On a freshly installed Ubuntu server 11.04 I noticed that the /dev/disk/by-path directory (and of course it's contents) are missing:

One of my raid disks (was a software raid5 with 4 drives) failured. I wanted to buy a new 1.5TB harddisk anyway so i i copied all the Raid data onto the new disk and disconnected the old ones. But then the new Disc crashed right before i could mirror it with another 1.5TB disk. So i need to reassemble my old Raid 5 now. I connected the drives in the former order except the first one, because this was the failed disk. The problem is, mdadm can't find the raid, no superblocks. Fdisk doesnt show mdraid superblocks, too. But fdisk has never showed superblocks. The thing is, this raid was crypted, but i crypted the /dev/md0, so this doesn't affect anything here, or?
some infos:
Code:
server:~# mdadm --misc -d /dev/sda
mdadm: option -d not valid in misc mode
server:~# mdadm --misc -t /dev/sda
[code]....
Disk /dev/sdc doesn't contain a valid partition table But fdisk always said there is no valid partition table and the raid was working.
My raid array has failed. I have two disks /dev/sda and /dev/sdb./dev/sdb has failed and I could not rebuild the array(madm returned that the device is busy) so I rebooted the machine. After that, the whole sdb disk went missing, as it now only shows sda in fdisk -l.Did the disk went totally dead or my raid glitched?

I had ubu 904 and vista installed on an 80gb drive, i had a spare 80gb drive also. I setup a raid0 config in my bios, then installed ubu9.10 onto it. All was fine until the very end, and then it said grub failed to install.
So i rebooted, and im left with a blinking cursor. How do i install grub? Ive installed ubu a few times now and never had an issue so now im lost.
so I just installed Squeeze Alpha1 amd64, dual boot with MS Vista using Grub. Everything seemed fine, but I'm apparently missing about 40GB of space. It should be set up as so:
101GB NTFS /dev/sda1 - Vista
12GB NTFS /dev/sda2 - HP Recovery
45GB ext3 /dev/sda3 - / Debian squeeze

I have a dual boot machine (Win XP + Ubuntu 9.10 on separate physical drives) which was working fine. I now want to replace the Ubuntu 9.10 with LinuxMCE which is based on Ubuntu 8.10. Using the LinuxMCE install disk, I did a fresh install of Ubuntu 8.10 over the top of Ubuntu 9.10 (repartitioning the whole drive). On reboot, I now get a Grub "no such disk" error. I have run the boot info script which produced the following RESULT.txt:
Code:

After buying a new PC, I decided to "reorganize" my former PC as follows:Initially it has been a dual (SATA) disk dual boot PC- one disk for each OS, while XP was fully installed on a single NTFS partition. Using Gparted I shrunk the XP partition, and created some Linux partitions. I've verified that the XP partition (sda1) is bootable. Afterwards, I removed the other (former Linux) disk from the computer. While doing so, I had to temporarily disconnect cables from both drives. Finally, I fresh installed Mint 9 (Ubuntu 10.04 derivative), on my pre-prepared Linux partitions. Installation completed flawlessly, and during the install, I've noticed that GRUB2 has been installed on sda. Rebooted and got "Disk boot failure" error.
I've checked the BIOS and noticed that the (single) drive was not recognized.
I manually tested from the BIOS and located the drive as IDE3. Saving the new configuration (F10) and rebooting- the HD gain is not identified (the CMOS battery is fine- keeps time).
Booting a live CD I can see and access all above partitions.
How can one create an alternate disk or boot path on a ubuntu server? I have a new server running 9.10 and have a full backup of an old server which had all the configuration and installed softwares, etc. Instead of trying to reinstall everything and configure it the way it was, I was thinking of adding another disk to the server, mount it and then hopefully be able to boot it from there. I don't have any LVM or mirroring setup but was hoping if I can specify a secondary boot path when the server boots up, if it fails I should be able to go back to the current one.
View 5 Replies View RelatedI have experienced a failure in one disk in my 4 disk software RAID10setup, but a straightforward rebuild is thwarted by the fact that twoof the other disks are considered non-fresh and hence get kicked outof the array. This of course prevents the array from starting up.Here's more detail about my setup:I have 4 2TB SATA disks in RAID10.

Company laptop HP Compaq 6710b, NTFS on hd0, Win7 installed. BIOS allows boot from USB drive, so wanted to use Ubuntu with no influence on laptop (no disconnecting internal drive, no dual boot, etc). Performed an install from CD to an USB drive making a JFS partition mounted on / and a swap partition. The installer made the JFS partition bootable (boot flag is set) as I asked. On first boot I got:
error: hd0 out of disk.

I own a web server (centos 64bit with cpanel on it) and my datacenter add me a second hard disk and i want first to locate from ssh where is it (the path) and then to copy my mysql folder /var/lib/mysql to the new disk and have it like this /new/mysql on the second disk.
View 8 Replies View RelatedI've run the install to hard drive program three times over and each time I get "disk boot failure". I believe I've got Grub to install to the mbr but I am not sure.
System:
Barton 3200+ with 1GB of DDR1
Asus A7V333
High Point hard disk controller
other items
All the hard drives are hooked to the High Point controller. It recognizes all of them that have power hooked up and read/writes to them. Two have 98SE installs, the third is where I'm trying to install Fedora 12 to get away from some problems I'm having with 98SE.
The BIOS is set up to boot from the "SCSI device" which means it's booting from the High Point controller. The High Point lets me set a boot mark, which, when set to the Fedora drive, yields the disk boot failure no matter what I do to it.
I have an SiI hardware SATA RAID card, with two 500GB disks in mirrored RAID configuration. When I first plugged them in and set it up, things seemed to work ok, but on boot the raid controller told me that the RAID needed rebuilding, and it would happen automatically after POST. So I didn't worry about it, and the drive mounted fine, and it's been that way for years. I just went in and manually on-line rebuilt the RAID in the controller's BIOS, and now when I boot into Ubuntu, both disks show up in fdisk, but neither show up in /dev/disk/by-uuid. Am I missing something?

[Code]...
1. I dont undestand what "if ! echo $PATH | /bin/grep -qE "(^|:)$1($|:)"" this if statement actually comapres??
2. Also what is the difference between PATH=$PATH:$1 & PATH=$1:$PATH
I was wondering if we could cd in the directory of the PATH variable. For example, if I type in echo $DISPLAY. It will give me /tmp/launch-3ee4fg/org.x:0
Is there any way that I can just take the value '/tmp/launch-3ee4fg/' from the output of $DISPLAY and exclude out the filename to the end of the command. I tried using the read command and the IFS variable..apparently IFS does not recognise / I guess.
the samba seems not working ever since i fresh install from system. When i want to share a folder, error message appears :

I just performed a fresh install of 11.04 Server. The installation went smoothly and as expected. As soon as I leave the BIOS and Ubuntu boots, however, I lose my display (my monitor says "Cannot display this video mode"). I am able to ssh into the machine just fine, so I know it is booting up fine; I just don't have a local console.
Other threads related to this topic suggest adding something like "vga=771" to the boot options in grub/menu.lst, but I don't see that file anywhere in my 11.04 server install. Where can I configure display settings now?

I'm running 10.04 x86 server with a really simple installation on a single 250GB boot disk. I then have a RAID5 array as /dev/md0 (set up using mdadm with x4 2TB disks). All is working well. My mdadm.conf file looks like this

if I was to lose the boot disk and need to remount the RAID array on a fresh installation, what steps do I need to go through. My assumption is that the superblocks on the RAID disks will be used and I don't need to keep any additional information - is this right?

how to access a FTP server with php. I've written a script from a tutorial but I'm getting errors with the ftp_get function.
PHP Code:
[code].....
Warning: ftp_get() [function.ftp-get]: Error opening /var/www/download.txt/ in /var/www/gwr/connect.php on line 11
I'm having trouble with the ftp_get function and I believe the problem is with the local server path. In this case var/www/download.txt I've also used a folder in that directory called download in the place of the .txt file and it gives the same errors. Is var/www/ the correct path to tell php where to download the files to? I've experimented with the files permission and nothing has worked. I'm running a standard ubuntu desktop install, Karmic Koala.
I have a startup script which calls other scripts which need to run some utilities I have. I've tried changing the executable path by adding it to .bashrc:
Code:

echo "export PATH" | tee -a /root/.bashrc /home/$user/.bashrc
But this only works for finding executables once the boot process is over. The startup scripts don't see this path.

I'm writing a script to rsync some directories to external hdd for backup.
My external hdd gets automatically mounted to /media/backup1
My script then backs up predefined directories to /media/backup1.
I have added this script to cron to run once every day.
The problem is that in the case where the drive is not plugged in and the script runs, it backs up to my local hard drive, and since it is more than 70% full, it fills it up by duplicating that 70% onto itself.
I have taken the script further, to test whether /media/backup1 is mounted. If it is, the backup will run. If it is not, it will bail out.
I'm using the mountpoint program to test for mounts.
My script so far:
Code:
#!/bin/bash
if [[ `mountpoint /media/backup1` ]]; then
echo "filesystem mounted"
# The backup function. Commented out for testing.
