT use mod_perl by default and the centos-testing package does use mod_perl by default. I run the centos-testing package (with mod_perl) and the epel package with and without mod_perl usage and see no practical advantage of using BackupPC with mod_perl in terms of time/cycle usage. So just use the stock epel package and you don't need to modify apache. Steve ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I have looked around and found a spot in IE to 'import' a cert of some kind...and this would seem like the way to make it work. I am unsure exactly what I am supposed to copy or run on the server to then save to my home computer to then add to the 'import' part. For sendmail I made a sendmail.pem and dovecot already came installed with its cert. It is annoying to have the warnings everytime I open outlook up and if anyone has experience with this stuff I would not mind a quick helping hand. Thanks all. Bob What warnings are you getting? You'll probably need to generate your own cert for dovecot too. The dovecot cert that ships with the package is for imap.example.com, so you'll probably get a warning that the cert doesn't match the host, and it also expired in Jan 2009 so you might get a warning for that too. If you generate your own cert, be sure the cert matches your FQ hostname. The other common warning is for an untrusted or self-signed cert, which can normally be overcome by importing the cert the first time. SSL/TLS for Dovecot is covered in the Wiki here: http://wiki.centos.org/HowTos/postfix_sasl#head-67159b2747e8ff10df5bf5da41d4f21a245afd7f I'll leave it for a sendmail user to advise you for that :) Adding to NedSlider's comments, you can also create your own Certificate Authority for signing your local certs and then clients can import your CA cert as a trusted authority. After that, any local cert you create and sign will be recognized as trusted by the client systems. It's surprisingly easy to do. The steps are nicely addressed in Apache Security (O'Reilly) by I. Ristic: Chapter 4, Apache and SSL pp.86-93 and Setting up a Certificate Authority pp. 93-99. They leave little to your imagination. And as NedSlider pointed out, be sure the host name on the cert. matches the actual host name. Outlook/OE are very unforgiving on that point.

So each vendor has its own WDS implementation (MIT's OnePC implements part of draft 1 of 802.11s). Of course there are devices out there that are referred to as wireless bridges (Linksys WRT54g is one) that act as a client and bridges an ethernet as a single client to the AP. Note that a wireless bridge is NOT an AP. Of course there are probably devices out there that can be configured either way Note, I work on the 802.11 standards and know them well, but I don't know of all the flavors of implementations out in the wild. At least when running the Tomato Firmware, the Linksys WRT54GL (L = linux) and WRT54G versions 4 and earlier (also linux-based) run WDS as hosts/clients very effectively. I run several GLs as access points across my lan with 0-2 more as WDS clients as needed. As a side note, Tomato Firmware allows you to adjust transmitter power up to 6 times the normal level and that has let me go through some very think brick walls to pick up remote network cameras. I should point out that both the host (access point) and client need to be WRT54G/L routers for the above scenarios to work. As RM said, WDS is vendor dependent.

If so, is there any simple way of preventing this? Not sure I understand the question, but I assume you are talking about backing up a remote system that has a nfs mount. Have not tried it, but would guess that the answer is Yes It Could. Using the rsync or rsyncd modes, you have the options to include and/or exclude whatever you want. Very simple to do. 2. I have seen it suggested that it is not a good idea to backup onto a partition on the same drive as the BackupPC server? Is that true? If so, is a partition on a separate drive on the same machine also bad? Sidestepping your question a little, are you planning to Not use some form of redundant storage? Given that you are making backups, single drive or nonredundant storage would be a bad idea. In general, it is true that using a storage system for data/files physically separate from the os/utilities is typically faster, but that does not sound like the gist of your question. What I do is to mount a logical volume at the storage location (/var/lib/backuppc) so that it can grow or be otherwise modified as needed. If the problem you expect is congestion, then you can limit the number of concurrent backups to less than the default of 4 (see MaxBackups and MaxUserBackups). I find that even modest single core systems can handle 1 backup without a lot of trouble. As a first approximation, start up a manual rsync of something big (e.g., /usr, iso image, etc.) from the remote system and see how that impacts the proposed BackupPC server. Once the BackupPC server is put into service, it is easy to figure out what the number should be. HTH Steve ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Searching the 3800+ and knowing it is 65 watts (EE) shows either an F2 or F3. Likewise, the 4850e is a G2. Checking the cpuinfo on systems using a 4850e (G2) and a 4600+ EE (F2) both give cpu family: 15, so they have included the Gs in the excluded group, too.

Re: [CentOS] Questions on cpu frequency scaling AMD vs. Intel

Is there anything I can do about that? Where could I check whether this CPU should be supported in full and frequency scaling working? The cpuspeed changelog may be relevant: [quote] * Thu Mar 06 2008 Jarod Wilson [EMAIL PROTECTED] - Disable freq scaling by default on AMD rev F and earlier cpus when running xen, due to clock instability (#435321) [/quote] I didn't look up your cpu, but I think it's a revision F. Also, thanks for the /etc/sysconfig/cpuspeed ondemand tip. It seemed counterintuitive to explicitly specify the so-called default governor value (i.e., empty defaults to ondemand), but doing so did the trick under xen for my revision G AMD processor.

I tried that...I having the conclusion that perhaps it's the sata_nv and the AHCI drivers provided in CentOS/RHEL 5, 5.1 that they're not well compiled or something because I did install using RHEL 4. that's kinda odd to me...

Re: [CentOS] last resort before hard reboot
On Monday, April 21, 2008 at 6:32 PM, Joshua Frankamp wrote: Is there a resource for CentOS for things to do before a hard reboot? My situation is apparently an out of memory condition where I am seeing fatal 'oops' output all over the place, Ctrl-Alt-F3 (for example) new console login attempts will accept credentials and then never get to a login prompt. Remoting in is just as useless. I cannot therefore use any of the standard restart commands, since I cannot enter commands. By default in CentOs (and on my machine) Alt- SysRq is disabled. Do I have any other options before hard resetting the box? Thanks, - Joshua A quick press of the on/off switch initiates an orderly shutdown on most modern systems. Probably more reliable, from a console (logged in or not), the universal window$ repair procedure ([Alt][Ctrl][Del]) initiates an orderly reboot (init 6). If it appears to be ineffective, it can be repeated multiple times to trigger the reboot. Again, the result is the same you would expect from typing init 6. Given what you have described, you may need to wait a while for either approach to be effective. Steve ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
