I've done a search thru the forums on a recent headache but couldn't find anything. now we all know that windows installations knackers the grub boot-up, and it becomes modus-operandi to repair the boot loader, with a live distro. however, in my current dual boot system (vista.sp2/fedora12), i've done a clean install of windows7 over the current windows ntfs partition. as standard, the boot menu would vanish. but when i put in the live-linux cd, gparted now shows the fedora partition (sda6) as LVM2. i'm somewhat of a neophyte with linux, but fedora12, suse11.2 and ubuntu don't seem to yet support this file system.
since i don't have critical data on the fedora partition yet, i usually wouldn't mind reformating this part', but the wireless chipset on my laptop cost a fortune on cups of coffee and beer to install, and in addition i used the fedora12 FEL spin and want to keep the installation intact. is there anyway to make the LVM2 indentifier back to ext3 or 4 and repair grub form there (without loosing the current partition kernal etc.)?
I have a external HDD with eSATA and USB connectors available. I want to use this HDD to store my backups. The HDD should be encrypted (my main system is as well).
So here is what I did so far: 1) I used the following code to create the encrypted LUKS partition with EXT3 Filesystem: Code: cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/sdb1 cryptsetup luksOpen /dev/sdb1 luks mkfs.ext3 /dev/mapper/luks The system always hang when I executed the "mkfs.ext3..." command, so I switched the HDD from eSATA to USB and then it worked fine.
2) When I switched on the ext. HDD the first time, the drive was recognized automatically and Nautilus asked for the password. I typed it in as checked the checkbox to remember the password in the future. For the backup I use a nice script that I found in another forum, where I can define a mountpoint and then the script will check for previous backups and only make a incremental backup based of the latest version. The script also mounts the drive automatically. In order to always have the same mountpoint, I want to make an entry in the /etc/fstab using the UUID of the ext. HDD.
Whatever I tried, it doesn't work. What am I doing wrong? Here is my current /etc/fstab Code: # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # / was on /dev/mapper/ubuntu-root during installation UUID=2ea47421-73ce-4c66-9606-8a1db81ae640 / ext3 relatime,errors=remount-ro 0 1 # /boot was on /dev/sda1 during installation UUID=dbdeb793-1d4e-43ea-8986-7b37fdbc9674 /boot ext3 relatime 0 2 # /home was on /dev/mapper/ubuntu-home during installation UUID=42702091-83e6-43eb-aad1-108f43eedf9d /home ext3 relatime 0 2 # swap was on /dev/mapper/ubuntu-swap during installation UUID=e225bcf9-908b-4226-a963-6b02ee658df1 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 # Eintrag wegen iPhone none /proc/bus/usb usbfs devgid=125,devmode=666,nodev,nosuid,noexec 0 0 # external HDD UUID=913977f7-8fa6-416f-af79-b5f913b68f53 /media/backup-hdd ext3 noauto,users 0 0 I made the "none /proc/bus/usb..." entry because it was recommended to ensure correct behaviour of the iPhone. Not sure if I need it though.
I created the mountpoint with this command: Code: sudo mkdir /media/backup-hdd Now it seems the mountpoints owner is not root - strange right? Code: 2 4 drwxr-xr-x 3 michael michael 4096 2010-01-15 02:45 backup-hdd How should I mount this drive correctly? It will be automounted as every USB device, but that should not be the case. I want the script to mount and unmount the drive.
I am running Suse 11.0 and the system had stopped working. I booted from the disk and chose repair system. Now I can get to the Give root password for login and it accepts the password, but I get the line (repair filesystem) #
I have an encrypted filesystem that I've decided I don't want encrypted anymore. Seems the easiest way to do this is simply reformat the filesystem, but I can't. If I try to do it in YaST2 I get either system error code -3005 (unknown) or -3008 (apparently in use). When I try to do it from the command line I get:
Code: frylock:/home/joel # umount /dev/sdb5 umount: /dev/sdb5: not mounted frylock:/home/joel # mkfs -t ext4 /dev/sdb5 mke2fs 1.41.9 (22-Aug-2009) /dev/sdb5 is apparently in use by the system; will not make a filesystem here! frylock:/home/joel #
It's unmounted, I don't know how to make it any less in use than that.I can't delete the partition because it's not the last logical partition in the extended partition.
During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.
I am using LVM2 Clustering to mirror logical volumes between 2 different storage arrays ( iscsi target hosts). Everything is up and running fine, but I would like to be able to monitor the status of the mirror(s), and "re-sync" them if necessary.
I have attempted the locate the information from Google. From what I have read, lvdisplay -v should tell me whether the mirrors are in sync, but it either is not, or I am simply miss reading it. I have come also across information stating lvchange -m [ 0 | # ] should be used to add or remove mirror copies. Is the is correct / only way to "resync" a mirror, in the event that I can determine the mirror is actually out sync?
For those who are familiar with Symantec's VERITAS volume manager, I am looking get the equivalent information related to plexes from vxprint, the equivalent function from /etc/vx/bin/vxreattach -br, and the progress information from vxtask list. I hope the information is currently "search challenged", or I am simply not fully comprehending what I have found.
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
I have successful upgraded my system from Lenny to Squeeze and have even installed NVIDIA Driver successful, as well as other applications that I need. My system is now running smoothly and okey. My applications are also running smoothly except Skype 2.2 (Debian Forum Guys are currently helping me solve it).
However, I do want to upgrade my file system to ext4 in order to take its advance features and advantages especially that my system is now in WORK HORSE mode. However, I am not confident enough to do it because the guide is limited and does not tackle the issue of a system using ext3 with LVM2 on it.
Therefore, my question is how do I migrate (LIVE) my Ext3 to Ext4 on my system that uses LVM2? A clear and understandable guide is highly appreciated especially that I am newbie on it.
I have no idea what I'm doing so here goes: I installed Fedora and clicked the "encrypted" box during the process. What I want to do now is "browse" the volume using "File Browser" but I only get messages like, "Unable to mount location, org.freedesktop.DeviceKit.Disks.Error.Failed: Not a mountable file system". Why cannot I not see the files? I have the password. I would like to be able to move, delete, rename, etc files but that seems impossible because I cannot access the drive.
This is my specific solution to my specific problem. After updating to Squeeze from my prior Lenny distro (amd64 with whole disk encrytion using LVM2, dm-crypt, LUKS) everything went well - at first. I was duped like so many, thinking that all was well and I could remove the legacy-grub (aka: Grub1) and just use grub-pc (aka: Grub2). As soon as I removed the legacy-grub and rebooted my laptop, I was confronted with:
GRUB Loading stage1.5 GRUB loading, please wait..Error 15 At this point I wasn't sure if it was a Grub problem or a deeper encryption problem - especially after reading that some people had missing packages in Squeeze (lvm2, dm-setup, initramfs-tools, etc.)
Okay, the solution for me.
1. download and burn to disk: debian-live-6.0.0-amd64-rescue.iso[URL]..
2. scroll to and press enter/return on: text rescue
3. choose a root directory - for example: /dev/blah/root (I wrote down the list of possible /dev/.... for reference - this helped me remember where and what I had partitioned in Lenny)
4. choose: Execute a shell in /dev/blah/root
5. once in the shell, I discovered I needed to mount a few of those partitions that I had written down in order to get access to grub-probe, update-grub, grub-install, etc. You may not have to if your partitions are minimal. I you need to use other partitions, type (for example):
i want to know that if i install linux on to my pc with SWAP/ boot as partition and after that i want to convert them to LVM2 type configuration .how can i do that.i want to create a system having logical volumes from that system without reinstalling these partitions should convert into two LV's LV 0 for root LV 1 for swap
Running 'zypper install lvm2-clvm' results in a message: Resolving package dependencies... Problem: nothing provides libcpg.so.2()(64bit) needed by lvm2-clvm-2.02.45-16.2.x86_64 Solution 1: do not install lvm2-clvm-2.02.45-16.2.x86_64 Solution 2: break lvm2-clvm by ignoring some of its dependencies So it cannot find the cpg library, which appears to be a part of openais (if I believe google). I have configured the following repositories:
What could be the problem here? Am I just missing a repository or is cluster LVM not supported on opensuse 11.3?
Playing with the Box, I deleted a Raid-0 partition intentionally, saved it, and reboot drops me to (Repair Filesystem#) prompt. I notice during boot-up that the box didn't find /dev/md0, which is expected.
So what's the recovery procedure, since I can't edit #/etc/fstab, permission denied.
#fdisk -l shows all other partitions.
Not much familiar with fsck/e2fsck, yet like to give it a try.
I am using Fedora core 10. I have changed my partition size of Linux from windows. After I finished resizing the partition, I rebooted my system to the Linux platform. While booting it gave me an error: repair filesytem #1: I don't know what to do?
I am facing a serious problem.I installed UBUNTU 10.04 and encrypted it during installation. I accidentally erased some of the necessary files from root folder. now the the OS is NOT booting.luckily i still have the encryption key i have some important documents in that drive (desktop folder).
PS: I have tried to run Live Ubuntu it shows the Root, but it does not enter any of the folder.
I was running ubuntu as a live cd and I wanted to format my pen drive into an ext3 filesystem. I put in sudo mkfs /dev/sda1, but know im thinking that sda1 was my HDD!! I removed the cd from my computer, and it wont boot up into windows anymore!The only thing that is giving me hope is that the mkfs took about 1 min to format whatever it was formatting (my pen drive or my hdd!!) and my hdd is 500gb big. Is there anyway that I could have accidentaly formatted my HDD?
I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog
I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:
And here my filesystem types:
This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.
I was looking in a dir I haven't used for a while (I use it for data storage) and found a directory was repeated - that is, two directories with the same name. I renamed one of them, on the assumption that one of them has a non-printing character in its name, and that worked without a problem, but ls -i lists their inodes as the same. ls -l says they both have two inodes (. and ..), and the files they contain have the same names. The inodes of the files is the same (that is, the inode of a file in dir A is the same as the file of the same name in dir B.) Each file in each dir is listed as having only one inode, but it's the same as that in the other dir.
