Cartierusm Posted April 5, 2021 Author Share Posted April 5, 2021 Ok I restarted. Then used binhex krusader to transfer files from disk3. This morning I had a "Unraid Parity Disk SMART Health [199]:04-04-2021 20:48 Warning [Tower] - udma crc error is 68 WDC-yada yada yada" this is parity disk 1. So what does that mean after doing all those parity checks. Is the drive no bueno? Also included the diag file. tower-diagnostics-20210405-0810.zip Quote Link to comment

You can acknowledge those by clicking on it in the Dashboard. It will warn you again if those increase.

And an increased count from before so might be worthwhile to check those connections. Power and SATA, both ends, including splitters. Change SATA cable if you have a spare. Quote Link to comment
Cartierusm Posted April 7, 2021 Author Share Posted April 7, 2021 Ok I hate to be that guy, but what's the best way to take that disk 3 and reformat it so that my system/parity is intact when I'm done? I read the wiki, but seems like every time I do something there's 50 ways to do it. Quote Link to comment

I'd copy the data instead of moving it, much faster, and you can verify the copy is complete and intact before you format the drive. Unraid parity is realtime. Any write operation to a data disk in the parity array updates parity at the same time. Format writes an empty filesystem to the disk. That write operation is treated just like any other with parity being updated at the same time. Just in case you didn't get it, once you format that disk any data it had on it is gone. Did you copy it elsewhere? 52 minutes ago, Cartierusm said: I read the wiki https://wiki.unraid.net/UnRAID_6/Storage_Management#Converting_to_a_new_File_System_type https://wiki.unraid.net/UnRAID_6/Storage_Management#Changing_a_File_System_type Quote Link to comment

Reformatting a drive is covered here in the online documentation accessible via the ‘manual’ link at the bottom of the unRaid webGUI. Quote Link to comment
Cartierusm Posted April 7, 2021 Author Share Posted April 7, 2021 Thanks. Already completed!! We're up and running again. Also, I switched the bay that parity was in and so far so more crc errors. Quote Link to comment
