[LU-7094] object UID not being set correctly for non-root user

Duplicate — Thu, 15 Oct 2015 17:39:26 +0000

Running "rsync -a /etc $MOUNT" to populate a filesystem and then run LFSCK against it, I see that the one file in my /etc not owned by root is not getting the UID set properly, and LFSCK has to fix it:

# lctl set_param printk=+lfsck
# lctl lfsck_start -M testfs-MDT0000 -t all -A
<wait until done>
# lctl get_param mdd.*testfs-*.lfsck_* | grep "repaired.*: [1-9]"
repaired_inconsistent_owner: 1
# dmesg | grep repaired
Lustre: 19941:0:(lfsck_layout.c:3076:lfsck_layout_repair_owner()) testfs-MDT0001-osd: layout LFSCK assistant repaired inconsistent file owner for: parent [0x240000403:0x257:0x0], child [0x280000400:0x3c:0x0], OST-index 0, stripe-index 0, old owner 0/10000, new owner 10000/10000: rc = 1
# lfs fid2path /mnt/testfs [0x240000403:0x257:0x0]
/mnt/testfs//etc3/etc/bash_completion.d/msm
# ls -ln /etc/bash_completion.d/msm
8 -rw-rw-r-- 1 10000 10000 7236 Apr 22  2014 /etc/bash_completion.d/msm
# find /etc ! -uid 0 | less
/etc/bash_completion.d/msm
# find /etc ! -gid 0 | less
/etc/mtab.fuselock
/etc/pam.d/atd
/etc/bash_completion.d/msm
/etc/aliases.db
/etc/dumpdates
/etc/ntp/crypto

This is 100% repeatable (i.e. lfsck will find and fix this one file each time it is copied), and not complain about any of the files with GID != 0. I suspect this should be breaking quota for non-root users.
