One of the steps\nis to set the device readonly. This did not work as planned, or indeed at \nall. After the first --readonly, all requests for the device report \n\"No such device or address\" until a reboot, though /proc/mdstat says the \ndevice is still there.\n\nThis bug is fixed by mainline commit 065e519e71b2c1f41936cce75b46b5ab34adb588,\nwhich is in mainline as of 4.12-rc1. The commit was also cc'd to stable, but \nupstream 4.10 is EOL, so that is the reason for the SRU request.\n\n\n== Fix ==\ncommit 065e519e71b2c1f41936cce75b46b5ab34adb588\nAuthor: NeilBrown <neilb@suse.com>\nDate: Thu Apr 6 11:16:33 2017 +0800\n\n md: MD_CLOSING needs to be cleared after called md_set_readonly or do_md_stop\n\n== Regression Potential ==\nThis commit was also cc'd to stable and accepted, so additional upstream review\nwas performed.\n\n== Test Case ==\nA test kernel was built with this patch and tested by the original bug reporter.\nThe bug reporter states the test kernel resolved the bug.\n\nNeilBrown (1):\n md: MD_CLOSING needs to be cleared after called md_set_readonly or\n do_md_stop\n\n drivers/md/md.c | 5 +++++\n 1 file changed, 5 insertions(+)" }
