磁盘不能自动mount上来的solution(solution for nfs disks can't be mounted automatically)

• Problem Description:
  • 1.The nfs disks have been set as mount automatically  in /etc/vfstab
  • 2.nfs disks didn't mount  after reboot machine.

• Diagnostic Analysis:
  • Check nfs service
    
    • Run svcs -a | grep nfs
      
    • The  state of " svc:/network/nfs/nlockmgr:default , svc:/network/nfs/status:default ,svc:/network/nfs/client:default " are disabled
    • 说明：nfs/client没有启，但是在enable nfs/client的时候，发现nfs/client会进入offline的状态。Run "svcs -d svc:/network/nfs/client:default"查看它依赖的服务会发现" svc:/network/nfs/nlockmgr:default , svc:/network/nfs/status:default “是disabled 状态，所以说是因为这两个依赖的服务没有启来，导致nfs/client启不来。

• Solution:
  • Enable " svc:/network/nfs/nlockmgr:default , svc:/network/nfs/status:default “ first, then enable "svc:/network/nfs/client:default ".
  • svcadm enable nfs/nlockmgr; svcadm enable nfs/status; svcadm enable nfs/client   <=======已验证这条可行
