I have 12 750GB drive appliance from HP. I was wondering what is the best disk configuration? I suppose a large RAID5 would be bad since rebuilding would take too long. What do you recommend?

I have a 750Gb 3-member software raid1 where 2 partitions are always present and the third is regularly rotated and re-synced (SATA disks in hot-swap bays). The timing of the resync seems to be extremely variable recently, taking anywhere from 3 to 10 hours even if the partition is unmounted and the drives a...

Hi all, Can anyone please tell me, from experience, if it's possible to upgrade the hard drives in a RAID 10 system from 250GB HDD's to 500GB / 750GB HDD's, while the server is running? The server runs CentOS 5.5 x64. Our hardware vendors simply always say no, so we never actually tried doing this, and when a client needed an upgrade like this we had to build a new server with the same spec and larger hard drives and then migrate the data a...

I have CentOS 6.x installed on a "HP ProLiant DL380 G5" server. It has eight 750GB drives in a hardware RAID6 array. Its acting as a host for a number of OpenVZ containers. Seems like every time I reboot this server which is not very often it sits for hours running a disk check or something on boot. The server is located 200+ miles away so its not very convenient to look at....

Hello all, This is the laptop I own: HP Pavilion dv6t Quad Edition Spec: Intel Core i7-2630QM 2.0GHz, 6GB RAM, 750GB HDD, VGA ATI Radeon HD 6490M You can also check the spec here: http://www.amazon.com/HP-Pavilion-dv6t-dv6tqe-Laptop/dp/B00506B7DS/ref=sr_1_3?s=electronics&ie=UTF8&qid=1312164145&sr=1-3 I am going to install CentOS 6 to it but I want to make sure that which drivers will CentOS 6 sup...

Hi all I want to look at setting up a simple / cheap SAN / NAS server using normal PIV motherboard, 2GB (or even more) RAM, Core 2 Duo CPU (probably a Intel 6700 / 6750 / 6800) & some SATA HDD's (4 or 6x 320GB - 750GB). My budget is limited, so I can't afford a pre-built NAS device. Can this be done with CentOS? I've been looking FreeNAS (which is built on FreeBSD), and it look like a great project, but since the hardware support in FreeBSD is limit, I'd rather use Linux for it. Has anyone done...

...get by the boot process, and discovered my sata controller could not handle the newer SATAII disk.. No boot was possible. I finally got the sata contoller in shape to work by flashing the 2 part BIOS with latest bios for that card. (Sil 3112a chip). Restarted with 1 original 200gb disk and 1 new 750gb disk. It booted and I was abble to attach the new larger drive and begin the resilvering process. I went on to other things, but when I checked back I found the error report cited above. I stared looking through the data but didn''t really see much wrong. I check the byte size with `du...

I have two openvz servers running Centos 6.x both with 32GB of RAM. One is an Intel Xeon E3-1230 quad core with two 4TB 7200 SATA drives in software RAID1. The other is an old HP DL380 dual quad core with 8 750GB 2.5" SATA drives in hardware RAID6. I want to figure out which one has better random I/O performance to host a busy container. The DL380 currently has one failed drive in the RAID6 array until I get down to replace it, will that degrade performance? Is there an easy way to test disk I/O? O...

Hello, I have a Promise EX 12-port RAID controller in my box, connected to 8 750GB disks. I have set up 2 RAID-5 devices and joined these using LVM. This is working fine. However, there is something that seems wrong.. (4-1) * 750 = 2250, but df reports the LVM volume as a mere 4.0T; /dev/mapper/storage_volume-stor 4.0T 3.6T 507G 88% /storage Shouldn't this be 4.5TB?...

Hey folks, So what's the word on AHCI and bios drive geometry? I'm having a real pain of a time trying to get some 750gb sata drives running on my FreeBSD7 box in AHCI mode. It doesn't seem to matter what disk geometry I suggest to sysinstall, something complains of an invalid disk upon booting it. Actually, in AHCI mode the bios screen doesn't report any information on drive geometry, so all bets appear...

Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*. I am trying to configure 2 identical servers, both are Dell Poweredge 2970 machines with 6 disks in them

hail, I have an old AthlonXP 1700+ running 7-STABLE: FreeBSD xxx 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #1: Thu Nov 13 23:54:59 BRT 2008 root@xxx:/usr/obj/usr/src/sys/xxx i386 where I have two 750GB Seagate SATA Disks. They are divided as two slices, around the first 120GB are gathered in gmirror, and what left is in gstripe. so that's whats going on. if the machine locks, and fsck comes to make its job, the box just gets slower and slower till I have to reset it the hard way. to make it n...

Hi everyone. This isn't specifically a CentOS question, since it could apply for any distro but I hope someone can answer it anyway. I took the following steps but was puzzled by the outcome of the test at the end: 1. Create a RAID1 array called md3 with two 750GB drives 2. Create a RAID1 array called md9 with two 500GB drives 3. Initialise md3 then md9 as physical volumes (pvcreate) 4. Create a new volume group called "3ware" with md3 (helps me remember what controller the disks are on) 5. Use vgextend and add md9 to the 3ware volume group. 6. A...

I am running rsync in cygwin on windows. I am attempting to backup a somewhat large data store (750GB) to a remote site. As its windows and preserving permissions exactly is important, I have an iSCSI drive mounted on the local system across a somewhat slow WAN link (IE, it would take about 3 months to copy the datastore over it). Unfortunately, since this appears as a "local" copy to r...

Hi, Segate has released the ST3750640AS 750 GB sata drive. I would like to take two of these and plug in to a the Nvidia Nforce 4 Sata I/F an run Zfs on . ( I have installed SXCR build 40 on a shuttle SNP25 PC last weekend with some install problems I reported in the install-discussionlist ) I there any limitations anywhere in the path to the drive that would

...s=104 kernel: ATA regs: error 10, sector count 20, LBA low ff, LBA mid ff, LBA high ff, device 4f, status 51 which results in the disk being dropped from the array. A sharp eyed engineer at Highpoint has just spotted the fact that the read error reported later is well beyond the end of the array ( 750Gb ): kernel: g_vfs_done():da0s1h[READ(offset=535260184576,length=131072)]error = 5 As such is it possible there is a problem in the FS that fsck is not detecting which could be causing this behaviour when an rsync ( read only ) is performed against it? If there is indeed a vfs error which fsck is n...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I''ve been unable to find anything definitive about what happens if I use RAID0 to join an SSD and HDD together with respect to performance (latency, throughput). The future is obvious (hot data tracking, using most appropriate device for the data, data migration). In my specific case I have a 250GB SSD and a 500GB HDD, and about 250GB of

...d the possible suggestions that may arise from admitting it, that the array also supports FireWire and SATA connections. (we are STRONGLY inclined to wanting to use the array as USB, as our primary concern is easy portability and not speed) the RAID array is the DatOptic eRAID, with 5 750GB disks in a RAID-5 array. the array itself seemed to have no problem creating the ~3TB volume, but it does not detect as that size when i hook it up. here are the relevant kernel logs: SCSI subsystem initialized Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB...

Is there a way to update a CentOS 5.4 server to 5.6 (but not 5.7)? "yum update" takes me all the way up to 5.7. Best, -at

Does anyone know if 4k sectors will be handled better by the kernel in Centos6? I'd like to copy backups to a 750Gb laptop type drive for offsite storage but the best write speed I can get is about 8MB/sec even with dd to the raw disk which shouldn't have an issue with partition alignment. -- Les Mikesell lesmikesell at gmail.com
