similar to: Using NFSv3 and NFSv4 at the same time with CentOS6

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

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, last day I tried to enable "nfsv4 delegation" on my cluster (enable nfsv4.0 and read delegation on Netapp and remount the volume on Linux Centos 6.7 clients with Dovecot+Director). It was a failure, after some minutes the load on clients was high, and in dovecot.log I found these errors (repeated continuously): Aug 17 20:28:17 pop01eeh dovecot: imap(info at domain.com): Error:

Hi Marco, You will hit muliple problems, most can be solved. Im installing a new member here with samba 4.8.5 and building new samba 4.8.6 atm. ;-). Im (trying to ) fix this also again in this new setup. Below it a bit of what i know. > Client are in DHCP, so it is hard to use 'normal' NFSv3 mount, eg > security by IP.

Hi, We are running into a problem with a Samba setup and would like 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

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

Hi, in this tipical setup (Dovecot/Director thate share Maildir via NFS) on your NFS Server you have (about) 90% of read operations and only 10% of write operations. If you see detailed stats for NFS operations you have 40-50% of GETATTR, this means that NFS/Dovecot clients are caching data (mainly dovecot index files) but they have to revalidate the cache frequently asking to the NFS

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

Howdy, I wrote a pair of scripts to measure file and NFSv3 operations, and thought I would share them with the folks on the list. You can view the script output by pointing your browser at the following URLs: Per Process NFSv3 Client statistics (inspired by fsstat/nfsstat): http://daemons.net/~matty/code/nfsclientstats.pl.txt Per Process File Operations (inspired by fsstat):

Hai, I'm getting somewhere, here you go, a snap of what i have atm. And what works atm. Im asuming you have winbind already running. Obligated is A+PTR record in the DNS. You can turn or the rdns check in krb5.conf but i did not test that. # Tested on Debian Stretch - NFSv4 SERVER apt-get install --auto-remove nfs-kernel-server systemctl stop nfs-* Added in krb5.conf below the

Hai, Hmm.. Bummer.. I just discovered the debian package dont have the vfs_nfs4acl include in the build. And because of that it's not in my packages. I'll have a look into it, see what i can make of it.

I will soon be implementing a Fedora Core 4 (or 5), 2.8MHz Xeon, 1GB RAM, 2.5TB storage, gigabit ethernet server which will hold backup copies of about 200 DVDs. These DVDs will be played through 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

just a quick update: no issues with NFSv4.0 (load is slowly growing, currently ~7k mailboxes) instead, bad news from delegation front, we enabled it for a couple of days but we ran in ugly issues: processes went in "uninterruptible sleep" state, load average gets huge, reboot was the only escape :-( -brd Alessio Cecchi wrote: > Il 12/06/2015 13:02, brd ha scritto: > >Alessio

I have a situation where I need to share, via Samba, a filesystem mounted via NFSv4. I'm struggling with the best way to make Samba see the NFSv4 ACLs and enumerate them to provide the proper SMB/CIFS access to the files, instead of "Access Denied" errors that I currently get. Looking at the Samba source, the only obvious NFSv4 stuff appears to be the following: - zfsacl, available
