[Ocfs2-users] ocfs2 goes to read only

Thu Mar 24 07:45:40 PDT 2016

Hi Team and Joseph,

  Ocfs2 file systems goes to Read Only mode when mount after reboot. we try fix with fsck but its aborted and thrown error" fsck.ocfs2: dir_indexed.c:1441: ocfs2_dx_dir_search: Assertion `entry_list-&gt;de_num_used &gt; 0' failed.". We are in critical situation please give us solution asap.
