From the xenstore dump I conclude that when you took it all backends were in 'closing' state. Unfortunately you didn't provide matched information about left over blkback threads: The driver switches a device to 'closing' only after having initiated termination of the respective thread, so (minus eventual bugs)

If that isn't the case, try turning on some debug messages (module parameter "debug_lvl") and/or printing of statistics (module parameter "log_stats"). Both parameters can be turned on via sysfs after the module was already loaded. If that doesn't get us further, we may need to sprinkle further debug messages around the blkback sources - would you be able to rebuild an eventual test kernel for yourself? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
