Hi,

we noticed the following ceph errors in the kernel messages (dmesg -T):

[Tue Jul  9 11:59:24 2024] ceph: ceph_fill_inode 10003683698.fffffffffffffffe BAD symlink size 0

Is this something that we should be worried about?

We are currently trying to identify the inode/file using:

# find /data -inum 10003683698 -printf "%i %p\n"

Could deleting the inode fix the issue? If not what can we do?

find did not return anything. The error keeps showing up , has someone an idea?

Hello,
The inode number in the error message is in hexadecimal while "find" expects a decimal number.

You can ask the MDS instead of using "find":
     ceph tell 'mds.*' dump inode 10003683698 | grep '"path"'

There is a more complicated way to find the name if the inode is not in the MDS cache (https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/thread/MSB5TIG42XAFNG2CKILY5DZWIMX6C5CO/)

Thanks a lot again. The method described in the linked posting worked. We deleted the symlink, we will keep an eye on it.

Cheers
   Dietmar
