The reason I am asking this question is there is atleast one file db.backup1 which is owned by cyrus:mail. mount points are : > /etc/artica-cluster/dispatcher-2.vol on /var/spool/cyrus/mail-clustered > type fuse.glusterfs (rw,allow_other,default_permissions,max_read=131072) > /etc/artica-cluster/dispatcher-1.vol on /var/lib/cyrus-clustered type > fuse.glusterfs (rw,allow_other,default_permissions,max_read=13107 > > how to force the client to mount has a specific user in order to not > corrupt the permissions settings ? > > > > > > > -------- Message initial -------- > *De*: Raghavendra G <raghavendra at gluster.com<Raghavendra%20G%20%3craghavendra at gluster.com%3e> > > > *?*: david <david at touzeau.eu <david%20%3cdavid at touzeau.eu%3e>> > *Sujet*: Re: try to understand how it works... > *Date*: Sun, 27 Dec 2009 19:00:18 +0400 > > > I meant, you can have the cyrus-imap installation directory on glusterfs > mount point, which helps you to maintain the mail directory and indexation > directory on gluster mount thereby replicating the contents of both the > directories. > > 2009/12/27 raghavendra <raghavendra at gluster.com> > > > > On Sun, Dec 27, 2009 at 6:27 PM, David Touzeau <david at touzeau.eu> wrote: > > Thanks for this answer > > i real production mode, i would like to create a cluster for cyrus-imap > > cyrus-imap use 2 directories. > /var/lib/cyrus > /var/spool/cyrus/mail > > I have 3 servers with cyrus-imap installed. > The goal is when a mail is saved on one of these servers in > /var/spool/cyrus/mail and in /var/lib/cyrus (indexation directory) it is > automatically replicated on the 2 servers. > > According your answer how i can create this kind of structure ? > > > You can have this by maintaining /var as a glusterfs mount-point (the > configuration used to mount glusterfs should have replicate). > > > > > > > -------- Message initial -------- > *De*: Raghavendra G <raghavendra at gluster.com<Raghavendra%20G%20%3craghavendra at gluster.com%3e> > > > *?*: david <david at touzeau.eu <david%20%3cdavid at touzeau.eu%3e>> > *Cc*: gluster-users <gluster-users at gluster.org<gluster-users%20%3cgluster-users at gluster.org%3e> > > > *Sujet*: Re: try to understand how it works... > *Date*: Sun, 27 Dec 2009 18:03:06 +0400 > > > > > Hi David, > > Please find the comments inlined below. > > On Sun, Dec 27, 2009 at 4:26 PM, David Touzeau <david at touzeau.eu> wrote: > > Dear > > My english is poor but after several research i will not really > understand how the replication works. > I have created 3 clusters server that share 2 directories in > cluster/replicate mode > > /home/replicate > /home/replicate2 > > each server mount the pool clusters in /mnt/replicate > and /mnt/replicate2 > > if i add a file in /home/replicate in one node, nothing happen in others > node. > The file is not added in the desired folder /home/replicate on others > nodes. > > > you should not do any filesystem operations on the back-end directory > directly.
