When i do this via console it works flawlessly but in omv i get the following error:. I cannot see anything in the logfiles.

I tried tail -f on all known logfiles but never see anything regarding this error. Why is it not possible to mount this volume? Greetings ion-fan. I've followed your instructions but all three possibilities failed. See following code:. Does anyone have a clue why this is not working? It must be possible to mount a normal ext4 partition Is there some info missing? Do i have to upload other debugging-data? If that doesn't work, maybe the journal is missing all together.

Do the following and mount: fsck. After that and also after the fsck-check the mount didn't work through openmediavault. Is there maybe a log were more precise infomation is given what fails? I think is a feature disabled in the kernel of the defaults options of ext4. Does dumpe2fs displays all available features? You have unsigned, ATM i am not able to give you an answer about if that's the problem or not.

I'll have to dive into the ext4 manual. Don't know if ryecoaaron knows the answer.

You have to make a file system on your array. The raw array is just a block device, which can hold any kind of file system, or non file system data. To make a filesystem, you can issue sudo mkfs.

Every XFS filesystem has a supposedly unique ID stored on-disk, which protects you from accidentally mounting the same filesystem multiple times.

To work around the issue, you can either use the XFS-specific nouuid mount option to temporarily ignore the duplicate check, e. Sign up to join this community.

I have a different process for this that replaced the bad superblock with one of the alternatives.

You can sudo yourself silly or just become root for the process. Just remember that when you are root, Linux assumes that you know what you're doing when you issue commands. If so directed, it will speedily delivery Mr.

Bullet to Mr. Like many other things, with great power comes great responsibility. That concludes my warning on running your system as root. Do not assume it's EXT4. Get your error message which says the superblock is bad. You don't want to do this if your superblock is OK. Pick an alternate superblock - keep in mind that the first one is the default and its bad so let's not use that one. You will also want to pick one from the list you get from your partition.

Do not use the example. Your superblocks may be stored elsewhere. Reboot and see if this worked. If not try the next superblock on the list. I've had to go the third or fourth one a couple of times.

Now try the command to validate the disk again. See if you get the same messabout about bad superblocks. Keep trying until you either run out of superblocks or it works. If you run out, you likely have bigger issues and I hope you have good backups. You can try running FSCK at that point. Warning : this might delete files you have saved. So you can run ls to make sure you don't lose important saved files and backup these files before execution.

Before we do that let's get a current state of your system. Please do not reboot or do anything else to change the system state once we start using this information or your data is at risk. If anything changes at all, please advise. Data at risk if I repeat.

You have me worried now. Sorry for such ridiculous question I am asking, but as you said before, I have to be really careful I think your array is started and should have data.

We absolutely do not want it to rebuild, resync or any other operations. So don't click on any "fix" buttons in the GUI. I am now trying to make sense out of this. But i lost my config on the server so i can not see the data in shared folder There is no server config on Synology, it all comes from the array itself.

No problem, conservative is good when dealing with arrays.

Report back on status. Ok, still investigating: vgdisplay lvs lvm vgscan lvm pvscan lvm lvmdiskscan. That all looks ok. Hmm that didn't do anything useful. Generate serial number from product.
