Hi all, I have two centos6.2 servers acting as a nfs servers (nfsv3 for now). Due to some security requeriments, I need to share some folders using nfsv4 (with kerberos auth), but I have a doubt. Is it possible to serve shared folters using nfsv3 and nfsv4 (with kerberos auth) at the same time in the same server with centos6?? Nfsv3 is used to serve storage for t...

Does anyone, is anyone running Xen on NFSv3 successfully? What are some of your pain points/success points? Have you tried a clustered file system with better results such as DRBD or GFS?

We recently had a strange NFS performance anomaly between a V880 running snv_124 and two NetApp filers. To investigate, a DTrace NFSv4 (and eventually NFSv3) client provider would been extremely helpful. Unfortunately, all I could find were a request for code review of a v3 client provider and another request for help developing a v4 provider. Nothing seems to have come from those initiatives, though. Any updates? Thanks. Rainer -------------------...

Yes, this sounds like the correct explanation! Our RHEL5.6 PXE/TFTP/NFS server is certainly configured for NFSv3. I haven't explored the NFSv4 approach though. How can we tweak the CentOS6 Kickstart installation to explicitly request an NFSv3 service in the PXE config file: kernel CentOS-6-i386/vmlinuz append load_ramdisk=1 initrd=CentOS-6-i386/initrd.img network ks=nfs:130.226.86.4:/u/rpm/k...

I have several CentOS 5.2 workstations in a Sun Solaris NIS domain and Solaris NFS servers (all Solaris 8). Frequently the auto mounter hangs with very high utilization -- I think it might be due to the Solaris 8 servers only using NFSv3 and the CentOS wanting to use NFSv4. How can I set the system to use NFSv3 globally, even for auto mount maps from my ancient Solaris NIS domain (which I wold like to upgrade, but that's another story...) -------------- next part -------------- An HTML attachment was scrubbed...

...a gigabit LAN to another Fedora Core 4 (or 5) workstation using xine which will then output video to the projector in my living room. I am not asking to start a competition or war on the list. My question is, which is "cheaper" both in terms of processing power and network overhead: nfsv3 or smbfs or cifs? I'll also take information on nfsv4, though that is not my current setup. I use Samba for tons of Linux <--> Windows things, but since this is a Linux <--> Linux thing, I wasn't sure which way to go in order to minimize the use of the new processor and min...

When somebody is hammering on the system, I want to be able to detect who''s doing it, and hopefully even what they''re doing. I can''t seem to find any way to do that. Any suggestions? Everything I can find ... iostat, nfsstat, etc ... AFAIK, just show me performance statistics and so forth. I''m looking for something more granular. Either *who* the

I see there is nfsstat -e option which shows delegs and locks.

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a time (even deliveries are managed...

Hi everybody and thanks to those persons who make klibc being possible. I am booting a lessdisks system from a server. I have got it in NFSv3 but I would like use the features of NFSv4. I am using initramfs-tools so I have in my initrd.img the utility nfsmount wich make possible booting in NFSv3. I would like know if exists some version of nfsmount or some patch or, if does not, some program (a small one) I could use instead it to boot i...

Hello, I'm using rsync 3.0.9 to backup several NFS shares from a fileserver, mounted over NFSv3, to a local RAID on a backup server. Both servers are running Ubuntu 12.04 server LTS.

The NFS shares are mounted on the backup server as follows: fileserver:/mnt/storage/share1 /mnt/share1 type nfs (ro,tcp,bg,soft,intr,addr=192.168.1.1) fileserver:/mnt/stor...

...to know if a current fix or workaround is at all possible. Our setup is a NetApp filer serving NFS v4 that is mounted by Solaris and Linux servers. On those servers we are using Samba to create shares of those NFSv4 mounted filesystems. We are migrating to this NFSv4 setup from an existing Solaris NFSv3+Posix ACL setup that also had Samba shares on top of the NFSv3+ACL mounts. In our setup, we are relying on NFSv4 ACL inheritance. Here's an example of an ACL on a file (as created by a touch command): root at system # ls -lVd test_sneppef.txt -rw-r--r--+ 1 root root 0 Mar 6 13...
