Hi! I have problems to boot with memdisk and pxe the hard drive tests from seagate, hitachi, western digital... does has someone done it and can sym me how? (maxtor works perfectly) ByE

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 All. Yesterday I was installing Centos 5.5 to my web server, and it looks like the main hard drive has gone AWOL. Fedora 12 put the file system into r/o mode. The drive is an Hitachi, still under warranty. There are bad sectors on it, and running the Hitachi DFT tool confirms this. Also I cannot repair the bad sectors. Would this be caused by a faulty I/O chip, or is it safe to say

I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

I''m building another 24-bay rackmount storage server, and I''m considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM drive in both SAS and SATA configurations; the SAS model offers

FYI, Seagate has announced a new enterprise SSD. The specs appear to be competitive: + 2.5" form factor + 5 year warranty + power loss protection + 0.44% annual failure rate (AFR) (2M hours MTBF, IMHO too low :-) + UER 1e-16 (new), 1e-15 (5 years) + 30,000/25,000 4 KB read IOPS (peak/aligned zero offset) + 30,000/10,500 4 KB write IOPS (peak/aligned zero offset)

Hi guys, I don't mean to incite debate or something, just want to share experience and a little curiosity. Back long time ago, we have an old file MS W2K (NTFS) server where due no admin was available to manage it, the server would get power off when the office closed, and auto power on again in the morning. That thing happened for years and it was fine ^^ Recently, I setup a Centos 5.5 file

Happy Friday, List! I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck? Also, if

Hi, Does anyone have experiences about ARC-1883I SAS controller with CentOS7? I am planning to have RAID1 setup and I am wondering if I should use the controller's RAID functionality which has 2GB cache or should I go with JBOD + Linux software RAID? The disks I am going to use are 6TB Seagate Enterprise ST6000NM0034 7200rpm SAS/12Gbit 128 MB If hardware RAID is preferred, the

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would

Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue.

Has anyone worked with either the Hitachi or Seagate Compact flash drives in an IDE to CF interface and set the up with EXT3 formatted partitions for use with LVM? I ASSuME that LVM is not for FAT32 formatted drives.

At my physics lab we have 30 servers with 1TB disk packs. I am in need of monitoring for disk failures. I have been reading about SMART and it seems it can help. However, I am not sure what to look for if a drive is about to fail. Any thoughts about this? Is anyone using this method to predetermine disk failures? TIA

Hi, I am looking into purchasing a new server. This server will be mission-critical. I have read and somewhat understood the theories behind RAIDs 0, 1, 5, 10 & JBOD. However, I would like to get some feedback from those who have experience in implementing and recovering from a HDD failure using RAID. Hardware specs include:- Dual Xeon 3.2 GHz 2 GB RAM I would like to implement

I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one

My setup: A SuperMicro 24-drive chassis with Intel dual-processor motherboard, three LSI SAS3081E controllers, and 24 SATA 2TB hard drives, divided into three pools with each pool a single eight-disk RAID-Z2. (Boot is an SSD connected to motherboard SATA.) This morning I got a cheerful email from my monitoring script: "Zchecker has discovered a problem on bigdawg." The full output is
