CentOS 6.8 With Current Kernel Fails With Pm-hibernate (cifsd Refuses To Freeze)

Now, this is not apparently very common to CentOS or EL server, but I
need to hibernate one of myservers after a batch job daily. Current kernel appears to fail with pm-hibernate now.

$ cat /etc/redhat-release CentOS release 6.8 (Final)

$ uname -a Linux xxxx 2.6.32-642.3.1.el6.x86_64 #1 SMP Tue Jul 12 18:30:56 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux

pm-hibernate tries but apparently fails.

OK. Last line says the process causing this is cifsd.

Anything to fix this?

  • OK. I fixed this case just by dismounting the share before hibernate, but I’ll leave this here anyway. Just a historic note or something ;)

  • Hello Jari,

    I think this is a very common issue: cifs vs hibernation, it’s not only this kernel, nor CentOS6. I tried hard when facing this issue, and automount could provide good results in auto-unmounting, but it’s far from a 100% success. Manually unmounting before hibernating is for now the only solution I’ve found.

    Regards,
