A serious problem of mds I think.
Anyone to fix it?
Regards.

Hi,
looking at the code, and running with debug mds = 10 it looks like I have an inode with negative link count.

I guess "nl" stands for number of links.
The code in StrayManager.cc checks for:
if (in->inode.nlink == 0) { ... }
else {
eval_remote_stray(dn, NULL);
}
void StrayManager::eval_remote_stray(CDentry *stray_dn, CDentry *remote_dn)
{
...
assert(stray_in->inode.nlink >= 1);
...
}
So if my link count is indeed -1 ceph will die here.
The question is: how can I get rid of this inode?
