bio too big device md0 (248 > 240) - lvm on top of raid1

bio too big device md0 (248 > 240) - lvm on top of raid1

[Jens Thiele]

Hi,

I think I run into the same problem as described in a thread on the lkml:
"[dm-devel] bio too big device md1 (16 > 8)"
Message-Id   <87irc84bcq.87hcrs4bcq@87fy7c4bcq.message.id>
http://lkml.org/lkml/2007/4/7/81

A related thread on dm-devel about a patch that probably doesn't help:
"[dm-devel] [2.6.22 PATCH 01/26] dm: merge max_hw_sector"
http://www.redhat.com/archives/dm-devel/2007-May/msg00007.html

Any news regarding this one?
Should I file a bug on http://bugzilla.kernel.org/ ?
(It seems there is no entry yet)

Anything I could do to help fix this problem?

Thanks
Jens

PS: if I have a LVM snapshot the message disappears

Yes,  if you can reproduce it, report it to bugzilla please.

Please attach kernel version, "dmsetup table", syslog... etc. 
(you can use lvmdump command to grab all informantion and
attach it to the bug).

so please describe this too with informations above.

"From time to time I connect an external usb disk, that is part of the same
raid and do an incremental resync. (md1 raid with internal bitmap)."

Should I mark my bug report as duplicate of #9401?
