rowid_alex Posted May 24, 2021 Share Posted May 24, 2021 Hello guys, I just found my parity disk sdf has been disabled since midnight.

And I am not sure if I should stop array and to rebuild the parity disk with the same hard disk or not. Please kindly help check. Diagnostic file is attached. Thanks a lot!

trurl Posted May 24, 2021 Share Posted May 24, 2021 No SMART for parity in those. Check connections and post new diagnostics. Quote Link to comment

My understanding is that since the disk is disabled so SMART is not available. Should I restart the array to get SMART back? Quote Link to comment

JorgeB Posted May 24, 2021 Share Posted May 24, 2021 SMART is still available for disable disks, but parity dropped offline, so there's no SMART, you should check/replace cables to rule since that looks more like a connection problem and them and post new diags. Quote Link to comment

Understood. I will check the cable then. Thanks for the explaination. Quote Link to comment

Hello I reboot the server and this time parity disk has SMART data. I found flag 0x000a UDMA CRC error count added one permanently. But everything else seems fine. 0x06 0x018 4 1 --- Number of Interface CRC Errors Please kindly suggest what should I do to enable the disk.

rowid_alex Posted May 24, 2021 Author Share Posted May 24, 2021 BTW, I checked the location of the disk and it is connected to the SATA port on the motherboard directly. So it doesn't seems to be a cable issue...unless it happens the next time I think. Quote Link to comment
JorgeB Posted May 24, 2021 Share Posted May 24, 2021 13 minutes ago, rowid_alex said: UDMA CRC error count added one permanently That is a connection problem, usually a bad SATA cable, and consistent with how the disk dropped, so you should replace that before re-syncing parity.
