I've set up a RAID-1 array /dev/md0 consisting of two partitions /dev/sda5 and /dev/sdb5.The partition /dev/sda5 was formatted "ext2" before mirroring, but now when I "mount -v /dev/md0 /mnt", it says "/dev/md0 on /mnt type ext3 (rw)".Why is the type changed from "ext2" to "ext3" ?
View 2 RepliesI have a question, i accidentally formatted an lvm volume as ext2 after creating it. Then of course, we copied a ton of data to it before I realized it was ext2. (I guess ext2 was the default when using mkfs without a -t) Anyway - can I just use tune2fs -j on the LVM just like I would a /dev/sdx device?

Anyway, I have found that my bios does not recognize the hard drive when formatted to ext2! I have taken the drive and formatted it back to ntfs, and my bios recognizes it, and then back again to ext2, and nope, it's not there, thus I am still booting puppy from the cd...sigh...
Is my bios so out of date that I'm just out of luck? Is there anyway to check this?
i am not able to mount a pen drive (which is formatted in ext2 format) with directory permission drwxrwxrwx and file permission as -rw-rw-rw.

View 9 Replies View RelatedI'm doing a fresh install of xubuntu 11.04 x86 32bit via the Alternative CD. My computer has two 2TB drives and I want to mirror the partitions for redundancy For the Linux partitions (ie root and swap) I'll be creating raid partitions on each drive and using software RAID 1 to create md partitions of type ext4 and swap.
For the GPT's bios boot partition, am I also meant to use software raid ? Ie create a raid partition on each drive and use software RAID 1 to create a md partition of type bios boot ? Or am I meant to not use raid partitions and just create a bios boot partition directly on each drive ? In this case, will xubuntu's install process and grub tools ensure that both partitions contain the relevant grub files or do I have to explicetly do somthing to ensure that ?
i TOTALLY ****ed up my windows bootmgr, and, in some way, the linux partition too. I'd like to format the windows partition, but as all my info stays intact I'd like to conserve it that way. The only way I can think of, is to make a new ext2 partition on the same HDD y have windows ( I only have one HDD, so... ) and save the information there . Wich is the correct way to do so, without losing all my software and/or information??
Other details:
* Rright now, i don't have ubuntu installed on my pc ( I'm using a live cd ).
* I'm using ( or was ) win 7.
* The only partitions on my HDD is an ntfs ( 60 GB ) and an unallocated ( 240 GB )
I had to install a new disk drive in my PC a week ago because the old drive died. The new drive is a 160 gig drive. First I installed Win XP with S/P 3 and everything was fine. Then I installed Ubuntu 8.04 and the troubles began. Ubuntu resized the Windows partition down to 8.81 gig and used the other 137.44 gig for Ubuntu. When I booted into Windows I started getting nasty little messages about "not enough disk space". SOOoooo....... I booted using the Ubuntu install CD and ran "sudo gparted" in a terminal window. I tried to resize the ext2 partition but got an unknown error.
Then I ran fixmbr in Windows to get rid of grub. Then I tried running gparted again to delete the ext2 partition. Got an error that said "can't delete the partition because it's mounted". So I tried to unmount the partition but got a message that the command "unmount" could not be found. After that I installed Partition Magic in Windows and tried that. It sees the ext2 partition but says it's unsupported when I try to delete or resize it.
I ran fdisk but it doesn't see the Linux partitions either, so I can't delete them in that program. I finally tried to format the disk but now I have a 9 gig drive with nothing on it. How do I get those Linux partitions off the drive so I will have a 160 gig drive that I can start over with? I've spent 6 days this week reinstalling XP and all of my programs, and now everything is gone because Ubuntu decided to be a disk hog.
I was installing windows vista on my computer, so I backed up everything to a external drive which was formatted with ext2. I then proceeded to install windows vista. When I got to the partition section I tried installing windows vista to my raid 0. When it didn't work I decided that I would delete all my existing partitions and create a new one. Well in my haste I accidentally deleted my ext2 partition from my backup drive that was still connected. As soon as I realized what I had done I shutdown the windows install and disconnected my external drive. This is the current state of my drive from parted:
Model: WD 15EADS External (scsi)
Disk /dev/sdb: 1500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
I know that the drive only had one partition before and that it took up the entire disk and it was ext2 (maybe ext3).
This might be a longshot but i used to use the 4 bay NAS here Which formated the HDD JBOD array to EXT2 , Anyway i want to move to an 8 bay DAS now but i cant find an application to convert the partitions .
Partition magic says the partitions are unformatted and the partition id is set to linux raid auto . Is there any way to convert this partition to vanilla EXT2 so i can use partition magic on it ? Its a 4TB array so copying isnt possible.
I have a usb flash drive and according to sources I found out after the fact that I should have used ext2 instead of ext4 due to the extra write operations.
Is it possible to convert the ext4 root partition to ext2 or do I need to backup, reformat, and restore?
Since Mac OS X, runs a BSD Linux at the core I think that this is the correct place to ask about this, but I need cfdisk to make some ext2 and swap partitions on some Compact Flash and old HDs without needing to download any LiveCD. There is any cfdisk that I can use on my Mac?

View 1 Replies View RelatedI need to mount my ext2 partition with write permissions for an average user. Right now, I can only write to the volume using sudo or the root account.
/etc/fstab:

can't add the options uid=500,gid=500 to the ext2 volume because it says "bad option" I have 1 question. If you have a volume listed in /etc/fstab, and you try to mount it with different options than the ones listed in fstab, will it mount with the new options, or the fstab options?(e.x. if I try to mount /dev/sda6 with: mount-o auto,user,exec,rw,async. Will it mount with async or sync?)

I work with a Debian Squeeze on my laptop and I have a 160GB external hard disk. My hard disk was formatted FAT32, but I decided to format it using ext2. I formatted it using fdisk from command line and everything went well. Unfortunately, when I mount my hard drive(which is auto-mounted from Debian) it has got root both as owner and group. Then I can't write to it because I have no permission to do that. Is there a setting to create an ext2 partition which has as owner the logged system user in order to have right permission every time.

I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.
I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition.

View 3 Replies View RelatedI had 3 partitions on my hard dive, Windows 7, Ubuntu, and just junk on the other. I installed Ubuntu in a way where it went to the GRUB filesystem? first, where it ask me to start in linux kernel 2.38.6 (can't really remember the kernel exact name) which was ubuntu, some other options, recovery mode, and at the very bottom was the one to go to Windows 7. I was in Windows and I wanted to get rid of my junk partition but I formatted the Ubuntu partition by mistake.
Now when it boots up it saying:

My colleague needed a backup for some of his loose media, so I assured him I could back it up on our Lab's Lacie 2TB external. His windows partition was incredibly sluggish, so he booted into ubuntu 11.04 and we partitioned and formatted an NTFS volume for him to transfer his stuff to. The format went fine, space was available, and I left him to transfer all of his stuff from his dell studio1555. He finished and reformatted his computer completely.
The NTFS is not recognizable by any of the OS now. Ubuntu sees it as a single partition without any data, whereas before the transfer, the partition map was clearly visible. Windows does not recognize the drive at all. OS X does recognize the partition, but it shows up as an apple_scratch volume, which is quite a bit frightening, considering a scratch volume is essentially blank. To elaborate, all of the files were in his windows partition, and were transferred within a relatively fresh install of ubuntu (not much had been done on it). The partition was made in diskutility in ubuntu (the GUI), but the rest of the drive was HFS+ formatted.
I was using windows 7 and I decided to install BackTrack 4 as an operation system so that I can have 2 operation system on my machine, during the installation, I accidentally formatted the windows 7 and right now, I am using only the BackTrack 4, now, I want to re-install back the windows 7 as an operation system but whenever I inserted my CD, it display this words under the Default: >/ubnkern initrd=/ubninit
It needed a command from me in other to proceed but am new in Ubuntu and I dont know what I should type or the command I should used in other to finish installing the windows 7.
By mistake I formatted an ext3 partition on my external hard-drive. Now it has turned into a vfat filesystem. Is their any chance of recovering the lost data?
View 4 Replies View RelatedI just installed suse 11.3 on formatted partitions (5GB swap, 30GB / and 500GB /home). Just after the installation, My computer showed 25.2GB of /home to be used. When I do:
Code:
dyn-0a2a1f40:/ # df -h .....
That seem to be roughly correct because since yesterday I've been running a program that constantly writes logs and other data files and plots, which might have accumulated a few GB's. It is also collaborated by the output of
Code:
dyn-0a2a1f40:/ # du -sk /home
10548452 /home
I'm not hard-up on space right now but storage has been dear until the recent past. Also out of curiosity, the size of the /home partition is shown as 493 instead of the 500GB allocated while the swap also lists only 4GB instead of 5GB. Below is the output for fdisk -l in case anyone needs it:

I have Linux 2.6.34-12-desktop x86_64 and KDE 4.4.5 (which I had previously used in 11.2 without any problems) and 4.0GB RAM.
I was installing 10.10 x64 today. I wanted to manually partition the disks, since I have a /home partition from a 9.10 installation which I want to keep.Unfortunately, I selected to convert the ext3 /home partition to ext4 and didn't realise it was formatting the partition until it had just begun. In desperation, I pulled the power plug, but now I can't access the partition (using the LiveCD) - comes with an input/output error.What are some strategies to recover the data on the partly formatted partition? I don't think much, if any, was actually formatted.
