Mounting a nfs dir under UML with option soft and stopping nfs - service at the host system, shows wrong block size, eg: normal behaviour (n22_uml is the UML sytem, n22_tun the host) : n22_uml ~ # df /mnt/nfs/n22_tmp Filesystem 1K-blocks Used Available Use% Mounted on n22_tun:/tmp 14011712 10646784 2653184 81% /mnt/nfs/n22_tmp Now I stop nfs at n22_tun: n22 ~ # /etc/init.d/nfs stop * Stopping NFS mountd ... [ ok ] * Stopping NFS daemon ... [ ok ] * Unexporting NFS directories ... [ ok ] * Stopping NFS statd ... Ang got finally under UML: n22_uml ~ # df /mnt/nfs/n22_tmp Filesystem 1K-blocks Used Available Use% Mounted on n22_tun:/tmp 77371252437321868667518976 0 77371252437321868667518976 0% /mnt/nfs/n22_tmp Here the exports - file from the host: n22 ~ # cat /etc/exports # /etc/exports: NFS file systems being exported. See exports(5). /tmp n22_uml(rw,sync,all_squash) and the appropriate fstab - entry under UML: n22_uml ~ # grep n22_tmp /etc/fstab n22_tun:/tmp /mnt/nfs/n22_tmp nfs soft 0 0 I updated the host system as well as the UML (emerge sync && emerge --newuse --update --ask --verbose --deep --tree world) before I reproduced this bug. Maybe there is a relation to bug #104351 ?
