XFS Filesystem Support in Veritas Cluster Server

Finally a blog post after more than 2 years!

I can't say I was too busy to update this but I was lazy

There is nothing much to say but I've been working for Huawei Technologies since last summer.

Ok, lets talk about the topic.

I was setting up several clusters recently and I formatted the storage using my favorite filesystem, XFS :) But the strange thing was that Veritas Cluster Server (We are using 4.1)was unable to mount the storage automatically! After reading the engine log file I found this error: “Unsupported filesystem!” wtf?

If you are an experienced linux user, you most probably know that the applications which run on linux are not dependent on the filesystem format, in other words you are free to use whatever filesystem you like. So my guess was that the guys at Symantec/Veritas Software don't like XFS.

As always I googled to find a solution but I failed to So my last change was to make VCS support my lovely filesystem. After greping for other supported filesystem names in /opt I found these configurations:

/opt/VRTSvcs/bin/Mount/functions.pl

my (@supported_fs) = ($default_fs, "ext2", "ext3", "nfs", "reiserfs");

/opt/VRTSvcs/bin/Mount/Mount.xml

            <attr_description>Type of file system.</attr_description>
            <possiblevalues>
                <value>vxfs</value>
                <value>ext2</value>
                <value>ext3</value>
                <value>nfs</value>
                <value>reiserfs</value>
            </possiblevalues>

So I edited both files to add “xfs”:

/opt/VRTSvcs/bin/Mount/functions.pl

my (@supported_fs) = ($default_fs, "ext2", "ext3", "nfs", "reiserfs", "xfs");

/opt/VRTSvcs/bin/Mount/Mount.xml

            <attr_description>Type of file system.</attr_description>
            <possiblevalues>
                <value>vxfs</value>
                <value>ext2</value>
                <value>ext3</value>
                <value>nfs</value>
                <value>reiserfs</value>
                <value>xfs</value>
            </possiblevalues>

Ta-da! Now everything works fine.

Don't forget to update these files on all cluster nodes in the group!

I'm not dead!, VCS, Veritas, Server, Cluster, XFS, Filesystem
