Boa noite ...
Estou tendo s�rios problemas ao implementar a solu��o de replica��o de
discos com o DRBD. A mensagem de erro � a abaixo:
root@alpha init.d]# /etc/ha.d/resource.d/datadisk start
Becoming primary on DRBD resource drbd0... [ OK ]
performing fsck on drbd0 [ OK ]
reiserfs_read_super: unable to read superblock on dev 2b:00

[root@alpha init.d]# mount

none on /proc type proc (rw)
/dev/hda2 on /usr type ext2 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
[root@alpha init.d]#
O m�dulo drbd.o est� carregado. Abaixo est� o meu /etc/fstab:
/dev/hda1 / ext2 defaults 1 1
/dev/hda2 /usr ext2 defaults 1 2
/dev/hda5 swap swap defaults 0 0
#/dev/hda6 /dados ext2 defaults 1 3
#/dev/hda4 /teste reiserfs defaults 0 0

/dev/cdrom /mnt/cdrom iso9660 user,noauto,ro 0 0

e este abaixo � o meu /etc/sysconfig/drbd/drbd0
# master and slave addr addr[:port]
# default port: 7788
# Important: don't use domain names here, only the hostnames
# as reported by hostname -s
MASTER_NODE="admin:7788"
SLAVE_NODE="alpha:7788"
# If you have machines with multiple NICs, you may want to specify
# the interface by it's IP address here.
#
# If you machines only have one NIC do not set these, BY LEAVING
# THEM WITH EMPTY QUOTES. Otherwise you will confuse init.d/drbd.
# That means, DO NOT COMMENT THEM OUT! :)
#
# If you use these fields, put any port identifies (:[0-9]+) here, you
# do not need to specify them at the *_NODE entries.
MASTER_IF=""
SLAVE_IF=""
# Options:
# -t --timeout val
# If communication blocks for val * 1/10 seconds,
# drbd falls back into unconnected operation.
# Default: 30 = 3 sec.
#
# -r --sync-rate val
# The synchronisations sends up to val KB per sec.
# Default: 250 = 250 KB/sec
#
# -k --skip-sync
# Instruct drbd not to do synchronisation.
#
# -s --tl-size val
# Sets the size of the transfer log(=TL). The TL is
# is used for dependency analysis. For long latency
# high bandwith links it might be necessary to set
# the size bigger than 256.# You will see error messages
in the system log
# if the TL is too small.
# Default: 256 entries
#
# -d --disk-size val
# Sets drbd's size. When set to 0 drbd negotiates the
# size with the remote node.
# A value different from 0 will allow drbd to operate even without
# a connection to the other node. Make sure sizes match!
# Default: 0 KB.
#
# -p --do-panic
# drbd will trigger a kernel panic if there is an
# IO error on the lower_device. May be usefull when
# drbd is used in a HA cluster.
OPTIONS=""
# Protocol used for this device
# protocol may be A, B or C.
PROTOCOL="B"
# Devices used in master and slave (may be different on each machine)
MASTER_DEVICE="/dev/nb0"
SLAVE_DEVICE="/dev/nb0"
# Partitions for drbd (can be a different partition on each machine)
MASTER_PARTITION="/dev/hda6"
SLAVE_PARTITION="/dev/hda4"
# fsck command (ALWAYS keep the -p for automatic error correction)
MASTER_FSCK="fsck -p -y"
SLAVE_FSCK="fsck -p -y"
Algu�m poderia me dar uma ajuda, j� li a documenta��o no site de quem
desenvolveu e a da Conectiva
(Manual do servidor), � qual na minha "humilde opini�o" nesta parte do
manual faltam dados
importantes.
Obrigado e desculpem o mail longoooooooo. :-)
