similar to: netapp/maildir/dovecot performance

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

Hi all... How can deliver messages to a subfolder using the LDA? For example, I want a message to joe+spam at abc.com to be placed inside the 'spam' subfolder. Any hint is appreciated. Thanks ;)

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

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.).

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

(Using dovecot 1.0 RC7 on Fedora Core 5) <scene set> Hitherto we have used UW-IMAP on a "farm" of Linux machines mounting NFS from a NetApp. (The UW-IMAP author doesn't like use of NFS, but with careful use of NFS mount arguments ('noac,actimeo=0' etc.) and trying to ensure that all activity for a given user takes place within one machine in the farm, we seem to

I have a 1.5 TB (1,475,720,773,632) partition that I wanted to convert from ext4 to btrfs. It is currently used as / for ubuntu 10.10. I booted into 11.04 beta2 and tried a ''btrfs-convert /dev/sdc1'', but after about 20 minutes it segfaulted. I performed a: sck.ext4 -cDfty -C 0 /dev/sdc1 After everything was clean, I downloaded the debugging symbols for btrfs-convert and

We have a 2-node Oracle RAC that keeps getting the following error: kernel: nfs: RPC call returned error 88 The storage being mounted is netapp. We don't see any errors/issues on the storage itself or the switches this client is connecting thru. The NFS network is a 2-interface ( 2 x 1Gb UTP) bond which shows no errors of any kind. We are mounting with the following mount options:

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 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?

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:~$

Hi all... The prefetch entry in the wiki says: "If you're using Dovecot's local delivery agent, you'll still need a valid userdb which it can use to locate the users. You can do this by adding a normal sql/ldap userdb after userdb prefetch." (http://wiki.dovecot.org/UserDatabase/Prefetch) My question is: Does it need to be a SQL/LDAP userdb? How about static or passwd?

Hi All, I am looking for advice on how to cure a constantly-crashing NFS server which crashes every few hours, or at least, every few days. The kernel log file (below) points toward NFS as a likely cause. The system disk is a 3ware 8000 series RAID1 mirror. The data disk is using a 3Ware 9000 controller to produce two RAID1 devices; these are then striped (RAID0) in software to form a RAID 10

We have and nfs mount from a windows pc nfs server. A file is created on the server, but can take as long as 50 seconds to become available on the client. We are running Centos 5.2 (final), using NFS version 3. Is there anything we can do from the client side to see the file more quickly. The files are very small, usually about 1k _____________________________________ "He's no

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

No, the slave computer's upsmon process connects to the master (via TCP, so

I have made changes but it is still the same. That is when the server gets the lowbat/noAC signal it does shut down as expected but the slave does not. Perhaps it makes sense for me to list the present settings: On the Master: nut.conf MODE=netserver ups.conf [sdrups] driver = genericups port = /dev/ttyS1 desc = "For Server &
