Hello,
I'm experiencing a weird problem today, the VMs on one of the datastore -which is backed by a LUN on NETAPP FS8040- are neither able to be vmoted, storage vmoted, or even powering them on (if I power off any of them). And when I try to create a folder (for testing) on that datastore via SSH, the operation fails with the error "input/output locked". VMware support team have investigated the issue, but nothing is locking the VM files. Only one host has succeeded in creating and deleting a test folder on that datastore, but it's holding one of the victim VMs and I won't be able to reboot it (assuming that it's locking that datastore).
I'm using vSphere 6.5, and VMFS6
Note: other datastores no the same SAN are healthy.
What do you think guys?
