[Lustre-discuss] fsck.ext4 for device ... exited with signal 11.

[Craig Prescott]

Hi,

We are trying to fsck an OST that was not unmounted
cleanly.  But fsck is dying with this error after making some corrections:

[root at XXXXXX tmp]# fsck -f -y /dev/arc1-lv2/OST0003
...
High 16 bits of extent/index block set
CLEARED.
Inode 306602015 has an invalid extent node (blk 512, lblk 641536)
Clear? yes

Warning... fsck.ext4 for device /dev/arc1-lv2/OST0003 exited with signal 11.

It is repeatable.

So we are stuck.  We need to fsck our OST, but fsck is dying.  Can 
anyone give us some advice on how to proceed?

Thanks,
