I might have been wrong with this, dmesg of my tests indicates that quotacheck does the rmount:
-->
[10208.022750] EXT4-fs (vdc): mounted filesystem 3ba8d33f-3159-45f5-b458-e44a8f44171f r/w with ordered data mode. Quota mode: journalled.

dmesg
(In reply to Thomas Blume from comment #5) > Created attachment 868971 [details] > dmesg After investigation by Jan, it turned out that the issue was caused by a corrupted system root filesystem. That, in turn affected the kernel module loading of the kernel module with quota format. After re-installation of the system, the issue is not reproducible anymore. So, this report was invalid, closing. |

After the scan is done it remounts the filesystem read-write. --< So, there seem to be 2 issues: 1. The error message when the fs is mounted rw indicates that there are no quot mount options, but they are: --> # quotacheck -ug /mnt1/ quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option. # # cat /proc/mounts | grep mnt1 /dev/vdc /mnt1 ext4 rw,relatime,quota,usrquota,grpquota,data=ordered 0 0 2. quotacheck apparently fails to remount the fs ro as stated in the manpage but it succeeds to remount the fs rw again after successful check: # umount /mnt1 && mount -o,ro /mnt1/ # cat /proc/mounts | grep mnt1 /dev/vdc /mnt1 ext4 ro,relatime,quota,usrquota,grpquota,data=ordered 0 0 quotacheck -ug /mnt1/ quotacheck: Your kernel probably supports ext4 quota feature but you are using external quota files.
