Hello,
We had an issue today where our storage (Netapp) triggered fail lover between controllers.
During that process our Linux based VMs went in to read-only drive state to avoid data loss or corruption.
When storage recovered we had to reboot Linux VMs to get out from read-only state,
CentOS systems rebooted with out issue - repaired itself and booted to normal read write drive state.
Ubuntu VMs had to be re scanned after boot to come back online and few did not boot up at all with swap partition missing / not able to mount.
Windows VMs were not affected.
Here is our setup:
NetApp Storage - dual controller configured for HA.
ESXi - 6.0.0, 7967664 with multi-path connection to storage via ISCSI
Ubuntu 16.04.3 LTS xenial - Disk Time out set to 180 - no multi path connectivity.
Is there specific Ubuntu setting for vmware that we are missing? Or maybe ESXi need specific patching?
From what i was able to find online ESXi before 6 were having this issue and Linux with older kernel but it should be patched with what we have right now.
I appreciate any suggestions.
Martin
