RobJ I came across this while experimenting with my 2nd server over the last couple of days. Since it has smaller drives, the parity check doesn't take as long. I might try a 750GB drive next to see what happens. Strange problem....

bjp999 recommended that I post the problem here about getting error messages with more then 15 drives (the 1st post is in the software area). Here is the error I get in the syslog: May 15 07:13:00 Tower2 kernel: BUG: unable to handle kernel paging request at 6d614e8e May 15 07:13:00 Tower2 kernel: IP: [<f82e525c>] xor_block+0x76/0x84 [md_mod] May 15 07:13:00 Tower2 kernel: *pdpt = 0000000002de0001 *pde = 0000000000000000 May 15 07:13:00 Tower2 kernel: Oops: 0000 [#1] SMP May 15 07:13:00 Tower2 kernel: last sysfs file: /sys/devices/pci0000:00/0000:00:1c.3/0000:03:00.0/ho st0/target0:4:0/0:4:0:0/block/sda/stat May 15 07:13:00 Tower2 kernel: Modules linked in: md_mod ata_piix sata_promise e1000 sata_sil24 liba ta May 15 07:13:00 Tower2 kernel: May 15 07:13:00 Tower2 kernel: Pid: 1906, comm: unraidd Not tainted (2.6.29.1-unRAID #2) May 15 07:13:00 Tower2 kernel: EIP: 0060:[<f82e525c>] EFLAGS: 00010202 CPU: 0 May 15 07:13:00 Tower2 kernel: EIP is at xor_block+0x76/0x84 [md_mod] May 15 07:13:00 Tower2 kernel: EAX: 00001000 EBX: 6d614e76 ECX: c2890000 EDX: c28fb000 May 15 07:13:00 Tower2 kernel: ESI: c2893000 EDI: c28fb000 EBP: f63cbefc ESP: f63cbedc May 15 07:13:00 Tower2 kernel: DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 May 15 07:13:00 Tower2 kernel: Process unraidd (pid: 1906, ti=f63ca000 task=f6fff740 task.ti=f63ca00 0) May 15 07:13:00 Tower2 kernel: Stack: May 15 07:13:00 Tower2 kernel: c2892000 c2893000 c2868000 6d614e76 00001000 00000001 c28f11e0 c28f1 3a0 May 15 07:13:00 Tower2 kernel: f63cbf3c f82e7474 00000001 00000005 00000011 00001000 00001000 f5aab 000 May 15 07:13:00 Tower2 kernel: c28fb000 c2890000 c2892000 c2893000 c2868000 c28f1910 00000000 c28f1 1e0 May 15 07:13:00 Tower2 kernel: Call Trace: May 15 07:13:00 Tower2 kernel: [<f82e7474>] ? compute_parity+0x101/0x2cc [md_mod] May 15 07:13:00 Tower2 kernel: [<f82e7ff0>] ? handle_stripe+0x8cc/0xc5a [md_mod] May 15 07:13:00 Tower2 kernel: [<c0344f57>] ? schedule+0x5e3/0x63c May 15 07:13:00 Tower2 kernel: [<f82e8804>] ? unraidd+0x9e/0xbc [md_mod] May 15 07:13:00 Tower2 kernel: [<f82e8766>] ? unraidd+0x0/0xbc [md_mod] May 15 07:13:00 Tower2 kernel: [<c01301bc>] ? kthread+0x3b/0x63 May 15 07:13:00 Tower2 kernel: [<c0130181>] ? kthread+0x0/0x63 May 15 07:13:00 Tower2 kernel: [<c01035db>] ? kernel_thread_helper+0x7/0x10 May 15 07:13:00 Tower2 kernel: Code: f8 8b 71 0c 89 45 ec 75 13 56 8b 45 f0 89 d1 53 8b 5d ec 89 fa ff 53 14 5a 59 eb 15 ff 71 10 89 d1 8b 45 f0 89 fa 56 53 8b 5d ec <ff> 53 18 83 c4 0c 8d 65 f4 5b 5e 5f 5d c3 55 89 e5 57 31 ff 56 May 15 07:13:00 Tower2 kernel: EIP: [<f82e525c>] xor_block+0x76/0x84 [md_mod] SS:ESP 0068:f63cbedc May 15 07:13:00 Tower2 kernel: ---[ end trace 6c2b49c6389e0999 ]--- This error occurs when adding a Western digital WD10EACS OR WD10EAVS as the 16th drive and the main web page hangs on "mounting..." However, adding a 300GB or 500GB Maxtor drive works fine with no errors. Any ideas?? Thanks in advance.

Joe, Thanks for the suggestion. I ran reiserfsck and it found no corruptions on disk12. Putting the array back to 15 disks eliminates the error. It only occurs when I try to expand the system past 15 drives.

Has anyone had problems adding more then 15 drives? I keep getting the following error in the syslog: May 15 07:13:00 Tower2 kernel: ReiserFS: md12: checking transaction log (md12) May 15 07:13:00 Tower2 kernel: BUG: unable to handle kernel paging request at 6d614e8e May 15 07:13:00 Tower2 kernel: IP: [<f82e525c>] xor_block+0x76/0x84 [md_mod] May 15 07:13:00 Tower2 kernel: *pdpt = 0000000002de0001 *pde = 0000000000000000 May 15 07:13:00 Tower2 kernel: Oops: 0000 [#1] SMP May 15 07:13:00 Tower2 kernel: last sysfs file: /sys/devices/pci0000:00/0000:00:1c.3/0000:03:00.0/ho st0/target0:4:0/0:4:0:0/block/sda/stat May 15 07:13:00 Tower2 kernel: Modules linked in: md_mod ata_piix sata_promise e1000 sata_sil24 liba ta May 15 07:13:00 Tower2 kernel: May 15 07:13:00 Tower2 kernel: Pid: 1906, comm: unraidd Not tainted (2.6.29.1-unRAID #2) May 15 07:13:00 Tower2 kernel: EIP: 0060:[<f82e525c>] EFLAGS: 00010202 CPU: 0 May 15 07:13:00 Tower2 kernel: EIP is at xor_block+0x76/0x84 [md_mod] May 15 07:13:00 Tower2 kernel: EAX: 00001000 EBX: 6d614e76 ECX: c2890000 EDX: c28fb000 May 15 07:13:00 Tower2 kernel: ESI: c2893000 EDI: c28fb000 EBP: f63cbefc ESP: f63cbedc May 15 07:13:00 Tower2 kernel: DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 May 15 07:13:00 Tower2 kernel: Process unraidd (pid: 1906, ti=f63ca000 task=f6fff740 task.ti=f63ca00 0) May 15 07:13:00 Tower2 kernel: Stack: May 15 07:13:00 Tower2 kernel: c2892000 c2893000 c2868000 6d614e76 00001000 00000001 c28f11e0 c28f1 3a0 May 15 07:13:00 Tower2 kernel: f63cbf3c f82e7474 00000001 00000005 00000011 00001000 00001000 f5aab 000 May 15 07:13:00 Tower2 kernel: c28fb000 c2890000 c2892000 c2893000 c2868000 c28f1910 00000000 c28f1 1e0 May 15 07:13:00 Tower2 kernel: Call Trace: May 15 07:13:00 Tower2 kernel: [<f82e7474>] ? compute_parity+0x101/0x2cc [md_mod] May 15 07:13:00 Tower2 kernel: [<f82e7ff0>] ? handle_stripe+0x8cc/0xc5a [md_mod] May 15 07:13:00 Tower2 kernel: [<c0344f57>] ? schedule+0x5e3/0x63c May 15 07:13:00 Tower2 kernel: [<f82e8804>] ? unraidd+0x9e/0xbc [md_mod] May 15 07:13:00 Tower2 kernel: [<f82e8766>] ? unraidd+0x0/0xbc [md_mod] May 15 07:13:00 Tower2 kernel: [<c01301bc>] ? kthread+0x3b/0x63 May 15 07:13:00 Tower2 kernel: [<c0130181>] ? kthread+0x0/0x63 May 15 07:13:00 Tower2 kernel: [<c01035db>] ? kernel_thread_helper+0x7/0x10 May 15 07:13:00 Tower2 kernel: Code: f8 8b 71 0c 89 45 ec 75 13 56 8b 45 f0 89 d1 53 8b 5d ec 89 fa ff 53 14 5a 59 eb 15 ff 71 10 89 d1 8b 45 f0 89 fa 56 53 8b 5d ec <ff> 53 18 83 c4 0c 8d 65 f4 5b 5e 5f 5d c3 55 89 e5 57 31 ff 56 May 15 07:13:00 Tower2 kernel: EIP: [<f82e525c>] xor_block+0x76/0x84 [md_mod] SS:ESP 0068:f63cbedc May 15 07:13:00 Tower2 kernel: ---[ end trace 6c2b49c6389e0999 ]--- When this happens the main web page hangs on "mounting".
