giantrobot Posted October 14, 2019 Share Posted October 14, 2019 Hi there, I've got a server that's been running fine for about 8 weeks with no problems. I accidentally powered it off three days ago, and finished a successful parity check upon restart (with errors detected). That being resolved, I put in two 8TB WD Red drives into the array and started preclearing them this morning, only to come down with errors on one of my 10TB drives, taking it offline. Is there anything I can do to not replace the 10TB drive, or do I at the very least need to preclear it again for use? If I do need to replace it, once the 8TB drives come online, is there a way to move stuff around so I can evacuate enough data off of that 10TB drive and replace it with one of the 8TB ones?

trurl Posted October 14, 2019 Share Posted October 14, 2019 On mobile now so can't look at Diagnostics. Please wait for advice. Quote Link to comment
JorgeB Posted October 14, 2019 Share Posted October 14, 2019 Disk dropped offline so there's no SMART, and although I'm also on phone and not so easy to check diags looks like a controller problem, you're using an Asmedia controller with a port multiplier and those are known to have issues and are not recommended, suggest replacing it with an LSI HBA.

JorgeB Posted October 14, 2019 Share Posted October 14, 2019 Forgot to mention that you'll need to reboot/power cycle the server for the dropped disk to come online, then post new diags so we can check SMART but most likely it's fine. Quote Link to comment

Looking now at the diags again, disk4 also dropped offline, not surprisingly it's using the same controller. Quote Link to comment
JorgeB Posted October 14, 2019 Share Posted October 14, 2019 Also two port Asmesdia controllers are fine, 6 and 10 port Asmedia controllers use port multipliers and those are nothing but trouble. Quote Link to comment

JorgeB Posted October 14, 2019 Share Posted October 14, 2019 (edited) Can't think of any good option, you could cut/dremel the PCIe slot to fit an x8 LSI. Edited October 14, 2019 by johnnie.black Quote Link to comment

Those are not recommended at all for v6, they worked OK with v4/v5. 1 Quote Link to comment
giantrobot Posted October 15, 2019 Author Share Posted October 15, 2019 ok, i finished my one good preclear, removed the extra two drives, and restarted the machine. here are the latest diagnostics. all smart reports claim PASSED -- maybe everything was just the controller being overloaded and all is good? if so, how do i put it back into operation? do i follow the procedure to unassign/reassign it to the array and rebuild onto itself? voltron-diagnostics-20191015-0038.zip Quote Link to comment

With those controllers it will happen with normal use, and a good controller can't really be overloaded, you should be able to use all ports at once. 6 hours ago, giantrobot said: if so, how do i put it back into operation? do i follow the procedure to unassign/reassign it to the array and rebuild onto itself? You can, but if you don't replace that controller it will likely happen again sooner or later. Quote Link to comment
