RAID 0 to RIAD 5

[tmacka88]

Hey just a question about RAID before I jump into setting my NAS up just wondering if you can set up a volume with 2 HDD's in striping as RAID 1, and then say later down the track can you add another hdd and set it up into RAID 5 without deleting/reformatting the already 2 ZFS HDD's set up in RAID 1.

Or do you have to start again and have 3 HDD's and creat the volume as RAID 5, from the start.

Thanks.

Hi tmacka88,

You need to start again with all 3 drives.

Yeah, better to find out now than after you have 4GB of data and want to switch from raidz1 to raidz2 ;-)

what about if you have 3 HDD set up in RAID 5 can you add more HDD's keeping them all in one volume. Or do you have to set up a new volume every time you add HDD's. If you have to add a new volume every time is there a way of sharing them so when a computer connects to your share that it only sees one massive hdd so you can just keep adding more HDD's but without having to search into share 1 share 2 etc for different data?

Hi tmacka88 - Take a look in the FAQ in my signature (1st FAQ link). There's a question there about adding drives with several links that explain different ways of adding drives and what works and doesn't work. It's a common question with a detailed answer.

You can make them appear as one share though.
