[Ocfs2-users] Mount fails with error status -22?

[Sunil Mushran]

What version of tools are you using?

It appears that you formatted the device with ocfs2-tools 1.4
but now are accessing it with ocfs2 1.2. SLES10 SP1 ships
ocfs2 1.2 and SLES10 SP2 ships ocfs2 1.4.

The incompatible feature is "sparse file" that was provided in
ocfs2 1.4.

If you want to mount this volume in SLES10 SP1, you will have to
disable this feature using ocfs2-tools 1.4.

$ tunefs.ocfs2 --fs-features=nosparse /dev/sdX

The 1.4 user's guide explains how to enable/disable these features.
