ZFS RaidZ1 Questions

[MrBrac]

So currently I have 13 disks all 8 tb 2 of them are now empty with 3rd on the way to be empty.

 

I want to migrate my XFS to ZFS.

 

so can I make a ZFS RaidZ1 pool of 3 x 8 TB and move data then add more 8tb to that raidz1 ?

 

Can I do that in a pool then move the pool to array when clear?

zfs does not currently allow expanding raidz vdevs, though it should in the future, for now you can only expand by adding another vdev, so if you have 3 x 8TB you can later add another 3 disks, same or different capacity.

So I have to wipe my entire array then if I want to do ZFS.

If you want a zfs pool yes, if you want array disks formatted zfs you can change one by one.

Ok wait can I put all my disks as unassigned and move all data to zfs array one by one?

Can I swap my array with a pool ? can I have a pool of xfs?

[JorgeB]

You can use the same process to convert filesystem as used for example for xfs:

So it would be ZFS array with no RAIDZ right but with FS features of ZFS ? So XFS < ZFS

 

Can I pool my XFS disks so I have small ZFS array and XFS pool?

You can't have everything, zfs on the array won't have for example better performance and self healing, see below for more info:

you cannot expand a raidz pool with a single disk (at least not for now), you can add another vdev of the same width, say for example you have a 4 disk raidz1 pool, you can add another 4 disks in raidz1 to expand it

 

Its not soon for the pool to add same vdev thing huh?

 

I can have ZFS compression on the array right and other features except performance and self healing..

 

What about my XFS disks can I make a 2nd pool and them like an array to move data?

 

Last question if you where in my spot would you move to ZFS or stay XFS.

 

Is ZFS so great that I should move?

 

If I go ZFS array in future can I make a a ZFS RAID Z with same data?

If I put this one disk in array as zfs would it work with unraid without a format?

 

I did zpool create -m /mnt/zfs1 zfs1 sdd

 

forget everything I been saying I am all good now.

 

Simple question off topic.

 

I got a EVGA 650 watt PSU I think I need upgrade or swap to better one

 

I have 13 HDDS + 3 SSDS and a 1080 TI AMD Ryzen. Is that enough power?
