FreeNAS Degraded Pool

[grimreeper132]

So summary is, I messed up a recently and accidently pulled out one of my drives, now I am getting a degraded state warning. The drives seams to be fine far as I know so how do add it to the pool to fix it again and get rid of the warning etc.

cli or  gui?

 

Add the drive back in, the online the drive, then scrub.

you gotta online the degraded disk before the scrub, otherwise it won't rebuild anything.

From my own experience at least with the old WebUI versions if FreeNAS I was simulating drive failure to my college class by disconnecting a drive which resulted in a degraded state.

 

I was able to make the pool come back up as healthy by simply reconnecting the disk and restarting the server.

 

Something you may be able to try next time around. I see Electronics Wizardry has you covered.

Makes me wonder if the pool was performing an operation that may have corrupted something. Failed a check of some sort so the pool rejects the drive at startup. Re-silvering is always an option too but takes time depending on how much data you have. A scrub should correct errors if the majority of the correct data is still there.

 

I have to ask as I have not played with the newer WebUI versions of FreeNAS does it give you an option to keep using the Legacy WebUI?

I had a failing HBA give me heart attacks thinking it was going to take out my pool, and ZFS didn't give two craps about it.  It just kept on trucking.

 

I replaced the failing HBA, online the disk, and then ran a scrub to check everything out and all was well

 

On the main Dashboard, from the left browser tree click "Storage" then "Pools".  From there, click the "Gear" icon next to your degraded pool, and choose Status front pop-up menu.

 

From there, you have 3 Ellipses next to each disk, clicking that eclipse will give you EDIT, ONLINE/OFFLINE, and REPLACE options.

 

Online the disk, then scrub the pool to make sure its all hunky dory.

FreeNAS should automatically Resilver the disk as soon as the missing disk is brought back online.

 

The scrub is just to check if all is well with the entire pool and correct any errors that were missed.

It did this for me during my own experimentation but OP did not have the same experience.
