<DIV> </DIV>
<DIV> I have encountered a strange problem
that the ownership of linkto file was changed to root:root after we reboot
server. And I reproduced the problem many times.</DIV>
<DIV> </DIV>
<DIV>For example: ff_2</DIV>
<DIV> </DIV>
<DIV>First, the new created file: ff_2</DIV>
<DIV> </DIV>
<DIV>
<DIV>[root@test02 ~]# ll /testfs/mydir</DIV>
<DIV>total 50941</DIV>
<DIV>-rw-rw-r-- 1 test
test 5242880 Jan 12 11:31 f_3</DIV>
<DIV>-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_4</DIV>
<DIV>-rw-rw-r-- 1 test test

<DIV>-<FONT color=#ff0000>rw-rw-r-- 1 test test
5242880 Jan 13 00:43 ff_2</FONT></DIV>
<DIV> </DIV>
<DIV>From server side, we have 2 bricks and we can see the ff_2
status:</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>
<DIV>brick1:</DIV>
<DIV> </DIV>
<DIV>-rw-rw-r-- 1 test test
0 Jan 12 11:38 ff_1</DIV>
<DIV><FONT color=#ff0000>---------T 1 test test
0 Jan 13 00:43 ff_2</FONT></DIV>
<DIV> </DIV>
<DIV>
<DIV>brick2:</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>-rw-rw-r-- 1 test test
5242880 Jan 12 11:31 f_3</DIV>
<DIV>-rw-rw-r-- 1 test test

<DIV><FONT color=#ff0000>-rw-rw-r-- 1 test test
5242880 Jan 13 00:43 ff_2</FONT></DIV>
<DIV> </DIV>
<DIV>After we restart gluterd service, we can see the ownership of ff_2 was
changed to root:root.</DIV></DIV></DIV>
<DIV> </DIV></DIV>
<DIV>
<DIV>brick1:</DIV>
<DIV> </DIV>
<DIV>-rw-rw-r-- 1 test test
0 Jan 12 11:38 ff_1</DIV>
<DIV><FONT color=#ff0000>---------T 1 test test

<DIV> </DIV>
<DIV>

<DIV> </DIV>
<DIV> </DIV>
<DIV>-rw-rw-r-- 1 test test

<DIV>-rw-rw-r-- 1 test test

<DIV><FONT color=#ff0000>-rw-rw-r-- 1 root root
5242880 Jan 13 00:43 ff_2</FONT></DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Then, we can get the file list on client side:</DIV></DIV></DIV>
<DIV> </DIV>
<DIV>
<DIV>[root@test02 ~]# ll /testfs/mydir</DIV>
<DIV>total 50941</DIV>
<DIV>-rw-rw-r-- 1 test

5242880 Jan 13 00:43 ff_2</FONT></DIV>
<DIV> </DIV>
