Hello, I have a netapp ds2246 connected to a Fujitsu PRIMERGY TX1320 M1 (running debian) via a LSI Logic SAS 9200-8E.
On the ds2246 I have installed some Seagate ST5000LM000-2AN170 and some Wester Digital WDC_WD50NPZZ-00A9JT0 disks.
On some of those disk I have performace problem (they are very slow, but no error message in the logs) . But if I remove the slow disk from the netapp Enclosure and connect it directly to the serve internal sata controller the performace are normal.
The strange thing is that this happen only with some drives.
Any idea of why this is happening ?
Regards
Albert
