Thread: primary and backup superblock - Server, Laptop and VMware

-

hi,

have ubuntu 11.04 2 ext4 partitions. (i tested env. in server, laptop , vmware).

, fsck unmounted part. see if ok.

"fsck.ext4 -n /dev/sda1" , ok.

next step "dumpe2fs /dev/sda1" , read backup superblock.

"fsck.ext4 -n -b 32768 /dev/sda1" (block size 4096)

, lots of free block wrong ,
"group descriptor xxxxx checksum invalid. ignored."



start lots of different live distribution , tested /dev/sda1. same behaviour (partedmagic, suse, fedora).

why first (0) superblock ok ... backup ... lots of error?

best regards,
ruy
