Hey guys i'm having the weirdest issue and i'm hoping someone can help.

 

First off im using an older 24 - bay supermicro server with 3 x AOC-SAT2-MV8 cards in it and i already have 2 other 3TB hard disks running just fine in this setup.

I bought some refurb hard disks off of ebay (newegg 55$ 3TB HGST) and as normal i put them into their caddies and pushed them into the hot swap bays and bam unraid locks up with a kernel panic.

 

Upon restart i get a kernel panic on boot...i tried with all 3 new drives inserted....tried putting in one at a time. All has the same issues.. as soon as i remove them all boots up no problem and chugs along as usual.

 

At first i was thinking maybe a compatibility issue with the AOC-SAT2-MV8 cards as they are older but i have a WD and SG 3tb disk already in the array with no issues...... any help would be greatly appreciated

One thing to check is whether the PS is being overloaded when you add more drives onto your system.  Overloaded PS's do many weird things...

i don't think so cuz i just pulled like 8 drives and tried to reboot and got the same kernel panic and crash at boot

This is likely the problem, there are known issues with these controllers and newer devices, not related to size, e.g., I tried some time ago and got kernel panics with small SSDs.

It's not all devices, it's some recent devices.

Do you know if there's any other pci-x cards that have better support for newer hard drives?

 

I guess i could update to a newer motherboard cpu combo to get PCIe .....but i'm not sure what the compatibility with the backplane would be like... this backplane has 1 sata connector for every disk not a SFF-8087 connector.

 

Just don't wanna spend a bunch of money for it to be incompatible....

AND i found a workaround for this by just plugging the disks directly into the 6 sata boards on the motherboard.... thanks for the input and help troubleshooting!

Pci-x is long dead, so not many alternatives, when you run out of the onboard SATA ports for the new devices consider upgrading to a PCIE board.
