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
