Hello Cephers,

 

I have an issue with OSD device mount on tmpfs with bluestore

For some occasion, I need to keep the files on the tiny bluestore fs (especially keyring and may be other useful files needed for osd to work) on a working OSD

Since osd partition is mount as tmpfs , these files are deleted once VM rebooted or even when umount

 

Is there a way to have a persistent storage for those files instead of tmpfs ?

I could copy them in another location and copy back once rebooted, but this seems very odd

 

Those files are generated on osd activation from information stored in LVM metadata. You do not need an extra external storage for the information any more.
