I've been thinking about this pretty heavily and am thinking about using LVM to store my media collection. The USB hard drives (3x1TB) are plugged into my Mythbuntu server and are never unplugged. The only issue I forsee is that the USB drives spin down when not in use. Will this cause any issues with LVM? I have about 750GB of data on one of the drives and, obviously, want to keep this data. I think the existing data makes it not possible to use a LVM mirror (correct me if I'm wrong).
I was thinking that I could create a 2 disk LVM with the unused data. Then, copy the existing data to the logical volume. Lastly, add the third disk into the volume group. I know doing this does not add any redundancy. Would it be wise to add a RAID1 or RAID5 on top of the volume group? Does using USB drives make this unstable?
I have a system that has the following partitions:
Now SDC is a new drive I added. I would like to pool that new drive with the raided drives to give myself more space on my existing system (and structure). Is this possible since my raid already has data on it?
In the process of preupgrading to FC12. Towards the end of the process I get a warning that my /boot partition isn't big enough (12 recommends minimum of 300Mb).
Is there a tool I can use to resize my existing partitions WITHOUT data loss? I've been using gparted up to now for sorting partition stuff, does that maintain data when resizing (assuming I run from a boot CD or USB rather than a running system)?
If I have a partition like /dev/hd1 that is unencrypted and want it to be encrypted, but want to keep everything currently in that partition, how can I do that?
I have a BIG extended partition. It's at about 750Gb. Aside from that, I have 2 unallocated spaces, one at 240Gb and one at 5Gb. I want to make one of my storage drives bigger, and so that I can take advantage of all the space I have. (Those 250Gb have been unused for ages. I want to use them for my growing libraries.) So I wonder: would it be safe to put these smaller "chunks" into the extended partition, and still have a working systen? I don't want to mess it all up.
Also, can I safely resize a partition, like adding the extra space, without touching the existing data? I'm not exactly sure how the resize/move function in GParted works. Will it wipe and extend or only extend it by adding it? It would be nice to have these questions answered. Also, if it's to any help, this is my partition table as of now:
[Code]....
As for the first entries, they're unallocated. They're the primary drives, but they don't exist. I'm actually considering to move my partitions out of the extended one, because I only have 3 partitions that I use and will ever use. But if the extended partition is not a problem, I will just keep it this way.
I'd imagine that I first extend the extended partition to consume the unallocated space, and then I move it all to the end of the partition, and then resize sda7 to consume it, and get a 750Gb partition. Can this be done without loss of data?
I have an existing OpenSuse 11.3 (64 bit) box serving a couple of websites. I would like to enable Xen. Question - If I install Xen through Yast, will my existing configurations be reset and will I loose my existing data? Does Xen have to be installed on a clean system?
I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.
It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such
Found Disk: hda Found Disk: sdb
so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on
I have an existing unix user that some how didnt make it into the copy over to our LDAP server. How do I add an existing unix user to an existing LDAP directory? Will ldapadd work? I was under the impression ldapadd required an ldif file to work properly.
I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.
Right now I have a 320GB system drive and 3TB data drive. I want to add two more 3TB drives and do a software RAID5 3x3TB. Is that possible without losing the data that is already on the data drive?Just want to make sure before I bought the 2 two drives. Not looking for instructions on how to do it,but if you want to include some that would be great too Just making sure it will work.
We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?
A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x7ca36fee
[code]....
Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:
umount /data/ umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a mount: /dev/mapper/gegevens-Data already mounted or /data busy
I'm trying to connect to the VPN of my employer; after fix various minor issues I reach this point in which the DNS entries and the default gateway of the VPN are overwritten with the values of the eth0 device that appears by default. Therefore the vpn is not useful.
I have an application where I am sending data via serial port from PC1 (Java App) and reading that data in PC2 (C++ App). The problem that I am facing is that my PC2 (C++ App) is not able to read complete data sent by PC1 i.e. from my PC1 I am sending 190 bytes but PC2 is able to read close to 140 bytes though I am trying to read in a loop.Below is code snippet of my C++ AppOpen the connection to serial port
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.
I want to install Ubuntu on a PC and have just started reading the Ubuntu pocket guide.All the install options seem to require a pre-existing OS ("dual mount" and so on).But I want to install Ubuntu on a new PC and especially do not wish to pay the Microsoft Windows license fee. I want Ubuntu to be the only OS on the box.
when registering my account online (I use Ubuntu 10.4), I for some reason did not get the "Confirm Computer Access" screen (no, I did not overlook it!).In the Ubuntu One client, my machine is listed as <local computer>, and I cannot figure out how to add this computer to my existing account now.
Can you repair an existing install with a distro CD, IE Run the install with a switch to just repair rather than "install".I have messed up a Ubuntu 10.4 Netbook install by playing with the Mount Utility trying to mount a SD card, and now my netbook will not boot.
I've downloaded the ubunto latest install and everything went well but I didn't make enough space to share with my windows xp OS... Ubunto has become an OS option pre boot mode but needs more room to execute fully .everything on XP op is still fine
I sudo apt-get uninstalled a bunch of stuff I shouldn't have. Now my Ubuntu Partition doesn't boot up correctly, something about the graphic system, video system, etc. all being unconfigured. (I'll get the exact error later.) All I can use is the command line.can I install Ubuntu over my old Ubuntu partition without messing up rebooting/GRUB and all that?
I am running ubuntu 10.10 on a drive with 3 partitions. 1 windows and 2 ubuntu partitions.
The ubuntu that I am running right now is on a partition that is too small. I need to either expand it to include the other ubuntu partition or reinstall 10.10 and copy my existing partition to it. Can this be down?
I have this version working the way I like it and have tried 11.04 and am holding of for now. Still the fact remains that my working copy is on a partition that is really too small I only have 2 gig free space on a drive that is a 500gig.
I have question about embedding existing mysql data to FTP. Let me tell you how the system works. Apache gets the user name and passwords records to the MYSQL and creates a folder per user in server. However users can not access their created folder using FTP client software. So how am I gonna merge the existing user/password data in MYSQL ---> to the FTP user/password. Vsftpd and proftpd installed already, so in whichever you feel more knowledgeable, I can go with that.
I am trying to generic way to convert the string datatype to other primitive data type. To achieve, i used Template . But i getting error and couldn't resolve the issue and error reported is also clueless.
About 7 years ago I setup a Redhat system with 8 serial terminals and 8 serial printers, this is still running but I need to get another system running so the original can be taken down for maintenance. The printers are ancient Newbury data dot matrix wide carriage with 7 data bits receive 8 data bits transmit Xon/Xoff flow control. Now I remember setting the transmit and receive data bits as above but after 7 years can't remember where.
I have a laptop running Ubuntu 8.04 LTS and I need to upgrade to the new Ubuntu, I order to get complete use of my hardware. Usually when I install a new version of Ubuntu, I have the opportunity to use my old partitioning, but now I can only use the entire disk or create a new partition table.
The laptop has other partitions that is a data and a Windows partition as I want to preserve.
How can I install the new Ubuntu on the old Ubuntu partition and preserve the data on other partitions?
Is there a way to get the 10.04 Live CD to recognize my existing 9.10 installation and perform an upgrade without deleting all my files? I have been blocked out of Ubuntu 9.10 since December when I installed Windows 7 and it overwrote GRUB.
