> while creating snapshot put host 1 in maintenance mode , snapshot creation
> fails and host resource state stuck in "ErrorInMaintenance" mode.
> STEPS TO REPRODUCE
> -------------------------------------
> -------------------------------------
> 1-Create advance zone->add pod->cluster->add 1 KVM host.
> 2-Create ha enable service offering
> 3-Deploy a VM using service offering(you have created in step 2)
> 4-Add another KVM host in same cluster which you have created in step 1
> 5-Click button create a snapshot from root volume
> 6-While step 5 is in progress put 1st host in maintenance mode
> EXPECTED RESULT
> ---------------------------------
> ---------------------------------
> 1-Snapshot should backed up successfully and host should go in maintenance
> mode
> ACTUAL RESULT
> --------------------------------
> -------------------------------
> 1-Snapshot creation failed
> 2- Host resource sate stuck in ErrorInmaintenance mode
> MY OBSERVATION
> ------------------------------
> ------------------------------
> 1-Snapshot creation happening properly if you put host in maintenance mode
> which is not hosting any vms
> 2- Without any maintenance activity snapshot creation is happening properly
> 3-Migration is happening properly without any snapshot activity
