Has anyone experienced a significant degradation in ext3 performance when using it on a Multi-TeraByte RAID? As part of an experimental setup, I hooked up three 300GB drives and made an EXT3 RAID5 out of them, using the entire space one each drive, and started throwing a large number of files in the size-range 3KB to 50 KB. Then, I deleted the raid, and created a new one, but this time, I used

hi. i'm hitting a wall each time i try to format a 3 terabyte partition. i'm able to create the partition using parted but whenever i try to create a 3 terabyte xfs or jfs or ext3 filesystem, the mounted filesystem created is only 1 terabyte. i tried centos x86 and x86_64 4.0 but i always hit a 1 terabyte limit. please help.

I'm looking to add a sata raid controller to my server, give it a terabyte of HDs and make a myth backend. I'm having trouble determining if this raid block is compatible with linux. Does anyone have any experience with this item? http://www.plinkusa.net/webBP-SATA3141B.htm

I'm curious to what people are using for backing up their samba servers. Here's are some specs to consider: - 1TB (yes, that's terabyte) of data - multiple servers backup to one tape drive connected to a server (preferably a linux system) - using an autoloader (in this case, an HP 1/9 LTO system) - need to be able to backup daily changes and/or changes since last full backup

Hello, I have an Lacie NAS disk attached to an Gigabit network. Since it only exports samba I mounted on one of my gigabit Linux boxes with smbmount //lacie/terabyte /TERABYTE -o defaults,username=genuser,password=genuser Now I need to export that to all my linux boxes not on the Gigabit network using nfs. When I try to mount I get: mount: old:/TERABYTE failed, reason given

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 have a quad core server in which I want to run 4 virtual servers. On this server I have a 1/2 terabyte raid 1 I have split between the 4 members that have the OS on it. I have raid 5 10 terabyte internal storage running on a 3ware 9690a card. I want to share this storage between the servers without partitioning it. Is this possible? -------------- next part -------------- An HTML attachment

Dear Experts, Could someone recommend good Linux software RAID primer. It would be good if it has good coverage of monitoring and dealing with failures. I inherited a couple of boxes with big bunch of software RAIDs each, and I even may have some problems, but I don't want to bother anybody with specifics unless I really hit brick wall, not just my own ignorance. Thanks in advance for all

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it

I'm setting up a computer with CentOS 6.4 and a mirrored software RAID. I would like it to be encrypted so I was wondering what the best configuration is. The only info I could find is http://lists.centos.org/pipermail/centos-docs/2008-October/001912.html but it appears to be a bit old and the info on the wiki ( http://wiki.centos.org/HowTos/EncryptTmpSwapHome ) doesn't seem to address

Hi, I've used mdadm for years now to manage software raids. The task of using fdisk to first create partitions on a spare drive sitting on a shelf (raid 0 were my 1st of 2 drives failed) is kind of bugging me now. After using fdisk to create the same partition layout on the new drive as is on the existing drive and then using mdadm to finish every thing up is a little tedious. Any

Hey List; I have no experience with software RAIDs; at work we only use hardware RAIDs and I'm looking to implement, probably a RAID 5 set up at home for a media server however I have a few questions; I have three 1TB drives in various places; one is inside a USB caddy, one is inside my PC and in is inside my existing media centre. Is it possible to add these three drives to another one to

Hey FLAC gang - Just thought you'd like to know CD Baby has switched to FLAC for archiving the 40,000 CDs we have in stock. Luckily HD space is down below $1/gig so we got a 6-terabyte RAID-5 box set up for about $7000. Got the FreeBSD boxes churning away night and day, ripping and archiving. I'll do a more formal press release for ya in a couple months as we're further along, but

What would you recommend for filesystems in the 50-500 terabyte range? (And yes, we do actually run a 70 TB at the moment, so I'm not asking just to annoy you; I'm genuinely

Hi, folks, This is a test post; to make it of interest, here's an issue you might want to be aware of, those with not brand new hardware. We've got a few Dell PE R415s. A 2TB b/u drive on one was getting full, so I went to replace it with a 3TB drive (a WD Red, not that it matters.) We got the system in '11. I built the drive - a GPT, 1 3TB partition, on an R320, from '12.
