[OmniOS-discuss] OmniOS backup box hanging regularly

[Hildebrandt, Bill]

It's a 4U direct-attached backplane . . . not an expander.  Each drive requires its own connection.

The zdb -bbccsv of my exported pool just finished and without error this time.

Dump is still available if you would like to review it.

SATA disks attached to a SAS expander (this is the SAS846TQ, an expander, right?) are known to be a dangerous deployment.  SATA doesn't have the reporting capabilities SAS does, and many SAS expanders don't relay SATA well enough.

We do not support paying customers who deploy like this.

FYI,
Dan
