VMware Esxi:Disk Consolidation Needed - Unable to access file since it is locked

From: Polin Wei

 系統出現 "Virtual machine disks consolidation is needed"




用 SSH 連到主機端, 查看 vmware.log
# vi vmware.log

2015-06-02T09:52:50.430Z| vmx| I120: [msg.nvram.wback1] Could not create '/vmfs/volumes/50eaa6a3-bd303b99-7190-3440b5c68358/PLM/PLM.nvram': Failed to lock the file 2015-06-02T09:52:50.430Z| vmx| I120: ---------------------------------------- 2015-06-02T09:52:50.454Z| vmx| W110: NVRAMMGR: Failed to create default NVRAM file (PLM.nvram)

使用指令 mkfstools -D 查看那台主機 lock ,
 # vmkfstools -D PLM.nvram

Lock [type 10c00001 offset 107448320 v 16455, hb offset 3289088

查到的 3440b5ca5488 即是 MAC 34:40:b5:ca:54:88,

示意圖:




方法一:
確定主機後, 將 host 進入 maintenance mode, 此時 DRS vMotioned all VMs to another host in the cluster , 然後 restarted the hostd service.

SSH 登入主機, 下指令: /etc/init.d/hostd restart
 
方法二:
若覺得  maintenance mode 要將所有 guest 移到別台 Host 工程太浩大, 那就
將 guest 移到這台Host, 再作 Consolidation 也是可以.


個人是覺得第二個方法最方便. 供參考
