The thing is we can't reproduce this issue at all. If you can generate
a vmcore when the hung happened, then we can review which processes
are stuck.
Hi,
don't know if that be any of help, but I run below scenario with SATA
and NVMe drives. For me, the issue is reproducible on NVMe drives only.
Scenario:
1. Create R5D3 with native metadata
# mdadm -CR /dev/md/vol -l5 -n3 /dev/nvme[0-2]n1 --assume-clean
2. Create FS on the array
# mkfs.ext4 /dev/md/vol -F
3. Remove single member drive via "--incremental --fail"
# mdadm -If nvme0n1
The result is almost instant.
Thanks,
Mateusz
