similar to: [PATCH] btrfs: accept zero for balance usage filter

Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.

A bunch of fixes (memory leaks, NULL pointer dereferences and devices hanging in busy state) to sanitize error handling during mount sequence. This is on top of for-linus + slyfox''s double-free fix. Thanks, Ilya Ilya Dryomov (5): Btrfs: fix memory leak in btrfs_parse_early_options() Btrfs: fix subvol_name leak on error in btrfs_mount() Btrfs: avoid null dereference and leaks

Hello, This is the userspace part of restriper, rebased onto the new progs infrastructure. Restriper commands are located under ''balance'' prefix, which is now the top level command group. However to not confuse existing users ''balance'' prefix is also available under ''filesystem'': btrfs [filesystem] balance start btrfs [filesystem] balance

Josef''s fs_mark test fs_mark -d /mnt/btrfs-test -D 512 -t 16 -n 4096 -F -S0 on a 2GB single metadata fs leaves about 400Mb of metadata almost unused. This patch reduces metadata chunk allocations by considering the proper metadata chunk size of 200MB in should_alloc_chunk(), not the default 256MB which is set in __btrfs_alloc_chunk().

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially.

Setting subvolume/snapshot readonly has been missing for a long time.

Back story: I started my pool with a 200gb partition at the end of my drive (sdc5) , until I was able to clear out the data at the beginning of my drive.

Currently mkfs in response to mkfs.btrfs -d raid10 dev1 dev2 instead of telling "you can''t do that" creates a SINGLE on two devices, and only rebalance can transform it to raid0. Generally, it never warns users about decisions it makes and it''s not at all obvious which profile it picks when. Fix this by checking the number of effective devices and reporting back

Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata.

NOTE: in order to apply this patch you should: git mv btrfsck.c cmd-fsck.c This patch moves btrfsck in to "btrfs fsck". It also adds support for symlinks to the btrfs binary to retain compablity, =) I think something should be done to the help description but i''m not sure what... Anyway, feedback is welcome. -- To unsubscribe from this list: send the line "unsubscribe

Hi. I'm attempting to fit a logistic/binomial model so I can determine the influence of landscape on the probability that a box gets used by a bird. I've looked at a few sources (MASS text, Dalgaard, Fox and google) and the examples are almost always based on tabular predictor variables. My data, however are not. I'm not sure if that is the source of the problems or not because the

Currently there are error paths in btrfs_rm_device() where EINVAL is returned telling the user they passed an invalid argument even though they passed a valid device. Change to return EPERM instead as the operation is not permitted.

Document those places in the btrfs code which are BUGing on non-fatal error conditions that should be handled by proper error paths. This makes it easier to distinguish between what needs fixing versus which BUG_ON''s we might want to keep (to trap code bugs, unexpected inconsistencies, etc). Do this with a trivial macro, ''btrfs_fixable_bug_on'' which just defines to

Comments? Feature request: Add the ability for the "T" and "t" suffixes in a Dial command to call an extension directly (if specified) instead of going only to the hardcoded "transfer" command. Feature request: Flash events, when presented inside of an existing call, will call a pre-specified extension just like the "T" and "t" request

I''m using Xen 3.4 on Debian Lenny, and a web interface (still in dev), to have a eye on all the stuff. I saw the Xen Cloud project, but I have some questions about it. Can I summarize Xen Cloud like this : "latest" Xen Hypervisor with "improved" API (OCaml replacing python and more stuff) which enhance informations about all Xen hypervisors in same time, to provide a

Doing this would reliably fail with -EBUSY for me: # mount /dev/sdb2 /mnt/scratch; umount /mnt/scratch; mkfs.btrfs -f /dev/sdb2 ... unable to open /dev/sdb2: Device or resource busy because mkfs.btrfs tries to open the device O_EXCL, and somebody still has it. Using systemtap to track bdev gets & puts shows a kworker thread doing a blkdev put after mkfs attempts a get; this is left over
