When using ocfs2 on 3.17.4 (i have seen this since 3.14) and
mount-bind ocfs2 to a lxc-container, when postfix inside the lxc tries to
write mails to ocfs2 dir using virtual transport, kernel says:
[ 3812.352564] (virtual,25186,3):ocfs2_link:812 ERROR: status = -2
In 3.12 this did _NOT_ happen.
This code (from postfix virtual transport program 'virtual' seems to cause the
kernel message:
newfile = concatenate(newdir, STR(buf), (char *) 0);
if ((mail_copy_status = mail_copy(COPY_ATTR(state.msg_attr),
dst, copy_flags, "\n",
why)) == 0) {
if (sane_link(tmpfile, newfile) < 0
&& (errno != ENOENT
|| (make_dirs(curdir, 0700), make_dirs(newdir, 0700)) < 0
|| sane_link(tmpfile, newfile) < 0)) {
dsb_simple(why, mbox_dsn(errno, "4.2.0"),
"create maildir file %s: %m", newfile);
mail_copy_status = MAIL_COPY_STAT_WRITE;
}
}
if (unlink(tmpfile) < 0)
msg_warn("remove %s: %m", tmpfile);
}
/* sane_link - sanitize link() error returns */
int sane_link(const char *from, const char *to)
{
const char *myname = "sane_link";
int saved_errno;
struct stat from_st;
struct stat to_st;
/*
* Normal case: link() succeeds.
*/
if (link(from, to) >= 0)
return (0);
/*
* Woops. Save errno, and see if the error is an NFS artefact. If it is,
* pretend the error never happened.
*/
saved_errno = errno;
if (stat(from, &from_st) >= 0 && stat(to, &to_st) >= 0
&& from_st.st_dev == to_st.st_dev
&& from_st.st_ino == to_st.st_ino) {
msg_info("%s(%s,%s): worked around spurious NFS error",
myname, from, to);
return (0);
}
/*
* Nope, it didn't. Restore errno and report the error.
*/
errno = saved_errno;
return (-1);
}
This seems like a regression to me since this used to work in 3.12.33
After the error, the mail is in /tmp/ of the mailbox but not moved to the /new/
dir. Also, courier-imapd fails to move mails from inbox to subfolders with the
same error message, leaving the mails to move in /tmp/ so i suspect
sane_link(tempfile, newfile) to have a problem within the current ocfs2_link().
[ 3337.084292] (imapd,5766,5):ocfs2_link:812 ERROR: status = -2
Please help!
