similar to: 3TB External USB Drive isn't recognized

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

[previously sent to rhelv5 list, apologies to those on both] I've got a problem I can reproduce easily enough, but really I fail to understand what's going wrong. I've got a 5.3 Dom0, which is running three guests. One is Fedora 10, that runs with local flat files, and works fine. One is Nexenta 2 (opensolaris-based), and that runs off of physical partitions, and seems to work

I have an Athlon with about 10 HDDs plugged in, primarily to do Disk2Disk backups. Some drives are PATA, some are SATA, some are USB. A strange concoction, but it's been relatively stable for some 4-5 years, despite numerous upgrades and so on. It's been running CentOS 4 for a long, long time. (years) Recently, I've started to have problems with its stability, and after 2 weeks

Hi, I''ve got similar problem - after HW failure - two of three disks became unavailable and now I''m unable to btrfsck.

Hi, all: Two questions. Environment: Ubuntu 12.04 1) mount: unknown filesystem type 'smbfs' With default Samba 2:3.6.3-2ubuntu2.3 installed, all the following 3 commands failed: a) $ sudo mount -t *smbfs* -o username=MYNAME,password=MYPWD //mybooklive/myfolder /media/smb/ mount: unknown filesystem type 'smbfs' b) /media$ sudo mount -t *cifs* -o username=MYNAME,password=MYPWD

Hello, I just upgraded from Xen-3.3.1 to Xen-4.0.0. System is Gentoo, Hardware is DualCore AMD Athlon, 8GB RAM. The kernel was upgraded from OpenSUSE 2.6.27.29-0.1.1 to Gentoo-2.6.32-xen- r1. The first boot failed with an OOM error during kernel/initrd load, so I adjusted the dom0_mem option and had to increase it''s avalue from 256M to at least 400M until the dom0 could boot. At all

dmesg output after a resume from a suspend. the device in question was /dev/sdb mounted on /home. after a device failure to resume properly, the link is then reset by the kernel but comes back as /dev/sde. /dev/sdb disappeared entirely, and is now referred to as sde. attempted to remount rw of sde, seemed to succeed, mount/mtab said that it was rw now but i couldn''t write to the volume

Hi Gang. I installed CentOS last night and the sound card detection failled to detect the sound card. I have a Asrock K8NF6G-VSTA mother board, with a nVidia NF6100-405 chip set. I have tried various live distro's and I ran Fedora 7 on it for just over 2 weeks and none of them detected the sound card. I'm a newbie to Red Hat based distributions but have been using Mandriva for

Hello, on a fs with 4 disks, raid 10 for data, one drive was failing and has been removed. After reboot and ''mount -o degraded...'', the fs looks full, even though before removal of the failed device it was almost 80% free. root@fs0:~# df -h /mnt/b Filesystem Size Used Avail Use% Mounted on /dev/sde 11T 2.5T 41M 100% /mnt/b root@fs0:~# btrfs fi df /mnt/b Data,

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

Hi everybody, we are using a btrfs RAID 1 with four 2TB hard drives on a Debian 7.1 (Kernel 3.9.6). After about one year of working, there was an error in messages log and the filesystem was mounted read-only. After that I restarted the system but that doesn''t fix the bug. The btrfs-filesystem couldn''t be mounted. I attach four logs: -> when the error occured ->

- RAID10 btrfs volume consisting of 4 disks. - One disk failed, was replaced, resync started (`btrfs dev add /dev/sdf /srv; btrfs dev del missing /srv`) - Another disk failed before resync was done. Disk was replaced, resync restarted. (`btrfs dev add /dev/sdc /srv; btrfs dev del missing /srv`) Naturally I don''t expect it to recover from 2 failures, but doing the attempt was

I'm trying to figure out why 2 machines have a "hard I/O lock" on the HDD when running EL6. I have 4 identical machines, all were stable with EL5. 2 work great with EL6, 2 do not. I've checked momtherboard BIOS versions and settings, SAS controller BIOS versions and settings, they are the same between the working and non- working systems. When booting a non-working system,

I just tried this with CentOS 5.3 as well, and got exactly the same symptoms and dmesg output. (As a point of comparison, Ubunu 8.04 on my work laptop is able to access the drive.) Obviously "not detected" is a misapprehension, though I'm puzzled why "lsusb" doesn't show it. The device is there even though the partition table can't be read. ---------- Forwarded
