Hello, after a power outage I had one of my OSTs (total of 60) in an unhappy state.
Lustre version 2.4.1 I ran then a FS check and here follows: e2fsck 1.42.7.wc1 (12-Apr-2013) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Unattached inode 25793 Connect to /lost+found<y>? yes Inode 25793 ref count is 2, should be 1.

So basically I lost all data on the OST. Any hints on how could I recover it ? thank you.
