Disk Utility has had several bugs when touching a disk formatted by SoftRAID

Just to be clear - this isn't really a "Disk Utility" issue per se, as Disk Utility is really just a GUI, right? The panic is occurring at the kernel level, ie: com.apple.iokit.IOStorageFamily. When you are reporting these issues to Apple, I'd recommend generating core dumps from the kernel panic and sending those along with the bug report. https://developer.apple.com/library/archive/technotes/tn2004/tn2118.html

Best is to "Zero disk" with SoftRAID, and see if that avoids the issue

For the zero disk workaround, will the first/last 100 option be sufficient or do I have to zero the whole device (which takes a long time)?]]> Investigating Problems with Disks bry2k https://forums.softraid.com/investigating-problems-with-disks/kernel-panic-initializing-ssd/#post-3089 Kernel Panic initializing SSD https://forums.softraid.com/investigating-problems-with-disks/kernel-panic-initializing-ssd/#post-3088 Mon, 07 Jan 2019 16:50:32 +0000 Investigating Problems with Disks SoftRAID Support https://forums.softraid.com/investigating-problems-with-disks/kernel-panic-initializing-ssd/#post-3088 Kernel Panic initializing SSD https://forums.softraid.com/investigating-problems-with-disks/kernel-panic-initializing-ssd/#post-3085 Mon, 07 Jan 2019 05:29:03 +0000 You encountered an OS X bug that causes the kernel panic. We have no control over Disk Utility. Am I correct in inferring from your reply that this is a known issue to you? Is there something specific to my configuration that causes this, ie, the OWC Thunderbay6, or the OS version, or SoftRAID version, etc? The panic log shows this: 0xffffffa7570cbfa0 : 0xffffff800141e9c6 Kernel Extensions in backtrace: com.apple.iokit.IOStorageFamily(2.1)@0xffffff7f820e4000->0xffffff7f8210bfff com.softraid.driver.SoftRAID(5.7.2)@0xffffff7f82114000->0xffffff7f8214ffff dependency: com.apple.iokit.IOStorageFamily(2.1)@0xffffff7f820e4000 Since SoftRAID is mentioned in the backtrace after attempting an initialize in Disk Utility, I assumed SoftRAID is at the very least involved in the cause of the kernel panic. Can you elaborate further as to what is happening here?

We will be supporting APFS in SoftRAID version 6. We are working on it, but it is a major project. Note at at the present time, APFS volumes are significanty slower than HFS. On SSD volumes, it is about 30%. On HDD's about 50%. So you may want to stick with HFS for now, if this is a scratch/editing volume.

I understand. My primary interest in using APFS was for experimentation, and a volume dedicated to scratch data best serves that.
