i seem to have run into an oops described in the archives -- in particular this thread from last year: https://www.redhat.com/archives/linux-lvm/2004-January/msg00110.html has there been any further work on this? any success stories for the #2 patch mentioned in the above thread? my system is running 2.4.29 + linux-2.4.22-VFS-lock.patch ... it's a dual xeon w/hyperthreading. i've been using snapshots for over a year for nightly backups and this is the first time i've run into the oops. thanks -dean Mar 16 03:31:19 twinlark kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000004 Mar 16 03:31:19 twinlark kernel: printing eip: Mar 16 03:31:19 twinlark kernel: c021f30c Mar 16 03:31:19 twinlark kernel: *pde = 00000000 Mar 16 03:31:19 twinlark kernel: Oops: 0002 Mar 16 03:31:19 twinlark kernel: CPU: 3 Mar 16 03:31:19 twinlark kernel: EIP: 0010:[lvm_snapshot_remap_block+220/256] Not tainted Mar 16 03:31:19 twinlark kernel: EFLAGS: 00010202 Mar 16 03:31:19 twinlark kernel: eax: f8a3dde0 ebx: f8d36800 ecx: f8a31000 edx: 00000000 Mar 16 03:31:19 twinlark kernel: esi: 00010180 edi: 00000001 ebp: 00000903 esp: e1483ce0 Mar 16 03:31:19 twinlark kernel: ds: 0018 es: 0018 ss: 0018 Mar 16 03:31:19 twinlark kernel: Process qmail-smtpd (pid: 18415, stackpage=e1483000) Mar 16 03:31:19 twinlark kernel: Stack: 00000038 00000903 00000000 f7ba9600 e94e5c00 e94e5d70 00010000 c021bb28 Mar 16 03:31:19 twinlark kernel: e1483d34 e1483d2c 00010180 e94e5c00 00000001 c01c7662 00000001 f7ba9770 Mar 16 03:31:19 twinlark kernel: f750c000 00010180 00000000 000101b8 000101b8 09030903 00003a00 f7535980 Mar 16 03:31:19 twinlark kernel: Call Trace: [lvm_map+408/1136] [submit_bh+82/256] [lvm_make_request_fn+23/48] [generic_make_request+228/320] [submit_bh+82/256] Mar 16 03:31:19 twinlark kernel: [__refile_buffer+86/112] [sync_page_buffers+168/176] [try_to_free_buffers+331/368] [shrink_cache+827/1040] [shrink_caches+74/96] [try_to_free_pages_zone+98/240] Mar 16 03:31:19 twinlark kernel: [balance_classzone+77/496] [__alloc_pages+376/640] [filemap_nopage+494/560] [filemap_nopage+0/560] [do_no_page+330/640] [handle_mm_fault+117/256] Mar 16 03:31:19 twinlark kernel: [do_page_fault+968/1397] [do_mmap_pgoff+874/1488] [old_mmap+272/304] [filp_close+143/208] [do_page_fault+0/1397] [error_code+52/60] Mar 16 03:31:19 twinlark kernel: Mar 16 03:31:19 twinlark kernel: Code: 89 42 04 8b 03 89 48 04 89 01 89 59 04 89 0b 89 ca eb 9f b8 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
