Bug#656899: mdadm: sending ioctl 1261 to a partition warnings
I'm also seeing this problem. I can trigger these errors trivially by
doing:
/sbin/lvcreate -A n -L500M -s -nvar-backup /dev/vg0/var
and
/sbin/lvremove -A n -f /dev/vg0/var-backup
Seeing lots of these two errors:
Mar 24 10:53:25 feynman kernel: [4198946.403294] mdadm: sending ioctl
1261 to a partition!
Mar 24 10:53:25 feynman kernel: [4198946.403510] mdadm: sending ioctl
800c0910 to a partition!
uname -a
Linux feynman.home.woodall.me.uk 2.6.32-5-686 #1 SMP Mon Jan 16 16:04:25
UTC 2012 i686 GNU/Linux
Additionally, the lvremove doesn't actually work first time if the
previous snapshot that was made was not of the same partition. I have
no idea if that is related but I wouldn't be surprised if it is.
I first saw the lvremove problem on Feb 1st. mdadm and linux-image were
updated on 29th Jan but I didn't reboot until 4th Feb
From kern.log backed up on morning of 5th Feb:
Reboot here:
Feb 4 19:54:43 feynman kernel: Kernel logging (proc) stopped.
Feb 4 19:54:43 feynman kernel: Kernel log daemon terminating.
First instance of this ioctl issue here:
