similar to: Best configuration for encrypted software RAID 1?

Does software raid 1 compare checksums or otherwise verify that the same bits are coming from both disks during reads? What I'm interested in, is whether bit errors that were somehow undetected by the hardware would be detected by the raid 1 software. Thanks, Nataraj

Hi, I have 2 identical xSeries 346 with 2 identical IBM 72GB scsi drive. What i did is install the centos 4.2 serverCD on the first IBM and set the HDD to raid1 and raid0 for swap. Now what i did is get the 2nd HDD in the 1st Server swap it with the 1st HDD in the 2nd Server and rebuild the Raids. The 1st server rebuild the array fine. My problem is the Second server, after rebuilding it and

Hi everyone, I added a page under the HowTos for Encryption, and then added a guide for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on LVM, when you already have partitions setup. http://wiki.centos.org/HowTos/EncryptTmpSwapHome Regards, Max

Hello all. I have a server with a linux software raid1 setup between two drives of the same model....one hard drive as primary ide master and second hard drive as secondary master. Now primary master hard drive is displaying a lot of SMART errors so I would like to remove it and replace with another drive....different brand but same size. Partitions are /dev/md0 till /dev/md5. I think I know what

I just did a clean net install of CentOS 6.4 and when I run virt-manager it says that qemu-kvm is missing, but when I try to install it with yum it says that there isn't a package with that name. Is something wrong with my configuration? Or what is causing this package to appear as not available? Thanks, Dave

How can I prevent the laptop from sleeping when the lid is closed. I tried messing with the settings in gnome-power-preferences but that doesn't seem to prevent it when no one is logged in. Any suggestions? Thanks, Dave

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. CENTOS 7.6.1810, fresh install - use this as a base to create/upgrade new/old machines. I was trying to setup two disks as a RAID1 array, using these lines mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/sdb1 /dev/sdc1 mdadm --create --verbose /dev/md1 --level=0 --raid-devices=2 /dev/sdb2 /dev/sdc2 mdadm --create --verbose /dev/md2 --level=0 --raid-devices=2

I have a SUSE 9.0 box with a software raid. It consists of 6 IDE drives and three different controllers The OS is on a separate drive. What I want to do is put a new boot drive in load Centos on it. Then I want to be able to mount the raid without loosing any of the data on it. What information do I need from the SUSE OS (raid info etc...) to tell Centos how to recognize it? The data is backup on

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

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

Hi, I am using a digitized voice with a vocabulary of some 350.000 words. Converting them from WAV to Speex obviously cut down the size a lot, but I find that some more compression could be done. Specifically I collect the resulting files in one big container file, and that one compresses quite well (from about 600MB to about 130MB). I expect that is due to redundant data in the headers

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
