It only takes a minute to sign up. Here's the command that ran successfully before restarting: Error reading block 63471616 (Invalid argument). Ignore error? yes. Force rewrite? yes. Error writing block 63471616 (Invalid argument). Ignore error? yes. Superblock has an invalid journal (inode 8). Clear? yes. Clear? yes. The filesystem size (according to the superblock) is 127047680 blocks. The physical size of the device is 22190080 blocks. Either the superblock or the partition table is likely to be corrupt! Abort? yes. Error writing block 63471616 (Invalid argument). Ignore error? yesDo you have a backup? Like I said, it's a new install so we really didn't have much of anything in our home directory. It's almost entirely what Redhat put there. Maybe I should be looking at how to remove that filesystem and start over. That's why it's not the default behavior. If not, and the data is important, I would image the partition (you can try running recovery tools like debugfs on the image). I included the results of -y because that's how it ended up when I went through line by line anyway. It might restore your volume group metadata. You can always read the lvm documentation in product guide. It has detailed explanation of the commands I am going to tell. Now, find the VG on which you ran the lvresize.You have to find out the file corresponding to your lvresize operation. Theoretically it should be the most recent one. Try to boot up with the backup superblocks which should be present if you have a working dumpe2fs output. Then Currently, your volume has shrunk, but the filesystem has not shrunk to match it. Do that, run fsck again, and you'll hopefully be OK. Please be sure to answer the question. Provide details and share your research.

It makes sense to me that the inconsistency is due to the server powering off unexpectedly.

Below you will see some of the more important options: These cods can be seen in fsck’s manual by running: In such cases you may want fsck to automatically attempt to correct the errors. This can be done with: Since you cannot run fsck while the partition is mounted, you can try one of these options: Use the following command: During the next bootup, the fsck will be performed. If downtime is critical, it is recommended to plan this carefully, since if there are many used inodes on your system, fsck may take some extra time. First prepare your system for reboot.Select the “ Advanced options ”. Select “yes”. If you have any questions about fsck, please do not hesitate to submit them in the comment section below.

This damage can prevent them from booting automatically. When an operational interruption occurs, the startup process prompts the user to enter the root password in order to repair the damaged file system. Give root password for maintenance (or type Control-D to continue): The default root password for V4 is Unidesk1. If not, use the instructions on the Installation topic under Secure the appliances to log in.

The problem is that you can get orphan inodes if a directory gets corrupted - the files are perfectly valid, it is just that the only directory they were in has been corrupted, and possibly deallocated. Whether the files should be deleted or not is not a decision that fsck can make automatically. Two valid recovery options.Inodes that get lost because the directory entry that should point to them is missing are a different matter. A problem with the orphan inode list is a much simpler matter, and one recommendation for fixing that is simply to mount the filesystem, since the orphan inode list is automtically cleared when the filesystem is mounted. Editorials, Articles, Reviews, and more. If you'd like to contribute. But nevertheless we must tru to repair file system. Also it is possible that your Linux node is not reachable so in such cases it becomes mandatory to boot into rescue mode and then perform repair of your file system. Troubleshooting Rescue a Red Hat Enterprise Linux system. Run a memory test. Boot from local drive. Return to main menu So we can safely repair filesystem in rescue mode at this stage. So, let me know your suggestions and feedback using the comment section. Comment Name. This is fine, except for one thing: if there's a large time jump backwards, the following error appears on reboot: IMAGE2: Superblock last mount time (Tue Mar 1 17:32:48 2011. IMAGE2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.Is there any way to either skip the check or force the check to happen automatically on reboot. Running fsck manually after setting the time doesn't work as the filesystem is still mounted at that point, and just disabling fsck entirely is less than ideal. I'd tried editing the last mount time on the disks using debugfs, which works fine for ext3 drives, but appears to fail inconsistently on ext4. This seems to be exactly what you need, and since you're using Red Hat Enterprise Linux 6, you should have 1.41.12, which includes this option.

I am only able to tell the user what to do over the phone. They are located to far away from me. So I'm left with two options. I have attached an image the user got for me. If user enters the root password, will that bring them to a shell term for doing various commands, or can they do it from this screen. What is needed to resolve this, step by step? SystemRescueCD does not require root password. SystemRescueCD does not require root password. It sounds like the best option would be to have them overnight their drive along with their latest backup tape, and I will try to get things working again and overnight it back. I just hate to think that they will be without a their server for a couple days. They backup the system to Tapes every night. So recovery is an option if worse gets worse. Is there any options to use for fsck, like -y.It can be really hard to assist over the phone and not be able to see the screen for myself. Hoping all works out. I sent the user some instructions on what to do. We still have the backup from the day before should things go south. It all looked successful, so I had user run shutdown -r now. After that, user is excited and claims things are working again. So we have ordered a UPS for them. It's important they have it to prevent this from happening again. Most our locations have a UPS on their servers, this situation is different because it's a bit tricky due to certain situations The only problem that fsck detected was that the list of orphan inodes had become corrupt, so there was nothing lost in the filesystem. Transactions that were in progress when processes were abruptly terminated would of course have been lost.

You can use the fsck command to repair corrupted file systems in situations where the system fails to boot, or a partition cannot be mounted. In this article, we will talk about the fsck command.When no FILESYSTEM is provided as an argument, fsck checks the devices listed in the fstab file. Never run fsck on mounted partitions as it may damage the file system. Before attempting to check or repair file systems always unmount it first. Check the manual pages for more information about a specific checker. If you don’t know the device name, use fdisk, df, or any other tool to find it. If you want to check or repair the root file system, you have several options at your disposal. You can set the fsck to run on boot, boot the system in recovery mode, or use a live CD. To run fsck in recovery mode: Enter the boot menu and choose Advanced Options Select the Recovery mode and then “fsck”. When prompted to remount the root file system choose “Yes”. Once done, resume the normal boot. To run fsck from a live distribution: Boot the live distribution. Use fdisk or parted to find the root partition name. Maximum mount count: -1. Last checked: Tue Jul 24 11:10:07 2018. Check interval: 0 ( )The value of 0 or -1 means that fsck will never run. “Check interval” is the maximal time between two filesystem checks. The root file system should have a value of 1, and all other file systems you want to be checked should have a value of 2. If you have any questions or feedback, feel free to leave a comment.

When you start it, it's in command mode, hit a, i or insert key to enter edit mode. Hit Esc to return to command mode and type:wq to write changes and quit. If yes, double check the VM's configuration to see if there's a drive missing or incorrectly configured. You could always boot a live distribution to double-check the machine's access to the HW (this will work on a physical machine as well as a VM) but IIRC, if you're using LVM or md RAID it generally won't be able to access the content of the drives without some additional configuration (could be wrong on that part, coffee still hasn't kicked in and the 4 yr old is watching Peter Pan while I patch windows servers) When you start it, it's in command mode, hit a, i or insert key to enter edit mode.

It uses a combination of built-in tools to check the disk and generates a report of its findings. Unmount the disks you intend to work on before attempting to check or repair them. You risk corrupting your file system and losing data if you run fsck on an active disk. Use with caution. Visit our Rescue and Rebuild guide for instructions on how to boot your Linode into Rescue Mode. If you’re working on a local machine, consider using the distribution’s recovery mode or a live distribution to avoid working on a mounted disk.If you are using Rescue Mode, the disk you want to check should not be listed: Unmount the disk from the Configuration Profile.
