These appear to be in a single raid 1 at this time. We cannot really add a
single disk in, without breaking the entire redundancy aspect of the raid/data
arrays.
So I would recommend that we upgrade by adding two more disks to each from our
on site spares, of which we have 38 Intel 320 Series SSDSA2CW300G3 2.5" 300GB.
These are the identical model. I suggest we add in two more per system, and
then reinstall the system from a single raid1 array into a 4 disk raid10 array.
We could do this upgrade to one system and have it come fully back online
before installing in the second.
The only costs I see is the rolling maintainance/reinstallation of each system
(leaving one of the two in full service at all times). We have 38 Intel 320
SSDs, as they are an older model spare we do not use in our newer SSD based
deployments.
@Smalyshev: Would you please review my above suggestion and provide feedback?
If you agree, we can assign this task to @Mark to approve the use of allocated
spares for upgrades. (The use of spares for repair is automatic, but stealing
spares for upgrade requires we ensure its acceptable.) If you do not agree,
please assign this back to me with your corrections.
Thanks!
