i built my first NAS earlier this year. it’s running TrueNAS scale, and currently has 2 12 tb drives in a mirror for storage. when i built it, i knew i would need more storage eventually, so my plan was to use ZFS expansion to add more storage once it was roughly 80% full. it hasn’t hit that point …

so, i did end up picking up that 20 tb external drive that was on sale at best buy. i already had a smaller external drive with my really life critical stuff backed up to it, but being able to have an offline backup of everything else was appealing. i’m backing everything up to it now, which will t…

okay, thank you both.i don’t have enough storage space elsewhere to back up the current mirror and build a new proper 4 drive raidz2 pool. before you judge my data backup practices, this nas is just for personal use, and all of the truly life critical stuff on it is backed up elsewhere. i’m leaning…

I would stick with just the mirror pairs. I don’t know if you can do the 3 drive Raid-Z2 in the GUI. It might require command line work and if your single data disk goes down in all of this, there goes all your data. If you could have your current data backed up in two separate places and then co…

[image] deafhobbit: however, i just realized there is a way i could get to raid z2 without buying more storage or building a “degraded pool.” copy all my current data to one of the new drives create a new 3 drive Raid Z2 pool from the other new drive + both existing drives copy the data backed…

Testing in a Virtualbox VM to see if I can create degraded Z2 with three drives using GUI I tried to add a Z2 with 3 disks, using manual disk selection. no go. I think it has to be done by CLI? [image]

huh, seems weird that z2 requires 4 drives. a pool with 3 drives all mirroring each other seems like it could make sense for some situations. i’ve been daily driving linux on desktop for about a year now. i’ve done plenty of basic command line stuff there, and some in truenas as well. is there a gu…

thanks. there wasn’t anything like this in the truenas docs, and i didn’t think to google around for zfs stuff elsewhere. this is definitely on the edges of my command line proficiency. i’ll need to think about it. in the meantime, if i were to do this, what would be the proper way to do step 1? a…

If you’re considering manual CLI, my opinion is you’ll have to commit fully to CLI. I’m not sure what you mean by ‘proper way to do step 1’ or hooking up drives, so I’ll just vomit the steps at you & hope they answer your question. Keep in mind, if you’re following the guide for your purposes, you…

yeah, i am thinking about getting a 5th drive for the NAS, or even just 6 tb of other storage i could back up the NAS’s current contents to temporarily so i could create a 4 drive raid z2 pool. raid z2 definitely seems like the best option for me long term. switching to it is tricky though, and it …

Can you use the Best Buy deal? Some people get these for the drive inside, shuck them and use them in a NAS. It would be useful for your temp use and then …
