After installing OCFS2 und mounting the "shared storage" in both nodes (Hostnames = node1 & node2) I have tried To perform a simple test (copying and/or editing a file from node1 and read the same file on node2). I am getting the following errors: [root@node2 ORCL]# dmesg | tail -15 sde: assuming drive cache: write through sde: unknown partition table NET: Registered protocol family 10 Disabled Privacy Extensions on device c0376de0(lo) IPv6 over IPv4 tunneling driver divert: not allocating divert_blk for non-ethernet device sit0 Hangcheck: starting hangcheck timer 0.5.0 (tick is 30 seconds, margin is 180 seconds). eth0: no IPv6 routers present eth1: no IPv6 routers present (2868,0):ocfs2_check_dir_entry:1721 ERROR: bad entry in directory #16923: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 (2909,0):ocfs2_check_dir_entry:1721 ERROR: bad entry in directory #16923: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 (2910,0):ocfs2_check_dir_entry:1721 ERROR: bad entry in directory #16923: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 (2911,0):ocfs2_check_dir_entry:1721 ERROR: bad entry in directory #16923: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 (2918,0):ocfs2_check_dir_entry:1721 ERROR: bad entry in directory #16923: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0, name_len=0 (2918,0):ocfs2_empty_dir:305 ERROR: bad directory (dir #16923) - no `.' or `..'
