Hello everyone,

i got a littel problem. One of my harddrives has many erros and was stopped by unraid. My idea was to exchange it with an SSD, because i want to slowly change all Drives to SSDs.

 

My Drive-Set up:

1. 8TB WD Red - Parity Drive

2. 4 TB Ironwolf

3. 4 TB Ironwolf

4. 4 TB Ironwolf (faulty)

 

2x 2TB NVME SSD as cache.

 

I bought a two 4TB SSDs to replace the faulty disk and add another 4 TB. Now Unraid tells me the SSD is too small and i can't rebuild the array. I read here that i can't change form hdd to ssd for some reasons.

 

My idea was to add the SSD as drive 5 and copy alle the data from dirve 2 or 3 to it and then use drive 2 or 3 to rebuild the faulty hdd. Is that a valid solution and if how can i achive that.

 

I want to avoid buyin another 4Tb hdd.

 

Looking forward to some advice

Unraid won't usually allow going from a HDD to an SSD of the same capacity, because the SSD will have a slightly smaller partition, and because of that, it will be considered smaller them the previous device, you can format and mount the SSD with UD, copy everything from the old/emulated disk there, then do a new config with the SSD and re-sync parity 

Thanky you,

stupid question. How do I do a new config and remove the old one. Will all the shares still work and all the docker container still work?

Right now I am copying everything.

SSDs in the parity array cannot be trimmed, and can only be written at parity speed.

Yes, if the SSD has all the same data as the disk had.
