I created a 4GB disk image for a virtual machine in Xen. (I have root on the physical box, so please don't tell me to contact my VPS provider!)
The disk was filling up, so I took the advice online and created a 6GB file with dd (zero-filled), cat'ed it to the end of my disk file, and then...
[matt@babe centos]$ sudo resize2fs -f ./cent.img
resize2fs 1.39 (29-May-2006)
resize2fs: Bad magic number in super-block while trying to open ./cent.img
Couldn't find valid filesystem superblock.
Of course, fsck won't take a disk image, only an actual partition. And I can't mount it, since I get the same error about a bad superblock.
The VM actually boots up fine, but it only sees 4GB of what's now a 10GB file.
I can use losetup to mount it on a /dev, but still get fsck errors:
[matt@babe centos]$ sudo fsck.ext3 -b 8193 /dev/loop3
e2fsck 1.39 (29-May-2006)
fsck.ext3: Bad magic number in super-block while trying to open /dev/loop3
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
I don't know what blocksize was used, so I don't know where to look for a superblock... (I'm out of my league on fsck'ing virtual disks.)
The thing boots fine and is non-mission-critical right now, so worst-case, I can just mount it, rsync the data to the host, and then set up a new machine and rsync that in... I'd just rather not go through that hassle if I don't have to.
can a Xen disk image be converted to a diskpartition?
Someone is asking whether I can host his disk image at his current host, which he is leaving for poor I/O (wonder why that would be ). I can host a diskimage, but I don't like diskimages (slow, and 100GB isn't very 'comfortable' either). Is there any way out there to convert a disk image into a normal partition?
XP Home, Verizon DSL, AVG, ZoneAlarm, CoffeeCup FTP, FileZilla FTP
So this all started about 5 days ago and I cannot think of anything that I did to associate this issue with. I'm very computer savvy and no one else uses this computer except for me (to help move things along faster). Essentially what happens when I start CoffeeCup FTP or FileZilla FTP (testing to make sure it wasn't just a problem with CoffeeCup FTP) and try to upload image files it fails, not the upload itself.. but somehow the image files are corrupt (no they're not CMYK, they're RGB). So it shows the file on my server, correct size, no error messages. However, when I go to the image URL it just shows the image URL where the image should be. I then restart CoffeeCup FTP and everything uploads properly. I've checked the lines on DSLReports.com, I've checked ZoneAlarm to make sure that I didn't somehow accidentally click no to something (which is unlikely). I keep my computer very clean and very organized and very up to date so it would be more helpful to me if someone could share some ideas of something that could happen that's not of my control. Could this possibly have anything to do with SP3 (the only thing I can recall being a change on my computer).
i have install 3-4 dell PE server withn cenots 5, on the server there is only the OS, i have reboot the server and it work fine, after 4-5 days the system was unstable rebooting it i have note that can mount the partition, i have check the /etc/fstab and i have found that the fstab was corrupt, there are a lot of entry for /dev/shm, why happend this? how can i recove the fstab?
i have a strange issue on my centos 5, the fstab get corrupt, we have reinstall the OS and with the server empty it get corrupt again, the same problem on a second server, seem that is add /dev/shm line, like this one:
I have two partitions on my hard drive, each have an installation of windows XP, the old partition got corrupt and I can no longer boot windows from it, however I am able to see the files when on the other partition, the problem is I am unable to access the files.
Is there anyway I can get permissions to delete/move those files?
O/S was corrupt so I had to do a reload on a new drive. I'm trying to mount original drive (already connected as 2nd) but it is not showing up in df -h

I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
The server is displaying these errors when I tried to do an FSCK: Bad inode IO ext3-fs error (device(8,3)) IO Failure
I am having a new primary installed and old primary set as 2nd drive. I need to recover the cpanel domain accounts from this 2nd drive after I mount it with the method below:
mkdir /backup mount /dev/sdb1 /backup
However, how do I actually recover these accounts in an automated process via whm? I've done this before with the same matter (corrupt primary drive, mount as 2nd, etc) but cannot exactly remember the proper steps.
I have a dedicated box and I started getting Input/output errors today.
I tried: # fsck fsck 1.40-WIP (14-Nov-2006) e2fsck 1.40-WIP (14-Nov-2006) /dev/hda2: recovering journal fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried: # fsck -a -t ext3 /dev/hda2 fsck 1.40-WIP (14-Nov-2006) /dev/hda2: recovering journal fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?
I am not sure if many of you have been getting this same spam. But I've been getting spam about sexual topics and the email is just an image with words written on it.
Sometimes the email has words too such as what is written below.

I was wondering if you know of a way to block those emails.
I installed imagemagick perl module but it is still giving off this error

I have developed website which will allow user to upload 1-2 photos and also allow to see other users photo and rate them. For this I have planned to go for VPS. I am also thinking of another alternative of using image hosting service, where I will keep all user photos on image hosting server and embed links given by image server in my webpage.
Now my question is.
1) Using image hosting is faster(respone time for each user) than VPS?
2) How exactly using image hosting works. when user request web page from my server, will my server go and fetch entire image from image server and then send final result to user brower?
where I can host images for my site. It will be thousands of smaller image like 5k - 30k. I am looking at free sites like imageshak. They say in their terms of service that I can host images for my site as long as I don't host all my images. So do you think that I could put like 20 thousand images on their site? These images would not get accessed too much so it won't slam their servers or anything.
I haven't been able to find much about this searching, but are people using NAS storage to deliver website images? I've never used NAS before and am not familiar with their performance.
My goal is to block hotlinking of fullsize images and display a image when they attempt it... but allow clickable thumbnails to be shown. For some reason the following isn't working...
My htaccess looks like this:
RewriteEngine On RewriteBase /images
#Allow if it's not from another website RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} ^[url] RewriteCond %{HTTP_REFERER} ^[url]
#Allow if it's the hotlink.gif RewriteCond %{REQUEST_FILENAME} hotlink.gif [NC,OR]
#Pass through thumbnails or hightlights as-is RewriteCond %{REQUEST_URI} .thumb.jpg$ [NC,OR]
#Return an anti-hotlink gif in place of any visual media RewriteRule .*.(jpe?g|gif|bmp|png)$ css/images/hotlink.gif [R,L,NC]
i have a forum site which is running on a vps 45gb space and 2000gb put i would like to offer my members a means to upload images small files max 5-10mb just with in the site but i would like to use a totally new server are there any shared host that will allow this has i will use a scrpit has well on it
i have set up a sever with certain software exactly the way i want it. However, there is some extra stuff i need to install on it.
I am running Centos 5.1 and would like to run some command possibly via ssh which would create an entire image of the server in a disk format such as ISO and then if need be, reinstall the basic operating system and restore the ISO back up if need be.
Is this possible?
If so how and how would i restore the image as well?
I have started a new image hosting website and currently i alloted 7 GB Disk Space and 30GB BW. I know it will not be enough after the site get famous. So which host i can go for to be in a safer side with my image hosting website?
I am having a win 2003 server with a static ip and i have hosted 2 web sites in the iis server but no images are been displayed is it something to do with the designing of the site or some problem in my hosting,
