The file was removed by 'fsck.reiser4 --fix' which emmitted a message about deleting a corrupted file. (Case 2 in your list). This always happened after a system freeze or power loss. The machine freezes quite frequently - I think it has a DMA problem. Nevertheless I don't see how a file that was not written to can get corrupted. Current kernel is 2.6.20.5 (the reiser4 patch I submitted to this list on may 2nd). Root is mounted rw,noatime,nodiratime,onerror=remount-ro,tmgr.atom_max_age=60 Hope that helps. -- Ingo Bormuth, voicebox & fax: +49-(0)-12125-10226517 public key 86326EC9, http://ibormuth.efil.de/contact
