How does LVM decide which Physical Volume to write to?
...This isn't specifically a CentOS question, since it could apply for
any distro but I hope someone can answer it anyway.
I took the following steps but was puzzled by the outcome of the test
at the end:
1. Create a RAID1 array called md3 with two 750GB drives
2. Create a RAID1 array called md9 with two 500GB drives
3. Initialise md3 then md9 as physical volumes (pvcreate)
4. Create a new volume group called "3ware" with md3 (helps me
remember what controller the disks are on)
5. Use vgextend and add md9 to the 3ware volume group.
6. Add a logical volume filling the volume gro...

Accidentally nuked my system - any suggestions ?
Hi,
My workstation is running CentOS 7 on two disks (sda and sdb) in a
software RAID 1 setup.
It looks like I accidentally nuked it. I wanted to write an installation
ISO file to a USB disk, and instead of typing dd if=install.iso
of=/dev/sdc I typed /dev/sdb. As soon as I hit <Enter>, the screen froze.
I tried a hard reset, but of course, the boot process would stop short

Bootable Kernel
Hello,
Sorry to sound like a bad record, but I'm trying to figure out why I'm
getting "Bad gzip magic numbers" errors when ISOlinux is trying to
inflate the kernel. Right now I'm clueless as to what's wrong. I've tried
various kernels compiled on a few different platforms. Has anyone ever
seen this before? ANyone know where a better forum to ask this question
