High load averages copying USB
Problem as follows:
1) Plug in an external USB drive.
2) Mount it anywhere. Doesn't matter how.
3) Copy a few GB of data to the drive from a non-USB disk.
4) Watch the load average "climb" to 5.x, sometimes 10.x or more. Why?
This on an otherwise unloaded system. Doesn't matter how many cores, how
much RAM, 32/64 bit, etc.
Why should copying some files to a USB drive cause

Creating a bootable partition on a USB disk with syslinux
Hello,
I have a 2GB USB disk on key on /dev/sdb1.
I had created on it one partition (FAT16).
This partition holds all cylinders of the USB disk.
I want to create a bootable Linux USB disk.
For this, I tried:
syslinux -s /dev/sdb1
An than I ran:
fdisk -l /dev/sdb
Disk /dev/sdb: 2048 MB, 2048729600 bytes
64 heads, 62 sectors/track, 1008 cylinders
Units = cylinders of 3968 * 512 = 2031616

External USB Drive partitioning and formatting
Hi,
I just bought a Seagate 1TB USB drive thinking that I could create a
few partitions in it, format in ext3 fs, then configure bacula to
setup a backup server in my CentOS box and backup my windows and mac
clients.
I have plugged the drive and mounted in /mnt/usbdrive and is seen as
/dev/sdb1 by the OS. The output of df command is:
[root at Production ~]# df

USB external HDD error messages
Hi - relatively inexperienced user here. I installed CentOS 5.2
yesterday (http install via a mirror, worked brilliantly), as well as a
new Seagate 1Tb USB external HDD (from the new Xtreme line), for
backup/media storage.
Using fdisk I put two primary partitions on the Seagate, /dev/sde1 and
/dev/sde2 (roughly half the drive each). Then I used mkfs.ext3 on both
to create ext3 filesystems

Help with External USB drive on RH/Centos 5
Another issue to tackle - I have an external 1 TB drive (2 500GB on a RAID).
When I plug it into the server, it sees, via /var/log/messages, that a USB
device was plugged in, but that's it. fdisk -l doesn't see it. dmesg doesn't
do much, either. It is a Western Digital My Book II device.
I want to format it and use it for external storage, but can't until I get to
it.

QUESTIONS from EMC: EFI and SMI Disk Labels
All,
my apologies in advance for the wide distribution - it
was recommended that I contact these aliases but if
there is a more appropriate one, please let me know...
I have received the following EFI disk-related
questions from the EMC PowerPath team who
would like to provide more complete support
for EFI disks on Sun platforms...
I would appreciate help in answering these questions...

Mounting an external USB drive
With Centos 5.5, my external USB drive appears to self mount in
that the icon appears on the desktop and when I double click on
it, the files are there. However, I recall that I need to make
an entry in the fstab as well as some other changes.
When I do a
# /sbin/fdisk -l
I learn that the device is /dev/sda1 and the system is HPFS/NTFS
I am not sure what to enter into the file system

USB Thumb Drive Confusion
I am running CentOS 4.7. I have a USB flash (thumb) drive that has a
bunch of files placed there by Windows. I plugged it into the CentOS
machine, and when I listed the files under "/media/usb-name", there
was nothing there.
I created an empty file:
touch blah
and it showed up when I did list it.
I noticed, checking dmesg that it was attached to /dev/sdb.
So I did a quick

Building an install disk on a USB key, solved
Ok, there's been discussion, including, I think, on the wiki web page,
that syslinux is not correct. At any rate, after enough experimentation, I
have a working install on a USB key. The procedure is:
Using fdisk, partition your key: one partition, VFAT (type b, and toggle
the bootable flag), about 9M or 10M, and a second partition big enough to
hold a DVD. That should be type 83 (Linux

steps to add a new physical disk to existing LVM setup in new centos box?
Not a centos specific question here, but if anyone can save me from
shooting myself in the foot would appreciate any pointers.... I have an
older centos 4.7 box that I recently replaced with a newer one running
centos 5.3. I'd like to add the hard disk from the older one to the
newer one before I scrap it for good. I don't care about the data on
it, would just like the extra drive

Re: Disk partitions and LVM limits - SUMMARY
Thank you all for the help.
I'm writing this summary message because of people requests. I haven't tried
all of this. I just collected it and organized it.
You've got a big storage. Now what?
The short answer is: "Just connect it. It should work."
I'll play safe by saying that the following applies to <10TB storage. Some
people reported file systems of 80TB.

Re: Using diskOnKey as additional disk - is it possible with default configuration?
Mats,
Thanks for your trial; following your mail I tried it with hda; it
is the same, it does not work -
"fdisk -l" does not show hda.
Regards,
Ian

Failed to create /dev/loop0p* entries for partitions inside loopback devices
centos 6 failed to create entries under /dev for newly created loopback devices. Any one know why? and how to fix/workaround it?
The steps to duplicate is pretty simple
dd if=/dev/zero of=/tmp/deleteme bs=1M count=100
losetup /dev/loop0 /tmp/deleteme
fdisk /dev/loop0?? ## created partitions 1, 2, etc.
fdisk -l /dev/loop0? ## confirmed that the partitions do exist
mkfs.ext3 /dev/loop0p1 ## failed

Could not mount SATA disk as module scsi_hostadapter is not loaded, although present in modules.conf
Hi people,
I installed a via SATA controller in a CentOS release 3.8 (Final) - I
needed additional disk space. After the first boot, the kudzu service,
added the following line to /etc/modules.conf:
alias scsi_hostadapter sata_via
and I rebooted. After reboot in dmesg one can see:
scsi0 : sata_via
scsi1 : sata_via
