Re: [MDS crash / ceph_assert failure] CephFS MDS crash on Reef 18.2.2 (Filer::_probed assertion)
Hi, thanks for sharing the logs. I see lines: Jan 21 19:52:21 s11 bash[3097096]: debug 2026-01-21T19:52:21.946+0000 7f6cd7e74700 -1 log_channel(cluster) log [ERR] : bad backtrace on directory inode 0x100013897dd Jan 21 19:52:21 s11 bash[3097096]: debug 2026-01-21T19:52:21.948+0000 7f6cd7e74700 -1 log_channel(cluster) log [ERR] : bad backtrace on directory inode 0x1000139903b Jan 21 19:52:21 s11 bash[3097096]: debug 2026-01-21T19:52:21.948+0000 7f6cd7e74700 -1 log_channel(cluster) log [ERR] : bad backtrace on directory inode 0x10001399315 this seems to be hinting that the metadata recovery was inconsistent, this doesn't directly translate into the root cause but this _may_ have lead to MDS sending wrong input (possibly the file layout) while calling probe() in RecoveryQueue::_start making use of the "projected inode" that passes on the inode number, the file layout and the max file size to filer.probe() which is calling the Stripper::file_to_extents to calculate the extents and their compuated sizes should've been more than what the object size is returned by objecter->stat(). If you can set the debug mds to 20, I think it should reveal what the values of the object extent was calculated by Stripper code and the file size returned by the OSD. *Dhairya Parmar* Software Engineer, CephFS On Sat, Jan 31, 2026 at 11:40 PM Андрей Муханов <mukhanovster@gmail.com> wrote:
Hi Dhairya, The debug logs were included in my original email, but they seem to have disappeared from the mailing list. Please find them here.
To my understanding, yes, this appears to be the same issue described in the link you provided, although the root cause may be different.
