similar to: unable to write files bigger than 4GB over NFS

hi, guys: Today when i typed "mount " command on the server and found this message: .. ... 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs (

Peter, we found that nfs over udp will corrupt data under very extrem load, there is no way to fix it due to the way how UDP works. TCP will not have these problems. I also wonder why the package size is only 1k. Everyone who wishes a slow connection can pass the desired options via the kernel cmdline. Everyone else prefers probably the fast mount. The defaults should look more like that: ---

Hello. We have a number of Xen 3.4.2. boxes which have constant iowaits at around 10% with spikes up to 100% when accessing data over NFS. We have been unable to nail down the issue. Any advice? System info: release : 2.6.18-194.3.1.el5xen version : #1 SMP Thu May 13 13:49:53 EDT 2010 machine : x86_64 nr_cpus : 16 nr_nodes

I''ve locked up my dom0 a couple of times this morning copying a 3GB file from local disk to an NFS mount(neither xend nor guests running). I don''t encounter this problem on the stock CentOS 4 kernel. The machine is a PowerEdge 2850 with 2 e1000 cards - the one in use is connected to a PowerConnect 2216 10/100 switch and has negotiated 100Mbit. I''ll check if the stock

I have been experimenting exporting btrfs subvolumes over nfs. Main subvolume is filesys1 mounted at /filesys1. Below this is subvolume base, user1 is in base and documents is in user1. documents is mounted at /documents. /etc/exports is: /filesys1/base/user1 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0) /filesys1/user1-snapshot 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0)

Hi all, I'm migrating from Gentoo to CentOS... I'm experiencing a rather low performance in NFS r/w (as client). NFS server is solaris (which exports zfs volumes via nfs). The very same exports were mounted with the same parameters (auto,nosuid,exec) on gentoo and centos server (bot x86_64)... It happens that centos is 5-10 times slower either in read and write operations... Ok,

Hello, Does anybody know how to avoid the file fragmentation when a file is created over NFSv3? A file created locally is OK: dd bs=32k if=/dev/zero of=test count=32x1024 conv=fsync filefrag test test: 10 extents found, perfection would be 9 extents When I create the file in the same dir, but from another machine, mounted over NFS: filefrag test test: 4833 extents found, perfection would be

I set up a 3.3 gluster volume for another sysadmin and he has added it to his cluster via automount. It seems to work initially but after some time (days) he is now regularly seeing this warning: "Too many levels of symbolic links" $ df: `/share/gl': Too many levels of symbolic links when he tries to traverse the mounted filesystems. I've been using gluster with static mounts

This seems like another basic question because I always assumed that if I threw something in my /etc/fstab then it will be automatically mounted at boot time (unless I put in the 'noauto' option). But my NFS partition isn't getting mounted, here's the excerpt from my /etc/fstab file, split on the whitespace so it's easier to read: nfs_server:/exports/var/www /var/www nfs

Hi, I've got another one... NFS error 101 with NFSROOT has been discussed a lot, and hpa gave an answer to it which appears right. It's ENETUNREACH, and I suspect my diskless box does not set its IP parameters right. PXElinux is set up as follows: label linvdr kernel kernel-linvdr append initrd=initrd-linvdr acpi=off root=/dev/nfs \

Hello, I''m a new user to Xen, so please be patient with me. I just installed a dom0 on my root-server and I also got a xenU to work with routed network. I can access from both sides and I can access both machines from any other computer too. So far - so good.. (gentoo on both ends by the way) My plan was to use a mounted NFS-directory from dom0 on my domU to place /home (and later

The number of threads has nothing to do with the number of cores on the machine. It depends on the I/O, network speed, type of workload etc. We usually start with 32 threads and increase if necessary. You can check the statistics with: watch 'cat /proc/net/rpc/nfsd | grep th? Or you can check on the client nfsstat -rc Client rpc stats: calls retrans authrefrsh 1326777974 0

Greetings all- I have a CentOS 5 (Final) system that is serving up content to several other hosts via NFS. The amount of data transferred is rather small as most of the files are under 100kb and each export has maybe 100 files that are accessed regularly. I'm finding that as I add more hosts accessing the NFS server, the performance seems to be getting poorer. There are obvious delays when

Hi I use rsync for daily backups from a mailserver. Every day the mailserver pushes backup to the backupserver. Cron runs the command: rsync -q -zrlpt --specials --chmod=Du+rwx \ --rsh 'ssh -F /root/ssh/config -i /root/ssh/private.key -o UserKnownHostsFile=/root/ssh/known_hosts' \ --files-from=/root/include \ --exclude-from=/root/exclude \ --link-dest=../previous \ /

Hi, I was hoping someone would have an idea of what's going on here... We have two NFS issues. One of which is certainly centos based, one of which we're not sure of. First issue is: As of Centos 5, we can't make simultaneous access to a directory via NFS. To duplicate, I cd into a share in two windows, copy a 1G file in the first window, and just do an ls in the other. The ls

Hello all, I have observed a problem with a diskless PXE client I am attempting to configure. PXE/NFS/DHCP/TFTPd server is running CentOS5.1 and the Diskless workstation's root and kernel was extracted from a CentOS5.1 (custom kernel due to setting to enable Root File System support). Problem: When the diskless client boots and logs in I notice that my root user is being squashed, even if I

Well, apparently there WAS a change on the Windows Server, which only affected new samba versions I was able to fix my issue by using this patch: https://bugzilla.samba.org/show_bug.cgi?id=12776 Can this be officially fixed please? >-----Original Message----- >From: Lange Norbert >Sent: Dienstag, 08.
