I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance... System specs: ----------------- 2 x 2.8GHz Xeons 6GB RAM 1 3ware 9500S-12 2 x 6-drive,

Why can't non-uid 0 users have more than 1024 file descriptors when logging in via ssh? I'm trying to allow a user to have a hard limit of 8192 file descriptors(system defaults to 1024) via the following setting in /etc/security/limits.conf: jdoe hard nofile 8192 But when jdoe logs in via ssh and does 'ulimit -Hn' he gets '1024' as a response. If he tries to

Hi everyone, I'm looking into setting up a SATA hardware raid, probably 5 to use with CentOS 4. I chose hardware raid over software mostly because I like the fact that the raid is transparent to the OS. Does anyone know of any SATA controllers that are well tested for this sort of usage? From what I can tell from googling, this is more or less where RHEL stands: Red Hat Enterprise Linux

Hi Everyone, Has anyone had any experience of using the Promise FastTrak SX4000 or SuperTrak SX6000 IDE RAID Controllers under Centos (if it matters I'm using version 4). I've seen it listed on linuxcompatible.org as working but would prefer to find out any first-hand experince before I buy. I'm looking to build a new mini server based on Mini-ITX and have found a great 1U case

I just built up a server running CentOS 4.3, and trying to boot from a 3Ware 9550SX-16ML, 16 port card. This system has 9x500GB drives, AMD Opteron, Tyan K8SD mobo and 1 GB of ram. I downloaded the latest (9.3.0.4) driver from 3Ware, and after a couple of botched attempts, I got CentOS installed. In my two botched attempts, the problem was X hanging during the formatting of the drives, so I

I've been planning to build a dual Opteron server for awhile. I'd like to get people's suggestions on a suitable motherboard. I've looked at the Tyan K8SE (S2892) and K8SRE (S2891) but would like to find more Linux-specific experiences with these boards. Some features I expect are at least 4 SATA (SATA-300?) ports, serial console support in the BIOS, USB 2.0 and IEEE-1394

My goal is to be able to install to the drive array on the 3Ware controller card. 3Ware does provide a RH WS 3 driver that I've tried to use; however, the RH Enterprise 3 WS driver doesn't work since that kernel is older than the CentOS-3.1 install kernel. I'm trying to create a centOS-3.1 installation driver disk for the 3ware 9500S card; however, I'm not having much luck.

Hi, We are having a problem between Linux 2.6.9-prep #12 SMP Mon Dec 6 12:08:34 CST 2004 x86_64 x86_64 x86_64 GNU/Linux (Samba version 3.0.9-1.fc3) and MAC OS X 10.3.5 Samba version 3.0.0rc2 Basically the issue is that the Mac reports the Linux share as being full, and won't allow files to be copied. We are able to work around it using this method: Create a folder on the Linux

Hi, I'm having lots of difficulties with BCM5719, which is the default network card of HP Proliant DL 360 G8 servers. I can get a few ping replies before I get a couple of these: bge0: watchdog timeout -- resetting bge0: watchdog timeout -- resetting Then everything hangs. Can not log in using ssh.

From a buddy of mine that has spent a little time with the new cards. This was in response to my email asking about his impressions of them: It just came out in mid-September. There are a couple reasons I'm not thrilled with it: 1) no 8-port multilane version (only 12) 2) the 8-port non-multilane version is a kludge, connector-wise (a row of 3 double-stacked connectors along the

Hi, this server, a Dell R720 has 4 bge on board, Broadcom NetXtreme Gigabit Ethernet, ASIC rev. 0x5720000 bge0: APE FW version: NCSI v1.1.7.0 bge0: CHIP ID 0x05720000; ASIC REV 0x5720; CHIP REV 0x57200; PCI-E miibus0: <MII bus> on bge0 ...

I'm experiencing similar problems with a 3C996-T under 4.8-REL. In particular, connecting a 4.8-REL machine to a 5.1-REL machine leads to some interesting situations: I can do simple pings across the link, but ssh fails, and heavy pings crash the 4.8 machine. Similarly changing the interface configuration with ifconfig tends to crash the 4.8 machine (mtu, link0, up/down, etc). The

Hi I am trying to find a good PCI 64 SSI 320 raid controller to use with Centos & 4 10k drives as raid 1 & 0 to get the best I/O speed, any clues as to what people have found to be the best. Thanks Denis

How slow and how reliable is software raid 6 on CentOS 5. The system I'm going to use is A socket 939 dual core Athlon, 4 gigs of ram and a 3ware 7506-8 controller. Its mostly going to be used for storage (Movies, MP3s etc.). Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I really hope someone has a clue on this one.... :) I've got a 2.2TB array mounted on a 3ware 9500 controller. I installed it last week ensuring that LBA was enabled and using gpt with parted to get the full size available on one array. I also think I chose reiserfs for the array. We then moved ALOT of data to the array. Problem now is that after a reboot LBA doesn't seem to be in

Hello everyone -- I am stumped on this issue, mostly because I'm not quite sure if it's behaving correctly or not. I believe this used to work and right now I'm not quite sure why it's no longer doing so and how to fix it (if possible). I suspect it is because of my recent update of the OS and Samba version. When users are trying to follow a symlink that goes to a different

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I installed centos4 on a raid system with 7 400GB Hitachi SATA disks in RAID 5 on the 3Ware card. I set up a 2.2TB EXT3 Partition /opt.

However a reboot dropped

Hi list, I need to process a Rnw file and and a csv file (both are encoded in UTF-8) under Windows XP (R Version 2.11.0, i386, mingw32).
