Howdy,
So I run several gentoo systems and I upgraded two of them to kernel
3.17.0
One using BTRFS for root.
One using ext3 for root (via the ext4 driver)
_Both_ systems exhibited strange behavior (long pauses and then hangs
requiring hard-power) within several hours. Both then had random
filesystem damage.
On the BTRFS system much of my browser settings for firefox were
trashed, particularly the cookies and saved conifigurations for
add-ons (like which sites had scripts enabled/disabled in no-script)
etc.
On the ext3/4 system there were several corruptions including a
pipe/special file with a large non-zero size that required I do a
"fsck -fyD /dev/sda3" to repair. (one comment from fsck was that the
pipe/special file "looked like a directory" or some such)
So I can say that corruption is taking place, but I suspect it is
_not_ happening in the BTRFS specific code.
(ASIDE: both systems are older amd64 using built-in radeon display
hardware.)
I've also experienced Btrfs corruptions with 3.17.0 (Fedora 21 alpha).
It has happened two times, each one after a clean reinstall and a wipe
of the old fs. In less than a day, both installations got corrupted and
the filesystems went readonly. When listing the contents, I saw many
directories with question marks.
My system has 4 drives and 2 fs:
- 1 SSD in single
- 3 HDD in RAID1
I do readonly snapshots every hour of all the subvolumes, so I have
hundreds of snapshots.
Now I'm back in 3.16.4 without any problems. I'm trying to reproduce my
setup in a virtual machine. If the corruption happens again, I'll send
you more data on this problem.
