RN214 btrfs corruption forced readonly

[aeldaly]

I'm getting BTRFS corruption...

So it started with turning on teaming for the NIC cards in network settings. The device locked up and I had to force restart it. When it did, it started a rebalance that took about 20 hours. When it was done, I noticed that the system was much slower than before.

So I searched around here in this forum and there was a thread about doing a full rebalance to fix the issue. I'm sorry I do not remember the command, but it was to echo to a file and reboot.

It ran for 2 days or so. When I came back from work today it was done. So I mounted the drives on my laptop and as I started using it I noticed that the file system was read only. dmesg showed:

BTRFS critical (device md126): unable to find logical 407721705472 len 4096

and:

[<c001524c>] (unwind_backtrace) from [<c001173c>] (show_stack+0x10/0x18)

I decided to reboot again to see if that may fix it. It rebooted successfully and dmesg showed not errors. I could right to the filesystem. For a bit. And then it's hapenned again. I've shutdown the system, and would appreciate all support to hopefully fix this issue.

Thanks.

I'd start by booting it up read-only (if it's not read-only already)  and making a backup of the files.

Yes, try rebooting into read only mode. You might be able to access the data then and take a backup if you don't have one already.

Do you have a recent log-set? I can take a quick look at it if you like. You can make a Google link or something similar and PM me that.
