I use sdparm (sdparm -C stop /dev/sdb) to spin-down one of them. It works fine and I can hear the disk spinning down and all...But when I run any LVM command, say lvscan or whatever, I get lots of error messages: <div style="margin: 5px 20px 20px;"> <table width="100%" border="0" cellpadding="3" cellspacing="0"> <tbody><tr> <td class="bbcodeblock" style="border: 1px inset ;"> > lvscan end_request: I/O error, dev sdb, sector 20971839 end_request: I/O
