    I'm having problem with DNS clustering, it seems that the second server didn't copied all db file from main server as on /var/named on second server is empty.

    here is the detail of both server:

    Server A:
    Centos 4.4
    WHM 11.2.0 cPanel 11.6.0-R15076

    Server B:
    Centos 5
    WHM 11.2.0 cPanel 11.6.0-R15076

    Server A is the main server and has accounts in it, I then setup server B (fresh install) and setup DNS cluster.

    I setup on both (A & B) DNS clustering with DNS Role set to "Synchronize Change" now if I edit/view the DNS zone via "Edit DNS Zone" on DNS Function menu, it seems that the record is modified on both server.

    the problem is when i restart bind on server B, i got this error message:

    named[1462]: could not open entropy source /dev/random: file not found 
    named[1462]: client view localhost_resolver: received notify for zone '': not authoritative
    I know that /dev/random is not on the server, how to install or create this /dev/random?
    why the second server (server B) gives not authorative error messages?

    when i test on i got FAIL error on these tests:

    Lame nameservers : ERROR: You have one or more lame nameservers. These are nameservers that do NOT answer authoritatively for your domain. This is bad; for example, these nameservers may never get updated. The following nameservers are lame:
    <[I]showing IPs of Server B[/I]>

    Missing nameservers 2 : ERROR: One or more of the nameservers listed at the parent servers are not listed as NS records at your nameservers. The problem NS records are:
    <[I]showing nameservers of Server B[/I]>
    Does all DB files on /var/named of main server (server A) should be copied to /var/named of second server (server B) or not?
