[Lustre-discuss] Assertion failur in ldiskfs_get_blocks_handle

[Patrick Winnertz]

Hey!

After reinstallation of an lustre testcluster with 1.8.1 one ost crashed with 
an Assertion failure in inode.c (running 2.6.18er kernel on amd64). 

Do you know such an issue or has anybody else met this error before?

Greetings
Winnie
