Thread: Clustered snapshots

    Default Clustered snapshots

    Hi All,

    I just want to know if Cluster Snapshot supported in ZRM v3.1? My remote MySQL server datadir is mounted in a cluster disk at /var/lib/mysql. If I do backup raw mode with LVM snapshot I got error messages. This is the verbose log {http://tinyurl.com/zmrvlog1}.

    Thanks.

    What type of cluster is this? Is it GFS?

    It is running in Red Hat Cluster Suite. Yes, it is GFS.

    Can you please email me(jacob@zmanda.com):

    /usr/share/mysql-zrm/plugins/lvm-snapshot.pl

    From the MySQL server. I will patch it to do the GFS freeze and unfreeze operations and you can try the backup again.

    Hi Jacob,

    My apology, it's not running in GFS. It's a normal clustered LVM shared disk mounted to the node where the mysql service is automatically running every time CLVM disk is mounted to the remote server.

    Do you still need my "/usr/share/mysql-zrm/plugins/lvm-snapshot.pl" ?

    Thanks.
    James
