Hello guys, can't find any instruction on adding a new drive to raidZ.

maybe something like this?

Thread 'Adding new disks to Raidz'

So I'm trying to do something I thought was simple. I have a SSD pool with 4 identical 1,6TB Dell enterprise drives, and I want to add two more. Here's the output of the pool status for that pool:

pool: fastsas5
state: ONLINE
config:

NAME STATE READ WRITE CKSUM
fastsas5 ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
scsi-35001e82002774394 ONLINE 0 0 0

Hello, I don't think that this is what i need. The thread was in 2022 and adding new drive to existing pool was introduced just recently in proxmox 9

I believe this is not implemented in the Gui (yet?).

On commandline it works as intended. man zpool-attach tells you the syntax.

This is a manipulation on the lowest level and failures may be fatal. Personally I do set a global checkpoint to have a way back to the previous state. See man zpool-checkpoint.

General disclaimer: be careful and have restorable backups available. I do test things like this before I run it on a productive system. In my Homelab(!) I have a virtual cluster for "dangerous" experiments.

Hello UdoB, Here is said that:
Here are some of the highlights of the Proxmox VE 9.0 beta version
  • Ceph Squid 19.2 is the new default and comes with continued support
  • SDN Fabrics for complex routed networks, enabling advanced use cases like two-layer spine-leaf architectures or a full-mesh Ceph cluster.
  • Snapshots for thick-provisioned LVM shared storage, e.g., for setups connected over iSCSI or Fibre Channel to a SAN.
  • ZFS 2.3 with RAID-Z expansion. Doesn't that mean that you can't add another HDD to raidz1 in pre-9-version?
  • Countless GUI and API improvements.
  • and much more...
