... the xfs_repair process did succeed. But in the end I still cannot mount the volume. In the following there is a log of my actions with the appropriate syslog messages. The xfs_check (see below) says that there is a bug in xfs. So I am writing to this list a second time asking for help :) Thanks, Kevin [xfs_repair: after 500 screens of dots...] .................................................................found candidate secondary superblock... verified secondary superblock... writing modified primary superblock sb realtime bitmap inode 18446744073709551615 (NULLFSINO) inconsistent with calculated value 129 resetting superblock realtime bitmap ino pointer to 129 sb realtime summary inode 18446744073709551615 (NULLFSINO) inconsistent with calculated value 130 resetting superblock realtime summary ino pointer to 130 Phase 2 - using internal log - zero log...
