Dear All,
Previously we have used
CentOS4.4 release with Supported Cluster Suite and DRBD 8.0.0
Active/passive (failover)
We have build the DRBD 8.0.0 Source in CentOS4.4 Setup
We have configured the DRBD Resource with default OS installed LVM
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition
and its working fine
Partition Tables are listed below
=================================
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vgroot-LogVol02
3.0G 1.1G 1.7G 39% /
/dev/mapper/vgroot-LogVol03
11G 8.5G 1.7G 84% /usr
/dev/hda1 494M 37M 432M 8% /boot
tmpfs 248M 0 248M 0% /dev/shm
/dev/mapper/vgroot-LogVol01
8.5G 148M 7.9G 2% /home
/dev/mapper/vgroot-LogVol00
13G 161M 12G 2% /backup
Currently we are migrating to CentOS5.5
Step 1: We have migrated to CentOS5.5 Alone and Used Older DRBD 8.0.0
Version
We have build the DRBD 8.0.0 Source in CentOS5.5 Setup
We have configured the DRBD Resource with default OS installed LVM
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition
The DRBD Meta data created successfully, but DRBD Module Load failed
Errors are listed below
=======================
[root@corviewprimary user]# service drbd start
Starting DRBD resources: Can not load the drbd module.
[root@corviewprimary user]#
[root@corviewprimary user]# modprobe drbd
FATAL: Error inserting drbd
(/lib/modules/2.6.18-194.3.1.el5xen/kernel/drivers/block/drbd.ko):
Invalid argument
[root@corviewprimary user]#
Step 2: We have updated DRBD from 8.0.0 to 8.3.8
We have build the DRDB 8.3.8 Source in CentOS5.5 Setup
We have configured the DRBD Resource with default OS installed LVM
(/dev/mapper/vgroot-LogVol00 and /dev/mapper/vgroot-LogVol01) Partition
and its not working
We got the following errors on meta data creation
=================================================
[root@corviewprimary ~]# drbdadm create-md drbd0

You need to either
* use external meta data (recommended)
* shrink that filesystem first
* zero out the device (destroy the filesystem)

Please help us to use DRBD etiter 8.0.0 or 8.3.8 with CentOS5.5
Thanks in Advance.
