I have two identical 160GB hard drives and I'm planning on setting up a server, probably ubuntu, for Glassfish, mysql and subversion. ince I'm using those applications I'm assuming I should have a large var partition for mysql, and /opt for glassfish and I'm not sure about subversion. Is there a good partition layout you can suggest for me for my 2 drives?

View 2 Replies View RelatedI currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.

View 1 Replies View RelatedI'm at a stage where I can start using Linux for all the tasks that I currently do on Windows and am keen to make a full switch to Linux. I have played with Linux a few times over the years, installing different distros etc, but I've never set up the hard drive partitions manually. I only want to make the switch once I have a good grasp of how to configure the hard drives as I have a lot of precious data.
A question I have is that normally I would set up a small partition for the OS, then have another large partition purely for data. What would be the best way to recreate this kind of set up with a Linux file system (i.e. keeping OS and user data separate)? Where would be the best place to store a mass of data that wouldn't necessarily be associated with one particular user? I've seen about having a separate partition for users home directories, but I don't really want the data associated with one user so it would seem more logical to store it somewhere more general.
My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
I am trying to move a whole bunch of files from one partition on one hard drive to the same partition on another hard drive. Can I mount the same partition (same name, different drives, i.e. /data on /dev/hda1 and /data on /dev/hdb1)and copy those files? Shutdown the server, take out /dev/hda1 and boot up with the new drive and it's /data contents.

These hard drives were unplugged during the installation. After I was done installing I shut it down and plugged them in. They are NTFS format. Will they automatically mount? If so where are they? If they do not automatically mount how can I mount them?
View 1 Replies View RelatedI have a linux box that I'm using as a ADSL router (slack 12.1).Until recently I had two hard drives in it, one for linux, and one for storing movies, music, etc.So, I have just bought another 1,5 TB disk. My plan was to add it to the same mount location: /opt/abram to expand my storage disk, only to come to conclusion that this can't be done. OK, it actually makes sense, if I thought about it I would realise it before. Anyway, what else can I do? Is there a way to add new drive to existing one in a way that would result in one 2,5 TB drive?
I tried it with mdadm, but as it turns out, it's impossible to crate RAID 0 without loosing all the data on sda1 disc.Also, it would be very cool if I could find a solution that would enable me to one day add a new drive to further expend my storage.I'm aware that I could mount my new disk to, let's say /opt/abram/Divx, or /opt/abram/mp3, but that's not the solution I'm looking for.
Much of the documentation about the subject refers to, by today's standards, fairly small hard drives so I'd really appreciate your views on the subject of slicing up large hard disks and any links on how to partition a 160 giga drive or a 500 giga drive?
1. How to partition a new 500 giga hard driver for a server? I don't know what to do with so much space; maybe I should use it for my desktop system and use, for example, two 160 giga drives for the server because I'd like to back it up using RAID.
2. The server has 4 GB RAM. Is such an enormous swap partition, double the RAM size proposed by the installer, necessary?
I want to configure Name Server i.e., DNS to my red hat linux box in a production enviromnt.The ram is 2 GB and Hard Disk size is 200 GB. How much space should I give /var, /usr, /boot, /root and home partition. May be I am wrong in partition point of view while installing fresh red hat but to install for home purpose and server end is different. So kindly guide me the hard disk partition size to ready it for name server.

View 3 Replies View RelatedAny basic description of how linux assigns drive letters? I understand that a drive letter assignment is not static. If I add a drive between /dev/sda and /dev/sdb, my /dev/sdb will become /dev/sdc and the new drive will become /dev/sdb. I have a hot swap tray and have come into some unexpected behavior. I removed /dev/sde from the hot swap tray and then loaded another drive into this same tray. When I mounted the new drive with options in fstab, it wouldn't mount because the new drive was /dev/sdf, not /dev/sde. Apparently, linux is looking at the id of the drive in addition to it's place in the BIOS chain.
My fstab entry is:
/dev/sde /backups auto noauto,rw,noexec,async,user 0 0
I was avoiding using UUIDs in the fstab so that new HDDs would not have to be "registered" in the fstab prior to use. Is there a way to tell linux (or fstab) whatever drive is plugged into SATA channel X mount to /mountpoint?
By using ISO2USB for CentOS/RedHat I installed with out having to burn A single cd or dvd. Super easy and free from source forge. Link[URL]... Unplug the USB drive and take it to the machine to be installed.Reboot the machine and choose USB boot option in the BIOS boot menu. Choose Hard drive installation method and select /dev/sdb1 as partition that holds ISO images. Use sda drive for installation and choose to review the partitioning layout. In advanced bootloader options, change drive order to "sda sdb". Proceed with the installation.
So easy it should be a tool in every admins box. I hope I saved you some time and headaches.
I installed Redhat Enterprise 3 on one of my servers. In my haste I didn't properly partition both Hard Drives and only properly partitioned one of them. Thus now I have
/dev/sdb1 478711768 137858256 316536328 31% /
/dev/sda1 101089 15346 80524 17% /boot
Where /dev/sda1 is actually a 80 GB hard drive. Is there anyway I can safely and easily repartition the unpartitioned space without causing a huge mess? I have a very important Oracle database on /dev/sdb1 and thus I want to be able to back it up on the second disk. I can create a partition on that drive?
We have a server at a friends house with a hard disk that's filling up so he picked up another hard drive.

It's running centos 5 with samba ... with EXT3.. and I don't believe it's using LVM.
I seem to have a complex issue on my hands that i can't figure out. first, i wasn't able to get access to my LVM'd hard drives via SSH without half of the content being missing or locked out (read-only or unable to open at all). the problem then went up to being unable to boot up - all i got was a long slew of [100.1234] ata1.00: error messages (they eventually DO stop once they get to around 998.234234 or whatever, and then i can log in and it seems to be "stable").
Part way through this rebooting ordeal i realized / decided to make power-on-self-test stop and wait if it finds errors (via bios) - that showed me that my 750G SATA drive is "bad" and my two (older) 120G & 250G IDE drives are "ok". i then unplugged the SATA drive, rebooted, and didn't see those error messages. however, my LVM was still obviously not coming together (since LVM was made up of the 120G, 250G, and 750G drives)
So, now it seems:
a) I can't boot smoothly with all drives in place
b) I can't do anything with lvm if i remove the 750G sata
c) With all drives hooked up, i can wait 10mins for the errors to go away, but STILL can't do anything with lvm
d) I need to recover the lvm stuff so that i can nicely migrate ALL those files (1.1TB of it) onto a new 1.5TB drive and do away with lvm
This is all running ubuntu 7.10 server edition (32-bit version on a 64-bit computer). i DID post a question on the ubuntu forum as well but so far got no replies at all.
Here's a few pics of the booting process, with one or two "fail" lines showing.
So I built a new system few months to act as a development/"mess around with" server with an Asus Mobo and a Q6600 processor and 8 gigs of ram. Along with file, web and app hosting, I also do some virtualization on it... or atleast I had hoped to.
Ever since the first install, I've been randomly getting crashes and lockups. Sometimes it would just dump an error to the screen but stay alive, and sometimes it would dump an error and then lock up fully. The error mentions something about "kernel not tainted" etc. I will post the detailed error once it comes up again, as I have just formatted it again.
Other problems include downloaded files becoming corrupt. Files downloaded through any means (wget, torrents, ssh, ftp etc.) seem to randomly get corrupted (ie: the hashes are wrong).
I currently have one WD 150GB raptor as my primary OS partition, and 3 WD 1TB greens as my storage in an mdadm raid 5 array. At first, I had thought it was the raid array or it's drives causing issues. After painfully transfering the data off of it, I took the drives out and tried to run ubuntu with just the OS drive for a while. This still had the same issues. I then put in only one of the 1TB greens and had the same issue...
I downloaded WD's hardware diagnostic tool and ran full scans on all the drives. They all check out fine.
I left memtest running overnight and it had no errors either.
Most recently, ubuntu would not even install. It would get stuck at the stage of partitioning, and the keyboard lights would flash. After much googling, I tried popping in "noapic nolapic" to the end of the grub string, and it managed to install.
Now, I'm in a fresh system and just wgetted vmware server. However, it wont untar, I just realized the MD5 hash doesn't match!
So definately not the memory or the hds... I'm assuming it has to do with the APIC? From what I found on google, it seems as though this is only needed for the install.
Do I really need this to be on the boot string too? From what I understand, APIC allows processes to be divided out to the least loaded CPU. Having a quad core, I'd rather leave this on since it seems somewhat beneficial... I have yet to try putting this into the grub yet since I'm offsite and need
As a side note, this latest install is using just the WD Raptor as an OS drive.
And I'll post up the dumped errors if I get them again. There were none dumped out when the vmware download corrupted. The message format is very similar to the one here: [url
However, sometimes it mentions ext3 (or one of the other filesystem types I had tried with thinking it was a problem with ext3) Again, the error message is not the EXACT same, however the format is very similar...
