Converting to Raid1
Have a CentOS 4.x 32 bit server running on a single 500M SATA drive.
What is easiest way to convert too RAID 1 on it? Anyone have a link?
Would be open to hardware or software just do not want to reinstall
the entire mess.

Possible bug with latest 7.3 installer, md RAID1, and SATADOM.
I'm seeing a problem that I think maybe a bug with the mdraid software on the latest CentOS installer. I have a couple of new supermicro servers and each system has two innodisk 32GB SATADOM's that are experiencing the same issue. I used the latest CentOS-7-x86_64-1611 to install to the two SATADOM's a simple RAID1 for the root. The install goes just fine but when I boot off the new

EXT3 fs error on RAID1 device
Hi all.
I have a Dell SC440 running Centos 4.4. It has two 500GB disks in a
RAID1 array using linux software raid (md1 is / and md0 is /boot).
Recently the root file system was remounted read-only for some reason.
The logs don't show anything unusual, presumably the file system was
read-only before anythng was logged. Running dmesg showed this error
repeated many times:

Hardware requirements
I don't seem to be able to find the necessary hardware
specs for an Asterisk server. What I have in mind is a
dedicated server to serve 50 or so people. All users
will use SIP phones and there will be an ISDN gateway
for outgoing/incoming calls. Do you have any
suggestions about the server specs (CPU, RAM, HD,
etc)?
Also, has anyone used Epigi Quadro ISDN gateway with
Asterisk? If so, what is

C7 + UEFI + GPT + RAID1
Hi list,
I'm new with UEFI and GPT.
For several years I've used MBR partition table. I've installed my
system on software raid1 (mdadm) using md0(sda1,sdb1) for swap,
md1(sda2, sdb2) for /, md2 (sda3,sdb3) for /home. From several how-to
concerning raid1 installation, I must put each partition on a different
md devices. I've asked times ago if it's more correct create the

Software RAID1 with CentOS-6.2
Hello,
Having a problem with software RAID that is driving me crazy.
Here's the details:
1. CentOS 6.2 x86_64 install from the minimal iso (via pxeboot).
2. Reasonably good PC hardware (i.e. not budget, but not server grade either)
with a pair of 1TB Western Digital SATA3 Drives.
3. Drives are plugged into the SATA3 ports on the mainboard (both drives and
cables say they can do 6Gb/s).

raid1 custom initrd and yum
OK sorry to hammer the list but one more question - having almost got the
drives mirrored and happy - since I have created a custom initrd that has the
raid1 drivers in it, do I now have to tell yum to ignore kernel updates? Will
the stock kernel render me unbootable?
Actually I am not 100% sure the initrd I created

Convert "bare partition" to RAID1 / mdadm?
I have a large disk full of data that I'd like to upgrade to SW RAID 1
with a minimum of downtime. Taking it offline for a day or more to rsync
all the files over is a non-starter. Since I've mounted SW RAID1 drives
directly with "mount -t ext3 /dev/sdX" it would seem possible to flip
the process around, perhaps change the partition type with fdisk or
parted, and remount as

Upgrading system from non-RAID to RAID1
I plan to upgrade an existing C7 computer which currently has one 256 GB SSD to use mdadmin software RAID1 after adding two 4 TB M2. SSDs, the rest of the system remaining the same. The system also has one additional internal and one external harddisk but these should not be touched. The system will continue to run C7.
If I remember correctly, the existing SSD does not use a M2. slot so they

Trying to mount RAID1 degraded with removed disk -> open_ctree failed
Hi,
I have setup a RAID1 using 3 devices (500G each) on separate disks.
After removing one disk physically the filesystem cannot be mounted in
degraded nor in recovery mode. When putting the disk back in the
filesystem can be mounted without errors. I did a cold-swap (powercycle
after removal/insertion of the disk).

RAID1 building via hardware
Hi all,
I?m trying to create a RAID1 on a machine. I?ve already configurated BIOS (mother board, Intel, S500VSA SATA) so as to build RAID1 via hardware. However on CentOS Installer, when I reach "disk setup" screen, it shows up 2 devices (/dev/sda and /dev/sdb).
Is this right (both devices being showed)?
How should I proceed on this moment? If I create the
