I'm making some tryout before migrating my old Linux server to OMV 5 + UnionFS.
Config : Proxmox VM OMV5 with latest build, UnionFS plugin. System is cold backuped thanks to Proxmox everyday within 5minutes. One UnionFS named 75015001500 built with x3 old test HDD 750GB and 2x 1500GB (total 3750GB). The config works well and access within SAMBA works in minutes.
Now comes the test: I removed one HDD, the 750Go one physically and detach the reference from the OMV VM.
Of course OMV won't work anymore.
My goal is to make OMV works again without the 750go hdd, as my use case is that the 750GB is totally dead.
What is to be done to recover the unionfs share with only the data stored on the 2x remaining 1500GB drives please ?
