[PATCH] btrfs: flushoncommit mount option
Hi Chris- Here''s a simpler version of the patch that drops the unrelated sync_fs stuff. thanks- sage The ''flushoncommit'' mount option forces any data dirtied by a write in a prior transaction to commit as part of the current commit. This makes the committed state a fully consistent view of the file system from the application''s perspective (i.e., it

[PATCH] build: fix test for --nocompress option
The test for febootstrap-to-initramfs' --nocompress option was always failing for me on F11. Here's why: $ bash ~/w/co/libguestfs:210-comment-fix $ t=`febootstrap-to-initramfs 2>&1` [Exit 1] $ if ! echo $t|grep -sq -- --nocompress; then echo not found; fi not found Notice: without quotes, the [--nocompress] term expands to "k",

R: [PATCH 2/2] Btrfs-progs: add mount-option command
Hi Seto, please could you update also the man page too ? Why it was not provided a way to clear a *single* flag ? To me it seems a bit too long to clear all the flag (btrfs mount-option clear) and then set the right one. As user interface I suggest something like chmod: btrfs mount-option set +ssd,skip_balance -nodatacow /dev/sdX or btrfs mount-option set =ssd,skip_balance,nodatacow

[PATCH] Btrfs: allow subvol deletion by unprivileged user with -o user_subvol_rm_allowed
Add a mount option user_subvol_rm_allowed that allows users to delete a (potentially non-empty!) subvol when they would otherwise we allowed to do an rmdir(2). We duplicate the may_delete() checks from the core VFS code to implement identical security checks (minus the directory size check).

[RFC] Btrfs: Allow the compressed extent size limit to be modified v2
Provide for modification of the limit of compressed extent size utilizing mount-time configuration settings. The size of compressed extents was limited to 128K, which leads to fragmentation of the extents (although the extents themselves may still be located contiguously). This limit is put in place to ease the RAM required when spreading compression across several CPUs, and to make sure the

[PATCH] Btrfs: handle the space_cache option properly
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 + 1

zlib vs lzo uncompress speed, ssd vs nossd
I just setup a new SSD with my laptop root filesystem, and at the time I though, "eh, I''ll just use zlib compression during the first copy, and then switch to lzo afterwards to maintain write speed when I''m using the laptop after the copy and reboot". Now, I rebooted with the new ssd and zlib compressed rootfs, and it seemed to boot slower than it did before with the

[PATCH] btrfs: rename the option to nospace_cache
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.

kernel BUG at fs/btrfs/volumes.c:3707 still not fixed in 3.7.1 (btrfs-zero-log required) but shown as "RIP btrfs_num_copies"
Unfortunately my laptop deadlocks from time to time, and too often it triggers this bug in btrfs which is quite hard to recover from. The bigger problem is that all the user sees (if anything) is seemingly unrelated info, namely, "RIP: btrfs_num_copies+0x42/0x0b" or somesuch http://marc.merlins.org/tmp/btrfs_num_copies.jpg It''s only if you have serial console, or netconsole,

[PATCH v4] Btrfs: Check INCOMPAT flags on remount and add helper function
In support of the recently added capability to remount with lzo compression, provide a helper function to check the compression INCOMPAT flags when remounting with lzo compression, and set the flags if necessary. Also, implement the new helper function when defragmenting with explicit lzo compression and when setting the default subvolume. Signed-off-by: Mitch Harder

Suggestion for sticky-compression mount setting (default mount options)
As I''ve been using btrfs with an external USB drive, I wonder how to handle efficiently the compression setting. When I plug a drive in to ubuntu, it is automatically mounted. Its mounted without the compression option as its not in fstab. I don''t see it as desirable to install each usb drive in fstab on each computer that it may be used just so that compression is

wine/RosettaStone breakage from recent kernel commit
Hi, I've been running the foreign language training program The Rosetta Stone(TRS) on wine for months now, but a recent commit to the linux kernel has caused TRS to be unable to read the DVD drive, where the program's data files are kept. Strangely, winefile can still read the data DVD, but TRS cannot, and I'm stumped. Below is the guilty kernel commit (rather long, sorry). Can

BTRFS, getting darn slower everyday

Interesting problem with write data.
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
