Hi! Short overview: - Had CURRENT system from around September - Upgrade on the 23th of December - crashes in ZFS, see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261538 for details - Reinstalled from scratch with new SSDs drives from https://download.freebsd.org/snapshots/amd64/amd64/ISO-IMAGES/15.0/ freebsd-openzfs-amd64-2020081900-memstick.img.xz - Had one crash with sysctl -a https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276039 - Still see crashes with ZFS (and other) when using poudriere to build ports.
Problem: I happen to run in several cases of crashes in ZFS, some of them fatal (zpool non-recoverable). The latest was: panic: VERIFY(BP_GET_DEDUP(bp)) failed cpuid = 29 time = 1704050745 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe02def538c0 vpanic() at vpanic+0x131/frame 0xfffffe02def539f0 spl_panic() at spl_panic+0x3a/frame 0xfffffe02def53a50 dsl_livelist_iterate() at dsl_livelist_iterate+0x2de/frame 0xfffffe02def53b30 bpobj_iterate_blkptrs() at bpobj_iterate_blkptrs+0x235/frame 0xfffffe02def53bf0 bpobj_iterate_impl() at bpobj_iterate_impl+0x16e/frame 0xfffffe02def53c80 dsl_process_sub_livelist() at dsl_process_sub_livelist+0x5c/frame 0xfffffe02def53d00 spa_livelist_delete_cb() at spa_livelist_delete_cb+0xf6/frame 0xfffffe02def53ea0 zthr_procedure() at zthr_procedure+0xa5/frame 0xfffffe02def53ef0 fork_exit() at fork_exit+0x82/frame 0xfffffe02def53f30 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe02def53f30 --- trap 0x85baac33, rip = 0xdfda59b01bda59f, rsp = 0xaaca3ed7a68a3ed3, rbp = 0x16f512f91ab512fd --- before I had to nuke that pool and restart... I already have vfs.zfs.dmu_offset_next_sync=0 which is supposed to disable block-cloning. Does anyone else see this with recent versions or is it just me ? -- p...@freebsd.org +49 171 3101372 Now what ?
