When frontend receives the notification it tries to release\nthe disk in blkfront_closing(), but at that moment the disk is still in use\nby guest, so frontend refuses to close. Specifically it sets the disk state to\nXenbusStateClosing and sends the notification to backend - when backend receives the\nevent, it disconnects the vbd from real device, and sets the vbd device state to\nXenbusStateClosing. The backend disconnects the real device/file, and any IO\nrequests to the disk in guest will end up in ether, leaving disk DEAD and set to\nXenbusStateClosing. When the guest wants to disconnect the disk, umount will\nhang on blkif_release()-\u003exlvbd_release_gendisk() as it is unable to send any IO\nto the disk, which prevents clean system shutdown.\n\nSolution:\nDon\u0027t disconnect backend until frontend state switched to XenbusStateClosed.\n\nSigned-off-by: Joe Jin \u003cjoe.jin@oracle.com\u003e\nCc: Daniel Stodden \u003cdaniel.stodden@citrix.com\u003e\nCc: Jens Axboe \u003cjaxboe@fusionio.com\u003e\nCc: Annie Li \u003cannie.li@oracle.com\u003e\nCc: Ian Campbell \u003cIan.Campbell@eu.citrix.com\u003e\n[v1: Modified description a bit]\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n" }, { "commit": "8ded371f81fba8b38a049f8c5f30ce6438fc7b75", "tree": "0684d176cb6f35c92c4bf0185b1af9f5380077eb", "parents": [ "096a705bbc080a4041636d07514560da8d78acbe", "07d0c38e7d84f911c72058a124c7f17b3c779a65" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 10:38:18 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 10:38:18 2011 -0700" }, "message": "Merge branch \u0027for-3.1/drivers\u0027 of git://git.kernel.dk/linux-block\n\n* \u0027for-3.1/drivers\u0027 of git://git.kernel.dk/linux-block:\n cciss: do not attempt to read from a write-only register\n xen/blkback: Add module alias for autoloading\n xen/blkback: Don\u0027t let in-flight requests defer pending ones.\n bsg: fix address space warning from sparse\n bsg: remove unnecessary conditional expressions\n bsg: fix bsg_poll() to return POLLOUT properly\n" }, { "commit": "a7e9357f10744c3392ce3cd735c690ee513c7375", "tree": "b666d2ffb65a34014f8cdb8817172842d44d4496", "parents": [ "b4726a9df270859898e254b6eee67a28f38b34d3" ], "author": { "name": "Bastian Blank", "email": "waldi@debian.org", "time": "Wed Jun 29 14:40:50 2011 +0200" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Thu Jun 30 12:48:25 2011 -0400" }, "message": "xen/blkback: Add module alias for autoloading\n\nAdd xen-backend:vbd module alias to the xen-blkback module.
