Re: Help with drbd and clustering virtual domains with Xen.

yes you can do that of course, but obviously he didn't shrink his fs before trying to use it (look at the message drbd returns when trying to create the metadata) IF you have to start from scratch, it's easier to just create the fs after the drbd initialization, and surely if you plan to setup drbd ...

Help with drbd and clustering virtual domains with Xen.

First of all, you need to read the whole DRBD doc if you plan to use LVM with DRBD (which the quick-and-dirty page on the centos wiki doesn't cover .. and i'm to blame as i wrote it a *long* time ago ...) You can use a LVM logical volume under a drbd block device, or on top (using a drbd device as a...

Centos 5 Cluster

My personal advice would be to use Heartbeat/Pacemaker. You have to know (if you don't already) that linux-ha.org (heartbeat) is now maintained by DRBD/Linbit so integration is of course working out-of-the-box. I'd also skip packages from CentOS Extras , as they are quite 'old' . You can fetch newer...

Re: Strange replication using DRBD 8.3.2

Hi there .. If you need to test DRBD, you'd better start with the 8.3.7 packages from the CentOS-testing repo : i use them on two production nodes for more than one week without any 'glitch'. What about your config ? are you using protocol C ? can you paste your /etc/drbd.conf ? What about `watch ca...

GFS question

Regarding fending you have to be sure that you have hardware you can use to 'fence/kill' other non-responding nodes in your clusters. That can be a remote power supply (reachable on the network) a blade chassis, a ipmi interface, etc, etc .. More details upstream : * http://www.redhat.com/docs/en-US...

Samba PDC+LDAP, failed to join domain for Win2k8

You'll have exactly the same issue with Windows 7 machines and it's a known issue with Samba 3.0.x packages : they are incompatible So you'll have to use newer Samba packages and (actually) they are only available in third-party repositories, like http://www.sambaenterprise.org with its yum repo bei...

Apple Xserve Install (Intel)

Well, as the grub supplied with CentOS isn't EFI aware, you'd better have to test another boot loader.
Depending if you keep an OSX partition, you can try rEFIT (http://refit.sourceforge.net/) : i use it to dual-boot between CentOS 5.x and OSX on an iMac

Re: Restore data from LVM Mirror

Yes, but only in a cluster .. and i've never used it and used other replication tool instead of cmirror .. The doc covers your question (about both creating the lvm mirror and the recovery) : - creating : http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Logical_Volume_Manager_Admin...

Restore data from LVM Mirror

What do you mean by 'lvm in mirror raid 1' ?
Do you mean two physical disks/partitions used with mdadm to assemble md device (raid 1) on which you have configured a VG/LV ?
