FreeNAS- DEGRADED

[silva_lcs]

Guys, I need some help. I'm in a frenzy FreeNAS-11.1-U4 compilation Intel (R) Core (TM) i5-4440 CPU @ 3.10GHz Platform Memory 24409MB System hours Mon, 24 Jun 2019 11:27:11 -0300 Time Spent 11:27 AM up 30 days, 23:01, 0 users Average Load 1.20, 0.73, 0.60 We have 10 4Tb disc. I'm getting the message "DEGRADED." How can I proceed and what are my risks?

zpool status output would be a good start

Hi,

So what is it that you do not understand ?

The pool is critical because it is loaded at 95%. Should you hit the 100% you may end up unable to access the pool at all, so you may loose all of your data. Make room in that pool ASAP either by deleting snapshots, data or both.

As for the fact that a hard drive has been removed by an administrator, again, what is it that you do not understand here ? Replace that drive and re-silver the pool...

Thanks for the help, how do I free up space?

how do I lock storage, not to reach 100%?

You need to read more before asking questions...

 

[silva_lcs]

delete some files via smb but no NAAS did not free space ?

Hey Silva,

This is very possible if you have snapshots. Consider that when snapshot is taken, you have file A and file B but no file C. After the snapshot, you modify file A and create file C. At the end, you will use the space of file A version 1, file B, file C and file A version 2. Should you delete file B, you will not save anything because file B as is existed for both the main instance of the dataset plus the snapshot. It is now removed from the main dataset, but is still required for the snapshot, so it is kept online and will continue to use the corresponding space.

I put a new HD and it remains degraded

Please read through the doc section 9.5.1 under "Replacing a Failed Disk"

https://www.ixsystems.com/documentation/freenas/11.2-U5/storage.html#replacing-a-failed-disk

For your free space issues, check in your FreeNAS UI under Storage->Snapshots and see if there are any snapshots present there. If you have snapshots, deleting a file will not free up space until it is removed from all snapshots.

Please also post the output of the command zpool status Jussi_P1_R6 within the CODE tags (Insert->Code)

Finally, please provide some more information about the rest of your system, especially the motherboard and the HBA being used to connect the drives.

Thanks for the help, but the step quoted from the document is not according to the version of my Freenas, I still can not get the status "degraded" from my freenas, the disks are all "ok" but the status persists

In the upper-right corner, you can change the document version to reflect a prior version; although if you're too far behind, an upgrade might not be a bad suggestion.

There are more steps than just physically replacing the disk - you must inform ZFS to update the pool itself, and then once the resilver has completed, a scrub might be a good idea to check the data integrity of the pool as well. Instructions for this are in the linked documents.
