Hi All,

 

Issues:

Cannot read/write to the array

Cannot stop the array after it is started

Cannot stop Parity Checks

 

Safe Mode without plugins works fine... which makes me think this issue is not hardware related... but I could be wrong.

 

I've run into a major issue whereby I am getting heaps of read errors.

 

Sequence of events.

- Changed Motherboard from Asus B450-i to  Gigabyte Z170XP-SLI-CF (AMD to Intel)

- Disk 5 was being disabled by unriad so I followed the rebuild proceedure in 'safe mode' twice to no avail.

- Changed out Disk 5 to a Seagate Iron Wolf I had spare.

- Moved Disk 5 from being plugged into the m.2 to 5 port sata adaptor

 

Adaptor being used:
Link - JMB585 M.2 To NGFF 5 Ports SATA 3.0 Adapter Card M.2 Key M SATA3.0 Expansion Card For

This turned to array to 'good'.

 

However, after booting up the OS I can access the shares for a minute or so but then I can no longer access them.

 

Troubleshooting:

- I can write to the flash drive 

- Syslinux config change:

append initrd=/bzroot nvme_core.default_ps_max_latency_us=0
But have since changed it back to 

kernel /bzimage
append initrd=/bzroot

- New SATA Data cable on the original Disk 5 Issue

- Recreated flash drive using myservers backup.

 

Background:

- Previously I was using an M.2 SSD as cache (previous motherboard had 2 m.2 ports).

Hence the syslinux change was made to try to resolve this.

Diagnostics attached.

 

Have ordered an HBA card but that wont arrive for 3 weeks.

JMB controller is bound to vfio-pci, delete /boot/config/vfio-pci.cfg and reboot.
