search for: space_cache

So when I added the clear_cache option I screwed up and took the break out of the space_cache case statement, so whenever you mount with space_cache you also get clear_cache, which does you no good if you say set space_cache in fstab so it always gets set. This patch adds the break back in properly. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> --- fs/btrfs/super.c | 1...

Rename no_space_cache option to nospace_cache to be more consistent with the rest, where the simple prefix ''no'' is used to negate an option. The option has been introduced during the -rc1 cycle and there are has not been widely used, so it''s safe. Signed-off-by: David Sterba <dsterba@suse...

Hi, Recently, I made a btrfs to use. And I met slowness problem. Trying to diag it. I found this: 1. dd if=/dev/zero of=test count=1024 bs=1MB This is fast, at about 25MB/s, and reasonable iowait. 2. dd if=/dev/zero of=test count=1 bs=1GB This is pretty slow, at about 1.5MB/s, and 90%+ iowait, constantly. May I know why it works like this? Thanks. -- To unsubscribe from this list: send the

Hello, I wanted to make sure that my boot slowdown was related to space_cache so I rebooted the PC several times and it did become slower again. What is more, it doesn''t seem like I even need to generate any actual IO traffic to trigger this. I thought I might give clear_cache a shot again and to test the boot speed with nospace_cache as well. After first booting w...

When adding orphans to an inode''s root, we start a transaction for that root that when ended in several places such as for example extent-tree.c:btrfs_remove_block_group(), inode.c:btrfs_unlink() and inode.c:btrfs_evict_node(), doesn''t result in a commit, that is, inode.c:btrfs_orphan_commit_root() doesn''t get called (via transaction.c:commit_fs_roots()).
