TrueNAS Core - storage upgrade / harddrive replacement

TrueNAS General
1

Hello

I have a TrueNAS Core system (FreeBSD), the current harddrives are pretty old (but still zero problems/warnings) and I want to proactively replace them with new, nice harddrives.

How would you recommend going about replacing the harddrives?

Some additional information:

  • The system has plenty of capacity for harddrives, so I can fit/connect all, both old and new, harddrives at the same time.
  • The current pool (there is only one) is a bit old, for example TrueNAS shows “Legacy encryption”. So I am thinking that the new harddrives will be a new pool.
  • The new harddrives have more storage capacity than the current ones.
  • I use jails (note: not “plugins”), no other special features. Besides jails the system is a ordinary NFS NAS.

That depends on what the pool configuration is and how full it is and things like if you have any spare drive slots.

A new pool would imply snapshot replication. In theory you might be able to replicate the pool, remove the old pool, rename the new pool and everything just works, without reconfiguration. In theory

Look at migrating to TrueNAS Scale or finding a FreeBSD based NAS you can keep your Jails up to date. FreeBSD 13 series is EOL within about a month. You will have trouble with Jail maintenance after that.
