Hi Pranith,
Many thanks for your suggestive reply.
The gluster version I used is 3.2.7. It seems the same problem. However, I
still don't know what actions cause client to send "protocol_client_reopen" to
server side. And I failed to reproduce the bug each time.
I checked the source code, it looks like lock problem.
/* Delay notifying CHILD_UP to parents
until all locks are recovered */
if (count > 0) {
gf_log (this->name, GF_LOG_INFO,
"%d fds open - Delaying child_up until they are
re-opened",
count);
Cheers,
Qiulan

Dear all,
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.
For example: ff_2
First, the new created file: ff_2
[root@test02 ~]# ll /testfs/mydir
total 50941
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_3
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_4
-rw-rw-r-- 1 test test 0 Jan 12 11:38 ff_1
-rw-rw-r-- 1 test test 5242880 Jan 13 00:43 ff_2
From server side, we have 2 bricks and we can see the ff_2 status:
brick1:
-rw-rw-r-- 1 test test 0 Jan 12 11:38 ff_1
---------T 1 test test 0 Jan 13 00:43 ff_2
brick2:
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_3
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_4
-rw-rw-r-- 1 test test 5242880 Jan 13 00:43 ff_2
After we restart gluterd service, we can see the ownership of ff_2 was changed
to root:root.
brick1:
-rw-rw-r-- 1 test test 0 Jan 12 11:38 ff_1
---------T 1 test test 0 Jan 13 00:43 ff_2
brick2:
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_3
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_4
-rw-rw-r-- 1 root root 5242880 Jan 13 00:43 ff_2
Then, we can get the file list on client side:
[root@test02 ~]# ll /testfs/mydir
total 50941
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_3
-rw-rw-r-- 1 test test 5242880 Jan 12 11:31 f_4
-rw-rw-r-- 1 test test 0 Jan 12 11:38 ff_1
-rw-rw-r-- 1 root root 5242880 Jan 13 00:43 ff_2
this problem has stucked me for days. Could someone give us tips, thank you
very much.
Cheers,
Qiulan
