[Ocfs2-devel] Fail to mount an OCFS volume for the secondtimeunder kernel 2.6.

[Zhang, Sonic]

Hi,

	I checked some original svn versions of the OCFS2 source code, rev.810, =
815, 818, 819, 820, 821 and 823. All versions have the same bug under =
kernel 2.6 as the latest version.

Hi,

	I tried to mount the OCFS volume under kernel 2.4 first. Then, turn to =
kernel 2.6 and mount for the second time. The OCFS driver under kernel =
2.6 works well in this cases. It seems the bug is in the journal =
creation code which is used during the first mount operation. But, I =
fail to locate which code caused the different behavior between kernel =
2.6 and 2.4 by now.=20

	Do you have any opinions?

	Thank you.

Hi,

	I checked this bug on kernel 2.4. It doesn't occur.
	So, this bug is related to kernel 2.6 porting.

under kernel 2.6.

Hi,

	After check out the latest svn source, I found I fail to mount
an OCFS volume for the second time under kernel 2.6. The system will
halt if I do so. But, I remember I did it successfully in the former
version. I submitted it into the bugzilla.

See following details.

Steps:
1. create ocfs volume.
2. mount this volume.
3. umount this volume.
4. mount this volume again.

Results:
System halt with error information.
JBD: no valid journal superblock found
