Hello, First of all, i am new at the list and i have several questions about ocfs2 performance. Where i am working i am having huge performance problens with ocfs2. Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI. ( acctualy 3 LUNS, 3 ocfs2 clusters ) I am not the one who configured the envoriment, but it is making the performance of my MAIL

There is a bug in ocfs2 1.4 if you are using it you should be looking for upgrading to ocfs2 1.6 I have several performance problens with ocfs2 but now i guess the problem is the webmail client that we are using. I have several post here about it. I will write a new one as soon as i found the solution. Anyway, why use lmtp over lda ? My setup have about 5000 active acounts all in maildir.

I've been following the instrunctions in <http://wiki.centos.org/HowTos/Amavisd> for installing Amavisd, Clamav and SpamAssassin on top of postfix/dovecot . Dovecot is working fine, but I want to deal with spam email. (I am using sendmail/dovecot with procmail and spamassassin on another server, but decided to go over to postfix on this server when I saw it is now the CentOS default.)

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw.

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Folks, At what point in iowait should I start to worry about having a bottleneck, or is this something that can't be answerd with a single integer? According to sar, after my last reboot to turn off hyperthreading as a test, at one time, I see 4.9% iowait, but then one minute later, it droped back to 0.01%, and rarely even gets to 1.0%, at least what I remember from yesterday. ?

Hi Folks, I'm having some problens using the RMySQL under R 1.7.0 (1.7.1) for Windows. Actualy, It's not available for download at Packages > Install packages from CRAN. I searched and download a version, but I just can't install it. I used tom use rmysql with an old version of R, and I remember it was "suported" by CRAN. I have already downloaded the DBI package.

We are struggling with a strange problem. When we have some VMWare clients running (mostly MS windows clients), than the IO-write performance on the host becomes very bad. The guest os's do not do anything, just having them started, sitting at the login prompt, is enough to trigger the problem. The host has plenty of 4G of RAM, and all clients fit easily into the space. The disksystem is a

Ehlo all, I've been working on a migration of about 240K users from one server with qmail, courier imap, maildrop and ldap to postfix, dovecot, lda +sieve. Before the migration the server and the storage were always on high load. Before migration: Storage IOPs = 4600 Read average = ?2800 ?Write average = 1800 Storage CPU (Raid5) Crl0 = 50% Crl1 = 50% Server Load = 120 %user = 35

First of all i would like to thanks Timo for the excellent job done in dovecot. We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using. So lets begin: We are using dovecot 2.0.6 with maildir in an ocfs2 partiton. It is pretty slow access in peak time, but it is related to
