The OneFS WebUI will be inaccessible if the webui_httpd.conf file under /var/run/apache2/ became stale on the problematic node: isilon-1# ps axuww | grep httpd | grep -v grep root 43633 0.0 0.5 170644 10188 - Ss 2:49PM 0:00.06 /usr/local/apache2/bin/httpd -k start daemon 43634 0.0 0.5 170332 9840 - I 2:49PM 0:00.00 /usr/local/apache2/bin/httpd -k start daemon 43638 0.0 0.6 174360 11652 - I 2:49PM 0:00.00 /usr/local/apache2/bin/httpd -k start <<< the output is missing "/usr/local/apache2/bin/httpd -f /usr/local/apache2/conf/webui_httpd.conf -k start" thread. There should be 3 or more threads on each node Attempting to manually start httpd of isi_webui service would result in the following message: isilon-1# /usr/local/sbin/webui_httpd_ctl start httpd: Could not reliably determine the server's fully qualified domain name, using 27.27.27.102 for ServerName httpd (pid 72923) already running isilon-1# cat /var/apache2/run/webui_httpd.pid 72923
If a node is restarted unexpectedly or if the webui process is killed in certain ways, the pid files are left. When webui is restarted either via MCP or via a node reboot, webui may not start correctly, emitting the error: > httpd (pid 72923) already running (where 72923 was the pid of the previously-running webui daemon)
SSH to the problematic node with "root" account. Verify if webui_httpd.pid exists: # ls -l /var/apache2/run/webui_httpd.pid If it does, remove that .pid file with the below command: # cd /var/apache2/run/; rm -f webui_httpd.pid - Atte mpt to start httpd again with # /usr/local/sbin/webui_httpd_ctl start After following the steps above, the output should be similar to the below where there should be 3 or more httpd of webui threads: jv8004-1# ps axuww | grep "webui_httpd.conf" | grep -v grep root 3135 0.0 0.6 261704 13280 - Ss 4Apr18 0:18.62 /usr/local/apache2/bin/httpd -f /usr/local/apache2/conf/webui_httpd.conf -k start daemon 3140 0.0 0.6 261668 13268 - I@ 4Apr18 0:00.23 /usr/local/apache2/bin/httpd -f /usr/local/apache2/conf/webui_httpd.conf -k start daemon 3145 0.0 1.5 307568 30924 - I 4Apr18 0:10.58 /usr/local/apache2/bin/httpd -f /usr/local/apache2/conf/webui_httpd.conf -k start Try to log in to the web administration on problematic node after the above steps are taken.
