What distribution and why?

We¹re looking at the costs and effort of converting our installation from SuSE SLES to RedHat RHEL on the zSeries, and I¹m wondering what others are running, and why they chose the particular distribution. All comments are welcome, on or off list; I just want to be sure we¹re not backing ourselves

Nfs and pcnfsd daemon

Hi, On a Linux 2.6 kernel (I'm using RHEL 5), how is the pcnfsd daemon started? I have an SFS fiespace mounted via NFS on a zLinux guest and cannot write to it. IBM has looked at traces and says that no PCNFS operation is being sent to the VM server (VMNFS on another LPAR). The problem is on the N

SWAPGEN EXEC - doesn't like things in the stack

2008-04-10 Thread Scott Rohling
Wasn't sure how to best report an issue with SWAPGEN -- but here it is: Due to a Linux guest being autologged with a parm passed, the PROFILE EXEC which calls SWAPGEN twice to create 2 VDSKs had something in the stack. This caused the first invocation of SWAPGEN to fail (I believe because SWAPGEN

We run RHEL on z because that is what we run on Intel. It was easier for our Linux admins to know just one distro, and we can reuse a lot of the same processes and Red Hat features across the platforms. Sometimes it bites us when certain product vendors only support Suse on z, or when there is

Same here .. I consult with many customers who have RH on Intel and it makes sense to use the same distro on z. There have been a couple of occasions where SuSE was perhaps a little ahead on device drivers (FCP/SAN comes to mind) -- but in general RH is a solid distro. I also personally prefer

Hi, Scott. Thanks for this report of a bug in SWAPGEN. I guess I'm the unofficial SWAPGEN maintainer, so I'll incorporate your suggested fix into the current SWAPGEN release, and do some testing. I'll send a note to list when th new version is available, as well as sending it to a couple of other

One thing that NFS does very well is recover from server failures. All other file sharing protocols that I have seen tend to cause all the clients to fail when the server fails. This feature is the main reason that NFS prevailed over other methods. Recovering from a server failure was importa
