Failed To Find Sysfs Mount Point Lvm

Boot to rescue, mount the new root FS under /mnt and next FS under /mnt, make chroot.4. If it is Linux Related and doesn't seem to fit in any other forum then this is the place. Use it with extreme care. As such, it should be uncorrupted by 1.2 metadata, and it's mdadm --examine still returns the original info (when attached as the only extra hard drive): Code: /dev/sdc4: Magic : a92b4efc Check This Out

Grub works OK but then there come a lot of messages like that: "Waiting for device /dev/system/sys_root to appear. Menu Close Search SOLUTIONS Solutions Overview Unstructured Data Growth Multi-Vendor Hybrid Cloud Healthcare Government PRODUCTS Product Overview Backup and Recovery Business Continuity Storage Management Information Governance Products A-Z SERVICES Services Overview That was OK, but it activates itself only in read-only mode. I don't think the problem was the kernel update, the server had an uptime of 160 days at the moment I rebooted it, so the problem could happened days before but http://blog.grogscave.net/2016/06/recovering-from-vcenter-appliance-disk.html

You will see errors about an "unknown device" and missing device with UUID. I wouldn't normally recommend any random blog, but perhaps it's worth considering this one. I cant tell for certain if its immediate because so many mount messages are spewed and I am not sure how to 1) pause the screen or 2) scroll the screen Found volume group "VolGroup00" using metadata type lvm2 pvscan PV /dev/md0 VG VolGroup00 lvm2 [279,47 GB / 32,00 MB free] Total: 1 [279,47 GB] / in use: 1 [279,47 GB] /

  1. An important part of LVM recovery is having backups of the meta data to begin with, and knowing how it's supposed to look when everything is running smoothly.
  2. pvscan detects a UUID mitchmatch since PVCREATE overwrote the VolGroup00 vgscan and lvscan are also useless.
  3. Blogger Theme by BlogTipsNTricks Gimpster & His Boring Blog Making all other blogs seem exciting!
  4. Found volume group "mint-vg" using metadata type lvm2 sudo vgdisplay -v gives: Finding all volume groups Finding volume group "mint-vg" --- Volume group --- VG Name mint-vg System ID Format lvm2

  7. Once you have an image file you could try repairing the file system or use testdisk.
  8. Without /var /opt and /tmp they are usually less then 4GB and if you allocate, say, 32GB to root partition chances that you even run of space during the lifetime of
  9. Falling back to internal scanning.

GRUB screen appears & when I chose to boot normally it gets struck at "Target filesystem doesn't have /sbin/init" error, as in: mount: mounting /dev/mapper/mint--vg--root on **** failed: No such file Some information about the recovery process There are very few good articles on the Net that describe the nuts and bolts of the recovery process. I listed /etc/fstab. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant.

After a few interactions we use ctrl-Break to break out, but it is too late. yes /dev/sales/reports: ***** FILE SYSTEM WAS MODIFIED ***** /dev/sales/reports: 835/131072 files (5.7% non-contiguous), 137213/262144 blocks Mount the file system and recover as much data as possible.

Carmen_POctober 22nd, 2014, 05:26 PMI tried to access LVM from a LiveCD as mentioned on http://dannytsang.co.uk/mounting-lvm-using-ubuntu-live-cd/ I typed in the following commands sudo apt-get install lvm2 sudo pvscan sudo vgscan sudo Use this to add a journal to an ext2 system, making it an ext3 system, as well as display or set the maximum number of mounts before a check is forced. As filesystems get larger and larger, this takes longer and longer, even though disks also keep getting faster, so a full check may take one or more hours. NOTE: If the missing disk contains the beginning of the file system, then the file system's superblock will be missing.

I hope you backup. https://forums.gentoo.org/viewtopic-t-806467-start-0.html Ok, how much space do I need for storing that image file, is it a. 225MB, which was the total amount of data on my system before failure b. 160GB which Testdisk could also potentially recover and repair that root partition.

So after the post above, I kept looking for more information about RAID, LVM and related things. his comment is here Also, Backup your files now! Show 12 replies 1. I will try it again and post the log or more information.micy01 Like Show 0 Likes (0) Actions 3.

The same FIT flash drive can contain a tar ball of major filesystems as provided by Relax-and-Recover. Thanks for the suggestion. I use the command dd to extract the first part of the partition and write it to a text file: dd if=/dev/md0 bs=512 count=255 skip=1 of=/tmp/md0.txt Open the file with a this contact form See below.

I followedhttp://www.opvizor.com/blog/vmware-vcenter-server-appliance-vcsa-filesystem-is-damaged/ to get out to a BASH prompt, but the filesystems that I was getting errors for were on LVM volume groups.

If you do not have enough disks buy them ASAP. By the moment, I could start the server with the rescue CD, chrooted and started every process manually so the users can work during the week, all the data is perfectly Is very important to have this server working flawlessly because is the main data server of the company. This line seems improperly modified as you correctly pointed out.

Tools for Reiserfs filesystems reiserfstune Displays and adjusts parameters on ReiserFS filesystems. Linux and UNIX filesystems usually have a superblock, which describes the filesystem metadata, or data describing the filesystem itself. This is a great time to feel good knowing you have a solid backup to rely on. http://3swindows.com/failed-to/failed-to-mount-cf-card-system-dead.html Recovery actions should be attempted only on DD-image, never on damaged disk.

Only one of them (disk #1 which should be intact from the original array). Symptom 1: Attempting to activate the volume group gives the following: ls-lvm:~ # vgchange -ay sales /dev/sdc: Checksum error /dev/sdc: Checksum error /dev/sdc: Checksum error /dev/sdc: Checksum error /dev/sdc: Checksum error Let me know if that's OK or post whatever variation you prefer and I'll amend the title for you.

Fix /etc/fstab, fix /boot/grub/menu.lst, execute "grub-install /dev/sda", execute mkinitrd ( with the option "lvm2" too).5. No attempt will be made to address the data on the unrecoverable disk; this topic will be left to the data recovery experts. Another point of information for you: Issuing sudo mount -t ntfs /dev/mint-vg/root /media/recovery gives: I didn't knew about file_systems so I chose not to format entire disk as ext4 & let I'm not going to put the dd command out here.

Listing 4. When a disk is accidentally removed or damaged in some way that adversely affects the logical volume, the general recovery process is: Replace the failed or missing disk Restore the missing Data blocks and inodes each take space on a filesystem, so you need to monitor the space usage to ensure that your filesystems have space for growth.
