Can't mount drive without using e2fsck every boot

vg flag
halpplz

If i want to mount this drive, i need to run e2fsck or fsck.ext4 after every boot. All data is visible and accessable after that.

uuid only appears in system listings after "fsck.ext4" or "e2fsck". The uuid appearing after "fsck.ext4" is inside fstab and after "sudo mount -a" it mounts successfully. But next boot i have to do "fsck.ext4" or "e2fsck" and mount again.

I remember accidentally deleting one small first partition on this disk through gparted usb. This is probably the reason for this behaviour, right? How to solve this problem?

As requested by heynnema, i want to notice that i switched to ubuntu live usb and below is not the same disk constellation as everything above, i plugged some drives in and out.

In this case (fdisk below before fsck) i have this problem with disks /dev/sdb, /dev/sde and /dev/sdf

You can't mount or fsck a device like /dev/sdb. You must use partitions like /dev/sdb1. You can't fsck a partition if it's mounted. If you dual-boot with Windows, and you have a Windows driver installed that will let you read/write to linux ext/2/3/4 partitions, uninstall it asap, as it'll corrupt linux file systems all the time.

Thank you for commenting. "You can't mount or fsck a device like /dev/sdb. You must use partitions like /dev/sdb1." No this is not true, i can mount it after fsck.ext4 and there is no dev/sdb1 "You can't fsck a partition if it's mounted. " yes true i never did that "if you dual-boot with Windows, and you have a Windows driver installed that will let you read/write to linux ext/2/3/4 partitions, uninstall it asap, as it'll corrupt linux file systems all the time." Ok i am not using WSL anymore, only linux... still same problem

What version Ubuntu? If you look at **most** of the commands in your question, most fail, mostly with superblock issues... that's because you specified /dev/sdb.

To properly fsck a file system, here's the correct way...

  • boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Update #1:

Backed up data. Reformatted the drive. Partitions are now present. It all works again.

I have 2 disks with this problem. After running fsck, one says "ext2fs_open2: Bad magic number in super-block fsck.ext2: Superblock invalid, trying backup blocks..."Other Disk sometimes says more after that "Superblock needs_recovery flag is clear, but journal has data. Recovery Flag not set in backup superblock, so running journal anyway." After that both awaits confirmation for alot of fixes. Second time fsck no errors. After reboot both disks same problem/errors as if fsck did nothing at all.

@halpplz Were you booted to a Ubuntu Live USB? Please tell me the EXACT fsck command that you used. Edit your question and show me `sudo fdisk -l`.

I i am on Ubuntu Live USB. I followed EXACTLY your instructions. I used "sudo fsck -f /dev/sdb". I updated question with sudo fdisk -l

@halpplz What a strange looking disk configuration. Were these disks init/format/built under WSL? I don't see partitions on most of them. I don't know WSL, so I can't explain why these disks look the way they do... but since you're apparently not using WSL any more... you may have to backup any data on sdb and reinit/reformat/rebuild sdb using standard Ubuntu procedures to get your problem fixed. Sorry I can't be of more help. Have you looked at the SMART data for sdb?

@halpplz Is halpplz a reference to the movie Fifth Element?

No, they were not created in WSL. I think the problem either was my mistake by deleting partitions on these drives or wsl really corrupted them. Now, because there seems to be no solution for my porblem, i just moved the files on another empty drive and reformatted and rebuild them so there is a 1 behind the device name e.g. sdb1.Everything working fine so far. Nevertheless thanks for your help. I did not watch this movie, should i watch it?

@halpplz Yes! Now you get what I was talking about. Partitions... like sdb1. Your drives didn't have those until you reformatted them. And yes... watch "The Fifth Element" when you can. But... watch it from beginning to end... and then tell me if it isn't one of the best choreographed movies you've ever seen... and that the acting was great... esp from Mila J. And watch for the halpplz scene.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
