Could it work importing the local filesystem as a Posix FS one?
just trying with a not critical one, with these parameters (the same ones
used before in /etc/fstab):

path: /dev/mapper/vgdata-data
VFS Type: ext4
Mount Options: defaults,discard

I get error related to sanlock daemon:

open error -13 EACCES: no permission to open
/rhev/data-center/mnt/_dev_mapper_vgdata-data/13dc30ad-6e14-4c7a-9b0f-68ebb2da8af4/dom_md/ids
check that daemon user sanlock 179 group sanlock 179 has access to disk or
file.
s1 open_disk
/rhev/data-center/mnt/_dev_mapper_vgdata-data/13dc30ad-6e14-4c7a-9b0f-68ebb2da8af4/dom_md/ids
error -13
s1 add_lockspace fail result -19

Currently I have:

# id sanlock
uid=179(sanlock) gid=179(sanlock)
groups=179(sanlock),6(disk),36(kvm),107(qemu)

# ll -d
/rhev/data-center/mnt/_dev_mapper_vgdata-data/13dc30ad-6e14-4c7a-9b0f-68ebb2da8af4/dom_md/ids
-rw-rw----. 1 vdsm kvm 0 Mar 12  2021
/rhev/data-center/mnt/_dev_mapper_vgdata-data/13dc30ad-6e14-4c7a-9b0f-68ebb2da8af4/dom_md/ids

Thanks
