Bei einem meiner Proxmox VE Hosts habe ich aus einem ZFS RAID0 (stripe, also mehr Speicher) ein ZFS RAID1 (mirror, mehr Sicherheit) gemacht. Hier die notwendigien Schritte dazu:
1. Überblick verschaffen
Bash
root@brix22:~# zpool status
pool: rpool
state: ONLINE
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
nvme-eui.00000000000000008ce38e03006ad3b3-part3 ONLINE 0 0 0
ata-SanDisk_SDSSDH3_1T02_2012AB448604-part3 ONLINE 0 0 0
errors: No known data errors2. Einen Datenträger (hier SanDisk SSD) aus dem rpool (RAID0, stripe) entfernen
Bash
root@brix22:~# zpool remove rpool ata-SanDisk_SDSSDH3_1T02_2012AB448604-part33. Diesen Datenträger wieder dem rpool als mirror für RAID1 hinzufügen
Bash
root@brix22:~# zpool attach rpool nvme-eui.00000000000000008ce38e03006ad3b3-part3 ata-SanDisk_SDSSDH3_1T02_2012AB448604-part34. Fortschritt prüfen
Bash
root@brix22:~# zpool status
pool: rpool
state: ONLINE
status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
