Description of problem: I have the importer remove all imported GNBDs and then right afterwards have the exporter remove all it's exported GNBDs. The gnbd_export -R ends up failing sometimes with this error: gnbd_export: ERROR remove request failed : Success From syslog: gnbd0: shutting down socket exitting GNBD_DO_IT ioctl It's still there: [root@morph-01 root]# gnbd_export -l Server[1] : sda -------------------------- file : /dev/sda sectors : 4294950912 readonly : no cached : yes timeout : no If a wait a little while the remove will then work. [root@morph-01 root]# gnbd_export -R gnbd_export: removed GNBD sda Version-Release number of selected component (if applicable): gnbd_export DEVEL.1103064972 (built Dec 14 2004 16:57:46) How reproducible: Sometimes
Gah!! I can't see this one either. But 20 to 1 says that the issue is that when you remove the device, It closes the connection to the server, but the server process isn't instantly cleaned up. It has to see that the client logged out, and shut inself down. This takes a second... or less. If the server tries to remove the device while this is happening, It should error out with "device or resource busy". I fixed the error printing code so that it will actually print the correct errno message. Personally, I would call this good enough. If it is taking more than a couple of seconds to remove, or if the error message doesn't now say "device or recouse busy" or something to that effect, then I need to fix something. Otherwise, I don't see this as an issue.
I guess we're calling this fixed enough.
fix verified.
