Resize command syntax wrong?
Currently the resize command is under filesystem, and takes a path to the mounted filesystem. This seems wrong to me. Shouldn''t it be under device, and take a path to a device to resize? Otherwise, how can a resize operation when you have multiple devices make any sense? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

make snapshot main volume, delete all others?
Fedora provides yum-fs-snapshot. If installed, on each package installation or update a snapshot of all btrfs filesystems is taken, so it is possible to revert the installation/update. Suppose an update failed and I want to get back: with # btrfs subvolume set-default yum-snapshot-whatever / I define which snapshot to use at the next boot. After rebooting I decide I really want to stay with

[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).

Resizing a btrfs managed partition
Hi, Let me know if this is the wrong place to ask... I''m using Fedora 12 x86_64, mostly with the newer 21.6.32 kernel, and have a single btrfs filesystem within a 120Gb partition. I''d like to extend the space btrfs can use. One option is presumably add a new device to btrfs, but I was hoping to simple resize the existing partition to say 160Gb. With ext4 I might do

[Btrfs-Progs] Update for lzo support
- Add incompat flag, otherwise btrfs-progs will report error when operating on btrfs filesystems mounted with lzo option. - Allow to turn on lzo compression for defrag operation: # btrfs filesystem defragment -c[zlib, lzo] <file> Note: "-c zlib" will fail, because that''s how getopt() works for optional arguments.

[PATCH 0/3] Btrfs: add IO error device stats
The goal is to detect when drives start to get an increased error rate, when drives should be replaced soon. Therefore statistic counters are added that count IO errors (read, write and flush). Additionally, the software detected errors like checksum errors and corrupted blocks are counted. An ioctl interface is added to get the device statistic counters. A second ioctl is added to atomically get
