when I try to mount it in openwrt, it gives this error. mount: /mnt/data: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
in logs I see this: EXT4-fs (sdb1): couldn't mount RDWR because of unsupported optional features (10000)
after some search I see that the mount (or kernel) on openwrt doesnt support some feature on the ext4 partition.
and I have read that I eaither have to format the drive again or turn off that feature.
the drive is in TBs of data so formating it should be last option.
so can someone tell me if I can fix this with something like this: tune2fs -O ^metadata_csum /dev/sdb1
but that was for EXT4-fs (sdb1): couldn't mount RDWR because of unsupported optional features (400)
what should I put instead of ^metadata so I can mount it?
I have tried with another hdd that is btrfs and I have installed the kernel driver and btrfs progs and restarted router.
even with btrfs drive I get the same error for mount as: mount: /mnt/data: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.
