From e920bfb1e8a5917e7b0f360d1c51d200db3acbfd Mon Sep 17 00:00:00 2001 From: WANG Chao Date: Tue, 1 Apr 2014 15:20:49 +0800 Subject: [PATCH] fstab: do not mount and fsck from fstab if using systemd If using systemd in initramfs, we could run into a race condition when dracut and systemd both are trying to mount and run fsck for the same filesystem, and mount or fsck could be a failure. To fix such failure, we should use systemd to mount/fsck from /etc/fstab only. v2: check $DRACUT_SYSTEMD suggested by Alexander Tsoy Signed-off-by: WANG Chao --- modules.d/95fstab-sys/mount-sys.sh | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/modules.d/95fstab-sys/mount-sys.sh b/modules.d/95fstab-sys/mount-sys.sh index 12711a0..a237810 100755 --- a/modules.d/95fstab-sys/mount-sys.sh +++ b/modules.d/95fstab-sys/mount-sys.sh @@ -27,7 +27,11 @@ fstab_mount() { return 0 } -[ -f /etc/fstab ] && fstab_mount /etc/fstab +# systemd will mount and run fsck from /etc/fstab and we don't want to +# run into a race condition. +if [ -z "$DRACUT_SYSTEMD" ]; then + [ -f /etc/fstab ] && fstab_mount /etc/fstab +fi # prefer $NEWROOT/etc/fstab.sys over local /etc/fstab.sys if [ -f $NEWROOT/etc/fstab.sys ]; then
