Agregar lun a rhel cluster 5

Verificamos las wwn online y pedimos la lun.

#   cat /sys/class/fc_host/*/port_name
0x21000024ff219f38
0x21000024ff219f39
0x21000024ff2194ac
0x21000024ff2194ad
#   cat /sys/class/fc_host/*/port_state

Una vez que nos asignaron las luns rescaneamos, identificamos la lun y la editamos el /etc/multipath.conf para modificarle el nombre. (TODO ESTO EN LOS DOS NODOS)

# rescan-scsi-bus.sh

# multipath -F; multipath -v2
create: mpath27 (360050768018285d270000000000005b5)  IBM,2145
[size=200G][features=0][hwhandler=0][n/a]
\_ round-robin 0 [prio=50][undef]
 \_ 1:0:1:26 sdcm 69:160 [undef][ready]
 \_ 2:0:1:26 sdco 69:192 [undef][ready]
\_ round-robin 0 [prio=10][undef]
 \_ 1:0:0:26 sdcl 69:144 [undef][ready]
 \_ 2:0:0:26 sdcn 69:176 [undef][ready]
 
# vi /etc/multipath.conf
 ### Agregamos algo como esto
         multipath {
               wwid                    360050768018285d270000000000005b5
               alias                   mp_storage_u11
        }
        
# multipath -F; multipath -v2       

Con el disco reconocido por el sistema operativo procedemos a formatearlo, agregarlo a lvm.
# fdisk /dev/mapper/mp_storage_u11

[ ponemos todas las opciones que van  n - p - 1 - enter - enter 
  t 8e w ]
  
# pvcreate /dev/mapper/mp_storage_u11p1
# vgcreate vgstorage_u11 /dev/mapper/mp_storage_u11p1
# lvcreate -n lv_u11 -l 100%FREE vgstorage_u11 

Aca faltaria crear el fs y agregarlo al cluster el tema es que el tipo de fs es gfs2 asi que hay que darle un vueltita de rosca mas.

Con gfs2.tool buscamos la etiquieta de locktable que tienen los fs montados y la cantidad de journals (deberia ser un journal por nodo que lo monta)

# gfs2_tool list

253:52 gatclu:u10
253:58 gatclu:utsm
253:57 gatclu:uarchive
253:60 gatclu:gfs2
253:53 gatclu:u08
253:51 gatclu:u07
253:50 gatclu:u06
253:48 gatclu:gfs2-u05
253:61 gatclu:u04
253:59 gatclu:u03
253:56 gatclu:u02
253:55 gatclu:u01
253:54 gatclu:u00

# gfs2_tool journals /u09
journal1 - 128MB
journal0 - 128MB
2 journal(s) found.

Creamos entonces los fs y los agregamos al cluster.

mkfs.gfs2  -p lock_dlm -t gatclu:u11 -j2 /dev/vgstorage_u11/lv_u11
mount -t gfs2 /dev/vgstorage_u11/lv_u11 /u11

vi /etc/cluster/cluster.conf 
### Cambiar la config_version en la seccion cluster
<cluster config_version="48" name="gatclu">
### Agrego en la seccion resources TENER en cuenta el fsid que no se repita
<clusterfs device="/dev/vgstorage_u11/lv_u11" force_unmount="1" fsid="58377" 

fstype="gfs2" mountpoint="/u11" name="gfs2-u11" options="noatime,defaults"/>
### Agrego en la seccion service
<clusterfs ref="gfs2-u11">
</clusterfs>

Una vez revisado todo updateo la configuracion del cluster:

ccs_tool update /etc/cluster/cluster.conf
