Hi, Gettings lots of nasty ext3 errors, as follows: attempt to access beyond end of device 03:06: rw=0, want=1989391900, limit=55167178 EXT3-fs error (device ide0(3,6)): ext3_free_branches: Read failure, inode=10092558, block=-1113264762 - several thousand of these in the course of a few seconds And lots of these: EXT3-fs error (device ide0(3,6)): ext3_free_blocks: Freeing blocks not in datazone - block = 3602131006, count = 1 And then finally (few seconds after the above): attempt to access beyond end of device 03:06: rw=0, want=274736132, limit=55167178 EXT3-fs error (device ide0(3,6)): ext3_free_branches: Read failure, inode=10092558, block=-1541928704 Assertion failure in do_get_write_access() at transaction.c:708: "handle->h_buffer_credits > 0" invalid operand: 0000 CPU: 0 EIP: 0010:[<c0156fb7>] Not tainted EFLAGS: 00010286 eax: 00000063 ebx: c57dd430 ecx: ccf36780 edx: ffffffff esi: 00000000 edi: c57dd430 ebp: 00000000 esp: c5c6bcd0 ds: 0018 es: 0018 ss: 0018 Process videoexe (pid: 984, stackpage=c5c6b000) Stack: c0232720 c02328e6 c0232700 000002c4 c0232921 cff47800 cfe7ee00 c57dd430 cff47894 cff47800 00000000 00000000 cff47800 cce1d760 c01570d8 cfe7ee00 c57dd430 00000000 00000000 c69799c0 cfe7ee00 c9d68820 c0150798 cfe7ee00 Call Trace: [<c01570d8>] [<c0150798>] [<c01570e0>] [<c01508fc>] [<c0150b98>] [<c0150a68>] [<c0150a68>] [<c0150a68>] [<c0150c79>] [<c0150f0b>] [<c01567b9>] [<c014ebad>] [<c014ec4c>] [<c014ecf3>] [<c014ec4c>] [<c0140287>] [<c013ea38>] [<c01382c6>] [<c01383a2>] [<c0106b87>] Code: 0f 0b 83 c4 14 8b 54 24 28 8b 42 04 48 8b 4c 24 28 89 41 04 That finally caused the thread that was running to lock solid and the machine had to be power-cycled. Sorry I can't put the oops through ksymoops - opportunity lost. The system is running stock 2.4.18 build patched for lm-sensors Hardware is: Abit ST6 Motherboard + 256Meg + 1.2Gig Celeron 2x80 gig harddisks (make unknown !) 2xbttv capture cards 1xnetgear ethernet card The machine normally runs at around 40% idle, but is doing lot of disk writes, essentially its capturing video and writing it to disk (into 2 large partitions, 50 gig each) and its possible that one of the partitions was fullish (> 95%) - but not totally full. Strangely the same sort of things has happened on another customers site - but that one is now not rebooting (!!!) and so I cannot retrieve any logs (as I have to do it via modem) - it has a very similar spec. I've trawled thought linux.kernel and this mailing list and I've read lots of 2.4.18 + ext3 problem reports, I've also seen a few things about 2.4.19 and so was thinking about trying a site with 2.4.20-pre11. Obviously its possible that a hardware failure has occurred, but same problem on two sites?. I'd appreciate it if anyone could give me some idea of what might have happened and what would be a good strategy to stop this from happening in the future. I've got a system on test in the office at the moment and we'll be dragging a failed one back from site to do more testing on so I might be able to give more details later. Any help would be gratefully appreciated. Cheers, Glen _______________________________________________ Ext3-users@redhat.com https://listman.redhat.com/mailman/listinfo/ext3-users
