similar to: nfs vs. cifs based on my usage profile

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Time for another cifs-utils release! Nothing terribly earth shattering here. Some distros (like Fedora) are moving krb5 credcaches out of /tmp by default. Users of these distros will definitely want to upgrade. Highlights: * Fixes for mounting with '/' in usernames with sec=krb5 * Support for DIR: type krb5 ccaches * support for

Hi Aurélien, Thanks for the idea! For Debian packages: 6.4-1 works 6.5-1 works 6.5-2 works 6.6-1 fails 6.6-5 fails So looks like something changed from 6.5 to 6.6... When I have time I'll figure out how to compile the upcall binary.

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:

Apologies for v3 series, I had some extra patches in there. This is the one that should have been sent. Relabeled as v4 for clarity. Third respin of this series. Reordered for better safety for bisecting. The environment scraping is now on by default, but can be disabled with "-E" in environments where it's not needed. Also, I've added a patch to make cifs.upcall drop

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

Chad reported that he was seeing a regression in cifs-utils-6.6. Prior to that, cifs.upcall was able to find credcaches in non-default FILE: locations, but with the rework of that code, that ability was lost. Unfortunately, the krb5 library design doesn't really take into account the fact that we might need to find a credcache in a process that isn't descended from the session. When the

hi! One of our user removed a directory through samba and right after that recreated it. It looks like this now: ?????????? ? ? ? ? ? 20110817 Gluster version is 3.2.2-1ubuntu~ppa1~lucid1 on client (samba server) and the same but Natty on the nodes. It was upgraded from 3.2.1. What is this? If a client try to access it, it freezes up. This is in log: [2011-08-17

I'm running Debian/Squeeze on an AMD64 system. For some reason they have recently stopped shipping mount.cifs with the setuid bit set. Now it appears that they have changed the internal settings to prevent it from running setuid. This means that I can't define the share in fstab with "user" and connect from my Linux user account. Mounting smb/cifs shares seems to be blocked

Third respin of this series. Reordered for better safety for bisecting. The environment scraping is now on by default, but can be disabled with "-E" in environments where it's not needed. Also, I've added a patch to make cifs.upcall drop capabilities before doing most of its work. This may help reduce the attack surface of the program. Jeff Layton (4): cifs.upcall: convert

Hi: I have been using Dovecot for well over a year now and it has always worked with few problems. The mail setup is not simple... Postfix+MailScanner+ClamAV+Docvecot+MySql+postfix.admin... just to mention the major things. The system is CentOS 5.3 on VMware. The maildir is on an NFS share, index and control is local. About a month ago I thought I upgraded from 1.1.x to 1.2.x. by doing an

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

Hello CentOS / RedHat / IBM folks! I am wondering if I can get a communication channel opened with someone who can affect changes win upstream RHEL? I don't have support accounts with RHEL, and use CentOS almost exclusively. I did have a direct email conversation with Mr. Daniel Walsh regarding these problems, but his answer was to create custom policy to allow what's being denied, as

Small respin of the patches that I posted a few days ago. The main difference is the reordering of the series to make it do the group and grouplist manipulation first, and then the patch that makes it grab the KRB5CCNAME from the initiating process. I think the code is sound, my main question is whether we really need the command-line switch for this. Should this just be the default mode of
