Hi Marco,
Sorry for the delay, yesterday was a busy day...
I'm posting this to the list too, it may be helpful to others.
Remenber, this procedure was for physical partitions and for resizing
Bluestore DB.
=== Cambiar/ampliar la partición block.db de Bluestore
1. Obtener la partición actual block.db: (BLOCKDB_PART)
ls -l /var/lib/ceph/osd/ceph-OSDID/block.db
2. Comprobar datos Bluestrore:
ceph-bluestore-tool show-label --path /var/lib/ceph/osd/ceph-OSDID
3. Obtener "Partition unique GUID" de la partición block.db:
sgdisk -i BLOCKDB_PART_NUM BLOCKDB_PART_DISK
4. Estudiar particiones del disco donde queremos crear la nueva
partición, para ver dónde crear la nueva partición
(BLOCKDB_PART_NUEVO_NUM, BLOCKDB_PART_NUEVO_DISK,
BLOCKDB_PART_NUEVO_START_POS)
sgdisk -p BLOCKDB_PART_NUEVO_DISK
5. Crear nueva partición
sgdisk --new=BLOCKDB_PART_NUEVO_NUM:BLOCKDB_PART_NUEVO_START_POS:+30GiB
--change-name="BLOCKDB_PART_NUEVO_NUM:ceph block.db"
--typecode="BLOCKDB_PART_NUEVO_NUM:30cd0809-c2b2-499c-8879-2d6b78529876"
--mbrtogpt BLOCKDB_PART_NUEVO_DISK
6. Recargar las particiones
partprobe BLOCKDB_PART_NUEVO_DISK
o bien
partx -u BLOCKDB_PART_NUEVO_DISK
7. Establecer permisos adecuados a la nueva partición
chown ceph.ceph BLOCKDB_PART_NUEVO_DEV
8. Parar OSD
systemctl stop ceph-osd@OSDID
9. Copiar datos de la partición vieja a la nueva
dd status=progress if=BLOCKDB_PART_DEV of=BLOCKDB_PART_NUEVO_DEV
10. Eliminar partición vieja y poner su "Partition unique GUID" a la nueva:
sgdisk --delete=BLOCKDB_PART_NUM BLOCKDB_PART_DISK
sgdisk --partition-guid="BLOCKDB_PART_NUEVO_NUM:PARTITION_UNIQUE_IDE"
BLOCKDB_PART_NUEVO_DISK
11. Recargar las particiones
partprobe BLOCKDB_PART_DISK
partprobe BLOCKDB_PART_NUEVO_DISK
o bien
partx -u BLOCKDB_PART_DISK
partx -u BLOCKDB_PART_NUEVO_DISK
12. Ajustar enlace a block.db en OSD
cd /var/lib/ceph/osd/ceph-OSDID
rm block.db
ln -s BLOCKDB_PART_DEV block.db
13. Ampliar de forma efectiva el block.db
ceph-bluestore-tool bluefs-bdev-expand --path /var/lib/ceph/osd/ceph-OSDID
14. Poner en marcha OSD
systemctl start ceph-osd@OSDID
15. Compactar OSD en caso de que haya spillover
ceph daemon osd.OSDID compact
Hope this helps...
Cheers

Hola Eneko,
I think this is everything I can offer in spanish except ordering an
orange juice :)
I would be interested to test out your commandchain on my testcluster.
Thanks again for your input. Will take a look at "Ceph bluestore db
resize".
Kind Regards
