Yeremyah777 Posted May 3, 2019 Share Posted May 3, 2019 Okay... so I had a drive start to go bad. I was running on an old AMD FX 9590 CPU on a Sabertooth Motherboard. I have 10 drives with 2 Parity Drives. I moved the whole system over to a dual Xeon x5670 system with 32GB of ECC Memory on a SuperMicro X8DTH Motherboard. I have a 1070 and a 1070ti GPU. All of this just to run Plex and a VM. I also have 2-240GB SSDs for cache. All of this power, and when I started the new system, it detected an error on disk 1. So I bought a new 8TB HDD and replaced the disk and started the parity/sync rebuild. All of this information and diagnostics info to ask why the heck my rebuild is this slow? I have more than enough processing power, and the speeds of all of the drives should be fast enough. So what's the issue? server-diagnostics-20190503-0217.zip Quote Link to comment

You might want to check all cabling to this drive. Quote Link to comment
JorgeB Posted May 3, 2019 Share Posted May 3, 2019 Your 10 port SATA controller is in reality a 2 port controller with 2 SATA port multipliers, this is very bad news both for performance and reliability, suggest you get an LSI HBA instead. Quote Link to comment

Ouch yes that is a huge bottleneck for this system. Quote Link to comment

I have 2 of these (Gigabyte GC-RLE086-RH LSI 1068E HBA card 8-port SAS /SATA PCI-E array card=3081e) enroute to me. will these be good enough, or should I go for something like this? (LSI SAS 9211-8i 8-port 6Gb/s PCIe HBA RAID SATA Controller card=M1015) Quote Link to comment

Yeremyah777 Posted May 3, 2019 Author Share Posted May 3, 2019 (edited) Oh lame... I didn't even see that. Are there any HBA cards that you would recommend since i have 2-10TB drives, 1-8TB drive, 4-4TB drives and a 3TB drive? Edited May 3, 2019 by Yeremyah777 Quote Link to comment
JorgeB Posted May 3, 2019 Share Posted May 3, 2019 Any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed. 2 Quote Link to comment
Yeremyah777 Posted May 11, 2019 Author Share Posted May 11, 2019 Okay... here I am a week later, $100 spent on some newer tech, flashing the Mobo SAS to IT mode as well. and now I have the same issue. It's now 5.9MB/s and hits as high as 8MB/s, but I think this is still too low. I openly admit that I am VERY new to this, bu love this software solution and appreciate any advice I can obtain to tune this system to perform at peak performance. dunham-server-diagnostics-20190511-0436.zip Quote Link to comment
Solution JorgeB Posted May 11, 2019 Solution Share Posted May 11, 2019 There is no SMART info for any disk, go to settings -> disk settings and reset SMART options, alternatively delete /boot/config/smart-all.cfg and reboot, then grab new diags. Also a good idea to update the firmware for HBAs, two are very old and another is running a release with known problems. Quote Link to comment
