hey list! I am attempting to shore up some centos machines (ranging from centos 5 to centos 5.4) for pci compliance by changing the port that nlockdmgr listens on to function under a privileged port. So what I did was try to hardcode the port by editing /etc/sysconfig/nfs # TCP port rpc.lockd should listen on. LOCKD_TCPPORT=1011 # UDP port rpc.lockd should listen on. LOCKD_UDPPORT=1011 #

Hi all, I have setup a CentOS6.3 x86_64 host to act as a nfs server. According to RHEL6 docs, portmap is not needed when you use NFSv4, but in my host I need to start rpcbind service to make NFSv4 works. My /etc/sysconfig/nfs # # Define which protocol versions mountd # will advertise. The values are "no" or "yes" # with yes being the default MOUNTD_NFS_V2="no"

Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to

Hi everyone, I got the error: NET4: Unix domain sockets 1.0/smp for linux NET4.0 ds: no socket drivers loaded request_module[block-major-8]: root fs not mounted VFS: Cannot open root device ""or 08:03 Please append a correct "root"boot option The strange thing is that it tries to mount from harddisk.

I have been googling and searching the archive , haven''t got anything helpful. Would appreciate any help. Got the follow error when trying to start a domain using NFS root IP-Config: Incomplete network configuration information.

After getting a reasonably configured NFS4 setup working on my Scientific Linux server, I spent a majority of my evening trying to do the same with my Centos 5 box, with fruitless results. Most attempts to mount that server returns the following message: [root at sl01 log]# mount -t nfs4 192.168.15.200:/opt/company_data /mnt mount.nfs4: Operation not permitted As nearest as I can tell, I was

Hi This is a PXELinux problem that I'm facing. The problem, in brief, is that I have a set of diskless nodes (AMD Athlon XP 1800+ with 256MB RAM) connected via an internal 172.20.0.0/24 network to a dual AMD Opteron running SuSE Linux 8.3 for AMD64. I want the remote machines to diskless boot off the main server and run independently. The diskless machines have a PXE-compliant BIOS for

Hi all, I'm extremely puzzled by the behaviour of one of my Samba servers. It's been working fine for yonks, and this morning (abuout 11:32) it just stopped. (mostly) Connecting to shares still works. Navigating the tree till works. Changing (DOS) attributes still works. But actually opening files and reading the contents doesn't work. The client just times out (Win 3.11, and

Hi All, I'm having an issue with connecting Gluster with NFS. When I do gluster volume status. It shows the ports aren't opened. NFS Server on localhost N/A N/A N N/A the /var/log/glusterfs/etc-glusterfs-glusterd.vol.log file states this: [2017-07-10 15:48:25.214618] I [MSGID: 106006] [glusterd-svc-mgmt.c:323:glusterd _svc_common_rpc_notify]

Hi, I am trying to mount the windows NT share to solaris 8.0 using Redhat 8.0 nfs. Using smbmount I mounted windows share in Linux as /home/percipia/smb. I setup Linux as NFS Server and exported /home as nfs export. [root@ldap root]# cat /etc/exports /home 192.168.1.0/255.255.255.0(ro,nohide,insecure,sync) [root@ldap root]# rpcinfo -p program vers proto port 100000 2 tcp 111

CentOS 5 updated, Xen host. The portmap on this machine is somehow "stuck" and I can't figure out why. I enabled it to be able to mount a remote nfs share. The first hurdle was that "portmap" didn't appear in the chkconfig list, it was installed with the initial packages but not added to chkconfig. Took me a while to figure this out. Adding and starting it up is no

Hi, I'm resending since I got no feedback: I assume that the message was lost... The attached patch fixes a few bugs related to the spoofing portmapper used by nfsmount.

Hi folks, I've followed a set of instructions I found on http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise_linux_sysadmin_guide/ch-diskless.htmli which describes using system-config-netboot to set up PXE booting. I used a CentOS-4.3 install (custom, all options de-selected, then anaconda-busybox installed after the fact) as a reference/base. I followed the

I'm trying to boot RedHat 9.0 on a diskless PC from a head machine running Redhat 9.0. The network appears to be setup correctly. I can boot the installation disk image fine using pxelinux. What I am trying to setup is a number of different Linux systems each with its own root directory on the head machine. I am hoping that I don't have to modify the kernel for any of these systems.

Using Centos 5.2 upgraded from 5.0 using yum on a couple of old Dells in a lab environment. I don't think hardware is part of the problem, just need configuration help. 1: I can boot the diskless client and it come up, but when I do a "mount" command on the client, the output is indistinguishable from the output of the mount command on the server. Currently the fstab in

Im trying to get a diskless boot set up under CentOS 5.2, and having no luck at all. I am to the point of running system-config-netboot, and whatever information I put in, I get an error message. Responding to the 2nd button on the first popup, which asks for NFS info, I put in the IP address of the current machine (the machine that will hold the boot images for the diskless machine) and the

Does anyone have any good how-to's or documentation on setting up read only root NFS for pxe booting diskless computers? A few months ago I stumbled upon an official Redhat doc through a google search(not hosted by redhat and I cannot find it anywhere on the Redhat site) written by Dave Kline named "Configuring diskless clients with Red Hat Enterprise Linux" from 2011. It seemed to

Hi, I am working on the diskless booting over Infiniband networks. At the moment we have created and implemented architecture which allow diskless booting of Linux nodes on x86, x86_64 and Itanium platforms. The system works by booting first small custom made Linux kernel of the Infiniband adapter ROM. The kernel has enough of infiniband stack to setup TCP/IP networking over infiniband. Then it

For some time now I have been puzzled as to why certain portions of my system boot were quite slow -- but only after journal recoveries. I was fearing that there was some ugly interaction between the recovery and the use of the journal shortly afterward but alas that is not the case. So just in case anybody else is seeing this problem and decides to try to hunt it down, let me save you some
