Issue defragmenting partition after conversion to dynamic disk

I have a disk had two basic partitions. I had run Defraggler on both partitions multiple times. Today I deleted the first partition and replaced it with a striped volume. The second partition was automatically converted from basic to dynamic, but I didn’t make any manual modifications to it.

Now when I try to defragment the second partition, the operation hangs indefinitely at status “Defrag Started”. Pressing Stop has no effect, and a Defraggler process remains after closing the window (consuming roughly 25% CPU). I’m reluctant to enable boot time defrag in case it hangs there too.

I hadn’t had any issues with the partition outside of Defraggler, but just in case I ran a thorough chkdsk (chkdsk /f /r /x /b) which passed without any issues. That was after rebooting.

The second drive that’s part of the striped volume has two additional partitions, and I was able to successfully defragment one of them.

I actually have very little data on the problem partition, so I may just copy it elsewhere then delete and recreate the partition. But I was wondering if there’s anything I can do to troubleshoot first.

Defraggler version: 2.22.995 (64-bit)

Windows Edition: Windows 10 Pro

Windows Version: 21H1

OS Build: 19043.2130

I ended up just deleting and re-creating the partition. Defragmentation now works properly.
