similar to: Mirroring Disk (Apologies for the new thread I deleted the original)

OK all my HP Microserver is purring away nicely now, as usual I looking for the rainy day. Although my data is on a RAID 5 array my OS is on a single disk. Any suggestions as to the best way to have a copy of my OS on an attached USB Drive? Been considering dump and restoring to the usb disk periodically? or maybe something using LVM or maybe creating and breaking a RAID 1 array? Just not sure

Hello. A couple of years ago I installed two file-servers using kickstart. The server has two 1TB sata disks with two software raid1 partitions as follows: # cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb4[1] sda4[0] 933448704 blocks [2/2] [UU] md0 : active raid1 sdb1[1] sda2[2](F) 40957568 blocks [2/1] [_U] Now the drives are starting to be failing and next week

Has anyone installed a high I/O application such as an email server on SSD drives? Was thinking about doing two SSD's in RAID1. It would solve my I/O latency issues but I have heard that SSD's wear out quickly in high I/O situations? Something like each memory location only has X many writes before its done. Just wandering if anyone has tested it and if newer SSD's are better about

Hi, we have SunFire X4140 connected to Dell MD1220 SAS enclosure, single path, MPxIO disabled, via LSI SAS9200-8e HBA. Disks are visible with sas-addresses such as this in "zpool status" output: NAME STATE READ WRITE CKSUM cuve ONLINE 0 0 0 mirror-0 ONLINE 0 0 0

Hello I have a strange issue, I''m having a setup with 24 disk enclosure connected with LSI3801-R. I created two pools. Pool have 24 healthy disks. I disabled LUN persistency on the LSI adapter. When I cold boot the server (power off by pulling all power cables), a warning is shown on the console during boot: .... WARNING: /pci/path/ ... (mpt0): wwn for traget has changed

Hi Folks, When I boot ISOLinux, the locally attached disk is visible but the PATA 40 Gig in a USB attached enclosure is not. The locally attached disk has no bearing on what I am doing and to avoid confusion will not be mentioned again. Everything is happening on the 40 Gig. Let me explain. The goal is: Copy an installation iso to the disk, boot the disk and install it on that disk. I have

List Readers - I have a Dell server that uses the Perc 6i controller and had 5 1Tb disks installed (1 for OS and the other 4 in a Raid0 for a large storage pool). The owner of the server wanted me to swap out the 1Tb disks for 2Tb disks - easy enough I thought, but I ran into some issues trying to clone the OS disk to the new 2Tb disk, so I just did a re-install. So basically we now have 5 2Tb

hey, I'm seeing an Oops when nouveau loads (see below). I've verified that this is because both device->chip and device->name are NULL prior to the strncpy()s at the end of nvkm_udevice_info().

Hello, I have two disks sda and sdb. One of the was broken so I have changed the broken disk with a working one. I started the server in rescue mode, and created the partional table, and added all the partitions to the software raid. *I have added the partitions to the RAID, and reboot.* # mdadm /dev/md0 --add /dev/sdb1 # mdadm /dev/md1 --add /dev/sdb2 # mdadm /dev/md2 --add /dev/sdb3 # mdadm

Hello, I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at power off, plugged in a new one, partitioned it (to 110GB, by error), and added it to btrfs. I tried to remove the missing device, and it said "Input/output error" after a while. Next attempts simply gave "Invalid argument". I repartitioned, rebooted the system, and made the partition grow:

Tired of "little problems" trying to keep 7 drives working in an old desktop computer, I'm considering an external SATA drive enclosure with a controller card based on the Sil3124. http://www.ipcdirect.net/servlet/Detail?no=152 I'm a bit concerned about long-term support, namely that the company's driver page only lists drivers through RedHat 4.

Greetings - Ok, I have my CentOS 7 KVM host system installed and I want to be able to boot the system from either installed drive if one of them fails. My objective is to have the following layout for the two 3 TB disks. sda1 /boot/efi sda2 /boot sda3 RAID1 with sdb3 sdb1 /boot/efi sdb2 /boot sdb3 RAID1 with sda3 The system is installed and boots from sda[1,2] and md127 (sda3 and

Hello all, I have 3 Supermicro 1u servers, each with dual 250gb SATA drives. I have a server with CentOS 5 64bit setup for pxebooting and kickstart installs. I have a kickstart install file that doesn't specify the disks specifically. It works like a champ, and the operating system installs and completes. I have a kickstart install file that specifies the disk devices (sda,

I'm posting here before going through all the fun to do up a real bug report to see if anyone else has seen this behavior. I have two identical Dynex external USB3 drive enclosures with identical 3TB drives in each enclosure.

Hi Everyone, I started a social networking site and I am getting ready to go live next week. I have limited fund as I am not funded yet (although hopefully soon). I have an extra Mac Pro (I know, how can I possibly call a Mac Pro dual 2.8 quad core with 16gb RAM extra). So Mac Pro quad Core, 16gb RAM, 4 x 1tb RAID level Seagate drives. I was going to load CentOS 5.4 on it, web, mysql

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

Lol - spinning disks? Really? SSD is down to like 50cents a gig. And they have 1TB disks... slow disks = you get what you deserve... welcome to 2015. Autolacing shoes, self drying jackets, hoverboards - oh, yeah, and 110k IOPS 1TB SamSung Pro 850 SSD Drives for $449 on NewEgg. dumbass -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf
