linux ubuntu mount bash

I'm deploying to production and Could someone explain I tried several approaches but none seem to work. After upgrading my kernel on Ubuntu 22.04 from version 5.15 to 5.19, I'm working with issues while trying to mount an existing ext4 partition. I get the behavior message `mount: /dev/sdb1: invalid argument` whenever I attempt to mount it using the command `sudo mount /dev/sdb1 /mnt/mydisk`. The partition was previously functioning correctly before the upgrade, and I haven't changed any of its settings or configurations. I've checked the partition with `sudo fsck.ext4 /dev/sdb1` to ensure there are no filesystem errors, and it reports that the filesystem is clean. I also verified that the kernel supports ext4 by running `cat /proc/filesystems` and confirmed that ext4 is listed. My fstab entry looks like this: ```fstab /dev/sdb1 /mnt/mydisk ext4 defaults 0 2 ``` I tried mounting it without the `defaults` option as well, but that didn’t help. Additionally, I tried mounting it with different options: ```bash sudo mount -o ro /dev/sdb1 /mnt/mydisk ``` This resulted in the same `invalid argument` behavior. Is there something new in the kernel version that might be causing this? Could this be related to the upgrade process, or is there something else I'm missing? Any insights would be greatly appreciated. What's the best practice here? For context: I'm using Bash on Linux. I recently upgraded to Bash 3.10. What's the best practice here?
