@softraid-support Connected another monitor via HDMI, direct to the MacBook. ThunderBay connected direct. Eject drives manually. Disconnect cables. Open lid. Kernel panic in about a minute.

I have to figure out why I am not seeing this. I will work on this in the evening again. I may query you if I don't see it.

@softraid-support One thing I notice is if I eject a disk (ThunderBay), cable stays connected for about an hour, disconnect, SoftRAID still reports the disks not properly ejecting.

@mcvosi 

Thats a small clue. But it is probably Time Machine hanging to the volume causing the disks not ejecting message.

@softraid-support Should I try disabling Time Machine and see if I can eject without the KP?

@softraid-support Still crashes unfortunately. I went ahead and deleted my volume to see if there was any combination of RAID levels and stability.

Tips for a set of 4 drives? RAID 4?

Maybe this is my issue all the time:

Encryption not supported at this time. There is currently an issue with macOS that can cause kernel panics on encrypted SoftRAID APFS volumes. We are unable to support encryption until this is addressed in macOS.

I did not realize you were erasing the volumes as encrypted. Yes that can cause your panics. We know Apple engineering is investigating this.

@softraid-support Yep. OK, will backup unencrypted and see how it goes.

@softraid-support Even though no encryption on TM backups I just had a KP like usual.

@mcvosi 

Is the panic always during a backup?

@softraid-support No, happens after about a minute of opening the lid.
