I recently added a Supermicro CSE-836BE1C-R1K03JBOD to our FreeNAS 11.2 system. This JBOD is chained using two SFF-8644 cables to an identical JBOD which has been working flawlessly for 3 years. The older JBOD in turn connects to an LSI SAS 9300-8e HBA, also with two SFF-8644 cables . I am including sas3flash -list output below.
My problem is that I am getting errors on this new JBOD, like this:
(da16:mpr0:0:49:0): WRITE(10). CDB: 2a 00 60 52 4f 10 00 00 40 00 length 32768 SMID 503 terminated ioc 804b loginfo 31120303 scsi 0 state c xfer 0
(da16:mpr0:0:49:0): WRITE(10). CDB: 2a 00 60 52 4f 10 00 00 40 00
(da16:mpr0:0:49:0): CAM status: CCB request completed with an error
(da16:mpr0:0:49:0): Retrying command
There appears to be no SMART errors so I am thinking that this is a cabling issue and I have ordered new cables to test this theory.
Since everything has worked well until now, it occurs to me that I have no experience in downsizing. Hence my questions: can I unplug the new JBOD without disrupting other FreeNAS services? Do I need to export pools residing on the JBOD first? Can I swap one cable at a time with no downtime at all?
If you think it is not a cabling issue, other ideas are very welcome.
Thanks!
