[system non operational] KVM NS8, resized qcow now I cannot see the cluster admin!

I found an older thread made by… me (!!!), that I had this issue on another server!
Disk space issue NS8 doesn’t even start services! - Support - NethServer Community

…maybe the server should alert admin in a more dynamic way that something is wrong?
I mean, backup failing (initially just one of the backup sources, the rest ok), doesn’t really alert you that the whole server is in a spiral of death!

IN ANY CASE, to the problem at hand… I followed a similar path to that thread that solved the issue back then, but it did NOT solve anything in this case!
My system is still dead.

I did “growpart /dev/vda 5” (the partition that seems to have been full).

I rebooted the vm… initially for a few seconds I DID get a cluster admin screen, I went on to see the disks (I don’t remember where, as I don’t have a working cluster admin working now) and I happened to see “no disk” where the three partitions should be enumerated!
After that, cluster admin went down again!!!

I did lsblk in the console and I DO see vda5 now has the new size (62.9G from 39.somethingG).
But… no go!
What happened?
…also not that vda5 seems to show two mountpoints (this was also before I resized anything) and I don’t know if this is correct:
/var/lib/containers/storage/overlay
and
/
(which / is the only I expected to see)

Help bring my server in operation again please.
