Error Exceeds maximum number of slabs supported

Hi all,

If I try to create file system on VDO device I receive error:
Exceeds maximum number of slabs supported
After analyze I identified the problem in CentOS 7 and in physical block device larger than 16TiB, see e.g. here:
http://136.243.53.213/rhel8.0/x86_64/rh ... index.html

Is it posible to create VDO device fully from CLI per command and parameter:
# vdo create \
--name=vdo1 \
--device=/dev/sde \
--vdoSlabSize=32G
?

Or exists another solution?

Thank you.

Hi, thank you for your question. Unfortunately, CLI is the only way to create a VDO device for now.
