Me and a couple of friends have been running our own root server for literal decades, and the hardware is getting a bit long in the tooth, so time for an upgrade.

The question right now is which storage configuration to pick, it's mostly a choice between RAID0-ish(*) over 2 x 8 TB disks or RAID5 over 3 x 4 TB. What does the fediverse think?

(*) not a live RAID0, but a nightly mirror from main disk to backup disk

#selfhosting #linux #sysadmin

2 disks, mirror
30%
3 disks, RAID5
25%
Something else?
45%

@floe #ZFS RAID-Z[23]. Else, ZFS mirror.

@ax6761 I admit I've never touched ZFS - from what I can see in the nice primer here (https://blog.victormendonca.com/2020/11/03/zfs-for-dummies/), RAIDZ-2 would require at least 4 disks, do you think RAIDZ-1 would also be an option or are there some pitfalls I'm not aware of?

@floe Tolerance for failure of only 1 disk is not enough & anxiety causing.

If you do go with only 1-disk parity (ZFS or otherwise), you would need to be proactive about disk replacements on signs of errors, and should have 2-3 spare disks on hand.

Regardless, you would also need to arrange for backup(s).
