Hi, This can be a hardware problem - hard to say. For some reason on one of the disks smart test is interrupted # 1 Extended offline Interrupted (host reset) 90% 12489 - # 2 Extended offline Interrupted (host reset) 90% 12484 - I see this in dmesg [ 4328.800100] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [ 4328.800129] ata3.00: failed command: WRITE DMA EXT [ 4328.800153] ata3.00: cmd 35/00:08:7e:dc:9f/00:00:2c:00:00/e0 tag 0 dma 4096 out [ 4328.800157] res 40/00:00:02:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) [ 4328.800190] ata3.00: status: { DRDY } [ 4333.849048] ata3: link is slow to respond, please be patient (ready=0) [ 4338.847048] ata3: device not ready (errno=-16), forcing hardreset [ 4338.847063] ata3: soft resetting link [ 4339.837375] ata3.00: configured for UDMA/133 [ 4339.837407] ata3: EH complete I'm using 2.6.37.2 with config based on an old rawhide 2.6.37. I have not noticed other problems with this disc. What might be causing this interrupts? -- Best regards, Michal http://eventhorizon.pl/ -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
