SnapRAID and BTRFS both support adding disks.
On BTRFS you simply use the new space or rebalance the pool to use the new disk properly.
On SnapRAID the next scan will add the disk to the parity drive contents.
For low-cost home usage, it is much much more cost effective to only buy single disks and start with small pools over buying large pools or even replacing entire pools.
- michaelmrose 9y agoSince I presume you have verifiable backups of your pool couldn't you just remake the pool with the increased number of disks and copy back to it?
- tscs37 9y agoRecovering from my current backup solution is expensive, the additional cost is not worth it. Remaking the entire pool is also a hassle and incurs unnecessary downtime. Additionally, not all data is backed up, which I will loose, as this is not important data, it's okay to loose during a house fire, but not just for resizing the disk. Lastly, this operation would likely take a long time, days probably, I'd rather just be able to just ram in another disk and be done with it.
- michaelmrose 9y agoI had assumed you would have a second array as backup for the current pool ensuring zero data loss and easy backup. This would seem to be optimal. Remote backup is obviously a good thing to have too.
- tscs37 9y agoSuch a solution is extremely expensive and inefficient for a home setup.
- michaelmrose 9y agoAll things considered your house will probably never experience a major disaster remote storage has got to be many times more expensive.
