On the old server I used a USB Drobo unit to backup data.
In theory should be enough to connect the unit to the server to see it .. and in part is true, but there are some unexpected problems.
Drobom
It is necessary to install the drobom utility (part of the package Drobo Utils).
Because the version of Linux the only reliable way is from GitHub, installing the source and building it.
Drobo-utils is not anymore available as package from the distribution.
Once installed and configured there are mainly two useful commands (it is assumed the drobom command be in the path or be in the directory containing it) :
- sudo ./drobom status
- sudo ./drobom info
Status
The status command allows to see if everything is normal and the used capacity of the unit.
For example :
$ sudo ./drobom status
/dev/sdb /media/drobo Drobo 80% full - ([], 0)
Info
The Info command returns information about the unit configuration and status of each hard disk :
$ sudo ./drobom info

hoho! multiple partition types! Brave are we not?

So it is possible to regularly interrogate the unit and extract from the Info if one hard disk has problems and the remaining capacity of the unit.
