Fighting some install issues with a new box
Folks-
I have had a machine dropped in my lap that I am trying to get CentOS
4.1 to run on as a first pass (the hope is for it to eventually run
Rocks -- http://www.rocksclusters.org , which uses CentOS 4.x as its
underlying OS).
The machine has 2 Opteron 250DP (2.4GHz) with 4 GB of RAM. It is using a
Tyan Thunder K8WE (S2895A2NRF) motherboard with an nVidia nForce chipset

Question about RAID 5 array rebuild with mdadm
I'm using Centos 4.5 right now, and I had a RAID 5 array stop because
two drives became unavailable. After adjusting the cables on several
occasions and shutting down and restarting, I was able to see the
drives again. This is when I snatched defeat from the jaws of
victory. Please, someone with vast knowledge of how RAID 5 with mdadm
works, tell me if I have any chance at all

Hi Kelly,
Try running 'iostat -xdmc 1'. Look for a single drive that has
substantially greater await than ~10msec. If all the drives
except one are taking 6-8msec, but one is very

Rsync slow with hard links
I am running rsync throuhg cygwin and trying to "mirror" two hard drives
(hd1 -> hd2). HD1 have tons of hard links (I will say about 2 millions)
because I do monthly backups and have about 13 folders and maybe about
150,000 files. Every month when I make a new snapshot I would also want to
mirror HD1 to HD2. I tried running
rsync -aH --progress -vv /cygdrive/d/ /cygdrive/e/

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it.

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one.
Here is an iostat example from a host within the same cluster, but without the RAID check running:

CentOS 7 grub.cfg missing on new install
Greetings -
The short story is that got my new install completed with the partitioning I
wanted and using software raid, but after a reboot I ended up with a grub
prompt, and do not appear to have a grub.cfg file. So here is a little
history of how I got here, because I know in order for anyone to help me
they would subsequently ask for this information. So this post is a little
long, but

zfs
Hi, folks,
testing zfs. I'd created a zpoolz2, ran a large backup onto it. Then I
pulled one drive (11-drive, one hot spare pool), and it resilvered with
the hot spare. zpool status -x shows me
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.

GRUB2 configuration for Xen 4 on Ubuntu Linux 10.04
Hello,
I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports
Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted
the Hypervisor and Dom0. The screen is always black after some kernel
messages rapidly go by. I think that I may pass the wrong parameters to the
kernel or Hypervisor with GRUB2.
Can any one share his/her working grub.cfg for GRUB2 with

C7 + UEFI + GPT + RAID1
Hi messmer,
seems that anaconda supports partitioned RAID devices. Disk selection
see one mdraid device and permits to create partition on it.

Controlling the order of /dev/sdX devices?
Hi
CentOS 5.4(final) 2.6.18-164el5PAE. I am trying to prevent removable
USB and eSATA devices from occupying /dev/sdX devices ahead of a 3ware
RAID controller. For example: at boot, if a USB drive and eSATA HDD
(connected to an LSI 1068E onboard controller, reflashed in "IT" mode to
handle hotplug devices) were both present, they would occupy devices
/dev/sdb and /dev/sdc, ahead of

Is that true? If I have a system with two disks, where device.map
labels one as hd0 and the other as hd1, and I swap those numbers, the
resulting boot sector will differ by one bit.

Recovering data from old corrupted file system
I have a corrupted multi-device file system that got corrupted ages
ago (as I recall, one of the drives stopped responding, causing btrfs
to panic). I am hoping to recover some of the data. For what it''s
worth, here is the dmesg output from trying to mount the file system
on a 3.0 kernel:
