Description
Seeing frequent MDS daemons crashes in a multi-active setup. The crashes often coincide with inode migrations, but not sure that is related.
I requested coredumps for these crashes. Log of one MDS is attached.

If you have coredump, please use gdb to print value of 'state'. Besides ceph was compiled from 8881d33957b54b101eae9c7627b351af10e87ee8. I can't it in upstream ceph repository

Sorry this commit comes from github.com/SUSE/ceph
The this build corresponds to commit daf0990c19c89267ea10c40b9c7a48bea49a3d1b upstream.
Will update with coredumps as soon as I get them.

Lock state is SYNC. I checked code, can't figure out why. could you try reproducing this with debug_mds=10.

Because currently the put_xlock() do not allow putting the Locker in LOCK_PREXLOCK state:
416 void put_xlock() {
417 ceph_assert(state == LOCK_XLOCK || state == LOCK_XLOCKDONE ||
418 state == LOCK_XLOCKSNAP || state == LOCK_LOCK_XLOCK ||
419 state == LOCK_LOCK || /* if we are a leader of a peer */
420 state == LOCK_PREXLOCK ||
421 is_locallock());
422 --more()->num_xlock;
423 parent->put(MDSCacheObject::PIN_LOCK);
424 if (more()->num_xlock == 0) {
425 more()->xlock_by.reset();
426 more()->xlock_by_client = -1;
427 try_clear_more();
428 }
429 }
IMO we should allow it here.

There is another different case also causing the same ceph_assert failure:
The ilink locker state was LOCK_SYNC instead:
