Hi Folks, Anybody have any recent experience building a small cluster that combines GlusterFS and Xen (with bonus points for a Debian environment)? We''re getting ready to shift from a 2-node Xen/Pacemaker/DRBD environment to a 4-node environment - and I''d really like to be able to create/migrate/failover/delete VMs transparently across all 4 nodes. Seems like Gluster might

Sorry for my ignorance. When I create xen virtual machines on lvm I need to create a filesystem on lvm container? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Folks, I find myself trying to expand a 2-node high-availability cluster from to a 4-node cluster. I'm running Xen virtualization, and currently using DRBD to mirror data, and pacemaker to failover cleanly. The thing is, I'm trying to add 2 nodes to the cluster, and DRBD doesn't scale. Also, as a function of rackspace limits, and the hardware at hand, I can't separate

Hi Folks, I''ve been getting just a little fed up with the state of Xen on Debian Lenny - there are a couple of known bugs that lead to periodic kernel panics - but fixes haven''t made it into the Lenny distribution. I''m sort of waiting to see how things shake out with Debian Squeeze, when it becomes stable, but... I''ve been noticing that Suse (both the

Hi, i''ve a problem with drbd 0.7.10 module on an xenU OS (testing). I''ve compiling drbd with "make clean all" then "make install" without error. modprobe drbd OK with no error too and now and trying to start drdb /etc/init.d/drbd start Starting DRBD resources: can not open /dev/drbd0: No such device or address [ d0 can not open /dev/drbd0: No such device

Hi All, I plan to use Xen (most probably XCP) to virtualize two servers: one running OpenBSD, the other running FreeBSD. These both servers will be running more or less headless (at least without any graphical environment). I would want to add a third server (most probably a Debian Squeeze or Freebsd) to have a desktop (light, probably IceWM or XFCE). The physical machine will have VTx but

FYI: This bug also breaks user supplied scripts (/etc/xen/scripts/block-*) that are needed to handle block device mounting other than "phy:" and "file:" disks.

Hello. I plan to use OCFS2 + DRBD for email server. Problem: I use "seeker" for testing http://www.linuxinsight.com/how_fast_is_your_disk.html And get this: Results: 65 seeks/second, 15.23 ms random access time Then I do rm of many files - it fals to 10 seeks/second and performance is terrible. What can I do to increase it? What`s wrong? Below is many info. What we have: Debian

Hi Folks, I'm trying to install Debian onto a headless server (Supermicro X8SIE-LN4F motherboard). The on-board IPMI BMC redirects the serial port to COM3, and I can talk to it just fine over a remote console connection. I've been trying to install Debian remotely, and have the DHCP and TFTP servers working, and things seem to work (at least into the Splash screen) if I'm using

I need to run xen 3.3 with drbd82 in centOS 5.2 (in order to utilize blockdrbd feature for drbd8). Any resources on this? Thanks Paras. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with

Hi all ! Is anyone using xen kernel + drbd 8.2.4 ? I don''t know exactly if my problems come from the addition of the two packages, or from drbd 8.2.4, but I encoutered kernel panic 2 times when trying to do first sync of drbd resources :s Cheers, -- Serge Dewailly _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Please excuse a wee bit of cross posting here. It seems that the questions list may not be the appropriate place for this as I've found a number of unanswered posts involving this topic. My FreeBSD workstations are setup with pam_ldap to a centralized openldap server for authentication. This works perfectly for native FreeBSD applications. What I'm running into an issue with are Linux

I have set up an cluster with ocfs2 on top of drbd in primary/primary mode. As long as the datadir is in /var/lib/mysql, everything works fine. But as soon as I put the datadir on the ocfs2 filesystem /mnt/data/mysql mysql fails with: [Ubuntu] root at fs2:/etc# mysqld --safe-mode 090930 18:08:14 [Warning] Can't create test file /mnt/data/mysql/fs2.lower-test 090930 18:08:14 [Warning]

Hey all! I''m currently in the process of trying to debug a (possibly!) Xen-related issue (with Kernel 3.2.9-vanilla as Dom0, and Xen 4.1.2 [almost] vanilla, except for a patch for CVE-2012-0029), where a system freezes without me being able to ascertain a triggering event. The system console is completely unresponsive in the event of hangs (i.e., displays motd and the login prompt,

Hi everyone, I´m using Citrix XenServer with DRBD. But something went really wrong, so I need a fresh Install.My only question is, how can I mount the DRBD partition? It is /dev/drbd1 , but if I try to mount it, I need to provide the filesystem type. Does anyone know what I have to do? I only need to copy some data from it, it doesn’t matter if it will be destroyed. I tried GFS as filesystem

Hello all, has someone worked with DRBD (http://www.drbd.org) for HA of mail storage? if so, does it have stability issues? comments and experiences are thanked :) Thanks, Rodolfo.
