why do I get bad superblock on /dev/sda, missing codepage or helper program?

pl flag

Check this:

root@dev:~# lsblk -f|grep sda 
sda         ext4              1.0        21ca0461-0e80-4468-b942-3735e9fd4945                 
root@dev:~# grep /db /etc/fstab
​UUID=21ca0461-0e80-4468-b942-3735e9fd4945 /db       ext4     errors=remount,ro   0 1
root@dev:~# mount /dev/sda /db 
root@dev:~# ls /db
lost+found  postgres-old  postgresql 
root@dev:~# umount /db 
root@dev:~# mount -a 
mount: /db: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error. 
root@dev:~#

Why mount -a gives an error while simple mount doesn't?

Check `dmesg` for any relevant entries.

thanks, I have this in dmesg: `Unrecognized mount option "errors=remount,ro" or missing value` , looks like the correct is `errors=remount-ro`

I think this misleading message should be removed from `mount -a`

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.
