zpool status is not good

[thiagocpv]

Hello Guys!

I am not expert but I am using FreeNas a few years and now I am getting an alert error when log on at the web interface and when running zpool status -v as well.
The error is about the disk spool (attached the print screen and see below the same info).
I don't have sure if I can repair it without loss data. Could everyone guide me on that?

pool: Storage
state: DEGRADED
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the entire pool from backup.

see: http://illumos.org/msg/ZFS-8000-8A

scan: scrub repaired 0 in 9h7m with 6 errors on Sun Sep 10 01:19:41 2017

config:

NAME STATE READ WRITE CKSUM
Storage DEGRADED 0 0 422K
gptid/1c8bcec0-6b46-11e4-a867-001e67125910 DEGRADED 0 0 845K too many errors

errors: Permanent errors have been detected in the following files:

/mnt/Storage/Storage.file
pool: freenas-boot
state: ONLINE
scan: scrub repaired 18K in 0h9m with 0 errors on Sun Oct 1 03:54:50 2017

config:

da0p2 ONLINE 0 0 0
errors: No known data errors

Thank you very much!

Run a memory test.

No, because you don't have any redundancy. You have to restore from backup.

I did memory stress test and it was OK.
About the backup, I don't have a full backup. This raw file has 5TB and I have 20 VM's running on that.
Is there other way?

Thanks Guys.

 

[Ericloewe]

You have 20 VMs running from a single disk?

Is there other way?

Sure. Time travel, magic, random guessing until the checksums match, stalling until you die so that it becomes someone else's problem... I wouldn't call any of them remotely usable.

I mean, what the hell. What other magical solution do you expect? How about taking some responsibility instead of setting up an unreliable server with no backups and then asking if there's a solution?

Is there other way?

No. You set up a pool with no redundancy*, and never bothered to make a backup, so now there's no way to repair the damaged data. I'm with @Ericloewe--what did you expect? How did you expect to be able to magically repair data from a failing single disk?

* Unless you used some hardware RAID solution that's hidden to FreeNAS, which I think would be even worse than what it looks like you did.

Hold on guys, I have 4 disks in RAID 5. I mean, the customer has it! This environment is not mine. One disk failed and after replace the disk appears a message about the zpool and etc. All the environment is working but with this alert about the performance, etc.

The customer has limited money to invest and to my security I have an agreement about backup and others things. So first try to understand with more details the situation. Like I said I am not expert to try to recovery this one and I am here asking you guys.

Next time, please save your time avoid to respond stupidly the questions at this forum.

Thank you for spent time with this.

...and even more limited knowledge about how things should be done with FreeNAS, I see. Hardware RAID with FreeNAS is a really bad idea, as you're just now finding out.

Next time, please save your time avoid to respond stupidly the questions at this forum.

Next time, please save your time (and ours, really--your post with incomplete information is wasting your time as well as ours) to avoid posting stupidly. You know those forum rules you said you read and agreed to when you joined, just a couple of days ago? You really should follow them. Especially the part where it says to post the details of your configuration when you're asking for help.

I don't think it will help, but a zfs list and zpool list would be good to see whether all the details match up here.

Was the memory test done today?
