Hi Team, While running "xe vbd-unplug" command against VBD which is used by VM, it should return an error. On XenServer 6.0, when I am doing it, I will get an error at 1st time, but when I do it again, it does not return error for 1200 seconds (20 minutes). I am getting timeout error after 1200 seconds. The error message on console Is:: The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem. message: Watch.Timeout(1200.) In logs: [20111214T00:49:27.381Z|debug|iida-dl018|611167 unix-RPC||cli] Xapi_cli.exception_handler: Got exception DEVICE_DETACH_REJECTED: [ VBD; OpaqueRef:2d1d0de6-be4c-c214-cade-d8e11d0e2365; 16 Device in use; refusing to close ] Dec 14 09:49:27 iida-dl018 xapi: [error|iida-dl018|611167 unix-RPC|VBD.unplug R:72e01c62a8be|xapi] Xapi_vbd.destroy_vbd got an error (frontend (domid=1 | kind=vbd | devid=51712); backend (domid=0 | kind=vbd | devid=51712)) 16 Device in use; refusing to close Dec 14 10:09:42 iida-dl018 xapi: [error|iida-dl018|611175 unix-RPC|VBD.unplug R:88079c7cb782|xenops] watch: timeout while watching xenstore after 1200.000000 seconds On XenServer 5.6 (Midnight Ride), I do not see this issue. Is there any change in the xapi?? What is the possible cause of the failure?? Is any work-around for this ??
