  • GFS2 Mounting Issues

    Posted on

    Hello,

    I'm running into issues trying to mount my newely created GFS2 partition that resides on our SAN. We have a 2 node cluster configured.
    Here are the steps I took into creating and trying to mount the GFS2 partition;

    pvcreate /dev/sdb
    vgcreate -c n LinuxCluster /dev/sdb
    lvcreate -L 1G LinuxCluster
    lvcreate -L 9.99T LinuxCluster
    mkfs.gfs2 -j 2 -p lock_dlm -t Linux-Cluster:ExportCluster /dev/LinuxCluster/lvol1
    mkfs.gfs2 -j 2 -p lock_dlm -t Linux-Cluster:CTDB /dev/LinuxCluster/lvol0

    when I try to do the following command to mount it the command just hangs and does nothing until I kill it.

    mount.gfs2 -o noatime /dev/mapper/LinuxCluster-1vol1 /export

    When I do an strace on it I get the following information;

    execve("/sbin/mount.gfs2", ["mount.gfs2", "-o", "noatime", "/dev/mapper/LinuxCluster-lvol1", "/export"], [/* 34 vars */]) = 0

    If there is anymore information I can give please let me know.

    Thanks.
