similar to: RAID advice? and KVM advice?

I manage a small server that I back up weekly. I do this by making a tarball of relevant files then transferring it over the local subnet to my station (Fedora 11), whereupon I burn it to DVD. There is no optical burner on the server. The tarball amounts to a bit under 5 gigs. Recently I've started getting an error telling me to try PASV or PORT first. I use the gFTP client on my

Hello All, As you can see below I am having a problem checking for updates. This happens repeatedly. I have to kill the process then rerun. I have tried "yum clean all" but no joy - the process hangs again on "extras" - see second listing below. Suggestions?

I just installed 5.3 about a week ago, fairly minimal install, x86_64 platform... then upgraded to 5.4 this AM, and just installed firefox $ sudo yum -y install firefox ..... Installed: firefox.i386 0:3.0.12-1.el5.centos firefox.x86_64 0:3.0.12-1.el5.centos $ firefox Could not find compatible GRE between version 1.9.0.12 and 1.9.0.12. huh?

Greetings- I'm about to embark on a new installation of Centos 6 x64 on 4x SATA HDDs. The plan is to use RAID-10 as a nice combo between data security (RAID1) and speed (RAID0). However, I'm finding either a lack of raw information on the topic, or I'm having a mental issue preventing the osmosis of the implementation into my brain. Option #1: My understanding of RAID10 using 4

I have been reading lots of stuff but trying to find out if a raid10 2drive setup is any better/worse than a normal raid 1 setup....I have to 1Tb drives for my data and a seperate system drive, I am only interested in doing raid on my data... So i setup my initial test like this.... mdadm -v --create /dev/md0 --chunk 1024 --level=raid10 --raid-devices=2 /dev/sdb1 /dev/sdc1 I have also read

Hello, I was wondering if someone could help me, I'm putting together a Server for personal use, I want to virtualize a few servers(mail, web, ssh) and use it as a NAS, but I have a question if I can use Multiple RAID Arrays using the following HW: Intel Xeon Quad Core X3430 ASUS P7F-M LGA 1156 - LSI MegaRAID(integrated) - HighPoint RocketRAID 2640x1 2 Hitachi 500GB HDDs 4 Hitachi 1TB HDDs

I got the email that a drive in my 4-drive RAID10 setup failed. What are my options? Drives are WD1000FYPS (Western Digital 1 TB 3.5" SATA). mdadm.conf: # mdadm.conf written out by anaconda MAILADDR root AUTO +imsm +1.x -all ARRAY /dev/md/root level=raid10 num-devices=4 UUID=942f512e:2db8dc6c:71667abc:daf408c3 /proc/mdstat: Personalities : [raid10] md127 : active raid10 sdf1[2](F)

The relevance of this question can be found here: http://aput.net/~jheiss/raid10/ I read the mdadm documents but I could not find a positive answer. I even read the raid10 module source but I didn't find the answer there either. Does someone here know it? Thank you!

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so

Hello... I have a server with 4 x SCSI drives and I would like to install Centos 4 (or 5) onto a software RAID 10 array. Do you know if this is possible? I noticed that under the Centos 4.92 beta, RAID 5 is an option but for some reason RAID 10 is not listed. There does appear to be a RAID 10 module.... /lib/modules/2.6.9-42.0.8.ELsmp/kernel/drivers/md/raid10.ko More info I found here:

I'm going to rebuild my system at home soon, and was planning to mirror two drives. However, I was just looking up something about RAID, and on wikipedia found some information about the Linux MD driver, and "near" and "far" RAID10. Anyone have some opinions about them? mark "or should that be how many opinions do folks have about them?"

hi everyone I've just configured a simple raid10 on a Dell system, but one thing is puzzling to me. I'm seeing this below and I wonder why?

Hello all, Testing stuff virtually over here before taking it to the physical servers. I found a shortcut for creating a software RAID 10 ("--level=10"), device in CentOS 6. Looking at the below, I don't see anything about a shortcut for RAID 60. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm l/Storage_Administration_Guide/s1-raid-levels.html Is RAID

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host

How slow and how reliable is software raid 6 on CentOS 5. The system I'm going to use is A socket 939 dual core Athlon, 4 gigs of ram and a 3ware 7506-8 controller. Its mostly going to be used for storage (Movies, MP3s etc.). Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t
