From 91ead15283200feb9db8054a26d322fbfdc3fa59 Mon Sep 17 00:00:00 2001 From: Giuseppe Scrivano Date: Thu, 28 Apr 2022 11:39:12 +0200 Subject: volume: add new option -o o=noquota add a new option to completely disable xfs quota usage for a volume. xfs quota set on a volume, even just for tracking disk usage, can cause weird errors if the volume is later re-used by a container with a different quota projid. More specifically, link(2) and rename(2) might fail with EXDEV if the source file has a projid that is different from the parent directory. To prevent such kind of issues, the volume should be created beforehand with `podman volume create -o o=noquota $ID` Closes: https://github.com/containers/podman/issues/14049 Signed-off-by: Giuseppe Scrivano --- libpod/volume_internal.go | 3 +++ 1 file changed, 3 insertions(+) (limited to 'libpod/volume_internal.go') diff --git a/libpod/volume_internal.go b/libpod/volume_internal.go index 9850c2ea1..e0ebb729d 100644 --- a/libpod/volume_internal.go +++ b/libpod/volume_internal.go @@ -52,6 +52,9 @@ func (v *Volume) needsMount() bool { if _, ok := v.config.Options["SIZE"]; ok { index++ } + if _, ok := v.config.Options["NOQUOTA"]; ok { + index++ + } // when uid or gid is set there is also the "o" option // set so we have to ignore this one as well if index > 0 { -- cgit v1.2.3-54-g00ecf
