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

I have many errors of this type in my logs: 2 * postfix/pipe[21511]: BC8DD3356A: to=<*****@******>, relay=dovecot, delay=1001, status=bounced (Command time limit exceeded: "/usr/local/dovecot-1.0-rc2/libexec/dovecot/deliver") My command time limit is 1000s in postfix (more than 15 minutes) After many check, I found that a lots of this error is not really an error. The mail is

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):

I found this from ocfs1.4 document: g) NFS OCFS2 volumes can be exported as NFS volumes. This support is limited to NFS version 3, which translates to Linux kernel version 2.4 or later. Users must mount the NFS volumes on the clients using the nordirplus mount option. This disables the READDIRPLUS RPC call to workaround a bug in NFSD, detailed in the following link:

Hi Barbara, Thanks for all these suggestions. Yes, jumbo frames are activated and I have only two 10Gb ethernet switch between the server and the client, connected with a monomode fiber. I saw yesterday that the client showing the problem had not the right MTU (1500 instead of 9000). I don't know why. I changed the MTU to 9000 yesterday and I'm looking at the logs now to see if the

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

Hello, I have an interesting architecture consisting of a 3 RHEL 5.3 NFS nodes that mounts about 30 TB worth of iscsi disk and presents them as 6 different NFS shares. It is an active-active-active cluster with each node presenting a couple of shares. It works pretty well. I am doubting my decision to use NFS and am wondering if CIFS would be a better route. Here are the NFS stats: getattr

Hi folks, I just saw one of my FreeBSD servers (7.0-stable of June 2008) crash while trying to access the .zfs snapshot directory via a nfs client machine. The server got a page fault caused by the nfsd process. It wasn't even able to dump the kernel image anymore. Resetting the machine it first appeared to come back fine, but shortly before the login prompt the nfsd let it crash hard again

All, This is a heads up only for users exporting OCFS2 volumes as NFS mounts. If not, please disregard this email. Recently there was a bugzilla filed that mentioned observing file system lockups when accessing OCFS2 exported volumes with FreeBSD NFS clients. The lockups were not observed by him with Linux NFS clients. http://oss.oracle.com/bugzilla/show_bug.cgi?id=977 Analysis showed that the

Ok, starting to make sense now. In order to fix it.... I note that the lower level calls are wrapped in dir.c - eg dptr_SeekDir(...) wraps SeekDir(...) this might allow for some code to use array indexes instead of NFS cookies as noted by Chris Chilvers here for the 3.10 kernel: https://lore.kernel.org/all/CAAmbk-e-YQAPo6QyNB0aJyc9qzUShmEC+x5eTR7wqp1ABWADsg at mail.gmail.com/T/ > On 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.

Hi In QEMU 8 virtiofsd has been removed in favor of the rust version. Which includes options that are not longer supported, Do you have a view on what should be used going forwards to support virtiofsd in libvirt with qemu 8? The options are showing as depreciated, -o <compat-options>... Options in a format compatible with the legacy implementation [deprecated] Rust

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

Thanks for a great file system! I have a two-node cluster working as a HA NFS server. This system has worked fine for almost a year, but recently I found that an ocfs2 file system had been corrupted and needed to be repaired with fsck.ocfs2. Even though I don't think that any data was lost I found that 4 of my 14 ocfs2 partitions had some errors which were corrected by fsck.ocfs2. I then

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

Hi all, I have been a loyal user of SAMBA since about 1996(?), and I recently upgraded a RH linux based system from by skipping a few generations and going directly from rh9 to FC5. Mostly everything is working, but there is an issue I haven't worked out yet with SAMBA. The main server here in our group has several shares, including some that are mounted from other servers via nfs,
