Hello,
i found several pages on the net stating the specialdevice gets around 75% used per default, but this setting can be changed.
No one mentioned where this can be done, i only found one setting with 75 for l2arc, which, obviously, is something different.
Does anyone know more?
I also know, that you can't remove a specialdevice BUT you can add additional specialdevices, much like in regular RAID10 ZFS.
But can you also add a larger specialdevice (either to the vdev mirror or as separate vdev) AND then, after sync, remove the old specialdevice for additional space?
I would really appreciate some clarification as i've chosen some slightly to small ssds for the specialdevice and may run into the 75% limit soon.
Kind regards
Stephan
PS: This is a crosspost - i also posted to the national proxmox forum and tried to translate as good as possible. I'll share the answers in both threads, of course!
