similar to: External USB disk devices cause high load

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

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

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 Filesystem 1K-blocks

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

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.

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...

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

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

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

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

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.

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.

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

it seems like I keep running into a wall.

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 Vendor: ATA Model: SAMSUNG HD080HJ Rev: WT10 Type: Direct-Access
