I get (The origin F was built with prior lvm2:1.0.5 dm:1.01.05) --- device-mapper ioctl cmd 3 failed: Device or resource busy Failed to suspend origin F Device '/dev/sdf11' has been left open. --- This is on stock FC4 kernel kernel-2.6.13-1.1532_FC4 I also tried on kernel-2.6.14-1.1637_FC4 but on that kernel, I get --- Attempt to close device '/dev/hda' which is not open. Attempt to close device '/dev/sda' which is not open. (& similarly up thru sdi -- all my disks) ..followed by the Failed to suspend.. stuff as above I had to configure both dm and lvm2 with "--disable-selinux"), but I wouldn't expect that to have any impact, eh? I've also been noticing that I've had to use "--ignorearch" to install FC4 precompiled kernels and --target=i686 on compiles from FC4 kernel srpms -- would that have any relation to these symptoms? I didn't do any kernel patching -- the only patches relate to the 2.4 kernel, I believe. In case there's something useful there, heres the tail of the spam when I set verbose=2 in lvm.coinf /dev/sdf11: lvm2 label detected Archiving volume group "VGf11" metadata (seqno 64797).
