[filesystem for raid5]

Sound a bit strange to put ZFS on top of RAID5, since ZFS has raid feature : RAIDZ

Thanks for reply. I was talking about raid5 or raidz1. The idea is to have only one drive for parity.

Using ZFS on ARM is still a bit early days and requires a bit of tuning, therefore you need to understand ZFS a bit better than just on surface. For that you need to allow yourself some time to play around with it.

I already figured it out. I do have experience in ZFS on x86. But I decided for myself that I can not use ZFS (or btrfs) on ARM and feel safe for data at the same time. Will wait and see. I'm sure that this will change soon.

If you are looking at checksuming / scrubbing feature just on small portion of your data then there is also Snapraid tool that can be interesting.

This is exactly where I came to. I've set up SnapRaid and mergerfs. For home usage it's almost perfect.

It's hard to give a single recommendation that applies to everyone needs unfortunately.

You right, especially when there are not so much options, since ZFS and Btrfs are not ready yet. But I hope since we now have good ARM based hardware storage solution, like Helios64, this will change soon.

[filesystem for raid5]

I've got my helios64 recently, and I wonder what type of FS to choose for main storage. I have five 4TB disk drives. I've installed OMV, made raid5 and format it with XFS. I use XFS because I work with this FS on Centos on my x86 servers, I don't use ext4 because I don't like when sometimes it starts to check filesystem during boot process. My setup is working perfect for a couple of weeks. I don't have any reboots or freezes or any issues that I've read on this forum. Now I think about migrating from XFS to BTRFS or ZFS. The main reason is to have file check-summing and scrub. Does anybody have btrfs with raid5 or ZFS with raidz1 on Helios64? Do you have any problems with it? Also, as I know, Synology uses btrfs on top of mdraid. Is it ok to use it like this on Helios64? I've read debates about this filesystems on this forum, but I would like to know if anybody is really using it on Helios64.

 

This is my version: Linux helios64 5.9.11-rockchip64 #20.11.1 SMP PREEMPT Fri Nov 27 21:59:08 CET 2020 aarch64 GNU/Linux
