Hi, I tried today to set up cryptsetup luks on a logical volume (size: 931 GB), but crypsetup died with a lot of kernel errors. server did NOT hang up. what happened: 1. I have 3x 500GB disks 2. These disks are in raid5 3. I set up LVM2 over this raid5 4. I run: cryptsetup -y luksFormat /dev/vg0/lv0_raid After confirming deletion of all data with YES, I got these errors (copy from syslog): -------------------------------------------------------------- Mar 2 04:57:28 server5 kernel: RAID5 conf printout: Mar 2 04:57:28 server5 kernel: --- rd:3 wd:3 Mar 2 04:57:28 server5 kernel: disk 0, o:1, dev:sdc1 Mar 2 04:57:28 server5 kernel: disk 1, o:1, dev:sdd1 Mar 2 04:57:28 server5 kernel: disk 2, o:1, dev:sde1 Mar 2 08:27:08 server5 kernel: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 Mar 2 08:27:08 server5 kernel: printing eip: Mar 2 08:27:08 server5 kernel: c014ec03 Mar 2 08:27:08 server5 kernel: *pde = 00000000 Mar 2 08:27:08 server5 kernel: Oops: 0000 [#1] Mar 2 08:27:08 server5 kernel: PREEMPT Mar 2 08:27:08 server5 kernel: Modules linked in: nvidia(P) Mar 2 08:27:08 server5 kernel: CPU: 0 Mar 2 08:27:08 server5 kernel: EIP: 0060:[<c014ec03>] Tainted: P VLI Mar 2 08:27:08 server5 kernel: EFLAGS: 00010286 (2.6.20.1 #2) Mar 2 08:27:08 server5 kernel: EIP is at mempool_free+0x13/0xc0 Mar 2 08:27:08 server5 kernel: eax: f7787fc4 ebx: f793f440 ecx: 00000001 edx: 00000000 Mar 2 08:27:08 server5 kernel: esi: 00000000 edi: f7787fc4 ebp: f48b3a80 esp: f7f53e3c Mar 2 08:27:08 server5 kernel: ds: 007b es: 007b ss: 0068 Mar 2 08:27:08 server5 kernel: Process md3_raid5 (pid: 1051, ti=f7f52000 task=f7e74550 task.ti=f7f52000) Mar 2 08:27:08 server5 kernel: Stack: f48b3a80 f793f440 f7787fc4 00000000 c03ef983 00000000 f793f440 00000200 Mar 2 08:27:08 server5 kernel: c03ef8f0 00000000 c019096d f7f53e84 00000282 00000000 00000000 e847798c Mar 2 08:27:08 server5 kernel: 00000000 00000000 e81d7c08 c03e7eb4 00000000 f793f1c0 00000000 00000000 Mar 2 08:27:08 server5 kernel: Call Trace: Mar 2 08:27:08 server5 kernel: [<c03ef983>] crypt_endio+0x93/0xb0 Mar 2 08:27:08 server5 kernel: [<c03ef8f0>] crypt_endio+0x0/0xb0 Mar 2 08:27:08 server5 kernel: [<c019096d>] bio_endio+0x5d/0xa0 Mar 2 08:27:08 server5 kernel: [<c03e7eb4>] dec_pending+0x64/0x120 Mar 2 08:27:08 server5 kernel: [<c03e7ff6>] clone_endio+0x86/0xe0 Mar 2 08:27:08 server5 kernel: [<c03d2df7>] handle_stripe5+0x1017/0x1660 Mar 2 08:27:08 server5 kernel: [<c03d625e>] raid5d+0xfe/0x190 Mar 2 08:27:08 server5 kernel: [<c03e2d4a>] md_thread+0x3a/0x120 Mar 2 08:27:08 server5 kernel: [<c0132550>] autoremove_wake_function+0x0/0x50 Mar 2 08:27:08 server5 kernel: [<c0132550>] autoremove_wake_function+0x0/0x50 Mar 2 08:27:08 server5 kernel: [<c03e2d10>] md_thread+0x0/0x120 Mar 2 08:27:08 server5 kernel: [<c01320b4>] kthread+0xa4/0xe0 Mar 2 08:27:08 server5 kernel: [<c0132010>] kthread+0x0/0xe0 Mar 2 08:27:08 server5 kernel: [<c01033cf>] kernel_thread_helper+0x7/0x18 Mar 2 08:27:08 server5 kernel: ======================= Mar 2 08:27:08 server5 kernel: Code: a7 b8 88 13 00 00 89 f6 e8 bb 65 35 00 eb db 31 c0 e9 34 ff ff ff 89 f6 83 ec 10 89 7 4 24 08 89 7c 24 0c 89 d6 89 5c 24 04 89 c7 <8b> 02 39 42 04 7d 27 9c 5b fa 89 e0 25 00 e0 ff ff ff 40 14 8b Mar 2 08:27:08 server5 kernel: EIP: [<c014ec03>] mempool_free+0x13/0xc0 SS:ESP 0068:f7f53e3c Mar 2 08:27:50 server5 gdm[3436]: Error reinitilizing server Mar 2 08:27:53 server5 kernel: <7>spurious 8259A interrupt: IRQ15. ---------------------------------------------- I created on the same server smaller encrypted partitions over raid0 without any problems. Is there a problem with big partitions and cryptsetup? Or is it my kernel (2.6.20.1). Device-mapper version is 1.02.09. Thanks M.
