Hello, We are having performance problems trying to migrate our pop/imap servers to a new version. Our old servers are 4 debian lenny with 5GB of RAM running of XenServer VMs with kernel 2.6.32-4-amd64 and dovecot 1.1.16. New servers are 4 ubuntu 12.04 with dovecot 2.1.5 running on vmware vm with 6 cores and 16GB of RAM and kernel 3.2.0-24-generic. On both server we are using nfs 3 with

Hello, I set up NFSv4 server. To make sure I set vfs.nfsd.server_min_nfsvers=4. I can check its version, for example, by tcpduming and then I can see in wireshark lines like: Network File System Program Version: 4 V4 Procedure: COMPOUND.... .... is there any easier way to check its version? I see there is nfsstat -e option which shows delegs and locks. But all other ones are combined with nfsv3

We are occasionally experiencing trouble where the NFS server's load will shoot over 60+. (Normal of sub 1.0). I have been hunting this for a while, and I believe it comes down to "deliver". System setup: NFS servers: x4540 Solaris 10 x64 ZFS over NFS. NFS clients: Solaris 10 x64 postfix-2.4.1 with dovecot-1.1.11 deliver. What appears to happen, when I check for nfsstat per

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 three ESXi servers (and these

Hallo, we are using samba V.3.0.2a on Linux 2.4.18 Previous Versions of samba showed the same effect. The linux-box has mounted nfs-shares from solaris SunOS 5.8 This nfs-connection is a WAN-connection, that has limited bandwidth(some Megabit/second). When connection is slow, then it happened often that saving a file to this share is disturbed. Sometime it simply hangs, sometime an error

Hi, I am new to Dtrace. I am trying to run nfsv3rwsnoop.d script found on nfsv3 provider wiki page. I received following error: # ./nfsv3rwsnoop.d dtrace: failed to compile script ./nfsv3rwsnoop.d: line 12: failed to grab process 3 Line 12 is "nfsv3:::op-read-start" To use nfsv3 provider, do I need to install some additional package? If so, what is the package called? The system

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i''m trying to use the nfsv3 provider on S10U6, with the following simple script: #! /usr/sbin/dtrace -s #pragma D option quiet nfsv3:::op-read-start { printf("%s\n", args[1]->noi_curpath); } however, when running it, i get the following error: dtrace: failed to compile script ./nfs2.d: line 5: failed to grab

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

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,

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 fileserver's filesystem is ext4. 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)

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''ve been playing with the fsstat provider lately. I''m curious why its gone undocumented and largely ignored (per google). I admit that I did experience some oddities with the data, so I''d also like to rule out whether or not it has problems which might have caused it to be left in quietly. benr.

I created a centos 7 docker container in which I want to mount a NFS share in. Said share is owned by user virtual with uid 1200. So I do some exporting (docker container is in 172.17.0.0/16): spindizzy> cat /etc/exports /export 10.0.0.0/24(ro,fsid=0,no_subtree_check,sync) 172.17.0.0/16(ro,fsid=0,no_subtree_check,sync) [...] /export/mail 172.17.0.0/16(rw,root_squash,no_subtree_check,sync)

Is there an equivalent command to nfsstat -m on Centos 3.4? On solaris it reports statistics for each NFS mounted file system i.e.: /mount/point from host:/some/path Flags: vers=3,proto=tcp,sec=sys,hard,intr,link,symlink,acl,rsize=32768,wsize=32768,retrans=5,timeo=50 Attr cache: acregmin=3,acregmax=60,acdirmin=30,acdirmax=60 On a related topic, how can I make a Centos3.4 nfs server

Now that Solaris 10 11/06 is available, I wanted to post the complete list of ZFS features and bug fixes that were included in that release. I''m also including the necessary patches for anyone wanting to get all the ZFS features and fixes via patches (NOTE: later patch revision may already be available): Solaris 10 Update 3 (11/06) Patches sparc Patches * 118833-36 SunOS 5.10:

Will the ability to import a destroyed ZFS pool and the fsstat command that''s part of the latest Solaris Express release (B38) make it into Solaris 10 Update-2 when it''s released in June/July??? Also has any decision been made yet what build Update-2 will be taken from to give an idea of what can be expected for ZFS??? This message posted from opensolaris.org

I watched the recent discussions of "issues" with an Eaton Ellipse UPS with some interest. I use the US version of that UPS, the Ellipse Pro 1500 in my case. I had not encountered many of the issues recounted in those discussions. The Login Failure message is not unique to that UPS as I have seen it with my Cyberpower units. The polling setting also had me wondering as I have never had
