Strange LV driver syslog message ?!?!?

[Luc Chouinard]

One of my servers (a 280s running 3.3.2) has loged a bunch of
strange messages in the SYSLOG.

It seems that the logical volume device driver encounters
a read error and then performs a mysterious (to me) action.

The message is :

May 14 02:42:21 physs1 unix: WARNING: chunkread: bad read ip 800F0920 off 9674752
May 14 02:42:22 physs1 unix: lv device 0: Extent list trashed, inode 27159
May 14 02:42:22 physs1 unix:

And there is no log from the SMD-DISK drivers, so it must not be a disk
problem...

Its the second time in a month that this happens.

Is it dangerous?
Should I do something about it?
