Extend existing zpool volume size without any data loss is possible ?

[GHANESAN]

Dear Team,

In customer using Freenas file server, they are using Zpool volume size is 800GB. They are asking for adding 2TB harddisk in existing zpool volumes. It is possible to add 2TB harddisk and increase the size of zpool volume with out existing data loss. Because all user information stored on freenas server. Kindly provide your suggestion for increase storage space on zpool volume without data loss.

Freenas server running on vmware virtual machines. we will plan to add harddisk on server and create raid. After add datastore on VMware Esxi and then will add virtual hard disks on freenas file server. And extend the existing zpool volumes size. please provide the support for without loss data.

Thanks in advance

You can add additional vdev's to a pool, however do not add single drives because if the drive fails, you lose the pool. Make sure you're adding them as mirrors or RAIDZ2.

Don't create raids and add them to a datastore and add them to freenas.
Freenas needs direct access to the hdds
