  • How often do you change your storage setup? I’ve configured everything once like 5 years ago and haven’t touched it since. I can add larger disks in pairs and the Synology does some LVM-/mdraid-magic to add the newly available free space as RAID1 until I add a third larger disk and it remodels it to RAID5.

    How do you handle parity with MergerFS? Or are all your storage partitions mirrored?

    Hard drive storage is pretty cheap.

    Not really - especially, if you’re looking for CMR drives. And any storage increase needs at least 2 disks with basically no (ethical) way to get any money back for the old ones.



  • Rebuilding parity requires processing power.

    That shouldn’t be an issue with any NAS bought in the past decade.

    the rebuild stresses the drives

    You can tweak the parameters so the rebuild is being done slower. Also, mirroring a disk stresses the (remaining) disk as well. (But to be fair, if that one fails, you’ll still be able to access the data from the other mirror-pair(s).)

    It all results in management overhead

    I’m not seeing that. Tweaking parameters is not necessary unless you want to change the default behaviour. Default behaviour is fine in most cases.

    In comparison […] RAID is a headache.

    Speak for yourself. I rather enjoy the added storage capacity.
