Bonding

2006-02-14 Thread Johnny Tan
Hi All, Recently, I have tried to do network teaming for two network cards to perform as one network for HA purpose. I found that SLES 8 includes bonding drivers. It works fine for SLES 8 on Intel. However, I encountered problem with SLES 8 on S390. Has anyone tried using bonding on SLES 8

NFS hangs

Hello, We have a filesystem which is shared by 4 Linux guests via NFS. We have been using this setup for quite some time. Recently we've seen 2 cases where access to the NFS file on 1 or more of the non-owning guests began to slow down. A df command on the effected system would stop before

Some questions: - What other changes have taken place on the VM system? - How big are the virtual machines? - Do other commands on the affected Linux guests respond quickly (what about on the NFS server(s))? - How much storage does your VM system have? - What are the SRM settings for your VM

Neale, - No changes have been made to z/VM. - These are 1G WebSphere guests, each with 768MB java heap size. - All other commands work fine on all 4 servers. Only commands going against the NFS, e.g. df, ls, on the effected system(s) run slowly until that system is bounced. - z/VM has 17GB

Alan, I will try those commands the next time we see the problem. The df and ls commands against the NFS do eventually return, after 10 to 20 seconds, so data is actually moving, albeit slowly. Thanks, Hank -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf

John, - Here is contents of /etc/exports on the system running the NFS server: /xs2files 192.168.47.72(rw,sync,no_root_squash) - The lock and portmap daemons appear to be running on the effected system(s). - I don't see any .nfs* files in the filesystem. - The files are mounted rw as you can

We used to experience something similar to this. A mount appears to hung but eventually succeeds after a long time. We then run portmap service on all the clients and the problem went away. I never realy fully understood why this solved the problem. -Original Message- From: Linux on

Hi David, I am using SLES 8 SP4. OSA is attached to z/VM 4.4 and z/VM assigned three device numbers to linux guest to form on NIC. If there is qetharp for ARP equivalent on zLinux, is there any other network teaming software that is equivalent with bonding? qethbonding? Cheers. --
