Team, I''m trying to figure out how to run 2 rails apps on one host. I ran an experiment: cd /tmp/ rails app1 rails app2 cd app1 script/server rails put a copy of lighttpd.conf in /tmp/app1/config/ and then started lighttpd http://localhost:3000 gave me the splash page. I shutdown the server I added something to /tmp/app1/config/lighttpd.conf server.modules = (

Hi all, I am facing a problem while using rails "migrate" feature for creating tables in a database. Following are the details. I have 2 applications say "app1" & "app2". I want both of them to use same database say "testdb". For "app1", I create 3 models which in turn create 3 migration files with prefix, 001_, 002_ & 003_. Now I

hey all, I have an app working great with apache2 and mongrel_cluster. However, I''m trying to run another application and now when I go to app1.comit falls to app2.com and the opposite. That''s probably because I messed up somewhere with the cluster. this is the content of my conf.d/app1.proxy_cluster.conf: <Proxy balancer://mongrel_cluster> BalancerMember

Sorry to bother you with a Rails "newbie"-like question, but I have been tearing my hair out for a couple of days with the deployment scenario I am trying to setup. I use a service provider that supports multiple domains via Virtual Hosts. I have all the software installed and "working". I want to deploy two apps under my domain and have the following in my .conf file:

I just finished updating our internal site, which hosts multiple Rails apps, to Apache 2.2.3. It also has a TWiki rewritten into the root, ViewVC mounted on /cvs, and /server-status and /server-info. <VirtualHost *:80> ServerName int.example.com ServerAlias int CustomLog /var/www/logs/int.example.com/access.log combined ErrorLog /var/www/logs/int.example.com/error.log [...]

I am using the ssh port forwarding feature. My configuration is as follows: On my server machine, running sshd, and app1. On my client machine, running ssh (client) and app2. The client connects to the server requesting remote port forwarding from port X on the server machine to port Y on the client machine. app2 is listening on port Y on the client machine. app1 connects to port X

I should add that additional testing has shown that only accessing files is held up, IO is not interrupted for existing transfers. I think this points to the heat metadata in the sqlite DB for the tier, is it possible that a table is temporarily locked while the promotion daemon runs so the calls to update the access count on files are blocked?

Thanks for the info, Hari. Sorry about the bad gluster volume info, I grabbed that from a file not realizing it was out of date. Here's a current configuration showing the active hot tier: [root at pod-sjc1-gluster1 ~]# gluster volume info Volume Name: gv0 Type: Tier Volume ID: d490a9ec-f9c8-4f10-a7f3-e1b6d3ced196 Status: Started Snapshot Count: 13 Number of Bricks: 8 Transport-type: tcp Hot

For what it's worth here, after I added a hot tier to the pool, the brick sizes are now reporting the correct size of all bricks combined instead of just one brick. Not sure if that gives you any clues for this... maybe adding another brick to the pool would have a similar effect?

The sizes of the files are extremely varied, there are millions of small (<1 MB) files and thousands of files larger than 1 GB. Attached is the tier log for gluster1 and gluster2. These are full of "demotion failed" messages, which is also shown in the status: [root at pod-sjc1-gluster1 gv0]# gluster volume tier gv0 status Node Promoted files Demoted files

Hi Chris, here is a link to the settings needed for VM storage: https://github.com/gluster/glusterfs/blob/03592930239c3b43cbbdce17607c099ae075fd6d/extras/group-virt.example#L4 You can also ask in ovirt-users for real-world settings.Test well before changing production!!!

Chris: Whilst I don't know what is the issue nor the root cause of your issue with using GlusterFS with Proxmox, but I am going to guess that you might already know that Proxmox "natively" supports Ceph, which the Wikipedia article for it says that it is a distributed object storage system. Maybe that might work better with Proxmox? Hope this helps. Sorry that I wasn't able

We use qcow2 with libvirt based kvm on many small clusters and have found it to be exremely reliable though maybe not the fastest, though some of that is most of our storage is SATA SSDs in a software RAID1 config for each brick.

On oVirt / Redhat Virtualization, the following Gluster volumes settings are recommended to be applied (preferably at the creation of the volume) These settings are important for data reliability, ( Note that Replica 3 or Replica 2+1 is expected ) performance.quick-read=off performance.read-ahead=off performance.io-cache=off performance.low-prio-threads=32 network.remote-dio=enable

Hi, I've got this strange problem where a striped endpoint will crash when I try to use cp to copy files off of it but not when I use rsync to copy files off: [user at gluster5 user]$ cp -r Python-2.6.4/ ~/tmp/ cp: reading `Python-2.6.4/Lib/lib2to3/tests/data/fixers/myfixes/__init__.py': Software caused connection abort cp: closing

Hi Tom, The volume info doesn't show the hot bricks. I think you have took the volume info output before attaching the hot tier. Can you send the volume info of the current setup where you see this issue. The logs you sent are from a later point in time. The issue is hit earlier than the logs what is available in the log. I need the logs from an earlier time. And along with the entire tier
