Thanks, this is helpful.
We are primarily scaling the number of snapshots. Unfortunately these
snapshots typically have very minor changes compared their parent, so
this sounds potentially problematic.
It sounds like I will need to do some testing of both snapshots and
quotas to determine
Hi all,
Starting today I have an interesting problem: I deleted some files as part (old
fcrontabs), which now persistently causes btrfs-send to fail. The error
message I get is:

-2: No such file or directory

Actually, it didn't resume. The btrfs delete missing was using 100%
of the I/O bandwidth but wasn't actually doing any disk reads of
writes. I tried to reboot, but the system wouldn't go down, so after
waiting 10 minutes, I power-cycled. Now I can't mount at all and
here's what dmesg says about

Ok, here's what's happening. A few years ago, I took my old WD green
drives and put them in a box as backups to a new array of Seagate
drives. When one of those seagate drives failed (just out of
warranty, of course), I replaced it with one of the WD's. That was
cooking along just fine until

I don't actually think that this is a BTRFS problem, but it's showing
symptoms within BTRFS, and I have no other clues, so maybe the BTRFS
experts can help me figure out what is actually going wrong.

They have many TBs of data.

Btrfs has been doing bio splitting from btrfs_map_bio(), by checking
device limits as well as calling -merge_bvec_fn() etc. That is not
necessary any more, because generic_make_request() is now able to
handle arbitrarily sized bios. So clean up

I have 2 identical servers with 2 x 2 Hitachi (HGST) SATA disks (and some
other disks) which are mirrored with drbd.
On top of this drbd setup I have created a btrfs RAID0 filesystem.
The problem now is, that btrfs shows the raw device instead of the drbd
