Cách Fix

1. Check log

#tail -n 200 /var/parallels/DBO_S4.pvm/parallels.log

While checking the logs for the VM DBO_S4 (on the node: minicloud03) at
/var/parallels/DBO_S4.pvm/parallels.log, I found the following information:

--
/vdisk:7186:7195/ Error locking file
/var/parallels/DBO_S4.pvm/harddisk.hdd/harddisk.hdd [0]
05-21 11:59:21.841 F /vdisk:7186:7195/ Couldn't lock disk: 0x80021014
05-21 11:59:21.841 F /vdisk:7186:7195/ OpenDisk() returned error 0x80021014
05-21 11:59:21.842 F /ioctl:7186:7195/ descr 24 reopened to be 102399

2. Tìm ổ cứng đang chạy

#lsof 2>/dev/null | grep hdd

I tried to find out the HDD atached to it:

--
[root@minicloud03 DBO_S4.pvm]# lsof 2>/dev/null | grep hdd
prl_vm_ap 7186 root 41uW REG 0,21 0
967 /pstorage/minicloud/vmprivate/DBO_S4.pvm/harddisk.hdd/harddisk.hdd
prl_vm_ap 7186 root 42uW REG 0,21 7800356864
975
/pstorage/minicloud/vmprivate/DBO_S4.pvm/harddisk.hdd

/harddisk.hdd.0.{5fbaabe3-6958-40ff-92a7-860e329aab41}.hds
prl_vm_ap 7186 root 85uW REG 0,21 7800356864
975

/pstorage/minicloud/vmprivate/DBO_S4.pvm/harddisk.hdd/harddisk.hdd.0.{5fbaabe3-6958-40ff-92a7-860e329aab41}.hds

3. Stop VM

[root@minicloud03 DBO_S4.pvm]# prlctl stop DBO_S4
Stopping the VM...
The VM has been successfully stopped.

4. Tìm lại ổ cứng

[root@minicloud03 DBO_S4.pvm]# lsof 2>/dev/null | grep hdd

5. Gõ lệnh unmount các ổ cứng

[root@minicloud03 DBO_S4.pvm]#

""""""""""""
pstorage revoke /pstorage/minicloud/vmprivate/DBO_S4.pvm/harddisk.hdd/harddisk.hdd

"""""""""""""

6. Unregister the VM

#prlctl unregister DBO_SB

7.Register lại VM

#prlctl register /pstorage/minicloud/vmprivate/DBO_S4.pvn

8. Start lại VM

# prlctl start DBO_SB


Done

Chúc các bạn thành công!
