We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options:

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?

Hi, I had to review a samba setup recently where people experienced strange things. Basically they more from a solaris on phisical machines environment (locally hosted) running an old version of samba (2.x or even 1.x) to a Red Hat virtualized environement runing 3.6 (remotely hosted). The link between clients and server is really good (2x100Mb/s fiber) and browsing shares and opening office

We had someone from Oracle support move one of the database control files on an OCFS2 volume that's not mounted with datavolume,nointr (he moved it to /opt/oracle). At that time I didn't realize the problem. We'll move the control file to a volume that's mounted with datavolume,nointr options. The question is: how bad is it? We are experiencing some serious problems,

Upon system boot, is it ok to mount OCFS2 mounts from /etc/rc.local rather than /etc/fstab ? Are there any downsides to using rc.local that you are aware of? Example /etc/rc.local script: #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff.

Hi, I have added heartbeat mode as global, but when I do a mkfs and mount, and then check the mount, it says I am in local mode. Even /sys/kernel/config/cluster/ocfs2/heartbeat/mode says local. I am running CentOS with 3.x kernel, with ocfs2-tools-1.6.4-1118. mkfs -t ocfs2 -b 4K -C 1M -N 16 --cluster-stack=o2cb /dev/sdb mount -t ocfs2 /dev/sdb /mnt -o

The in-kernel nfsroot code is obsoleted by kinit. Remove it; it causes conflicts. Signed-off-by: H.

Background: I'm new to dovecot (although with many years Washington IMAP behind me). We're considering migrating from Washington IMAP to dovecot on the main service here, and have just started trying dovecot, using RC7. Washington, IMAP has the usual(-ish) "/var/spool/mail" shared area for the INBOX (trad. UNIX "From " format); a user's folders default to being

Hi, Our dovecot setup consists of two hosts running dovecot-1.0.beta9 with Maildir/indices stored on NFS(noac,actimeo=0 used). I am seeing these messages at times - but no real problems on the client side. Is this something to worry about? dovecot: Oct 17 10:33:31 Error: IMAP(user): Corrupted index cache file mailstore/user/Maildir/.mail.incoming/dovecot.index.cache: invalid record size

Greetings - I'm now in the last couple of weeks before going live with Dovecot (v1.0.3) on our revamped IMAP service. I'd like to double-check about the best mount options to use; could someone advise, please? I have three separate directory trees for the message store, the control files and the index files. These are arranged as follows: Message Store Mounted over NFS from

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

Afternoon, We have an ocfs2 release 1.4 filesystem shared between two nodes (RHEL5). The filesystem in question is used exclusively for Oracle RMAN backups.

Hi Timo, We've been running Dovecot with Maildir on NFS for quite a while - since back in the 1.0 days I believe. I'm somewhat new here. Anyway... The Wiki article on NFS states that 1.1 and newer will flush attribute caches if necessary with mail_nfs_storage=yes. We're running 1.2.8 with that set, as well as mail_nfs_index=yes, mmap_disable=yes and fsync_disable=no. We have a pool

Hello. We've started a virtualisation project and got stuck in one moment. Currently we are using the following: Intel 2312WPQJR as a node Intel R2312GL4GS as a storage with Intel Infiniband 2 ports controller Infiniband Mellanox SwitchX IS5023 for commutation. The nodes run CentOS 6.5 with built-in Infiniband package (Linux v0002 2.6.32-431.el6.x86_64), the storage - CentOS 6.4 also built-in

I would like to verify my understanding keeping in mind I have a one master and one slave computer. When the master gets the low batt/noAC signal it initiates a broadcast packet(s) on port 3493. 1) Is this correct? Then the slave computer must have this port open and it listens on this port for the shut-down command. 2) Is this correct? On the slave if I run the following: steve at MyDesktop:~$

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.).
