Hi - I'm trying out ext4 on a large 8.2 TB software raid device (md). On rebooting (cleanly unmounting), I tried an fsck on the device. I get the following: [root@...ck2 ~]# fsck /dev/md0 fsck 1.41.4 (27-Jan-2009) e2fsck 1.41.4 (27-Jan-2009) fsck.ext4: Group descriptors look bad... trying backup blocks... Group descriptor 0 checksum is invalid. Fix<y>? It then finds lots of bad group descriptors. This is Fedora 10, 2.6.27.21-170.2.56.fc10.x86_64 and e2fsprogs-1.41.4-4.fc10.x86_64.
