Hi Alwin,

Thanx for the help.

I see now that I used the wrong wording in my email. I want to resize the
journal, not upgrade.

So, following your commands, I still sit with a 1GB journal:



oot at virt1:~# ceph-disk prepare --bluestore \
> --block.db /dev/sde --block.wal /dev/sde1 /dev/sda
Setting name!
partNum is 0
REALLY setting name!
The operation has completed successfully.
prepare_device: OSD will not be hot-swappable if block.db is not the same
device as the osd data
Setting name!

prepare_device: OSD will not be hot-swappable if block.wal is not the same
device as the osd data
prepare_device: Block.wal /dev/sde1 was not prepared with ceph-disk.
Symlinking directly.

Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
