Replaced a drive, now the volume shows degraded

[cyberjock]

Ok, so you have no redundancy at all. There's no mention of any kind of redundancy in zpool status. What you have amounts to a RAID0 of 3 disks. Not even sure how to help you with your problem as:

1. stripes are incredibly dangerous.
2. stripes are incredibly dangerous(I feel like I said this before)
3. So many people have lost stripes while trying to manage them with failing disks.

You should instead backup your data, destroy your pool, then recreate it with redundancy. You might be able to remove the disk from the CLI. But I'm not 100% sure.

I still have the data in another NAS and PC, time to start over again. Well, thanks.

Cyber,

your comment on stripes being incredibly dangerous has got me thinking if I shall be worried...

I have a total of 6 HDDs. HDDs 1, 2, 3 and 6 are set up by ZFS as mirrors. HDDs 4 and 5 are the stripe. I am currently running FN 9.2.1
If one of those stripe disks fails, how "worried" will I have to be? Am I correct to say that I am running under RAIDZ3 with these many disks?


Thanks for the help.

You can run 6 disks as stripes, mirrors, RAIDZ1, RAIDZ2, or RAIDZ3. What's important is how you actually did your setup. If you have any stripes, you are going to have a bad day when(not if) one of those starts having problems.

I did my setup following what the ZFS volume manager suggested under the GUI....Is there a better or worst way?

To summarize, there should not be any stripes at all? What good are they for then?

Thanks for the help!

 

[cyberjock]

That depends... the GUI could have chosen a number of combinations.....

stripes give amazing performance. For example, as a temporary workspace it is amazing.

arrrg...another roadblock. I can't afford to have data loss. I will have to redo my volumes and ensure no stripes are present.

Why not PM me a pastebin of your "zpool status" and I'll tell you if your system is striping anything.

This is how to set it up yes?!
