Hello,
Disaster recovery features described in the 2015's recovery guide for v2.x have not all been ported to 3.0. However, you can still use: * rbh-diff [--apply], to check/apply differences between the state saved in rbh DB and the filesystem. * use rbh-report or rbh-find to list entries on damaged OSTs * use rbh-undelete to recover a lost entry that has been previous archived.
