I've got an i386 server running centos 4.2 with 3 3ware controllers in it -- an 8006-2 for the system disks and 2 7500-8s. On the 7500s, I'm running an all software RAID50. This morning I came in to find the system hung. Turns out a disk went overnight on one of the 7500s, and rather than a graceful failover I got this: Jan 6 01:03:58 $SERVER kernel: 3w-xxxx: scsi2: Command

Hello, Queries: 1 - what is the best RAID (0,1,5,10,50) for server running very, very VM instances ??? 2 - and config of stripes/element sizes (32, 64, 128, 256, etc, KB) ?? 3 - in the configuration of VM, exit one difference in performance between image file (disk:/) or LVM partition (phy:/) ??? any URL or docs for read about this theme ? mmm.. it is all for moment. thanks -- -- Victor

I have 8 WD SATA HDD with raid ready (3mbps) hard disks on a 8 port 3ware controller.(on raid 5.) Does anyone have a comparison on SATA raid and SAS raid disk. As you know SAS disk are very expensive and I would like to know from experts in the list who could suggest which of the following would be the best. Option 1) 2 servers each having 2.0TB raid disk with SAS drives, 2GB ram and standard

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?

Hi All, I''ve just built an 8 disk zfs storage box, and I''m in the testing phase before I put it into production. I''ve run into some unusual results, and I was hoping the community could offer some suggestions. I''ve bascially made the switch to Solaris on the promises of ZFS alone (yes I''m that excited about it!), so naturally I''m looking

Hi people... Here we use Xen 4 with Debian Lenny... We''re using kernel 2.6.31.13 pvops... As a storage system, we use AoE devices... So, we installed VM''s on AoE partition... The "NAS" server is a Intel based baremetal with SATA hard disc... However, sometime I feeling that VM''s is so slow... Also, all VM has GPLPV drivers installed... So, I am thing about

If we''ve abandoned the idea of putting the number of redundant blocks into the top bits of the type bitmask (and I hope we have), then we''re fairly much there.

I've got a new PE2950 rack system with PERC controller and 6 drives set up contiguously as one RAID5 volume on the PERC controller. Using 64-bit CentOS 4.4, I partitioned for /boot having 100 Meg, swap having 2 gig, and / with the rest (removed LVM). After the install was complete, the system rebooted and just gave me a broken grub prompt (not the graphical Grub boot selector, but

Hi there, Sorry for the dup, here are more informations. I'll soon run RedHat4 U4 ES with multiple 4TB partitions made of a 7-disks RAID5 array. Almost all files on these partitions will have a fixed size of 32MB. Should I leave the default raid chunk size to 64k with ext3's 4k blocks ? What are the best tweaks around to optimize overall performance ? Thanks, Ionel -- Ionel GARDAIS

Hi, I sent a message to linux-kernel that describes exactly what I did to thourally fsck up my ext3, but now I'm trying to see if I can recover more than the ext3 kernel driver will let me get to... http://marc.theaimsgroup.com/?l=linux-kernel&m=106745677408810&w=2 Now that you've read that, and you haven't given up hope (stubbornly like me), then I'd like to know what I

Hi, originally I posted this to linux-raid@vger.kernel.org, but I guess there are chances that someone in here might comment on it as well.

Further to my posts a few days (weeks?) ago, here''s an update on the situation. After the the Raid array finally rebuild, CentOS4 installed and now runs without a problem. The card is an adaptec 2410SA SATA raid card. Michael Weisman The Ad Doctors mike@theaddoctors.com

Hello, ?s there anyway to create raid6 or raid5 level glusterfs installation ? >From docs I undetstood that I can do raid1 base glusterfs installation or radi0 (strapting data too all servers ) and raid10 based solution but raid10 based solution is not cost effective because need too much server. Do you have a plan for keep one or two server as a parity for whole glusterfs system

I just noticed something very strange on one of our Dell PE1750 servers. It is running FreeBSD 4-STABLE on dual CPU's with the embedded Dell Raid controller (amr driver). Attached are 3 disks of 145GB. On a RAID5 logical drive this gives me ~280GB storage. Up until the last reboot (35 days ago) the 'amrcontrol' status utility gave me: Logical drive 0 Stipes blah Size blah
