Lustre discuss - May 2010 - Ldiskfs corrupt

Hi, all

I had a old OSS server (running lustre-1.4.6)  failed. Dmesg reported
"LDISK-fs: journal inode deleted!" when mounting lustre device.Then I
tried
to mount it with ldiskfs option, it still reported same message. Can I get
data back through some other ways?Anyone can give me a help?

Run "e2fsck -f" with the latest Lustre-patched version of e2fsprogs to
fix this problem (and likely others as well).  If the journal inode is lost,
then you probably have other filesystem corruption.

Afterward, you can recreate the journal inode with "tune2fs -j
/dev/XXX".
