ESXi reports "All Paths Down" for ReadyNAS hosted NFS share
Hiya - looking for some feedback from the community on an issue I'm seeing. Thanks in advance for any insights. Some background: We're using two ReadyNAS 3200's to host virtual machines via NFS. ...
As an update...
I completed a full rebuild on my 2 ReadyNAS 3200's. This included replacing any drives with errors, upgrading the firmware to the newest version, resetting the device to factory defaults, then re-configuring the volume and shares.
Since completing this, I have noticed fewer instances of this error. It no longer happens at 'random', or when I'm running backups. This is an improvement.
However, there are still issues whenever the arrays complete a RAID scrub. The last time a scrub ran, my monitoring software registered 200-300 "storage is not accessible" events on the ESXi hosts. These stopped immediately once the RAID scrub finished. This seems to indicate that the arrays are not able to maintain consistent network connectivity while under the load caused by the scrub.
So far this flakey connectivity has not caused data loss or corruption in my environment. However, it means I have to hand-hold the environment whenever a RAID scrub is scheduled.
IMO, these units are not stable enough for a VMWare environment. I've had zero issues with my NetApp FAS2220 that is using the exact same infrastructure and is actually running a heavier load.
