Hello I have at this time a w3are 7006-2 controller in my server Dual Xenon 2.8Ghz . But now i will change it to a 9500S-4LP SATA Raid Controller. I have seen in lsmod that the 7000 driver is loaded. scsi_mod 115112 3 [sg 3w-xxxx sd_mod] My question Is it possible to running this card with centos 3.3? I have seen this at 3ware http://www.3ware.com/KB/article.aspx?id=12706 But there is only for 32 b...

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'm guessing 4x PCI Express...

Hi, I used xen-3.0.2-2 (2.6.16) before and the performance of my 3ware 9550SXU-4LP wasn''t too bad, but now with 3.0.3.0 (2.6.16.29) throughput decreased by about 10MB/sec in write performance. sync; ./bonnie++ -n 0 -r 512 -s 20480 -f -b -d /mnt/blabla -u someuser now (2.6.16.29): Version 1.03 ------Sequential Output------ --Sequential Input- --Random-...

...Thanks to the informative message Byron, I realize the deficiencies of doing RAID 1 this way, especially now that the builtin is out of date with Kernel used by Centos. I have 4 ATA drives that were configured in two pairs. I assume that I need a 3Wave controller that has 4 ports like the 7506-4LP...correct? Do I need to install any software during the installation of Centos?

Hello list, I see through the archives that some people here use 3ware RAID controllers with Centos. I have picked up two 9500S-4LP controllers for future servers. I was hoping that if some people could please share their 3ware monitoring scripts with the rest of the group. What I am really hoping to do is have some setup where a cron job runs scripts to test each of the drives connected to the controller to make sure they are...

...erably faster in some scenarios than Opteron machines while not beeing more expensive, I would like to hear some real-world experiences from people who have installed CentOS 4.3 or 4.4 on such a setup. Specifically: CPU: 2x Intel Xeon 5100 2GHz Board: Intel S5000 chipset RAID5: 3ware 9550SXU-4LP I have some experience with the 3ware Adapter (new kernel module needed on install) but now nothing about compatibility, extra drivers or other problems related to the relatively new Xeon/S5000 platform and CentOS 4.3/RHEL 4.3. Thanks for any feedback. -- Bye, Marc Saric

...ld really push you towards a 3Ware Escalade 8006-2 or 8506-4. When cost is supreme, then just a Escalade 7006-2 or 8006-2 with (2) [P]ATA or [S]ATA drives is what you want. It only adds ~$125 to system cost. When you want to minimize cost, but also minimize troubles, I recommend an Escalade 8506-4LP with an EN-8721A02 (Beige) or EN-8721B02 (Black) 5.25" x 3U (3xHH) internal enclosure. SATA was explicitly designed for hot-swap with fixed, SCA-like, staggered, fixed-position connectors with _no_ extra interconnect (i.e., like SCA SCSI drives, SATA drives _should_ connect _directly_ to the b...

...I'm planning a server migration and being able to mount xfs file systems with the live cd would be a cruical feature. So before I download and try ... can anyone tell me whether the xfs is included in the 5.2 live cd? Later on I'm planning to install a new system with xen, 3ware 9550SX-4LP and xfs. The xen domains are of course located on xfs partitions. Do these features come with the standard dvd or do I have to build a custom kernel for that? Under centos-4.5 I chose xfs for performance reasons. With 5.2, is it still the fs of choice when it comes to performance or do you have...

Alle, We have recently had one of our office servers go south. The hardware was an Intel SDS2 motherboard (EATX), Dual Intel PIII 1.4GHz FC-PGA2-L2 512KB, 3GB (6x512MB) 168 pin DIMM, SDRAM 133MHz/PC-133-ECC with 1x3Ware 7006-2 and 2x3Ware 7506-4LP RAID controllers. The OS was RHEL3. Apparently, according to the beep codes, there has been an FRB failure. I've migrated most of the services (mail,web,proxy,samba,mysql,mailman,home directories) to an interim box running CentOS 5.2. At a minimum, I need to replace the motherboard and CPU...

My setup is as follows: Motherboard: Tyan S2895 CPU: Two Opteron 275s Memory: 4 GB Disk: Three 250 GB SATA drives attached to a 3Ware 9500S-4LP RAID card Video: Nvidia GeForce 7800 The only hardware that I have added to the motherboard is the 3Ware card and the Nvidia card. The disks are configured as a RAID 5 array, and the machine boots from this array. I installed CentOS 4.2 x86 on this system without any problems during the installati...

Hi all, after an uprade to new kernel 2.4.21-15.0.4.EL on my server appears a lot of these messages: EXT3-fs error (device sd(8,17)): ext3_free_blocks: bit already cleared for block 19268224 EXT3-fs error (device sd(8,17)): ext3_free_blocks: bit already cleared for block 19268225 EXT3-fs error (device sd(8,17)): ext3_free_blocks: bit already cleared for block 19268226 I try to rebuild array but

Hi, I've got a 3ware 9550SX-4LP on a dual xeon 3.6GHz machine (no HVM possible). 4 SATA-HDs in RAID 5 installed. xen 3.0.3 with centos-4.4 as xen0. centos-4.4 is also installed on the numerous xenUs. The xenUs are installed in LVs which are formatted as xfs. Now I'd like to move over to centos 5.0 This is what I thought to...

Could anyone either recommend a website or howto on optimizing Linux to run asterisk. Such examples of what I mean are.. Renice of asterisk pid's Forcing irq smp_affinity (For interupt hogging T1 cards) .. That kind of stuff, I looked on the wiki and nothing directly mentions server optimization. Or, is this something that *should* be totally irrelevent when dealing with Asterisk. P.S. I

Hello all, I've installed samba on pretty basic install on centos 4.4. I'm running a P4 2.8Ghz, 1G Ram, Raid 5 SATA-2 disks running on both a 3ware and Highpoint Rocket raid (this is going to get swapped out for a 3ware card soon). When users copy files from a mac os x client I'm seeing the cpu load avg (in top) get up to 7. These copies included 150+Gigs of lots of smaller

There have been several threads about SATA in the past weeks and the problems with it. I'm still not clear, though, if SATA in general is a problem or just specific functionality or hardware. Do I understand correctly that "mainboard built-in" SATA RAID is a nono on CentOS? That I would need a third-party RAID card for this? What about SATA non-RAID or SATA2? Is SATA supposed to
