In the past few days my system repeats to set itself to read only. I've done some searches and apparently my drive might have gone bad? After a reboot I've been running fsck and say yes to everything and it works again for something between 24 and 48 hours.
Judging from my google searches the output of dmesg seems to be important:
[ 9563.932564] EXT4-fs error (device sda1): ext4_iget:4831: inode #26092049: comm dockerd: bad extra_isize 28448 (inode size 256) [ 9563.933915] Aborting journal on device sda1-8. [ 9563.935159] EXT4-fs (sda1): Remounting filesystem read-only [ 9563.935211] EXT4-fs error (device sda1): ext4_iget:4831: inode #26092049: comm dockerd: bad extra_isize 28448 (inode size 256)
Also this is my smartctl output for the drive, which also has been asked for in some threads:

I do sometimes not correctly shutdown my notebook. Sometimes its stuck after closing and reopening the lid so I need to force shutdown and generally I try to reboot as little as possible so most of my reboots in the past week might very well have been force shutodwn -> start again. I suppose this could very well corrupt the filesystem although it shouldn't destroy my ssd, should it?
I'd be very thankful if someone could help me with this. If my drive is bad I'm just going to buy a new one but since it's only 2 years old that seems rater unlikely to me.
edit: Okay apparently there is some problem with the ubuntu 4.19 kernel which I was using because my kernel version crashed the system whenever I started a java application. I updated to 4.20 now will report back in a few days if I still experience read-only or not!
