I'm running a server with Centos 3 that I have set up a smbfs share to a Buffalo LinkStation. The LS has 4 drives configured with RAID 5. Each disk has 1 TB capacity, so the resulting drive is approximately 2.7 TB. When doing a df, the result shows 2 TB, and no used blocks. Is there some setting I can change so that Centos sees and uses all 2.7 TB or does Centos 3 not support this? Steve

We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg

Two problems I hope to solve: 1. The switch being used has autoneg off and has port set to 100 full duplex. 2. Many times NIC fails to come up properly during PXE boot: r8169: eth0: link down ADDRCONF(NETDEV_UP): eth0: link is not ready I can't use ethtool to disable autoneg because the nic driver is built into a bzImage. The root fs is currently being mounted via nfs during pxeboot at

Greetings. I am planning on getting my RHCE in the near future. I thinking I should wait until 6 comes out before proceeding. That being said, I don't want to wait past the end of this year. That being said, do you all have any information about how long it takes for their training platform to catch up to their release? Which is to say, if RHES 6 is released on day 1, at what point

Greetings, I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box.

Greetings. Sorry for the OT, but I'm looking for some advice regarding archiving. I've always been a tape archive believer, but with SATA drives becoming more reliable and much larger, I'm wondering if it is time to change my opinion. What are the benefits/pitfalls to begin archiving to "enterprise" level SATA drives? Is it possible to use Amanda or Bacula to archive

I am having an extremely strange issue with a BL460c1 (G1) blade on a c7000 enclosure. I could not for the life of me get the machine to ping the gateway or any other blade on the same enclosure (yes, the subnet mask was correct & quadruple-checked); although pinging to the local IP works. I was almost convinced that it was a network or hardware issue; until I asked someone to try

I come across some problem when using xen-4.1.1-rc1-pre from xen-4.1-testing tree and 2.6.32.36xen linux kernel from git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git. when I use ''xend restart'' , it hangs when kernel dmesg printing ''Bridge firewalling registered'' and the console show below messages: localhost# xend restart Nothing to flush.

I know there are a few 3Ware fans here and I was hoping to find some help. I just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5. The array is fully initialized but I'm not getting the write performance I was hoping for -- only 40 to 45MB/Sec. 3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express version of this card (the 9580 I think.)

I have no output in the logs, but /etc/init.d/network restart fixes the issue. I am rsync/scp (10GB) data from one 100MB Full duplex host to an ASUS M3A78-EM (RTL8111B/C). It locks up around the 1.5GB Tx mark. If I ethtool -s eth0 autoneg off speed 100 duplex full it does not happen again. Ideas? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -

Greetings. I am in the process of installing 5.1 64 bit on a server. The server has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA. I want the 8006 board to be /dev/sda, and the 9550 to be /dev/sdb. My plan is to install the os on /dev/sda (8006), and data on /dev/sdb (9550). Unfortunately, the 9550 comes up as /dev/sda. The 8006 is installed in slot 3, which is a 100Mhz

Since good server designs have come up in the past, I wanted to point out a "low-cost" server option that has good I/O, and the vendor offers _your_choice_ of not only Fedora Core or Red Hat Enterprise Linux, but _also_ CentOS _shipped_ with it! IN-A-NUTSHELL ... Starting at just over $750, you can get a single Socket-939 Opteron 1xx (dual-core is an option) system with up to 4GiB of

Dear list, I thought I'd just share my experiences with this 3Ware card, and see if anyone might have any suggestions. System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID 1 plus 2 hot spare config. The array is properly initialized, write cache is on, as is queueing (and supported by the drives). StoreSave

Hi I installed xen by following this link: http://www.howtoforge.com/virtualization-with-xen-on-debian-lenny-amd64 Dom0(debian) has two IP :174.x.x.79 , 67.x.x.32 gateway is 174.x.x.65 DomU(win2003) IP is :67.x.x.38 The problem is : 1.weird network issue in win2003(can not access the internet in win2003): A:weird ping time for 127.0.0.1 B:weird ping time for its own ip 67.x.x.38 C:timeout

I can't explain why 700 msecs aren't enough to avoid timeouts in 100 Mbps networks, but my tests verify it, so I'm writing to the list to request that you increase the default timeo to at least 30, or to 600 which is the default for `mount -t nfs`. How to reproduce: 1) Cabling: server <=> 100 Mbps switch <=> client Alternatively, one can use a 1000 Mbps switch and

Hi, At first glance, this appears to be a fairly simple routing issue, but I''ve checked the configuration and am a bit mystified. I am using Xen 3.0.2 here in bridged networking mode. Firstly - four servers. Dom0 - 75.126.2.202 (RHEL4) domU (CentOS) - 75.126.3.248 -> 75.126.3.251 Dom0, .248, & .249 can all talk to each other okay (& the outside world) However, for some

based on what your saying.. im not thinking this is samba related. I guess check your switches and find the "fault" autosense for your nics.. You can use thisone to disable autosence ethtool -s ethX autoneg off en set correct nic speed. ethtool -s ethX speed XXXX BUT ! check your switches first. greetz, Louis >-----Oorspronkelijk bericht----- >Van: sambait3 at

I think I got it. Both nfsmount and `mount -t nfs` now default to rsize/wsize = 1 MB. By lowering this to 32K, all issues are gone, even with the default timeo=7. And nfsroot=xxx client responsiveness is a whole lot better. I think when nfsmount was initially written, the default rsize/wsize were much lower, which matched the timeo=7. Now they cause the lags/timeouts that I reported. So

Win2K box and the file server are on the same switch. They are both configured as 100FD, AutoNeg=Off. I have not met anyone so far with that much performance difference, though some reported 1:2 speed ratio. Attached is our config file for your information. I've searched through this mail lists' archives. I couldn't find a solution, though I've seen people reporting similar

I have the latest kernel with the drivers for my 3ware 9550SX built in. Where can I find the tools and monitoring apps for this card? Are there rpms hiding somewhere, or do I need to build it from source? -- Bowie
