Resize to nums without sign prefix makes false output: btrfs fi resize 1:150g /srv/extra Resize device id 1 (/dev/sdb1) from 298.09GiB to 0.00B
The resize operation would take effect though. check_resize_args() does not handle the mod 0 case and new_size is 0. Simply assigning @diff to @new_size to fix this. Issue: #307 Reported-by: Chris Murphy <li...@colorremedies.com> Signed-off-by: Su Yue <l...@damenly.su> --- Changelog: v3: Just assign @diff to @new_size. (Boris Burkov) v2: Calculate u64 diff using max() and min(). Calculate mod by comparing new and old size. --- cmds/filesystem.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/cmds/filesystem.c b/cmds/filesystem.c index 9e3cce687d6e..b4c09768235c 100644 --- a/cmds/filesystem.c +++ b/cmds/filesystem.c @@ -1158,7 +1158,10 @@ static int check_resize_args(const char *amount, const char *path) { } old_size = di_args[dev_idx].total_bytes; - if (mod < 0) { + /* For target sizes without '+'/'-' sign prefix(e.g. 1:150g) */ + if (mod == 0) { + new_size = diff; + } else if (mod < 0) { if (diff > old_size) { error("current size is %s which is smaller than %s", pretty_size_mode(old_size, UNITS_DEFAULT), -- 2.30.1
