[Ocfs2-devel] 答复: [QUESTION] How to recover a deleted file?
Hi Junxiao,
Thanks for you reply.
Unfortunately, the file was removed few days ago, and I cann't find the
extents tree with logdump command as the journal file had been rewrited.
I creat a file and remove it after a while, then the latest extents tree of
the file can be found with logdump command. In this situation, the file can be
restored.
Anyway, thanks again.
Changkuo.Shi

Umount the volume first, then use logdump of debugfs.ocfs2 to find the latest
extents tree of the file before it is removed. With this, you can copy the
removed file out. Good luck.

Junxiao.
