From efe0286285a7432f738fafae840fa4eda51c2986 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 26 Feb 2015 00:40:43 +0100 Subject: machined: if /var/lib/machines is backed by a loop file, resize it on "machinectl set-limit" When the pool size limit is altered with "machinectl set-limit", then not only set the subvolume quota of the /var/lib/machine subvolume, but also resize the backing loop file and the btrfs file system on it dynamically. --- src/shared/btrfs-util.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/shared/btrfs-util.h') diff --git a/src/shared/btrfs-util.h b/src/shared/btrfs-util.h index 9a1eb3f383..e654a3fea1 100644 --- a/src/shared/btrfs-util.h +++ b/src/shared/btrfs-util.h @@ -60,6 +60,7 @@ int btrfs_subvol_get_quota_fd(int fd, BtrfsQuotaInfo *quota); int btrfs_reflink(int infd, int outfd); int btrfs_clone_range(int infd, uint64_t in_offset, int ofd, uint64_t out_offset, uint64_t sz); +int btrfs_get_block_device_fd(int fd, dev_t *dev); int btrfs_get_block_device(const char *path, dev_t *dev); int btrfs_defrag_fd(int fd); @@ -70,3 +71,6 @@ int btrfs_quota_enable(const char *path, bool b); int btrfs_quota_limit_fd(int fd, uint64_t referred_max); int btrfs_quota_limit(const char *path, uint64_t referred_max); + +int btrfs_resize_loopback_fd(int fd, uint64_t size); +int btrfs_resize_loopback(const char *path, uint64_t size); -- cgit v1.2.3-54-g00ecf
