I also have problems mounting rw using NFS3, Gutsy client mounting from CentOS 5 NFS server.
fstab: scaleo:/filer/temp /mnt/scaleo/temp nfs rw 0 0 sudo mount -a, check /etc/mtab: scaleo:/filer/temp /mnt/scaleo/temp nfs rw,addr=<IP manually removed> 0 0 Can't write to /mnt/scaleo/temp, try checking with nfsstat -m: /mnt/scaleo/temp from scaleo:/filer/temp Flags: ro,vers=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=scaleo Note "Flags: ro", according to mtab it's rw. Tried the exact same setup from a CentOS client and it worked. Added nfsvers=2 to fstab: scaleo:/filer/temp /mnt/scaleo/temp nfs rw,nfsvers=2 0 0 Remounted, check mtab: scaleo:/filer/temp /mnt/scaleo/temp nfs rw,nfsvers=2,addr=<IP manually removed> 0 0 And nfsstat -m: /mnt/scaleo/temp from scaleo:/filer/temp Flags: rw,vers=2,rsize=8192,wsize=8192,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=scaleo Hey, now it's rw. Verified that I can write to the share, works. Looks like there is a problem with NFSv3 in the Gutsy NFS client. Tried manually mounting (skipping fstab), same result. -- NFSv3 in Gutsy maps uids wrongly https://bugs.launchpad.net/bugs/159557 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
