Hi list,
I can't solve the problem yet.
When I runnig the dmesg command, I have:
---
da0 at ahc0 bus 0 target 0 lun 0
da0: <SEAGATE ST39140LW 1483> Fixed Direct Access SCSI-2 device
da0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing
Enabled
da0: 8683MB (17783240 512 byte sectors: 255H 63S/T 1106C)
da1 at ahc0 bus 0 target 1 lun 0
da1: <SEAGATE ST39140LW 1483> Fixed Direct Access SCSI-2 device
da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing
Enabled
da1: 8683MB (17783240 512 byte sectors: 255H 63S/T 1106C)
---
I did a test, changing only the SCSI disk, using the same motherboard
(L440GX+). I ran the dmesg command again and I received:
--
da0 at ahc0 bus 0 target 0 lun 0
da0: <QUANTUM QM39100TD-SW N491> Fixed Direct Access SCSI-2 device
da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing
Enabled
da0: 8683MB (17783250 512 byte sectors: 255H 63S/T 1106C)
--
I realized that the quantum disk have a 80.000MB/s transfers.
Does someone use a SEAGATE ST39140LW disk and have I/O problems?
Regards,
Luiz Morte.
PS:
Someone told me that vipw doens't have much I/O disk, but when I run it
with 12000 accounts, my disk have a lot off access.
