[SOLVED] Changing cache drives

[steelrat]

Hi everyone,

 

I recently bought a second 1TB Cache drive to add to my cache pool, after the initial 500GB drive grew too small and I had already added another 1TB.

 

Now I wanted to add the second 1TB and move to raid1 have better data security and remove the 500GB thereafter.

 

As far as I've already read, I can add the second 1TB, wait for the cache balance to finish and then simply remove the old 500GB drive.

 

This is my current config:

Data, single: total=625.00GiB, used=608.64GiB

System, RAID1: total=32.00MiB, used=112.00KiB

Metadata, RAID1: total=1.00GiB, used=326.69MiB

GlobalReserve, single: total=138.88MiB, used=0.00B

 

My questions now would be:

Can I move forward as planned?

And would it make sense to upgrade to 6.9.0 before or after the cache changes?

 

best regards

You can but only after balancing the pool to raid1.

Cache replacement is broken in v6.9, add/remove should be OK, but probably best to use v6.8 since it's known to be working there.
