After reinserting the disk, I enabled additional Analytics to get a good trace of the effect &#8211; but it wasn&#8217;t reproducing. I was trying to figure out why, and wondering how close the disk was to the vibration point &#8211; when I shouted at it to give it some extra vibration. This worked better than expected, and caused issues in all the disks I was shouting at, not just the missing screw one. I was using the Analytics by-disk breakdown to map where I was shouting at (although in the video I shouted a bit too loud, and vibrated most disks in both JBODs). If I can get the missing screw issue to reproduce, I&#8217;ll post a blog entry with the screenshots.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Brendan Gregg \u043e\u0442 <a href=\"http:\/\/blogs.sun.com\/fishworks\/\">FISHworks<\/a> \u0435\u043a\u0438\u043f\u0430 \u043d\u0430 \u0421\u044a\u043d \u043f\u043e\u043a\u0430\u0437\u0432\u0430 \u043a\u043e\u043b\u043a\u043e \u043b\u043e\u0448\u043e \u0435 \u0447\u043e\u0432\u0435\u043a \u0434\u0430 \u043a\u0440\u0435\u0449\u0438 \u043d\u0430 storage-\u0430 \u0441\u0438:<\/p>\n<p><em>\u0442\u0443\u043a \u0438\u043c\u0430 \u0432\u0438\u0434\u0435\u043e<\/em><\/p>\n<p>\u0414\u043e \u0442\u0430\u043a\u0438\u0432\u0430 \u0432\u0430\u0436\u043d\u0438 \u043e\u0442\u043a\u0440\u0438\u0442\u0438\u044f \u0441\u0442\u0438\u0433\u0430 \u0447\u043e\u0432\u0435\u043a \u043a\u043e\u0433\u0430\u0442\u043e \u0438\u043c\u0430 \u0442\u0432\u044a\u0440\u0434\u0435 \u043c\u043d\u043e\u0433\u043e \u0442\u0435\u0445\u043d\u0438\u043a\u0430 \u0438 \u043f\u043e\u043d\u0435 \u043c\u0430\u043b\u043a\u043e \u0441\u0432\u043e\u0431\u043e\u0434\u043d\u043e \u0432\u0440\u0435\u043c\u0435. \u0417\u0430\u043c\u0438\u0441\u043b\u044f\u043c \u0441\u0435 \u043a\u0430\u043a \u043b\u0438 \u0441\u0435 \u0435 \u0441\u0442\u0438\u0433\u043d\u0430\u043b\u043e \u0434\u043e \u0437\u0430\u0431\u0435\u043b\u044f\u0437\u0432\u0430\u043d\u0435\u0442\u043e \u043d\u0430 \u0442\u043e\u0437\u0438 \u0435\u0444\u0435\u043a\u0442? \u041a\u0430\u043a\u0432\u043e \u043b\u0438 \u0441\u0430 \u043f\u0440\u0430\u0432\u0438\u043b\u0438 \u0438\u0437\u043d\u0443\u0440\u0435\u043d\u0438\u0442\u0435 \u0438\u043d\u0436\u0435\u043d\u0435\u0440\u0438 \u043e\u0442 FISHworks \u0437\u0430 \u0434\u0430 \u0441\u0435 \u043f\u0440\u043e\u044f\u0432\u0438?<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[],"tags":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"http:\/\/blog.yavor.info\/index.php?rest_route=\/wp\/v2\/posts\/300"}],"collection":[{"href":"http:\/\/blog.yavor.info\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/blog.yavor.info\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/blog.yavor.info\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/blog.yavor.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=300"}],"version-history":[{"count":0,"href":"http:\/\/blog.yavor.info\/index.php?rest_route=\/wp\/v2\/posts\/300\/revisions"}],"wp:attachment":[{"href":"http:\/\/blog.yavor.info\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=300"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/blog.yavor.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=300"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/blog.yavor.info\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
