[SOLVED] Server: changed reserved uid/git, change without reboot

Hello,

I have a server which I cannot reboot at the moment. I changed the gid/uid which is allowed to use the reserved blocks on an ext4 partition.
Remounting the partition does not change the uid/gid the kernel uses. Is there an option to tell the kernel that I changed the values without umounting the partition.

Remounting the partition does not change the uid/gid the kernel uses.

What does that mean?
Are updated resgid/resuid reflected in the output of "mount"?
How exactly do you remount the partition and are there any errors (eg. because it's in use…)?

Thank you so much, your response helped me to fix my issue. (I found the options in the mount output)
I only remounted the partition with `mount -o remount /`. This command does not reread the info when updated with tune2fs. I specified the mount options resuid and resgid and now everything is working without reboot.
