Subject: Re: spurious full btrfs corruption

Hey Qu.

Some update on the corruption issue on my Fujitsu notebook:


Finally got around running some memtest on it... and few seconds after
it started I already got this:
https://paste.pics/1ff8b13b94f31082bc7410acfb1c6693

So plenty of bad memory...

I'd say it's probably not so unlikely that *this* was the actual reason
for btrfs-metadata corruption.

It would perfectly fit to the symptom that I saw shortly before the fs
was completely destroyed:
The spurious csum errors on reads that went away when I read the file
again.



I'd guess you also found no further issue with the v1 space cache
and/or the tree log in the meantime?
So it's probably safe to turn them on again?



We(aka you + me testing fixes) can still look in the issue that newer
btrfsprogs no longer recover anything from the broken fs, while older
to.
I can keep the image around, so no reason to hurry from your side.



Cheers,
Chris.
