EXT4 md raid show negative value in df -h, fsck failing

I have md raid ext4 with 20 devices, All the devices are in good condition. now, when ever I do df -h i see negative value under 'Available'. I tried to remount the raid with 'umount' & 'mount' but it didn't help. I was told to run fsck.ext4 /dev/md0 but I get error message: Filesystem has unsupported features, get newer fsck version.

so I installed e2fsprogs-1.43.1 and when I run ./e2fsck /dev/md0 I get tons of errors:

BackUp: Inode 222789841 block 696 conflicts with critical metadata, skipping block checks. BackUp: Inode 222789841 block 466 conflicts with critical metadata, skipping block checks. BackUp: Inode 222789841 block 470 conflicts with critical metadata, skipping block checks. BackUp: Inode 222789841 block 568 conflicts with critical metadata, skipping block checks.

BackUp: Inode 222789841 block 3531604892 conflicts with critical metadata, skipping block checks.

at the end it says it failed.
