[CentOS-virt] CentOS on a stick
Hi, I'm looking into setting up a redundant firewall and I'm wondering how feasible it is to use an USB stick as the only storage device in these systems (i.e. no HDs). The logs will go to a remote logging server but I'm wondering what else needs to be changed to make something like this possible. The idea is to have both systems running independent of each other with the iptables rules being manually kept in sync and conntrackd syncing the connection tracking data. Has anyone experience with this and how would one go about creating such a USB drive? So far I've only used USB for installation but not as an actual root fs itself.

Re: [CentOS] CentOS on the HP MicroServer
-Original Message- From: Timothy Murphy Sent: 03/07/2011 10:52 To: centos@centos.org Subject: [CentOS] CentOS on the HP MicroServer I'm been running two HP MicroServers as home-servers under CentOS-5.6 for 2 months, and have been very happy with their performance. I'm wondering if there are many other MicroServer/CentOS users around? I'm running C 5 x86_64 (currently 5.5) on mine. Given it the full 8GB of ECC RAM. I've put the drive it came with (the 160GB) into the optical drive bay, so it now shows as hdb. I've got 4 x 1.5TB in the main slots, showing as sda-sdd. They are hot swap under C 5, with the kernel happily doing whatever it does when a drive is plugged/unplugged. I've got them as a 3 disk ZFS RAID-Z array, with the fourth as a spare, under zfs-fuse. The write perf isn't great, but most access is over Samba and my wireless / distinctly under par gigabit network, so it serves me well. And we love snapshots and all those other lovely ZFS features, so that outweighs anything else. Also running Squeezebox server and an old version of VMware Server, with a couple of VMs (not under ZFS - that would be too slow). Looking forward to C 6! Glad to hear that SL 6 works OK.

Re: [CentOS] HP Smart Array B110i SATA RAID Controller Driver
From: Kaushal Shriyan kaushalshri...@gmail.com Thanks for the explanation. Please help me understand why do Hardware Vendors provide onboard storage raid controller chipset on the motherboard (fakeraid if its a software raid.). Is it a marketing term for selling servers. Since it does not add value at all strictly speaking due to the fact that the OS is unable to determine the Logical drives. Awaiting your earnest reply. My earnest reply would be that, like winmodems, winprinters and other hybrids, fakeraid is cheaper to manufacture since part of the device logic is done by the driver (at the expense of the server)... So yes, it would be marketing to say we do RAID, while saving on the manufacturing cost of a real raid controller... But dunno who to blame between the server or the motherboard manufacturers... or both. Another marketing ploy I hated was the old drives claiming a xxGB* capacity (*based on a 1:2 compression ratio).

What's interesting though is that none of the distros I've previewed on this laptop have had any trouble with the LAN chipset in that it is able to connect to the network. It's mostly just the WLAN mini-card. Given the choice I'll take an AMD over and Intel processor any day whether it's a server or a desktop.

[CentOS] how to enable Flow Control on CentOS?
Hi, I have an interesting situation with one of our switches. It's a D-Link DGS-3100, 24 port 10/100/1000 Layer 2 Managed switch with some CentOS servers connected to it. On many of the servers I need to disable Flow Control on the switch's ports otherwise the CentOS server's doesn't connect to the switch. i.e. the Switch indicates that the LAN cable is unplugged and CentOS can simply not connect to any host on the LAN. As soon as I disable Flow Control, CentOS breaks. Does anyone know why this would happen, or how / if I can enable Flow Control in CentOS as well? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you looked at the power supply Ljubomir previously linked to in the thread (not the PowerStream unit, but the picoPSU one), you'd see that that particular DC input power supply is built on the ATX connector itself and has no separate mechanical case. And gets 160W output power; which is excellent, for an 'on-connector' power supply. The whole supply is not much larger than the ATX connector itself; seriously, go look at this little gem. At that point you could put a 12V power supply and a sealed lead-acid battery inside the PC case where the PSU normally goes. you'd just have to make sure you add a schottky diode in series, since this picoPSU requires regulated 12VDC input and has overvoltage protection set around 13.0 to 13.5 volts (lead acid float voltage 13.8 typical). A 13.5 volt dry cell string and a 13.5 volt regulated power supply with a pair of 1.5V drop power diodes preventing the dry cells from charging would also work, and that sort of arrangement would indeed be a 'torch' battery (common usage here is 'flashlight' rather than 'torch') and that would fit the needs of the OP. The PowerStream unit can work with unregulated 9-18 volts input, and would be more suited to raw battery input. Again, a diode isolator (similar to an automotive accessory battery isolator diode set) would be required if non-rechargeable batteries were to be used as the backup. Speaking of, I actually have some old Mirapoint rackmounts, running CentOS of course, that have built-in UPS's and redundant PSU's; haven't been able to figure out whose UPS so that I could use them with apcupsd. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Obviously, don't put something in the repo you're not comfortable shipping; the .nosrc.rpm technique, with a documented build setup, to let people roll their own is fine, and has been used before for 'redistribution-restricted' code (like Sun/Oracle Java).

The image in my mind of clamping a hyperbaric chamber over a whole company gave me the laugh of the day, thanks so much for the Freudian slip on 'pressurise'. perhaps thats common usage in your location; in mine we'd say 'pressure' or 'leverage' but reserve 'pressurize' for things like air compressors and such Shame, as Broadcom adapters seem particularly prevalent on AMD-based laptops. I bought an Intel-based laptop where pretty much everything works with CentOS out of the box :-/ The Apple Airport in an Intel Mac is Broadcom; many Intel Dell's have the option of Broadcom, which is typically less expensive than the 3945 or similar Intel wireless chipset. My Dell Inspiron 640m came with a Broadcom card; my Precision M65 had an Intel 3945 but has a Broadcom now (for other various reasons that are beyond the scope of the CentOS list). The one AMD laptop I had that had PCIe wifi had an Atheros chipset. but YMMV.

Re: [CentOS] HP Smart Array B110i SATA RAID Controller Driver
John Doe wrote: From: Kaushal Shriyan kaushalshri...@gmail.com Thanks for the explanation. Please help me understand why do Hardware Vendors provide onboard storage raid controller chipset on the motherboard (fakeraid if its a software raid.). Is it a marketing term for selling servers. Since it does not add value at all strictly speaking due to the fact that the OS is unable to determine the Logical drives. Awaiting your earnest reply. My earnest reply would be that, like winmodems, winprinters and other hybrids, fakeraid is cheaper to manufacture since part of the device logic is done by the driver (at the expense of the server)... So yes, it would be marketing to say we do RAID, while saving on the manufacturing cost of a real raid controller... But dunno who to blame between the server or the motherboard manufacturers... or both. Another marketing ploy I hated was the old drives claiming a xxGB* capacity (*based on a 1:2 compression ratio). Chipset makers are ones to blame for creating them in the first place, since they incorporated cheap RAID support in (almost) every HDD controller chipset. I guess the first one to do it is one to blame, the rest figured it is easier to implement it then explain it is not a healthy choice for data safe keeping.

If you looked at the power supply Ljubomir previously linked to in the thread (not the PowerStream unit, but the picoPSU one), you'd see that that particular DC input power supply is built on the ATX connector itself and has no separate mechanical case. And gets 160W output power; which is excellent, for an 'on-connector' power supply. The whole supply is not much larger than the ATX connector itself; seriously, go look at this little gem. At that point you could put a 12V power supply and a sealed lead-acid battery inside the PC case where the PSU normally goes. you'd just have to make sure you add a schottky diode in series, since this picoPSU requires regulated 12VDC input and has overvoltage protection set around 13.0 to 13.5 volts (lead acid float voltage 13.8 typical). A 13.5 volt dry cell string and a 13.5 volt regulated power supply with a pair of 1.5V drop power diodes preventing the dry cells from charging would also work, and that sort of arrangement would indeed be a 'torch' battery (common usage here is 'flashlight' rather than 'torch') and that would fit the needs of the OP. The PowerStream unit can work with unregulated 9-18 volts input, and would be more suited to raw battery input. Again, a diode isolator (similar to an automotive accessory battery isolator diode set) would be required if non-rechargeable batteries were to be used as the backup. Speaking of, I actually have some old Mirapoint rackmounts, running CentOS of course, that have built-in UPS's and redundant PSU's; haven't been able to figure out whose UPS so that I could use them with apcupsd. Well, it is not viable to run PC of the batteries (for long), but hooking it up directly to the battery of the UPS (so UPS charges that battery) is what I intend to do (There is nowhere to purchase them in my country yet :-( ).
