similar to: Samba Read-only redundancy

Hi, right now I am using only one external server as a gateway for the internal servers. I would like to enable a fail-over on a second server. To implement the floating VIP, should I use heartbeat+pacemaker? Or is there something more "lightweight"? Basically, I just need server2 up the VIP when server1 is down, and server2 down the VIP when server1 is back up (or server 1 does not up

OK. Everything is going great for 4 years on my FC3 Samba Version 3.0.3-5. Now all of a sudden, when someone opens a Word/Excel file on a Samba share, it changes the user Owner to that user as well as modifies the permissions to r-x and leaves the group/permission bits/owner setting alone. I have the root directories for all shares with the u and g sticky bits set on, but it is not enforcing

Hi, I've setup two server A + B (debian etch) with drbd + heartbeat in active/passive mode. If the primary server A fails, the shared storage is mounted on B, the virtual ip A-vip moves to the new primary B and samba is started by heartbeat. This works well, but I'm not sure which samba files should be identical on both server. Both have a dedicated machine account at the moment.

Hello everyone! I am working on implementing my first Gluster/Ganesha NFS setup and I am flowing this guide: http://blog.gluster.org/2015/10/linux-scale-out-nfsv4-using-nfs-ganesha-and-glusterfs-one-step-at-a-time Everything is working fine. I've got Gluster and Ganesha NFS working and I have VIPs on each node and it is failing over fine, if a little slowly. However, the VIPs don't

Some of the Red Hat Enterprise Linux servers in our environment sometimes get assigned virtual IP addresses (eth0:1, eth0:2, etc). Puppet Dashboard''s parameters seem like an ideal way to define and provision virtual IPs on these servers. One could create a "vip1" parameter on a node, and define a value of the IP address to use for that vip. A manifest could then be written to

Hi System debian 8.11 and dovecot-2.2.36.4 My webmail is roundcube with imapproxy. I have one problem. My dovecot servers is are in a cluster with keepalived like: dovecot1----VIP-IP--------dovecot2 All works fine I have a problem with imapproxy when a server dovecot1 had a problem (kernel panic sic!) Keepalived works perfecty and moved VIP to dovecot2 - all works fine for normal users but

Hello, I am working on setting up an Active/Passive Samba cluster on Ubuntu 14.04 using Samba 4.1.6. Samba will be sharing an NFS mount so that it can be accessible to CIFS clients. Thus, the server setup is as follows: -- cifs0 -- / \ / \ NFS_Server VIP --- CIFS clients \ / \ /

My samba shares aren't working with ACL access since the upgrade. Here is an example of the error from /var/log/messages Dec 14 12:44:17 gfm-atlas smbd[14365]: [2006/12/14 12:44:17, 0] smbd/service.c:make_connection_snum(911) Dec 14 12:44:17 gfm-atlas smbd[14365]: '/usr/GFM_Shares/Users/Receiving' does not exist or permission denied when connecting to [GF_Receiving] Error was

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup.

Hi, list, I'm going to deploy postfix + dovecot + CephFS( as Mail Storage). Basically I want to use two servers for them, which is kind of HA. My idea is that using keepalived or Pacemaker to host a VIP, which could fail over the other server once one is down. And I'll use Haproxy or Nginx to schedule connections to one of those server based on source IP( Session stickiness),

Hi, I have a testing multihome setup, with the default gateway being one of the links and using policy routing to honor requests for a specific link. Everything works as expected when I request a specific IP to bind to. But if I request a specific interface things fall apart in ways that I can not explain: default gw (WORKS) ---------- rabbit@Thesaurus:~$ ping -c 1 yahoo.com PING yahoo.com

H? all; i need your helps on setting the virtual ip. I am trying to setup static virtual ip on CenOS7. but I want my VIP to should not open when rebooting.

Hello, after upgrading Shorewall (see subject) and Gentoo-Linux (from Kernel 2.6.12 to 2.6.15, both with Gentoo patches, e.g. not Vanilla) the firewall on our load balancer rejects HTTP packets for the VIP with >Mar 5 23:22:51 balance Shorewall:all2all:REJECT:IN= OUT=eth0 >SRC=XX.XXX.XXX.XXX >DST=XXX.XXX.XXX.

We have a queue monitoring application running so we can see the caller ID of callers in a queue. If we see a VIP in the queue, is there any method to force that call to be first in line? If there's a softphone, or queue managing application already written that does this, I'd love to know.

Hi, I have HA firewalls configuration (keepalived) on one site. Each firewall has its own IP and a Virtual IP (VIP) that keepalived activate on one of the firewall (active/passive HA configuration). I think I can set all two firewalls with same configuration, generating key pairs on one firewall and copying that to the second, so the remote host can see always one of the other firewall as the

Hi, guys, Can you give me an example of solr usage in dovecot? As far as I know, you can search email easily by MUA like outlook, so which role does solr play? And based on https://dovecot.org/pipermail/dovecot/2019-April/115575.html I'm going to use an VIP to host 2 mail servers. Currently, it works in fail over and fail back test except solr index, so how to resolve this? Is it

i'm trying to setup LVS, and tried both the lvs-dr and the lvs-nat, but can't get any to work. I'm hoping people here can answer a few questions that might help and shed light onto the situation? #1 with regards to the Real Servers, is there anything that needs to be configured other that the http service? I ask this, because I suspect yes, and it has to do with what type of LVS you

My production imap is currently UWIMAP with mbox.. One of the problems commonly observed is mailbox lock loss, which happens when: a) a VIP has multiple secretaries accessing a single mailbox (actually, they are professional enough to have figured the realities of conflicting access and rarely have a problem), b) somebody leaving their machine on at home and coming in and firing up their work
