zzgus Posted April 21, 2017 Share Posted April 21, 2017 (edited) Today I have seen that one of my discs is lost. I don't clearly see what had happened: One disc with errors (Disc 5) One disc lost (Disc 6) One disc with errors (Disc 7) with one share that is not shown on my shares tab. I can see the share on MAIN tab on "browse /mnt/disc7" but there is no share on SHARES tab. What must I do? Attached diagnostics file. Thankyou Gus unraid-media-diagnostics-20170421-1727.zip Edited April 21, 2017 by zzgus Quote Link to comment
JorgeB Posted April 21, 2017 Share Posted April 21, 2017 Do you have any disks connect on the Marvell controller (first 4 white ports)? Quote Link to comment

Don't tell me I have made the same mistake another time !!! Some days ago I made changes to the disks on new cages but didn't remember had changed sata cables since last time. Will check. Do you see on the diagnostics file that those discs are connected to the marvel? Thankyou Gus Edited April 21, 2017 by zzgus Quote Link to comment
JorgeB Posted April 21, 2017 Share Posted April 21, 2017 Didn't check the logs before, still not sure since the beginning of the syslog is missing, but looks like a controller crashed, possibly the Intel SCU controller (the last 4 blue ports) Quote Link to comment

JorgeB Posted April 21, 2017 Share Posted April 21, 2017 Best would be to reboot and post new diags. Quote Link to comment

zzgus Posted April 21, 2017 Author Share Posted April 21, 2017 I have rebooted the system, changed sata ports and power but I continue to have thisc 6 miss. Attached diagnostics. As I don't use disc 7 (almost empty) whats the way to use it as disk 6 and recover it's contents from parity? is it possible?

JorgeB Posted April 21, 2017 Share Posted April 21, 2017 (edited) All three affected disks are on the SCU ports, so I believe I was right and that controller's driver crashed, hopefully it was a one time thing. Disk6 is not missing, it's just disable, unRAID disables the first disk it can't write to when a controller crashes (or the first 2 if using dual parity), disk looks fine so you should rebuild to the same disk, to do this you need to stop the array, unassign disk6, start the array, stop the array, reassign disk6 and start the array to begin the rebuild.

zzgus Posted April 21, 2017 Author Share Posted April 21, 2017 As always @johnnie.blackmany thanks for your quick response. Gus Quote Link to comment
zzgus Posted April 22, 2017 Author Share Posted April 22, 2017 @johnnie.black one last thing. I have a spare single socket supermicro X9SRi-F motherboard. http://www.supermicro.com/products/motherboard/Xeon/C600/X9SRi-F.cfm As I no longer need the dual socket ASROCK motherboard I'm using now, do you think the supermicro will be a better option?

JorgeB Posted April 22, 2017 Share Posted April 22, 2017 Difficult to say but I would guess that as long as the Asrock Marvell ports are not used stability should be similar. Quote Link to comment
zzgus Posted May 15, 2017 Author Share Posted May 15, 2017 @johnnie.black Well, mmmm not yet a month and another time some errors on disk 6 a before. Attached diagnostics to see if there's something new. I don't know what I will have to do with those "persistent" crashes :-( Thankyou Gus unraid-media-diagnostics-20170515-2137.zip Quote Link to comment
JorgeB Posted May 15, 2017 Share Posted May 15, 2017 (edited) Symptoms are the same, but happening again to the same disk may not be a coincidence, I would swap that disk with another from the main Intel controller, rebuild it, and in case it happens again you can see if the problem follows the disk or stays with the controller.

zzgus Posted May 16, 2017 Author Share Posted May 16, 2017 @johnnie.blackbad news. I did a rebuild with no luck, some read errors. (rebuild cancelled I think unraid showed on notifiactions tab) I will remove this disc for safety. Gus Quote Link to comment
JorgeB Posted May 16, 2017 Share Posted May 16, 2017 If the rebuild failed on the main Intel controller it's probably a bad disk despite the healthy looking SMART. Quote Link to comment
