Jun 21, 2011I was using Terminal and browsing a directory in my home folder. My "home" directory is located on "/dev/sdb1". When in Terminal I typed "ls" in one of my directories and the output was garbage. The output didn't show the files in the directory. I think it said something like, "input/output error". Unfortunately, I didn't write the exact error down. Instead I rebooted.The hard disk with the problem is:

Ubuntu :: Write Speed For Hard Disk And / Or Partitions
May 10, 2010I have what seems to be a hard disk Write speed problems with my first hard drive. Timing the cp command of a 700 Meg file takes about 8 secs from disk 2 to 3 but takes 25 minutes from disk 2 to disk 1.
Here are the details:
Kubuntu 9.04 (Kernel 2.6.28-15-generic)
Hard Disk 1 : /dev/sda (WDC WD2500KS-00MJB0)
Partitioned
/dev/sda1 ext3 / 10 Gigs
/dev/sda2 extended 222 Gigs
/dev/sda5 linux-swap 2 Gigs
/dev/sda6 ext /home 220 Gigs
Hard Disk 2 : /dev/sdb (WDC WD2500AAKS-00F0A0)
Partitioned :
/dev/sdb1 ntfs 16 gigs
/dev/sdb2 xfs /home/eric/data_drive 216 Gigs
Hard Disk 2 : /dev/sdc (ST3500320AS)
Partitioned:
/dev/sdc1 xfs /home/eric/data_drive2 465 Gigs
By doing 'time cp ...sdb1/test.avi ...sdc1' takes about 8 seconds and same vice-versa. the command 'time cp ...sdb1/test.avi ...sdb1/test1.avi takes about 11 seconds and the same holds true if sdc1 is used But copy sdb1 or sdc1/test.avi to either sda1 or sda6 and it takes 25 minutes. Same problem if I copy from the same drive partition (sda). I have booted a livecd Knoppix 6.2 and the same problems happens.. So safe to say it's not Kubuntu. The only thing that is left to do is backup and reformat the partitions as XFS and try again. I also did a full smartcontrol Extended test and no errors. Checked all the various logs and nothing found.

Hardware :: Way To Check Overall Size Of Hard Disk
Jan 22, 2010Is there any other way to check the overall size of the hard disk other than just fdisk -l? This is because the cloud server that my company has purchased is supposed to have 50GB of hard disk size,It shows that it has two SCSI drives, only both summing up to 50GBs. So what is the second SCSI drive, and why is it divided that way? dev/sda and dev/sdb???

Jul 12, 2010I am having a problem with my CentOS based server where the hard drive speeds are incredibly slow for both of the hard drives installed -
Code:
Timing cached reads: 16512 MB in 2.00 seconds = 8272.92 MB/sec
Timing buffered disk reads: 12 MB in 3.01 seconds = 3.98 MB/sec
I have looked around but do not understand the complexities of rebuilding kernel etc so would need some assistance. I have checked IO_support and it is set to 0
Code:
Here are the results for hardware installed after a quick lspci -v

If there are any noticeable incompatibilities here and how I could work to speed this up. I only have SSH access and could possibly get a KVM on it as it is currently locked up in a DataCenter.

I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?

View 1 Replies View RelatedServer :: New Server Installs Require Whole Hard Disk?
Sep 1, 2010I have decided to try to run a web server, with a view to possibly, eventually, hosting my own website.To test the water I downloaded ClearOS and SME Server with a view to installing on a spare partition and trying them out.But, both installers seem to require the whole HDD to install into. Both installers have a warning saying that all partitions and drives attached to the PC will be erased in order to 'initialise' the HDD.
I must've installed 100 linux distros and i've never seen this before, including CentOS 5.5, which ClearOS is based on.Why is this the case? Is there any way I can install alongside another linux installation?? I have tried vbox but it doesn't offer a proper sandbox really as there is only one NIC.
General :: Use Hard Disk Image Like A Regular Hard Disk?
Apr 6, 2010If you have a hard disk image (including partition table, multiple partitions,...), is it possible to let Linux treat it as a regular hard disk?
By "regular hard disk" I mean I would like to have the image show up as, for instance, /dev/hdx and its partitions as /dev/hdx1,...
(I know I can mount one of the partitions in the image using "mount -o loop,offset=x ..." but I don't really like this option.)

View 6 Replies View RelatedServer :: Can't Run Script After Hard Disk Was Filled
Dec 13, 2010I have a MythTV backend setup with videos also transcoded to a directory for streaming to my Roku frontend. A week ago, the backend had an issue that caused the hard disk to fill up, which borked a bunch of things up. I've since repaired the damage (and learned a lot about log size settings for logrotate.d). Anyway, my last problem is that a script I wrote to compare the files in the transcoded directory to the MythTV base directory and delete files no longer relevent doesn't work anymore. I get the following error when run by any user, including root:
Code:
bash: ./roku-autoexpire.sh: /bin/bash: bad interpreter: Permission denied
The script worked fine before the hard disk fill, but now I can't seem to get it to work. Both the original MythTV partition and the streaming partition are XFS. Here's the pertinent lines from fstab:
Code:
/dev/sdb1 /var/www/mythroku xfs defaults,auto,grpid,exec,user 0 0
/dev/sdc1 /mnt/mythtv xfs defaults,exec,user 0 0
Permissions for the directories are the following:
Code:
drwxrwxr-x 2 mythtv mythtv 16384 2010-12-13 19:21 /var/www/mythroku
drwxrwxr-x 2 mythtv mythtv 20K 2010-12-13 20:13 /mnt/mythtv
I tried fiddling with the mount options for the partition, but that didn't seem to solve the problem.
