Hi all,
Hi Goffredo,
This is the third attempt of my patches related to show how the data
are stored in a btrfs filesystem. I rebased all the patches on the
latest mason git
it as a question in case you do not know
for sure.
According to my irregular data points I also see no significant increase in
wear out after I switched BTRFS to /home although it is a bit premature to
say for sure - I will continue to have a look at it:
martin@merkaba:~/Computer/Merkaba/Intel SSD
/ctrl/root/snap3' and umount
/mnt/ctrl again.
I use it that way, but I use
btrfs subvolume set-default NUMBER /mount/path
in order to not have to put the subvolid option into fstab.

happen on file data it should be possible to delete the offending file,
but then AFAIK BTRFS also reports on which file they happen.

Anyway, to find the real error message its necessary to try to delete

Hi Duncan,
Beyond this corrupted file, is my disk dead?
Can I repair the file system or re-create a new one on the same disk?
A direct answer is beyond my knowledge level, certainly without SMART
status information, etc.
I attach the result of `smartctl -x` below.

Hi Duncan,
The kernel log (dmesg, also logged to syslog/journald on most systems)
from during the scrub should capture more information on those errors.
Thanks. The dmesg log indeed contains the file path (see below).
The error is in /home/martin/X. It is related to a low-level error

It should show renamed or moved files. But yeah, if it does, at least not
in a way that shows that a rename or move operation took place.
c) it seems to work only for one subvolume?
Its per subvolume, I think. Thats why it is under btrfs subvolume
