Though I'm hijacking your thread and probably crossing some boundaries, however, since LSI is actively trying to enhance their products by testing compatibility with Linux distributions, I find this warranted: Can we look forward to something better than megacli for administering LSI based RAID controllers? I, and many others, have to work with LSI equipment daily and they are cumbersome to manage with the only viable tool, megacli. This tool is a very poorly documented - well let's be honest - undocumented piece of software. Yes, there is MSM (MegaRAID Storage Manager) but that's on the opposite end: it's large, uses java, and can't be run on headless servers. Another main problem with the megacli tool is the erratic way you have to specify command-line arguments and it doesn't always match what's in the help. Plus some examples wouldn't hurt. So, although LSI RAID controllers may be compatible with Linux in the sense that they work, by being able to access the configured RAID arrays, being able to administer them in a better way might make a more convicing argument for compatibility with Linux and eventually make the decision process of choosing LSI products easier.

It basically helps the BIOS to boot from the RAID arrays you create but leaves the actual RAID calculations etc... to the driver. Configure the board in IT mode (Initiator/Target). That will disable the FakeRAID. It's jumper JPA2 just above the SAS ports. Once you've done that, clean the drives (dd if=/dev/zero of=/dev/sd? bs=1M) so no signatures from the FakeRAID BIOS remain. After that install CentOS as you would normally and use software RAID (which is better anyway). By the way, the X7DVL-3 is a pretty old board, you say this is a new server?

Re: [CentOS] What NAS device(s) do you use? And why?
In one instance we need to host virtual machines, so we don't need anything fancy. I'm happy with running iSCSI / NFS and even AOE. Currently we have a few 2U SuperMicro servers with 24bays, running OpenFiler. But, OpenFiler is outdated and limited when it comes to scalability. Ideally, I would like to have a single host type setup, for when we move a client to a larger / new / different array, he still connects to the same host - i.e. for high availability. I'd stay away from AoE for high availability, I've tried it at home but performance can fluctuate and the AoE driver present in CentOS 5 is way too old. I wasn't able to build a HA setup without corrupting data when failover occured. For what I'm using AoE - to boot my mediacenter - exporting a single LVM LV, it works perfectly fine for me. For more serious uses, iSCSI is definitely the way to go. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Is anyone using it in production already, and what are your experiences with it? Haven't switched yet, I have IPv6 at home using sixxs. IMO the slow adoption is caused by the complexity IPv6 brings. They should have just modified IP to use 128 bits addresses and leave the rest as is. For example, what is the use of a link scoped IPv6 address? Why would you want to assign an IP address to yourself that's of no use at all? I can't even figure out what address ranges are reserved for private use, is there even such a concept in IPv6? I know that IPv6 is supposed to allow every address to be publicly route-able but having your computers in private ranges and use NAT has big advantages towards security. And what about this arbitrarily chosen /64 subnet? So we're returning back to classfull routing? A provider won't be able to purchase a subnet greater than /64 from for example RIPE?

[CentOS] Tiny webserver to run as root
Hi all Does anyone have a suggestion for some software, a tiny webserver that is able to run as root and execute CGI scripts? It should be smaller than apache and preferably even smaller than lighttpd. It doesn't need a whole lot of features, it only needs to be able to execute CGI scripts. I have tried a few: nanoweb (which is written in php as well) but has some problems with CGI scripts and when it runs in multi process mode it brings the system load up to exactly 1.00. Nullhttpd, but it's old and unmaintained. Tinyhttpd isn't up for the job as well (kept crashing at times).

My hunch is that something in the upgrade process touched sda1 but not sdb1, and that removing sdb1 from the mirror and reattaching it for resync would be sufficient, however I was looking for comments on this from anyone with experience or opinion on the matter. Googling the issue doesn't seem to turn up any recent related results. Also, could the upgrade have touched the bootblock on sda1 but not sdb1 and thus trigger this problem?

Nothing as cheap as a full dl185 that's for sure unless you count SUNs thor (thumper ng) machines but then you'll have to do the raid part in software somehow. Yeah, but that is as easy as zpool create tank raidz2 dev1 dev2 dev3 dev4 dev5 dev6 etc. zfs create tank/bigdisk It's as simple as that when creating your RAID, true. It's more tricky if you have to boot off it, even more if you have to start replacing disks. I have nothing against software RAID, it works fine for me, but you have to know what you're doing. If you really want to go with a HW controller, try Areca or the high- end 3Ware models. IMHO 3ware has kind of fallen out of grace with me, their latests lines were expensive and overall performance was bad compared to Areca. Maybe that has changed in meanwhile but I'm not buying them anymore. As mentioned in any ZFS document, when you use a HW-raidcontroller, the OS never knows if a drive is broken or showing errors. The HW hides that from the OS. That's basically the whole point of a hardware RAID controller. But it doesn't mean the OS can't analyze the RAID controller's (and disks) status, see next paragraph. You have to have closed-source drivers like the HP utils to tell you that. Not entirely true, the cciss driver is open source and you can use an easy utility like cciss_vol_status to monitor your RAID. Though if you want to manage your RAID array beyond basic checking of status and replacing broken disks, you'll have to use the HP management utilities (you can get them from their website), which are, yes, a bit dire. Such as requiring 32 bit libs in their 64 bit packages, FAIL if you ask me. (Note that you don't have to use HP's driver for cciss for their management utilities to work - they work fine with the drivers that ship with CentOS). In addition, smartmontools is capable of monitoring the individual disks behind a cciss RAID controller. Even more, the failure LEDs on the backplanes work, something I haven't seen possible to use in combination with software RAID. If your data-set will, over the lifespan of that server, never grow beyond the original size of the array, then you can go with a HW- raidcontroller. Otherwise, go ZFS. I see no reason why a growing dataset is an argument against a hardware RAID controller. You can just add disks, create new arrays and use LVM. My few pro's/con's software vs. hardware RAID: Software RAID: + Portable: any controller will work and the management is the same + Can span anything that's a block device + Cheap + In RAID 1 10, the independent parts are readable without the RAID functioning - Failure LED's don't work - Removing a drive can be tricky involving the scsi remove-single-device command. Once this command didn't even work and yanking out the disk without the remove command made the server lock up. - When replacing disks on a bootable set, you have to remember to re-install the bootloader Hardware RAID: + Failure LED's work when used in conjunction with a backplane (might require additional cabling) + Possibility for a battery backed write cache + Just works (at least for HP) +- Somewhat portable if you remain within the same brand. Excellent experience with HP Smart Array controllers in this regard. - Management tools can be a PITA on linux. - Expensive - Some controllers have such a way of storing the data on disk that you can't read them back on a regular controller without additional tools Best regards, Glenn ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

From a closer look at the output, I believe the problem might be in file /usr/lib/jvm-exports/java/jdbc-stdext.jar, which might be JDBC (from where I think java.sql.Wrapper comes) for Java 6. Where do you have this file installed from? Hello [r...@testserver build]# rpm -qf /usr/lib/jvm-exports/java/jdbc-stdext.jar java-1.6.0-openjdk-1.6.0.0-1.2.b09.el5 I wonder why the build procedure is looking at that file... Do you have CLASSPATH exported when you run rpmbuild? If so, try unsetting it before running the command. I did not have the CLASSPATH environment variable set. You may also try to move that file (and maybe the Xerces file) to another directory and then try to build the package again. That jdbc-stdext.jar file gave me a clue, I did a yum remove java-1.6.0-openjdk-1.6.0.0-1.2.b09.el5, and now the package builds. As I'm using the Sun implementation now the openjdk one is obsolete, however, I wonder how Red Hat builds the RPMs. Did they use the Sun JDK as well? I also see you are building the RPM as root, that is not advisable (as a bogus or malicious spec file might damage your system), you should build RPMs as a regular user, if you want more details on how to do that look at this Wiki article: http://wiki.centos.org/HowTos/SetupRpmBuildEnvironment#head-556b8aa080c4fc427757f25b9c229f600827f09d I know, but this is only on a test machine, security is not really a high priority at the moment.

Re: [CentOS] Battery condition tools CentOS/Dell
Kwan Lowe wrote: Hello all: Does anyone know of a tool/project that will allow me to read the battery condition (not the charge status) on a Dell laptop battery? Under XP there is a utility that warns that the battery is still holding a charge but that the battery is degraded and should be replaced. Also, not sure if this is possible, but I would like to control how the laptop charges the battery. I tend to have the laptop plugged in most of the time and this constant charging state is apparently very bad for battery lifetime. So a charge/drain cycle is supposedly better. Thanks, Kwan Li-ion batteries should be charged early and often. Deep discharging will shorten its lifetime as part of their normal usage cycle. I don't see how charging them to 100% is negative for the battery's lifetime as they do not have the memory effect. Li-ion batteries degrade as soon as they are produced, when they are not being used you should charge them to about 60% and store them somewhere cool, dry and without light.

As the Wiki article linked previously mentions, LiION batteries deteriorate over time and with use (as do all batteries). In my experience, a typical laptop battery (treated well) will last 2 years while maintaining the majority of its original capacity. After 5 years, the battery run time is often inadequate to meet the needs of the owner. When purchasing a laptop, I would have the expectation that the battery will need replaced every 2-3 years - if the laptop is used, assume that it needs a new battery. The laptop is about 18 months old, so the battery was nearing its end but I'd hoped for at least another 6 months of useful time (more than 10 minutes). The battery is in worse condition than three identical batteries in the other 3 laptops purchased at the same time. The main difference is that this laptop is plugged in continuously while the others are mobile. That's usually a symptom of an individual cell that has failed. You could open up the batterypack and start replacing the individual cells, but I'd recommend just getting a new battery or even a new laptop...

Does anyone know of a PCI modem that works out of the box with in-tree kernel drivers? Does it *have* to be a PCI (internal) modem? Except for a few *very expensive* ones (3Com/US Robotics *used* to make one I think), they are all 'controllerless' modems (aka 'winmodems'). Controllerless modems are poorly support under Linux, and there is little or no motivation for the kernel developers to bother supporting them. It might actually be easier to get an old ISA modem card (off eBay), except modern computers don't have ISA busses anymore :-). It would actually be cheaper (and far easier) to get an *external* RS232 modem. At worst you'll need a serial port card (Lava's PCI serial port cards are quite well supported). In effect the combination of a Lava PCI serial port card and a RS232 modem would be a PCI modem, although the 'modem' itself would be external. Hi It doesn't need to be a PCI modem, but I would prefer one because everything can be nicely tucked away than and it's less wiring. But if only oldskool external serial modems do the job I'll use that then. Just to confirm, something like this one: http://www.usr-emea.com/products/p-dialup-product.asp?prod=hom-5631aloc=bene will just work out of the box?

I'm also wondering how Red Hat / CentOS will handle such a problem -- or have they already addressed it? Probably shouldn't worry about a possible problem, but I do anyhow. I had the same question in the back of my mind. There are some great evolutions going on right now, but they take a lot of time to mature. I've also been wondering about desktop environments, since fedora 10/11 use KDE 4, which, even 4.2, I find very low in quality compared to 3.5, how will Red Hat provide a decent desktop?

Re: [CentOS] Swap priorities with swapon (Is my swap drive working?)
James Bensley wrote: Hey Listee's I have a CentOS server with 2GB of ram and a swap drive of 4GB; swapon -a shows my swap drive as 4GB with only about 350 bytes in use (which is fine as my server idles with about 350-400MB ram usage so no swap should be in use. However my one and only swap drive had a priority of -1. I had read that the swap drive priority doesn't matter too much because I only have one swap drive so the kernel hasn't got to make a choice but also that after a certain kernel version (which is think was like 1.3.x?) it didn't even use the priority value and my kernel is newer (I have 2.6.18-128.1.6.e15). Basically I have read difference things from difference source on the old interwebwrok and seek clarification. In the confusion I set my swap drive priority from -1 to 1 because I thought that if the drive priority were a negative value it might not actually use the swap drive. Ultimately I can't tell because there currently isn't enough memory usage demand on the server. On a side note: I'm a reformed Windows admin and have seen the light and am moving each server one at a time over to Linux so I am used to poor memory management and needing massive page files. Realistically the swap drive shouldn't been in use but I am just worried then when this server goes live it will hit 2GB of ram usage and the swap won't kick in. Is there anyway I can check? If your system starts to swap, it really needs more memory. Otherwise you're just fine. Swap is only a last resort. Don't worry about it.

This is an extract from /var/log/acpid when the powerbutton responds: [Wed Apr 1 15:36:46 2009] client connected from 2332[0:0] [Wed Apr 1 15:36:46 2009] 1 client rule loaded [Wed Apr 1 15:37:16 2009] received event button/power PWRF 0080 0001 [Wed Apr 1 15:37:16 2009] notifying client 2198[68:68] [Wed Apr 1 15:37:16 2009] notifying client 2332[0:0] [Wed Apr 1 15:37:16 2009] executing action /usr/bin/pm-hibernate [Wed Apr 1 15:37:16 2009] BEGIN HANDLER MESSAGES [Wed Apr 1 18:10:47 2009] END HANDLER MESSAGES [Wed Apr 1 18:10:47 2009] action exited with status 0 [Wed Apr 1 18:10:47 2009] completed event button/power PWRF 0080 0001 After the first resume, nothing like that appears in the logs, like the powerbutton was never pushed. I have acpid version 1.0.4-7.el5 installed, I did not experience this issue on another distro which ships with acpid 1.0.8.

Phil Schaffner wrote: RedShift wrote: Another way to get CentOS on such a configuration would be to do everything manually, thus installing the base system by creating the necessary disk allocations and then rpm -i all the required packages to get it to boot. (I've done this before, it's not a big deal, you just need to follow a certain order - I remember documenting it somewhere but forgot). But since this method is probably not officially documented anywhere or even supported I'll most likely won't get any support if this setup were to fail somehow (like when upgrading between minor versions). I've tried STFW'ing, but searching for centos and partitionable arrays is too ambiguous. I tried googling too, and came up with lots of docs on partitionable arrays, but nothing on installing. Can't say for sure without testing, but I suspect GRUB would choke on this. Would probably still need at least a /boot on a separate partition, or a standard RAID1. GRUB works at least with a RAID 1 setup. (I run it in production on another distro). On a partitionable RAID 1, the data can still be read independently from the disks (that allows GRUB to work). If you have two disks you would install your GRUB MBR twice, once on both disks using the GRUB shell. I haven't tried other RAID forms but I see no reason why the built-in RAID 10 would not work as well.

So instead of having two disks, creating an identical partition table on both and then putting those partitions in RAID 1, you take those two disks and put them in one partitionable RAID 1 array (in mdadm terms, mdp) and create a partition table on the new RAID device. The advantages are quite clear compared to the old non-partitionable arrays. For the uninitiated, would you be kind enough to elaborate the advantages of mdp? I have always created identical partitions on the raw disks first, and the used mdadm on top. I also create my partitions ~200MB smaller than raw disk capacity to ensure minor size differences between disks (eg. 160GB HDD from Seagate is not exactly same size as a 160GB disk from Samsung) will not prevent me from adding them to a raid set. Does mdp handle this scenario? When you run a partitionable array you don't have to care about the partition table on the independent disks. So when a disk fails, you don't have to recreate the exact same partition table, you just swap the device using the mdadm tool. Another advantage is that you don't have to do the disk swap for every partition. For example, in the old scenario, you have two disks (sda and sdb) with 4 partitions on them each. On those 4 partitions you create your RAID arrays, like md0=sda1,sdb1; md1=sda2,sdb2; and so forth. When sda fails, you have to remove the failed disk from all of the 4 RAID arrays and when you've put in the new disk, you have to signal all 4 arrays that the new disk is to be used. Not only do you have to execute 4 times as much commands, reconstruction of the 4 arrays will take place in parallel leading to slow disk access during reconstruction. When reconstructing a partitionable array using whole disks, reconstruction will always be sequential. In the disks not being equal scenario: you can limit the size of the RAID array during creation with the -z parameter (man mdadm, chapter For create, build, or grow:). So instead of limiting the size of the partitions you create, you limit the whole size of the RAID array. So having a smaller replacement disk is no problem as long as it's equal or bigger than the array size you defined during creation.

When I have replaced a disk and added several partitions to an array, the rebuild is done one partition at a time. The /proc/mdstat would say delayed on the partitiones waiting. Mogens I must be mistaken then, it's been a long time since I've used regular md devices.
