过去两天，我一直在尝试为我的磁盘转储创建 2TB btrfs。我强制压缩 zstd。我将其安装如下：defaults,nofail,compress-force=zstd
这是我第二次尝试，但两次我都尝试写入 1.5TB 的备份映像，但两次 btrfs 都失败了。
两次复制大文件时，文件系统都会变为只读。在 syslog 中，我有以下内容：
Oct 25 18:59:20 omv kernel: [ 3452.595259] BTRFS error (device dm-2): bad tree block start, want 90110312448 have 9500881985411515836

卸载并重新启动后，我无法再次安装它，我得到：
mount: wrong fs type, bad option, bad superblock on /dev/mapper/vdd-crypt,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
运行 btrfsck 得到以下结果：
couldn't open because of unsupported option features (10).Couldn't open file system
Running zero-log gives me:couldn't open because of unsupported option features (10).
ERROR: could not open ctree
Dmesg 中填充了以下内容：
[ 56.092845] BTRFS error (device dm-2): parent transid verify failed on 21037056 wanted 209 found 207
[ 56.104033] BTRFS error (device dm-2): parent transid verify failed on 21037056 wanted 209 found 207
[ 56.104203] BTRFS error (device dm-2): failed to read chunk root
[ 56.124933] BTRFS error (device dm-2): open_ctree failed
这是正常的吗？如何修复？通过在不同的 SATA 控制器上使用不同的硬盘和不同的 SATA 端口，我能够达到几乎相同的状态。
此外，在这两种情况下，整个文件系统都只有一个目录和四个大文件。
btrfs-progs 更新到新版本后，我得到：
