rootfs: ********** WARNING: Filesystem still has errors **********

It's only an sdcard, but does anyone know the way out of that?

You need to check the filesystem type on that card. How old is it? How it was used?

The filesystem is ext4. it's 4-5 months old, and it's the / filesystem in a RazPi 4.
mmcblk0p1 = 250M
mmcblk0p2 = rest of 32G

Yes it could be near EOL. But running badblocks with a write option takes all night and doesn't improve the SDCard any. The crazy thing is, the RazPi mounts it, whereas my x86 box won't. I had hoped for an expert on extX filesystems, but it seems not. I threw the error into DDG. This is from stackexchange:

I know this is an old thread, but, I figured I'd offer some insight.

This seems to be the way sd cards die a natural death. The number of read/write cycles sd cards can endure is substantially lower than most other mediums considered 'read/write'. When that has been exhausted, the card will go into read only mode, but won't inform you of such. Lots of things will think they're writing to the card thanks to OS caching, etc., but nothing ever sticks.

A great way to kill an sd card is to mount it as a swap partition or something that's very read/write intensive. You'd be surprised how quickly you can kill a card that way. I've found that running knoppix off of an sd card or usb thumb drive will only last a month or two, depending on the quality of the card and the intensity of knoppix usage. (I've since switched to running knoppix off of a usb SSD drive which has lasted a couple of years now).

It seems like I'll have to go to usb SSD. But I'll also have to go to 'noatime' on the remaining sdcards

EDIT: I fsck'ed /dev/mmcblk0p1 (the /boot partition) this morning and it was fixed. Now I can't mount it. It seems to have gone the way of all sdcards…

Going USB3 instead of mSDHC card, I think is a wise decision.

I'm running my RPi4 from an external HDD, it's almost as fast as from an SSD, so if you've got a spare around, worth a try.

Edit: If you decide on an SSD, you only need a cable to connect it, whereas, a HDD usually requires a case.

Earlier RPi needed an sdcard to boot. Probably it has been changed already.
