[Ocfs2-devel] A possible bug in kernel 2.6 porting

[Ocfs2-devel] A possible bug in kernel 2.6 porting

[Zhang, Sonic]

Hi,

When mount an OCFS volume for the first time, the delay before the mount
succeeds is much longer than that under kernel 2.4. Normally, it takes
more than 3 minutes under kernel 2.6, while it is only several seconds
under kernel 2.4.

I think this is a bug in kernel 2.6 porting.

In mount volume we let the nmthread loop OCFS_HEARTBEAT_INIT
times before signaling the mount thread via the osb->nm_init_event
wait queue. This is done inorder to stabilize the nmthread.

This should be the obvious place to start the investigation.

Or you could hit alt-sysrq-t during the mount to see where the mount
thread is "lounging".
