Ubuntu :: 3TB HD (with Data) Expanding To 3x3TB RAID (without Losing Data)?
Jul 27, 2011
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.
I have a software RAID array using mdraid that consists of two 1.5TB drives that I use for storage, the array is mounted at /Storage. I am running out of space in the array so I ordered two more 1.5TB drives to create a 4 drive RAID 1+0 array which will be 3TB big. My question is how do I create the new array and not lose any data?
The drives and partitions are sdc1, sdd1, and soon to be sde1, sdf1. I currently have 4 RAID arrays (md0,md1,md2,md3). I think I can create the RAID 1+0 array with the two new drives, copy the data from my current array to the new one, remove the old array, then add the two original drives to the new array. But I wanted to ask on here first to make sure my data doesn't go poof.
This forum might not be the best place for this question, but some people here are pretty knowledgeable and may have more insight than I do about this. Anyways, I'm thinking about expanding an NTFS (Windows 7) partition on my desktop computer into unallocated space. I know that there is a risk when shrinking a NTFS partition due to fragmentation but are there any risks of data loss from expanding a NTFS partition? My common sense tells me there isn't a risk but I want to be 100% sure I won't lose any files.
I am completely ubuntu right now, and I need to create a partition for XP without losing all the work I have on ubuntu. How can I shrink ubuntu's partition to make a 15 gb partition for XP without losing data?According to Gparted:
I have Ubuntu 10.10 installed on my computer (no other OS) and it wont boot up. I don't want to lose the files in my documents. I tried accessing them using a live CD and then copying them from the harddrive (home folder then 'richard' then documents then tried to open the folder but I dont have permission to and there seems to be no way of changing this.
The files are definitely on my harddrive but I dont seem to have a way of accessing them!
Is there anyway of either accessing them and copying them to a usb etc or repairing my installation of ubuntu without erasing the files in my documents? Opening in recovery mode etc wont work.
I am facing a severe problem on many Desktop PC's, whenever an employee is working in Gnome-Open-Office.org document (i.e. Wordprocessor, SpreadSheet, or any other Gnome-office application) and due to power outage after restarting, the previously open document either does not open or it shows a recovery dialogue after clicking on recovery button or clicking on cancel in either case document contain nothing (empty). The file size of the document is either 0kb or within few Kbs range.
Any one have any idea about it ? what to do ?? or any other alternative which is already tested in such environment (i.e. electricity failure )? or any options to be turned on/changed?
I would like to move a samba fileserver from ClearOS5 to Ubuntu. It has raid1 (software) and I would like to save one partition from it, md3. The other partitions could be used for Ubuntu. How would I go about this so that I don't erase data from md3 and is it even possible?
I need to reinstall OpenSUSE 11.4 with KDE Desktop on my HP Pavilion Desktop and I was wondering if it is possible to do so without losing my data, and no backups? I can't back up my data for reasons I'm not going to go into so I need to know if I'll lose my files...there isn't anything truly important...just stuff that'd be mildly irritating to lose...
I would like to resize my /home ( /dev/sdb6 ) partition - without losing data - to make room to create a swap partition (at the moment, I don't have any swap. Is it dangerous ?) IIRC, it was possible to change partition sizes from the install disk in repair mode (?) But I cannot find that repair mode on the 11.3 install disk. Has it been removed or is it somewhere deeper in the install or update process ?
to start: I am a 100% linux virgin. I have yet to boot once. I have a 1TB external HD bought today (), which I formatted to 32GB Fat32 and the rest NTFS. (The 32GB partition is the second in order) I tried installing 11.4 with the full release DVD, and managed to get through the 'partition' part of the setup without raging about losing valuable internal HD data. I changed / to the 32GB partition, and figured a native format was safer: formatted it in setup as Ext4, and installed after ignoring the under 128GB warning (the machine is only a few months old).
The installation seemed to go well. The loadup was unsuccessful. There were plenty of "fails". I was given a command screen with "Login:" and after, "Password:". It seemed to take the Login, however the correct password echoed back a "Login module failed" or something similar. Interestingly, an incorrect password yielded a "Incorrect Login". What I may need to do (?):
1. I did not specify a /home or swap during install 2. ? 3. ? etc
I have a 300 external usb drive which I have got when using windows and so is using a fat32 filesystem. I have since moved to linux only and am mounting the drive as vfat however I think I may as well convert it to ext4 if possible for (amongst others) performance and security reasons. The problem is I don't have a separate drive which would hold the 250gb of data temporarily whilst I changed the filesystem of the drive so I am hoping there is a way to format as ext4 whilst retaining the files?I know partition magic on windows allowed you to change between filesystems whilst keeping the data but does anything similar (and free! ) exist for linux?
Can any data be lost on ext4 with full journalling mode when electricity crashes? I know it's possible on filesystems like JFS and XFS because they don't journal data (only metadata). When ext4 in "journal" mode journalles both - data and metadata. Does it give 100% guarantee that no data can ever be lost in case of problems with electricity?
I updated to Thunderbird 3 by following instructions from http:[url]....Everything updated nicely, but in menu I don't have Thunderbird anymore - there is Shredder instead.Also Firefox was automatically updated - with change of name to Shiretoko with different icon. Wanted to make sure I added safe repositories, and why these changes?
ps. i checked some websites and seems like it is installing alpha/beta versions. so since it is not working now - how do i revert to previous versions without losing data, and how do i install thunderbird 3.0 then.
I am running ubuntu 11.04 I'd like to encrypt my home folder. - how can it be done, without creating new user/starting from scratch. -I'd like to keep all the files and desktop settings - the only change should be that the folder is encrypted now.
I 've some problems with my current version 11 that probably has been fixed in the last version (14). I've updated other non-critical systems through the yum services but from 13 to 14. I've a productive workstation working on ver.11. Is there any possibility to update through yum or other methods through without risks of losses data information?... It's really complicated to backing up Mysql databases, web services and other hundreds things installed. I know, it's convenient carry out a backup but is it a higher risk to dump from 11 to 14 trying to keeping the information inside?
In my hard disk I have win xp, opensuse 11.1 and ubuntu 10.4. I'd like to replace 11.1 version of opensuse with the last one 11.3 without losing data and setting in other partitions. this is my hd:
I think (but I'm not totally sure) I installed opensuse in dev/sda6 and dev/sda7...what is the right thing to do?? should I have to delete /dev/sda5 /dev/sda6 and /dev/sda7 partitions and then install opensuse 11.3 in the new free space??
I have Windows 7 working on my laptop. I have 20GB space unpartitioned. I want to install a flavor of Linux like Fedora or Ubuntu in that space, but I have heard that keeping a dual OS configuration sometimes results in losing data stored on the hard disk. I've also heard that it may sometimes cause unrecoverable problem because when Linux is loaded on hard disk it will take over the boot loader from Windows.
Is this correct? Moreover, I have 6 partitions in Windows, but if I use a Live CD for Ubuntu or Fedora to boot, then it is not showing some partitions -- sometimes it shows only 4 or 5 partitions. What might be the problem, and how to resolve it without formatting the whole hard disk and repartitioning it?
I've initialize a virtual disk and deleted the partition table didn't notice that i've done that to the wrong one, data still on the physical hard disks but....how I'll get my data back safe without losing it?
Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u) Well yesterday this disk just would not mount. Read through related posts but nothing seemed to work. Even tried it on a Windows machine.
Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...
Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.
How can i repair the partitions and MBR without losing all my data?
So I've pulled two hard drives out of my busted windows xp system (dead mb) and I'm trying to get some data off of them. The drives are in raid 0, so my friend told me that I might be able to do something if I use linux. Some late night searching on the internet directed me to a few resources, one of which was this forum. I've tried 2 methods, neither of which have worked.
ubuntu@ubuntu:~$ sudo mdadm --detail /dev/sdb mdadm: /dev/sdb does not appear to be an md device
ubuntu@ubuntu:~$ sudo dmraid -s /dev/sdb: "sil" and "hpt45x" formats discovered (using hpt45x)! ERROR: sil: wrong # of devices in RAID set "sil_agafdhcebccj" [1/2] on /dev/sda ERROR: removing inconsistent RAID set "sil_agafdhcebccj"
I've got some files for work that I'd really like to get off there. I've played with unix a bit in college and I've ran ubuntu before, but usually using the GUI, so a lot of this stuff is over my head. But from what I gather, my system thinks that one of the drives isn't a raid drive?
my question is quite simple and at the same time should even sound weird for people that is used to use raids... but here we go! I have got 2 hard disks that do match in space. I'd like to use mdadm to create a raid 1, the mirror one. Since I don't want to format / erase / delete what's in my primary hard disk (/dev/sda, 3 partitions), how can I replicate its content into /dev/sdb and mirror it with the raid tool? Does something like this work?
