Hi, everyone
I found btrfs will hangup when we run the sync command on my
x86_64 box.
The reproduce steps is following:
# mkfs.btrfs -s 8192 -l 8192 -n 8192 /dev/sda1
# mount /dev/sda1 /mnt
# echo 1234567> /mnt/aaa
# sync
(btrfs hangs up)
It seems that the btrfs doesn't support the sectorsize which is
greater than the page size just like ext2/3/4, though we can use
mkfs.btrfs to make a filesystem with a big sectorsize. Am I right?
If yes, we must do more check in the mkfs.btrfs.
yes, btrfs doesn't support the sectorsize> PAGE_size.
So we must do more check in the mkfs.btrfs to avoid misuse, and I'll
add some check of the sectorsize into the mkfs.btrfs.
BTW, I sent some patches to the btrfs community recently, but I haven't received
any reply. Could you review them for me? though I have tested them and
everything
works well.
[PATCH 1/2] btrfs: restructure try_release_extent_buffer()
[PATCH 2/2] btrfs: fix oops when leafsize is greator than nodesize
[PATCH] btrfs-progs: fix wrong extent buffer size when reading tree block
Thanks
