Failed preloading extblkdev plugins, libcap depedency isn't specified?
Added by Rongqi Sun 11 months ago.
Updated 4 months ago.
Description
When deploy osd in multi-sites cluster, journal shows 'preload extblkdev plugins' (screenshot in attachment)
And after analysis, I found the reason is that 'libcap' versions are different in every node. And 'extblkdev' module is added in https://github.com/ceph/ceph/pull/46037, actually it lacks of a thing like 'version requirement' in spec. Not sure which version should be assigned.

Definitely not RBD, I'm moving this to RADOS as the pictures don't make the source of the error clear but OSDs definitely fail to start.
As as workaround maybe you could set osd_extblkdev_plugins to empty.
- Status changed from New to Need More Info
If the osd_extblkdev_plugins tuning helps, please let us know!

I had the same issue. Setting osd_extblkdev_plugins to empty doesn't help. I'm using centos 8 and libcap version is 2.26. After upgrade libcap version to 2.48, the osds started.
Hi Jianyun!
It's really weird that emptying the configurable doesn't help.
Would it be possible to have an OSD's log with verbosity bumped
up (debug_osd=20)?

We are seeing the same issue. setting debug_osd=20 does not add much more information. (unless i did it wrong?)
I'm guessing this happens on any Centos 8?
I'll have to figure out how to upgrade libpcap if that was a workaround

Edit: "dnf upgrade libcap" did indeed fix it and allow the OSD to start up.
