I just installed linux fedora 14 on my hp probook 4320s with installation CD with this name: Fedora-14-x86_64-Live-Desktop. Then I installed it on the hard disk. During installation I chose to encrypt hard disk. When I try to access my hard disk it says "unable to mount 250GB LVM2 Physical Volume, Not a mountable file system". What can I do to get access to my hard disk?
View 4 RepliesWhen I installed Ubuntu, I created an 52 gb encrypted partition which shows up in the disk utility, and in the window that opens when I click on the "home folder" icon. I get my normal windows partition, and under that the 52 GB LVM2 partition. But when I try to access it, I get this error.
Unable to mount 52 GB LVM2 Physical Volume - not a mountable file system
This is what fdisk -l shows

Partition 1 does not end on cylinder boundary.
/dev/sda2 52 30452 244193280 7 HPFS/NTFS

How can I fix this, and be able to access that 52gb partition? This is only my second day that I work with Ubuntu, so If more information is needed then let me know
I have a 500GB hard disk, /dev/sda. On it, there is /dev/sda1 for /boot, /dev/sda2 for an LVM PV (physical volume), and /dev/sda3 for another /boot (multiple Linux distros, one boot partition for grub legacy, another for grub2). so the LVM2 partition, /dev/sda2, is taking up ~465GiB. I want to add another OS (non-Linux), so I resized the *lvm2 physical volume* to 320GiB, successfully, using pvresize.
However, I now need to resize the partition so the lvm2 physical volume only just fits on it, ie to 320GiB. My plan of action is to use gparted (the partition table is GUID, so fdisk won't work), to first delete the partition from the partition table, then re-add it but this time with a smaller value (~320GiB). The problem is that I need to know exactly how many MiB/cylinders the physical volume is taking up. So, I run:
Code:
root@sysresccd /root % pvdisplay
--- Physical volume ---
PV Name /dev/sda2
VG Name vg0
[code]....
What one of these values do I need to set the new lvm2 replacement partition to?
I have a 160GB harddrive with 2 partitions:
1. /dev/sda1 ext2 100MB (this is my /boot partition)
2. /dev/sda2 LVM2 Remaining space (this is my physical volume and is LUKS-encrypted)
There is 1 volume group, slackvg, and 3 logical volumes:
1. swap 2GB
2. root jfs 10GB
3. home jfs 50GB
I would like to shrink /dev/sda2 to make room for another regular partition, is this possible?
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.

View 2 Replies View RelatedSo I got a bad physical volume inisde my logical volume. I want to do this safely rather than tinkering around, how can I get the bad physical disk out and look at the data on the other 2 drives to see if I can save anything? Its just the standard fedora setup where it combines all the disks, nothing fancy.
I have the volume group activated as a partial, and now I just want to see the data on the other sections how could I mount that?
I was trying to remove the physical volume from an old drive. So I opened gparted and told it to rewrite the partition table. The only problem is I targeted the wrong volume, I wiped the partition table on my 4tb raid5 array This 4tb array has everything! All my movies, tv shows, music. The only things I have backup up off site are my smaller files like documents. I was about to lose my whole media collection.
I did some research and found a solution that I will post here in the hopes that someone will google "I deleted the partition table on my lvm" and be find the solution.You should find in your filesystem a /etc/lvm/backup folder. LVM puts a copy of the crucial lvm information there every time you change the the volume group.
In this folder you will find a file for each volume group. In this file you will find the uuid for all of the physical volumes that make up that group.The first step is to recreate each physical volume with their original uuids. In my case I had only 1 physical volume, which was my raid5 array. My recreation command looked like this:
pvcreate --uuid cLrY02-zrVi-D0Vi-cIPB-6fF5-ed0c-XFF0os /dev/md0
Now I have a physical volume with the same uuid it had before. It is essential that you correctly match up the uuids with the correct physical deviecs.The recreated pv is empty, the volume group needs to be recovered. This is done by using a special tool and the backup file. For me the command looked like this:
vgcfgrestore --file /etc/lvm/backup/raid5 raid5
This tells it to recreate the volume group using the information in the backup file. The backup files looks for the uuid of the PV, which now matches the correct volume. The coordinates in the backup file match up to the data on the array an suddenly everything is back!
When I deleted my LVM partition table I did not damage any of the actual volumes on the volume group, I just wiped out the table of contents. The backup file had the information needed to rewrite this table of contents.

I'm trying to reinstall ubuntu because I messed up a bunch of stuff but I need to back it up on this hard drive which won't mount in any linux distro.
I didn't have Linux until the day Windows crashed on me for the gazillionth time. I was simply playing some music in Windows Media Player as the entire PC froze. No CTRL+ALT+DEL, no alt F4... so I was forced to hard-reset my computer using the ON-button. After that it never launched Windows again simply because it didn't feel like it. Now, we're not here to find out why Windows is a bitch about all this, my real problem lays somewhere else. Seeing as a lot of important files were on my Windows drive I figured I could just install Linux on the other drive and fetch the files from there. The problem is I can't. Every time I attempt to open the disk I get the following error:
Quote:

Hibernated non-system partition, refused to mount. Failed to mount '/dev/sda2': Operation not permitted. The NTFS partition is hibernated. resume and shutdown Windows properly, or mount the volume 'read-only' with the ro-option. Or mount the volume 'read-write' with the remove_hiberfile-option.
Code:
mount -t ntfs-3g /dev/sda2 /media/disk -o remove_hiberfile
I've tried both the ro-option and the remove_hiberfile but in both cases I'm given this error in the console:

And thus looping me back to the first command, upon entering I will again receive the first error. Things I have tried:
- said commands or slight variants
- re-installing windows (gets stuck during installation)
- used the Ultimate Boot CD in an attempt to access and copy the files from my Windows Drive onto an external hard drive / my Linux drive
- clicking the Drive icon furiously for a period of time in hope of a different result (which obviously did not work) Seeing as I can't screw open my laptop and take the drive out I'm really hoping there is some way for me to connect to the drive from Linux and extract the files.
- most likely my Windows system files have gone corrupt and I will need a format, but I'm not willing to do that unless I'm a 100% sure there is no way for me to extract the files first. I have an Acer ASPIRE 7720G (laptop) running an Intel Core Duo T7500 and have 2 physical hard drives (each as one large partition) of 500GB, further more it has 4GB DDR2 RAM memory and a fancy graphics card.
We had to reboot a server in the middle of a production day due to 99% iowait (lots of processes in deep sleep waiting for disk iops). That's never happened to us before. It had been 363 days since the last fsck, so it started automatically on reboot. It hung at 4.8% on a 2TB LVM2 volume for about an hour. I killed the fsck and rebooted the server. The second time, it went past that point and is currently at about 62%. First, what causes e2fsck to hang like that? Second, is there any danger in killing e2fsck, rebooting, and starting it again?

I find it strange that fdisk sees the drive but mount doesn't.
I made a mistake with lvm2 on centos 5.2.
I used parted to create a partition inside the logical volume, and then merrily used that partition, which appeared as /dev/pv-whatever/lv-whateverp1
Of course I created the FS as ext3.
So, after a reboot, I can't access anything in that logical volume with standard tools, as /dev/pv-whatever now only has the lv-whatever special file inside.
I can look inside the LV with parted fine, but parted can't copy ext3 filesystems.
Is there any way to get the data out of a partition created INSIDE a logical volume if that filesystem is ext3?
I believe server section is the best when speaking of RAID stuff...
I have the following situation:We have a DELL T3400 with embedded fake raid on it. I dont know exactly how the system was setup (I wasnt here at that time), but the RAID was enabled in bios and while booting, the two harddrives would be seen as members of intel raid volume0 (RAID 1 mirror). I am not sure if the software raid was actually properly configured in Linux (Fedora 9) and if the OS was reconstructing the whole raid or it was just the bios part that was mirroring the /boot or just some parts of it. Frankly I find these hydrid raids very confusing.Some bad disk manipulation from my part caused the server to crash, but I was able to recover and boot just with one hard drive after using fsck.
I decided to get rid of the raid as it's not the right solution for the application we need it for and decided to go for a traditional single harddrive system and to use Ghost for Linux to clone to a spare disk when backups are needed.So I installed the latest Fedora 12 distribution onto another harddrive and disabled RAID in bios (changed from RAID ON to autodetect, which is the only other option).
Here is what I have now:
/dev/sda has the newly installed fedora 12
/dev/sdb is an empty harddrive that I would use as an intermediate
/dev/sdc is the old harddrive member of intel raid volume0
sdb was partitioned into sdb1 sdb2 and sdb3 and I created an ext3 filesystem on sdb2. The hard drive belonging to RAID volume0 (sdc) has a lot of work done on it and I would like to be able to recuperate the files to the new disk (sda). I cannot mount that old harddrive while in fedora 12, as it sees some unknown raid member filesystem on it probably assigned by the intel raid chip.
So I decided to do it from the other side: to boot from raid volume 0, and from there mount a third intermediate harddrive (sdb) onto which I would copy the documents and then mount the same harddrive from the newly installed fedora 12 and copy those documents from that intermediate harddrive.I can mount /dev/sdb2 from fedora 12 fine and copy stuff to and from it, but not when I boot from the RAID volume 0 harddrive (sdc) with fedora 9 on it. It keeps saying that the partition in question (/dev/sdb2) is an invalid block device.I am stuck here, as my knowledge in this sort of things is very limited.If somebody can indicate me how to recuperate files from that old raid harddrive onto the new fedora 12 drive, I would appreciate a lot.
I was running through a fairly routine Gentoo install on a 160G hard disk. My intention was to have two partitions on the disks: one for boot, and one to be an LVM physical volume. In a stroke of absent-mindedness, however, I forgot to create the boot partition and only created the LVM physical volumend didn't realize ituntil the end of the installation.Anyway, I just want to shrink the physical volume partition and add in another partition with fdisk. However, this doesn't seem to be working the way I intend. I ran
Code:

I want to be able to add a physical drive to an existing filesystem, and PRESTO! That filesystem has more storage and/or redundancy. When one of the physical drives eventually fail, no problem, Ive lost some redundancy, I just have to install a new drive before another one fails.Lets assume I have 4 physical drives.*What Is This Configuration? *[URL]...But I am unclear how to get a logical volume that is mirrored and linear.
The last time I tried software RAID 1 (dm-x) under lvm, it was very fragile. Systemd could not start it,and then an update to mdadm put a stake through its heart. So I know that does not work.
Let's assume I have a volume group (VG) with six physical volumens (PV) - sdb1, sdb2, sdb3, sdc1, sdc2, sdc3..I want to remove one of the PVs from the group in order to use its space elsewhere - how can I know if it's safe? How can I do that without losing data and without first "pvmove"ing it elsewhere?Reading a bit more, my guess is using the result of pvscan, but I thought I'd ask before removing keeping it safe as I'm not an LVM expert.
