OS: Windows Server 2012 ,10 Node Hyper-v cluster
Model: ProLiant BL460c Gen8
Storage: FC,HP 3PAR
Multiple Virtual Machine’s went into paused state throwing error “Disk(s) running out of space though 30% free space available
Only few Virtual machines went to paused state and observed all VM’s are coming from single volume let’s say Volume 1
Volume1 is having 30 % free space , checked with storage team whether the LUN is thick or thin as sometimes LUN may be exhausted if they allocated as thin. It is a thick LUN and no issues observed from storage
Tried to resume the VM, after sometime VM moving to pause state
Tried to move the CSV disk from one node to another – No Luck
Observed that there is no single recommended hotfix installed on any node in a cluster but all nodes are up to date with all critical patches
- Based on above findings, assumed that there is some known issues would be there as error is misleading us to DISK’s are running out of space though 30% free space available.
- As there was no single recommended hotfix installed in cluster , initially installed Hype-v 2012 hotfixes on one node and taken restart.
- Move the Victim volume to the recently restarted node. – No issues observed
- Post keeping an observation, installed all recommended hotfixes
Finally, I am unsure which hotfix resolved exactly but I have seen below forums where these issues addressed in KB2791729 but it is a private hotfix
