Hello,
if I create a raid10 it looks like that:
mkfs.btrfs -m raid10 -d raid10 /dev/sdb /dev/sdc /dev/sdd /dev/sde
but if I've different jbods and I want that every mirror of a raid10 is on a
different jbod how can I archive that? in zfs it looks like that:
zpool create -o ashift=12 nc_storage m
:(
that means when one jbod fail its there is no guarantee that it works fine?
like in zfs? well that sucks
Didn't anyone think to program it that way?

Hello,
does exist an roadmap or something like "what do first/next"?
I saw the project ideas[1] and there are a lot of intersting things in it (like
read/write caches, per subvolumes mount options, block devices, etc), but there
is no plan or an order of ideas. Did btrfs has something like that?
a raid01 it does not fit in our use case + I can't
configure which disk is in which mirror..

Hello,
if I run 'bonnie++ -c4' the system is unusable and hangs, I got also some
CallTraces in my syslog. Is that a normal behavior?
My system is:
uname -a
Linux tani 4.19.0-0.bpo.1-amd64 #1 SMP Debian 4.19.12-1~bpo9+1 (2018-12-30)
x86_64 GNU/Linux
btrfs fi sh
Label: none uuid: 24be286b-ece
so a simple
btrfs fi resize -4k /
do that trick?

yep you're right, but the most sysadmin expect some 'policies'.
If I use RAID1 I expect that if one drive failed, I can still boot _without_
boot issues, just some warnings etc, because I use raid1 to have si
sorry for disturb this discussion,
are there any plans/dates to fix the raid5/6 issue? Is somebody working on this
issue? Cause this is for me one of the most important things for a fileserver,
with a raid1 config I loose to much diskspace.
best regards

Dear Maintainer,
the command btrfs fi show takes too much time:

any recommendations for strace options?

Hello,
I've played a little bit with raid1:
my steps was:
1. create a raid1 with btrfs (add device; balance start -mconvert=raid1
-dconvert=raid1 /)
2. after finishing, i shutdown the server and remove a device and start it
again,
3. it works (i used degraded options in fstab)
4. I shutdown the
