Weezmo Posted February 21, 2019 Share Posted February 21, 2019 Hi I've been trying to workout errors by seaching around the forum for people already having experience this or similar, but after 2 weeks of apparently not being able to work this out myself I call upon the aid of the Unraid masters patrolling the forum. The gear: Z9PE-D8 WS 2 X E5-2670 128GB ECC DDR3 ram 3 X LSI 9207-8i Case: Inter-Tech 4U 4424 https://www.inter-tech.de/en/products/ipc/storage-cases/4u-4424 Disks are a mix-match between 8TB Ironwolves, 6 and 3 TB Red's and a single Toshiba 3TB disks are connected through the LSI Adapters since yesterday connected as 2 SAS to SAS backplane (8 Ironwolf Disks) 2 x SAS to sata breakout cables (rest of the disks), this was done to see if backplane was causing the issue or the >cheaply< bought sas cables What I've experienced these last 2 weeks: I have been getting a few millions of CRC UDMA errors over the past few days My parity sync is usually lying around 1.5MB/s sometimes topping at about 5.4MB/s yesterday i moved my disks around, replaced some sas to sas cables with some previously used sas cables from an old DL380 G6 and breakout cables for the rest of the disk Best Regards Weezmo tower-diagnostics-20190221-1447.zip Quote Link to comment
JorgeB Posted February 21, 2019 Share Posted February 21, 2019 Disk 18 is failing and needs to be replaced: 197 Current_Pending_Sector -O--C- 100 100 000 - 264 198 Offline_Uncorrectable ----C- 100 100 000 - 264 But since currently both parity disks are invalid, there's no way to rebuild, you can try to copy everything you can from that disk manually or use ddrescue.

Thank you for your answer I've used the "New Config" button under tools and taken out the drive "Disk 18" from the array and mounted it as its own drive share, so that i could move/copy data from it to the array. attempting to just move the files seems to trigger something on the disk that halted either the write speed to the array or the read speed from Disk 18. Copying the files from Disk 18 seems to work well however, keeping burst speeds at 200MB/s and shortly dropping to the 20MB/s range Maybe after the initial move over files (10/11 hours) I might be able to see whether or not it has improved the parity speed 😜 as I have yet to see after 20 hours of parity build even 1% complete Best Regards Weezmo tower-diagnostics-20190221-1645.zip Quote Link to comment
