Guys,
Presently my main storage server is run on Centos 8 using Webmin and commandline utilities to serve up about 40TB of disk space in a RAID6 config. I am evaluating moving from this to Truenas.
As a way of putting my toe in the water with Truenas - i have a secondary system - the sole job of this system is to provide a backup of media from the main storage box - so currently this box is woken up every day through a cron job on the main system and WOL.
Once it is up and running it runs a script using RSYNC to replicate any changes from the live media system to local storage on this box.
As this is ONLY a backup box (we also send photos and home videos etc off-site) i use RAID 5 disks on this system - my practice in the past has been to purchase newer disks for the live storage system and then migrate the oldest disks from the live system to the backup system as additional storage is required.
I have up until now use LVM and RAID5 on this system with XFS on the actual partitions that are presented.
I think i have my head around the ZFS terminology etc so would assume that when i built this box with TrueNas i would set the drives up as RAIDZ1 ?
Does everything HAVE to be ZFS or are there other filesystem options ?
As the drives are different sizes (i have for instance at the moment 8 x 4TB WD Red, 4 x 6TB WD RED and 6 x 3TB WD ReD) on the system (i use multiple LSI controllers flashed into IT mode) would i just create a pool on each of the like sized drives and then add the drives to them ? If so is there the ability to "span" pools as LVM enables me to do on Linux and present all the storage as one entity ?
If i retire another 6TB drive (which will be coming up on the main server) - is it a simple task (or even possible) to add this into the pool with the other 6TB drives and expand the storage or do i have to blow away that pool and start again ?
thanks for the help
Craig
