MAPR-FS para NFS de ONTAP

Colaboradores
PDF

Esta sección proporciona los pasos detallados necesarios para mover datos de MapR-FS a NFS de ONTAP mediante NetApp XCP.

  1. Aprovisione tres LUN por cada nodo de MapR y dé la propiedad de los LUN de todos los nodos de MapR.

  2. Durante la instalación, seleccione LUN recientemente añadidas para discos de clúster de MapR que se utilizan para MapR-FS.

  3. Instale un clúster de MapR de acuerdo con "Documentación de MAPR 6.1".

  4. Compruebe las operaciones básicas de Hadoop mediante comandos MapReduce como hadoop jar xxx.

  5. Mantenga los datos de sus clientes en MapR-FS. Por ejemplo, generamos aproximadamente un terabyte de datos de muestra en MapR-FS con Teragen.

  6. Configure MapR-FS como exportación NFS.

    1. Deshabilite el servicio nlockmgr en todos los nodos de MapR.

      root@workr-138: ~$ rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100003    4   tcp   2049  nfs
    100227    3   tcp   2049  nfs_acl
    100003    4   udp   2049  nfs
    100227    3   udp   2049  nfs_acl
    100021    3   udp  55270  nlockmgr
    100021    4   udp  55270  nlockmgr
    100021    3   tcp  35025  nlockmgr
    100021    4   tcp  35025  nlockmgr
    100003    3   tcp   2049  nfs
    100005    3   tcp   2049  mountd
    100005    1   tcp   2049  mountd
    100005    3   udp   2049  mountd
    100005    1   udp   2049  mountd
root@workr-138: ~$
 
root@workr-138: ~$ rpcinfo -d 100021 3
root@workr-138: ~$ rpcinfo -d 100021 4

    2. Exporte carpetas específicas de MapR-FS en todos los nodos de MapR del /opt/mapr/conf/exports archivo. No exporte la carpeta principal con permisos diferentes al exportar subcarpetas.

      [mapr@workr-138 ~]$ cat /opt/mapr/conf/exports
# Sample Exports file
# for /mapr exports
# <Path> <exports_control>
#access_control -> order is specific to default
# list the hosts before specifying a default for all
#  a.b.c.d,1.2.3.4(ro) d.e.f.g(ro) (rw)
#  enforces ro for a.b.c.d & 1.2.3.4 and everybody else is rw
# special path to export clusters in mapr-clusters.conf. To disable exporting,
# comment it out. to restrict access use the exports_control
#
#/mapr (rw)
#karthik
/mapr/my.cluster.com/tmp/testnfs /maprnfs3 (rw)
#to export only certain clusters, comment out the /mapr & uncomment.
#/mapr/clustername (rw)
#to export /mapr only to certain hosts (using exports_control)
#/mapr a.b.c.d(rw),e.f.g.h(ro)
# export /mapr/cluster1 rw to a.b.c.d & ro to e.f.g.h (denied for others)
#/mapr/cluster1 a.b.c.d(rw),e.f.g.h(ro)
# export /mapr/cluster2 only to e.f.g.h (denied for others)
#/mapr/cluster2 e.f.g.h(rw)
# export /mapr/cluster3 rw to e.f.g.h & ro to others
#/mapr/cluster2 e.f.g.h(rw) (ro)
#to export a certain cluster, volume or a subdirectory as an alias,
#comment out  /mapr & uncomment
#/mapr/clustername         /alias1 (rw)
#/mapr/clustername/vol     /alias2 (rw)
#/mapr/clustername/vol/dir /alias3 (rw)
#only the alias will be visible/exposed to the nfs client not the mapr path, host options as before
[mapr@workr-138 ~]$

  7. Actualice el servicio NFS de MapR-FS.

    root@workr-138: tmp$ maprcli nfsmgmt refreshexports
ERROR (22) -  You do not have a ticket to communicate with 127.0.0.1:9998. Retry after obtaining a new ticket using maprlogin
root@workr-138: tmp$ su - mapr
[mapr@workr-138 ~]$ maprlogin password -cluster my.cluster.com
[Password for user 'mapr' at cluster 'my.cluster.com': ]
MapR credentials of user 'mapr' for cluster 'my.cluster.com' are written to '/tmp/maprticket_5000'
[mapr@workr-138 ~]$ maprcli nfsmgmt refreshexports

  8. Asigne un rango IP virtual a un servidor específico o un conjunto de servidores del clúster de MapR. A continuación, el clúster de MapR asigna una IP a un servidor específico para el acceso a los datos NFS. Las IP posibilitan la alta disponibilidad, lo cual significa que, si se produce un error en un servidor o una red con una IP en particular, se puede utilizar la siguiente IP del rango de IP para el acceso a NFS.

    Nota Si desea proporcionar acceso NFS desde todos los nodos de MapR, puede asignar un conjunto de IP virtuales a cada servidor y usar los recursos de cada nodo de MapR para el acceso a datos NFS.

    Error: Falta la imagen gráfica

  9. Compruebe las IP virtuales asignadas en cada nodo de MapR y utilícela para el acceso a los datos NFS.

  10. Monte MapR-FS exportado por NFS con la IP virtual asignada para comprobar la operación NFS. Sin embargo, este paso no es necesario para la transferencia de datos con NetApp XCP.

  11. Configure XCP de NetApp para transferir datos desde la puerta de enlace NFS de MapR-FS a NFS de ONTAP.

    1. Configure la ubicación del catálogo para XCP.

      [root@hdp2 linux]# cat /opt/NetApp/xFiles/xcp/xcp.ini
# Sample xcp config
[xcp]
#catalog =  10.63.150.51:/gpfs1
catalog =  10.63.150.213:/nc_volume1

    2. Copie el archivo de licencia en /opt/NetApp/xFiles/xcp/.

      root@workr-138: src$ cd /opt/NetApp/xFiles/xcp/
root@workr-138: xcp$ ls -ltrha

    3. Active XCP mediante xcp activate comando.

    4. Compruebe el origen de la exportación NFS.
