Description of problem: On one machine with nested mounts (SELinux permissive), updatedb never explores the top mounted filesystem unless specifically requested to. In more detail: - RHEL6.7, with all of the latest updates as of today (20160318). - /export/home mounted as ext4. - /export/home/shared mounted as vxfs and not excluded/pruned. 1) # locate /export/home/shared returns only the directory, not the content. 2) # updatedb -U /export/home/shared makes locate display the right things. 3) # updatedb -U /export/home makes locate skip the content underneath /export/home/shared (like #1) Problem exhibits itself with: [root@daltigoth ~]# updatedb -U /export/home/shared [root@daltigoth ~]# locate /|grep export/home/shared|wc -l 578795 [root@daltigoth ~]# updatedb -U /export/home [root@daltigoth ~]# locate /|grep export/home/shared|wc -l 1 (should return 578795) [root@daltigoth ~]# updatedb -U / [root@daltigoth ~]# locate /|grep export/home/shared|wc -l 1 (should return 578795) [root@daltigoth ~]# grep vxfs /etc/updatedb.conf [root@daltigoth ~]# grep /shared /etc/updatedb.conf PRUNEPATHS = "/afs /media /net /sfs /tmp /udev /var/cache/ccache /var/spool/cups /var/spool/squid /var/tmp /shared/movies1" Version-Release number of selected component (if applicable): [root@daltigoth ~]# rpm -q mlocate mlocate-0.22.2-6.el6.x86_64 [root@daltigoth ~]# df -h /export/home Filesystem Size Used Avail Use% Mounted on /dev/mapper/rootdg-lv_home 457G 336G 99G 78% /export/home [root@daltigoth ~]# df -h /export/home/shared Filesystem Size Used Avail Use% Mounted on /dev/vx/dsk/local01dg/staging1_lv 1.2T 1.1T 76G 94% /export/home/shared [root@daltigoth ~]# mount -v|grep /export/home /dev/mapper/rootdg-lv_home on /export/home type ext4 (rw,noatime) /dev/vx/dsk/local01dg/staging1_lv on /export/home/shared type vxfs (rw,delaylog,largefiles,noatime,ioerror=mwdisable) /export/home on /net/imladris/export/home type none (rw,bind) /export/home/shared on /net/imladris/export/home/shared type none (rw,bind) How reproducible: 100% updatedb -U /export/home/shared vs: updatedb -U /export/home Steps to Reproduce: 1. 2. 3.
