Utvide ZFS pool med ny RAIDZ VDEV

Rimelig rett frem, det vil riktignok ikke være noen rebalansering av data, så dette må en ta seg av selv. Fordelen er jo at kommandoen er ferdig på sekunder og plassen kan utnyttes umiddelbart.

Først kjørte jeg kommandoen med oppsjonen “-n” for å være sikker på at den var korrekt.

# zpool add -n tank raidz ata-HGST_HDN724040ALE640_PK1381PCJSZ50S-part4 ata-HGST_HDN724040ALE640_PK1381PCJT6EWS-part4 ata-HGST_HDN724040ALE640_PK1381PCK3N9DS-part4 ata-HGST_HDN724040ALE640_PK1381PCKZ840S-part4
would update 'tank' to the following configuration:
tank
raidz1
ata-HGST_HDS724040ALE640_PK1334PBGX5SJS-part4
ata-HGST_HDS724040ALE640_PK1334PBGY417S-part4

Ser riktig ut, så da kjører vi kommandoen.
