btrfs and lz4

[f1vefour]

I was simply following the advice of the BTRFS wiki. I did provide a link that warned of the potential danger on the page.

Thanks for coming behind me and warning against this, I'm certainly no filesystem guru.

Apparently you know more than they do, the wiki simply says:

Quote:if and only if the kernel oops in your logs has something like this in the middle of it, or you get "open ctree failed" on a newer kernel:

? replay_one_dir_item+0xb5/0xb5 [btrfs] ? walk_log_tree+0x9c/0x19d [btrfs] ? btrfs_read_fs_root_no_radix+0x169/0x1a1 [btrfs] ? btrfs_recover_log_trees+0x195/0x29c [btrfs] ? replay_one_dir_item+0xb5/0xb5 [btrfs] ? btree_read_extent_buffer_pages+0x76/0xbc [btrfs] ? open_ctree+0xff6/0x132c [btrfs]

Newer kernels output this instead:

BTRFS: failed to read log tree BTRFS: open_ctree failed

To be fair it says nothing about it being compression related.
