CentOS 6.5: NFS Server Crashes With List_add Corruption Errors

Hi,

I’m running CentOS 6.5 as NFS server (v3 and v4) and exporting Ext4 and XFS filesystem.

After many months that all works fine today the server crash:

  • That page lists the workaround if you log in, but no “resolution” as yet. Although there are internal Bugzilla ID’s for both 5 and 6

    echo 0 >/proc/sys/fs/leases-enable

    Thanks, I have found more information about this:

    “To work around this issue, use NFSv3 instead of NFSv4. Alternatively, turn off support for leases by writing 0 to /proc/sys/fs/leases-enable
    (ideally on boot, before the nfs server is started). This change prevents NFSv4 delegations from being given out, restore correctness at the expense of some performance.”

    from https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/5.6_Technical_Notes/Known_Issues-kernel.html

    I will evaluate if use NFS3 only or apply the trick.

    Ciao

  • Allesio,

    Are these VM’s — did you move the /VM files/ respectively to backup location named as per VM? e.g.:
    /DB
    /CORE business Server
    /etc

    Because it looks like your PowerEdge system chocked and you may have to:

    A: get that back online, fire up the systems.. or B: replace C: restor/replace

    The errors are pretty obvious to me at first pass — and if I was there I could tell in 5 minutes what is ‘probably’ wrong.. but that’s my first pass at this.

    I hope you had some kind of failover/redundancy with the “appliance”

  • Hi Jeffrey,

    this PowerEdge has a replica of the data on another server.

    Do you believe it is a hardware problem and not software?

    What makes you think that?

    Thanks
