Hi, everyone, there is a VM in the HostedEngine virtual machine that has been paused due to a storage I/O error, but engine manager services are normal, what is the problem? _______________________________________________
Which kind of storage? Sometimes when you have block based storage (FC, iSCSI) and you have a disk configured as thin provisioned, it could happen if heavy and/or rapid I/O and LVM resize operations don't satisfy timing needed If this is your case and you think you need enough sustained I/O in one VM you should configure its related disk as preallocated. See this thread about 2 years ago for example: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/S3LXEJV3V4CIOTQ... HIH, Gianluca
