I didn't notice any issues in a test VM and therefore decided to update my laptop as well. So far I've experienced three panics/reboots/freezes that I suspect might be caused by the upgrade from zfs-2.1.6-FreeBSD_g6a6bd4939 to zfs-2.1.7-FreeBSD_g21bd76613. They all occurred while I was syncing ZFS datasets with zogftw [0]. Unfortunately I only have one backtrace so I can't say for sure that the other times where ZFS related as well: Unread portion of the kernel message buffer: panic: VERIFY3(0 =3D=3D zap_remove(mos, dsobj, spa_feature_table[f].fi_guid= , tx)) failed (0 =3D=3D 2) cpuid =3D 3 time =3D 1673033419 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00dc686= 8a0 vpanic() at vpanic+0x151/frame 0xfffffe00dc6868f0 spl_panic() at spl_panic+0x3a/frame 0xfffffe00dc686950 dsl_dataset_deactivate_feature_impl() at dsl_dataset_deactivate_feature_imp= l+0xe6/frame 0xfffffe00dc6869a0 dsl_dataset_clone_swap_sync_impl() at dsl_dataset_clone_swap_sync_impl+0x13= 5/frame 0xfffffe00dc686ad0 dmu_recv_end_sync() at dmu_recv_end_sync+0x2a2/frame 0xfffffe00dc686b30 dsl_sync_task_sync() at dsl_sync_task_sync+0xb4/frame 0xfffffe00dc686b60 dsl_pool_sync() at dsl_pool_sync+0x42b/frame 0xfffffe00dc686be0 spa_sync() at spa_sync+0xb00/frame 0xfffffe00dc686e10 txg_sync_thread() at txg_sync_thread+0x281/frame 0xfffffe00dc686ef0 fork_exit() at fork_exit+0x7e/frame 0xfffffe00dc686f30 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe00dc686f30 --- trap 0x3, rip =3D 0xffffffff80659b3f, rsp =3D 0, rbp =3D 0xffffffff818f= 4fa0 --- mi_startup() at mi_startup+0xdf/frame 0xffffffff818f4fa0 swapper() at swapper+0x69/frame 0xffffffff818f4ff0 btext() at btext+0x22 Uptime: 6m35s Dumping 1098 out of 8050 MB:..2%..11%..21%..31%..41%..51%..62%..72%..81%..9= 1% __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:55 55 __asm("movq %%gs:%P1,%0" : "=3Dr" (td) : "n" (offsetof(struct pcpu, (kgdb) where #0 __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:55 #1 dump_savectx () at /usr/src/sys/kern/kern_shutdown.c:394 #2 0xffffffff806cda18 in dumpsys (di=3D0x0) at /usr/src/sys/x86/include/du= mp.h:87 #3 doadump (textdump=3D1) at /usr/src/sys/kern/kern_shutdown.c:423 #4 kern_reboot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:497 #5 0xffffffff806cde9e in vpanic (fmt=3D, ap=3Dap@entry=3D0x= fffffe00dc686930) at /usr/src/sys/kern/kern_shutdown.c:930 #6 0xffffffff81278e3a in spl_panic (file=3D, func=3D, line=3D, fmt=3D) at /usr/src/sys/contri= b/openzfs/module/os/freebsd/spl/spl_misc.c:107 #7 0xffffffff813001e6 in dsl_dataset_deactivate_feature_impl (ds=3Dds@entr= y=3D0xfffff80019a60000, f=3Df@entry=3DSPA_FEATURE_USEROBJ_ACCOUNTING, tx=3D= tx@entry=3D0xfffff80191ace200) at /usr/src/sys/contrib/openzfs/module/zfs/dsl_dataset.c:1116 #8 0xffffffff81304cb5 in dsl_dataset_clone_swap_sync_impl (clone=3D0xfffff= 8018fc79000, origin_head=3D, tx=3D, tx@entry=3D0x= fffff80191ace200) at /usr/src/sys/contrib/openzfs/module/zfs/dsl_dataset.c:= 4083 #9 0xffffffff812eaff2 in dmu_recv_end_sync (arg=3D0xfffffe00d91366b8, tx= =3D0xfffff80191ace200) at /usr/src/sys/contrib/openzfs/module/zfs/dmu_recv.= c:3233 #10 0xffffffff8132c254 in dsl_sync_task_sync (dst=3D0xfffffe00d91364a8, tx= =3Dtx@entry=3D0xfffff80191ace200) at /usr/src/sys/contrib/openzfs/module/zf= s/dsl_synctask.c:248 #11 0xffffffff8131ea6b in dsl_pool_sync (dp=3Ddp@entry=3D0xfffff801eabad800= , txg=3Dtxg@entry=3D3576757) at /usr/src/sys/contrib/openzfs/module/zfs/dsl= _pool.c:847 #12 0xffffffff81353930 in spa_sync_iterate_to_convergence (spa=3D0xfffffe00= da149000, tx=3D0xfffff80191e73400) at /usr/src/sys/contrib/openzfs/module/z= fs/spa.c:9069 #13 spa_sync (spa=3Dspa@entry=3D0xfffffe00da149000, txg=3Dtxg@entry=3D35767= 57) at /usr/src/sys/contrib/openzfs/module/zfs/spa.c:9287 #14 0xffffffff81368281 in txg_sync_thread (arg=3Darg@entry=3D0xfffff801eaba= d800) at /usr/src/sys/contrib/openzfs/module/zfs/txg.c:591 #15 0xffffffff80689fde in fork_exit (callout=3D0xffffffff81368000 , arg=3D0xfffff801eabad800, frame=3D0xfffffe00dc686f40) at /usr/src= /sys/kern/kern_fork.c:1093 #16 #17 mi_startup () at /usr/src/sys/kern/init_main.c:322 #18 0xffffffff80a1e439 in swapper () at /usr/src/sys/vm/vm_swapout.c:755 #19 0xffffffff802f8722 in btext () at /usr/src/sys/amd64/amd64/locore.S:80 Has anyone else seen this? I've seen it with three different ZFS pools and I think the pools are fine. The laptop only supports USB2 so scrubbing the pools takes days which is why I didn't do it yet. I have no reliable way to reproduce the issue yet. Running zogftw sync again after rebooting worked in all three cases.
