Cache Drive Not Mountable No File System

[luisv]

I added two data drives to my system as well as an LSI 9211-8i controller.  I moved my 2 cache drives to make space for the two data drives, but I kept the cache drives connected to the same SATA ports on the motherboard.  When I booted up the system, one of the cache drives was recognized, but the second was not.  It shows as Unmountable: No Files System.  Not sure what to do next as the only option I see below, is to format the drive.  I have a backup of the Appdata folder from this past Sunday.  Any help is appreciated.

Sorry, I replied on the other thread, this is basically a duplicate thread.  I can delete this one if necessary.

One of your cache devices is corrupt, reported as missing event though it's assigned:

And looks like your were using raid0 or single profile, since it won't allow mounting with a device missing.

 

If there's no important data there just format, if there is see here to try and recover:

Just dockers and VMs, I have a backup from this past Sunday.   I guess it's just quicker to format and restore?  Then update the dockers as a few had updates since the weekend.  

[JorgeB]

If all cache data is backed up (including the vdisk(s) if they were on cache) it should be faster, for dockers you only need to have the appdata, docker image can (and should) easily be re-created.

[luisv]

Yes, I didn't exclude any directories and the vdisks were on the cache.

Restore is complete, sorry for the silly question as this is the first time I've had to do this, but how do I get my dockers an VMs back?  Both tabs are blank.   

[JorgeB]

For the dockers just re-add them from my templates or using CA's previous apps pointing to the existing appdata location.

For the VMs you need to stop the service, restore libvirt.img overwriting the existing one, restore the vdisk(s) and restart the VM service.

Thanks for all the help!
