vim /usr/lib/ocf/resource.d/heartbeat/Filesystem<br>===========================================<br><longdesc lang="en"><br>Resource script for Filesystem. It manages a Filesystem on a<br>shared storage medium. <br>
<br>The standard monitor operation of depth 0 (also known as probe)<br>checks if the filesystem is mounted. If you want deeper tests,<br>set OCF_CHECK_LEVEL to one of the following values:<br><br>10: read first 16 blocks of the device (raw read)<br>
<br>This doesn't exercise the filesystem at all, but the device on<br>which the filesystem lives. This is noop for non-block devices<br>such as NFS, SMBFS, or bind mounts.<br><br>20: test if a status file can be written and read<br>
<br>The status file must be writable by root. This is not always the<br>case with an NFS mount, as NFS exports usually have the<br>"root_squash" option set. In such a setup, you must either use<br>read-only monitoring (depth=10), export with "no_root_squash" on<br>
your NFS server, or grant world write permissions on the<br>directory where the status file is to be placed.<br></longdesc><br><shortdesc lang="en">Manages filesystem mounts</shortdesc><br>=======================================================<br>

<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Maybe this is a n00b issue, but I understand that monitor depth="20" in ocf:heartbeat:Filesystem is supposed to create a test file and check whether it can write to that file, and declare the resource failed if the filesystem goes read-only. The test file does not get created, and I can’t see where any errors might be being logged to. <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I’ve tested this configuration by disabling a switch port. The second node picks up the services correctly, but the first node keeps on running them too, and does not notice that it no longer has a writeable filesystem. If the port is reconnected, they both have the same ext3 filesystem mounted at once, which makes a fine mess.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Here’s my current configuration. Have I missed some vital detail? Should I be brining the iscsi connection into pacemaker too?<u></u><u></u></p><p class="MsoNormal">
